Android Permission Dont Ask Me Again

Android M - cheque runtime permission - how to decide if the user checked "Never ask again"?

Question
Android M - check runtime permission - how to determine if the user checked "Never ask once again"?

Co-ordinate to this: http://developer.android.com/preview/features/runtime-permissions.html#coding an app can check for runtime permissions and request permissions if information technology hasn't been granted already. The post-obit dialog will be displayed so:

enter image description here

In example the user declines an of import permission, imo an app should display an explanation why the permission is needed and what impact declining has. That dialog has 2 options:

re-endeavour again (permission is requested again)
deny (app will work without that permission).

If the user checks Never inquire again however, the 2nd dialog with the explanation shouldn't be shown, especially if the user already declined once before. Now the question is: how does my app know whether the user has checked the Never ask over again? IMO the onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) doesn't give me that information.

A second question would exist: does Google take plans to incorporate a custom message in the permission dialog that would explicate why the app needs the permission? That way there would never exist a second dialog which would certainly brand for a meliorate ux.

Programmer Preview 2 brings some changes to how permissions are requested by the app (see likewise http://developer.android.com/preview/support.html#preview2-notes).

The first dialog now looks like this:

enter image description here

There's no "Never show once again" bank check-box (unlike developer preview ane). If the user denies the permission and if the permission is essential for the app it could present another dialog to explain the reason the app asks for that permission, e.g. like this:

enter image description here

If the user declines again the app should either shut down if information technology admittedly needs that permission or go along running with limited functionality. If the user reconsiders (and selects re-try), the permission is requested again. This fourth dimension the prompt looks like this:

enter image description here

The second time the "Never enquire once again" check-box is shown. If the user denies again and the check-box is ticked nothing more should happen. Whether or non the bank check-box is ticked can be adamant by using Activity.shouldShowRequestPermissionRationale(String), e.g. like this:

              if (shouldShowRequestPermissionRationale(Manifest.permission.WRITE_CONTACTS)) {...

That's what the Android documentation says (https://developer.android.com/training/permissions/requesting.html):

To help find the situations where you need to provide extra explanation, the system provides the Activity.shouldShowRequestPermissionRationale(String) method. This method returns truthful if the app has requested this permission previously and the user denied the asking. That indicates that you should probably explain to the user why you need the permission.

If the user turned downward the permission request in the by and chose the Don't inquire once again option in the permission request arrangement dialog, this method returns imitation. The method besides returns false if the device policy prohibits the app from having that permission.

To know if the user denied with "never ask again" you can check again the shouldShowRequestPermissionRationale method in your onRequestPermissionsResult when the user did not grant the permission.

              @Override public void onRequestPermissionsResult(int requestCode, Cord[] permissions, int[] grantResults) {     if (requestCode == REQUEST_PERMISSION) {         // for each permission cheque if the user granted/denied them         // you may want to grouping the rationale in a unmarried dialog,         // this is simply an instance         for (int i = 0, len = permissions.length; i < len; i++) {             String permission = permissions[i];             if (grantResults[i] == PackageManager.PERMISSION_DENIED) {             // user rejected the permission                 boolean showRationale = shouldShowRequestPermissionRationale( permission );                 if (! showRationale) {                     // user besides CHECKED "never ask again"                     // you tin either enable some autumn back,                     // disable features of your app                     // or open some other dialog explaining                     // over again the permission and directing to                     // the app setting                 } else if (Manifest.permission.WRITE_CONTACTS.equals(permission)) {                     showRationale(permission, R.string.permission_denied_contacts);                     // user did NOT check "never ask again"                     // this is a good identify to explain the user                     // why you need the permission and ask if he wants                     // to accept it (the rationale)                 } else if ( /* maybe cheque more permissions...*/ ) {                 }             }         }     } }

You can open your app setting with this code:

              Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS); Uri uri = Uri.fromParts("packet", getPackageName(), nil); intent.setData(uri); startActivityForResult(intent, REQUEST_PERMISSION_SETTING);

There is no way of sending the user directly to the Authority page.

You tin can check shouldShowRequestPermissionRationale() in your onRequestPermissionsResult().

shouldShowRequestPermissionRationale https://youtu.be/C8lUdPVSzDk?t=2m23s

Bank check whether permission was granted or not in onRequestPermissionsResult(). If not then check shouldShowRequestPermissionRationale().

If this method returns truthful and then testify an explanation that why this detail permission is needed. Then depending on user's choice again requestPermissions().
If information technology returns false and then show an mistake message that permission was not granted and app cannot proceed further or a particular characteristic is disabled.

Below is sample lawmaking.

              @Override public void onRequestPermissionsResult(int requestCode, @NonNull Cord[] permissions, @NonNull int[] grantResults) {     super.onRequestPermissionsResult(requestCode, permissions, grantResults);     switch (requestCode) {         case STORAGE_PERMISSION_REQUEST:             if (grantResults.length > 0                     && grantResults[0] == PackageManager.PERMISSION_GRANTED) {                 // permission was granted :)                 downloadFile();             } else {                 // permission was non granted                 if (getActivity() == null) {                     return;                 }                 if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.WRITE_EXTERNAL_STORAGE)) {                     showStoragePermissionRationale();                 } else {                     Snackbar snackbar = Snackbar.make(getView(), getResources().getString(R.string.message_no_storage_permission_snackbar), Snackbar.LENGTH_LONG);                     snackbar.setAction(getResources().getString(R.cord.settings), new View.OnClickListener() {                         @Override                         public void onClick(View v) {                             if (getActivity() == zero) {                                 return;                             }                             Intent intent = new Intent();                             intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);                             Uri uri = Uri.fromParts("parcel", getActivity().getPackageName(), naught);                             intent.setData(uri);                             OrderDetailFragment.this.startActivity(intent);                         }                     });                     snackbar.show();                 }             }             break;     } }

Apparently, google maps does exactly this for location permission.

Here is a nice and easy method to cheque the electric current permission condition:

                              @Retention(RetentionPolicy.SOURCE)     @IntDef({GRANTED, DENIED, BLOCKED_OR_NEVER_ASKED })     public @interface PermissionStatus {}      public static final int GRANTED = 0;     public static final int DENIED = one;     public static final int BLOCKED_OR_NEVER_ASKED = 2;      @PermissionStatus      public static int getPermissionStatus(Activity activeness, String androidPermissionName) {         if(ContextCompat.checkSelfPermission(action, androidPermissionName) != PackageManager.PERMISSION_GRANTED) {             if(!ActivityCompat.shouldShowRequestPermissionRationale(action, androidPermissionName)){                 render BLOCKED_OR_NEVER_ASKED;             }             return DENIED;         }         render GRANTED;     }

Caveat: returns BLOCKED_OR_NEVER_ASKED the first app start, before the user accepted/denied the permission through the user prompt (on sdk 23+ devices)

Update:

The Android support library now also seems to accept a very like grade android.support.v4.content.PermissionChecker which contains a checkSelfPermission() which returns:

              public static final int PERMISSION_GRANTED = 0; public static last int PERMISSION_DENIED = -1; public static final int PERMISSION_DENIED_APP_OP = -2;

Once the user has marked "Do non ask once again," the question can not be displayed over again. Merely information technology tin exist explained to the user that he has previously denied the permission and must grant permission in the settings. And reference him to the settings, with the following code:

              @Override public void onRequestPermissionsResult(int permsRequestCode, String[] permissions, int[] grantResults) {      if (grantResults.length > 0             && grantResults[0] == PackageManager.PERMISSION_GRANTED) {         // now, you have permission become ahead         // TODO: something      } else {          if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,                 Manifest.permission.READ_CALL_LOG)) {             // now, user has denied permission (but non permanently!)          } else {              // now, user has denied permission permanently!              Snackbar snackbar = Snackbar.make(findViewById(android.R.id.content), "You have previously declined this permission.\n" +                 "You lot must approve this permission in \"Permissions\" in the app settings on your device.", Snackbar.LENGTH_LONG).setAction("Settings", new View.OnClickListener() {             @Override             public void onClick(View view) {                  startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));              }         });         View snackbarView = snackbar.getView();         TextView textView = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);         textView.setMaxLines(5);  //Or as much as y'all need         snackbar.bear witness();          }      }     return; }

You can determine it by checking if permission rationale is to be shown inside the onRequestPermissionsResult() callback method. And if you find any permission ready to never ask once again, you can request users to grant permissions from the settings.

My full implementation would be like below. It works for both unmarried or multiple permissions requests. Utilise the post-obit or directly utilize my library.

              @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {     if(permissions.length == 0){         return;     }     boolean allPermissionsGranted = true;     if(grantResults.length>0){         for(int grantResult: grantResults){             if(grantResult != PackageManager.PERMISSION_GRANTED){                 allPermissionsGranted = false;                 break;             }         }     }     if(!allPermissionsGranted){         boolean somePermissionsForeverDenied = false;         for(String permission: permissions){             if(ActivityCompat.shouldShowRequestPermissionRationale(this, permission)){                 //denied                 Log.e("denied", permission);             }else{                 if(ActivityCompat.checkSelfPermission(this, permission) == PackageManager.PERMISSION_GRANTED){                     //allowed                     Log.eastward("allowed", permission);                 } else{                     //set to never enquire again                     Log.e("ready to never ask again", permission);                     somePermissionsForeverDenied = true;                 }             }         }         if(somePermissionsForeverDenied){             final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);             alertDialogBuilder.setTitle("Permissions Required")                     .setMessage("You have forcefully denied some of the required permissions " +                             "for this action. Please open settings, go to permissions and allow them.")                     .setPositiveButton("Settings", new DialogInterface.OnClickListener() {                         @Override                         public void onClick(DialogInterface dialog, int which) {                             Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS,                                     Uri.fromParts("bundle", getPackageName(), null));                             intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);                             startActivity(intent);                         }                     })                     .setNegativeButton("Abolish", new DialogInterface.OnClickListener() {                         @Override                         public void onClick(DialogInterface dialog, int which) {                         }                     })                     .setCancelable(false)                     .create()                     .bear witness();         }     } else {         switch (requestCode) {             //human action according to the request code used while requesting the permission(s).         }     } }

May exist useful for someone:--

What I have noticed is, if we cheque the shouldShowRequestPermissionRationale() flag in to onRequestPermissionsResult() callback method, it shows only 2 states.

Country 1:-Return true:-- Whatever time user clicks Deny permissions (including the very outset time).

Land ii:-Returns false :- if user selects "never asks once more".

~ Answered on 2016-02-19 01:47:38

If you lot want to detect all the "states" (starting time fourth dimension denied, just been denied, just been denied with "Never Inquire Once again" or permanently denied) you can do the following:

Create 2 Booleans:

              private boolean beforeClickPermissionRat; private boolean afterClickPermissionRat;

Fix the outset i before request for permission:

              beforeClickPermissionRat = shouldShowRequestPermissionRationale(Manifest.permission.READ_EXTERNAL_STORAGE);

Set the second one inside your onRequestPermissionsResult method:

              afterClickPermissionRat = shouldShowRequestPermissionRationale(Manifest.permission.READ_EXTERNAL_STORAGE);

Employ the following "truth table" to do whatever you need in onRequestPermissionsResult() (after checking that you still don't take the permission):

              // before after // False  FALSE  =  Was denied permanently, even so denied permanently --> App Settings // False  True   =  Beginning time deny, not denied permanently yet --> Zilch // True   FALSE  =  But been permanently denied --> Changing my caption to "Go to app settings to edit permissions" // TRUE   TRUE   =  Wasn't denied permanently, still non denied permanently --> Nothing

I had the aforementioned problem and I figured information technology out. To make life much simpler, I wrote an util form to handle runtime permissions.

              public class PermissionUtil {     /*     * Check if version is marshmallow and above.     * Used in deciding to enquire runtime permission     * */     public static boolean shouldAskPermission() {         render (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M);     } individual static boolean shouldAskPermission(Context context, String permission){         if (shouldAskPermission()) {             int permissionResult = ActivityCompat.checkSelfPermission(context, permission);             if (permissionResult != PackageManager.PERMISSION_GRANTED) {                 return true;             }         }         render false;     } public static void checkPermission(Context context, String permission, PermissionAskListener listener){ /*         * If permission is not granted         * */         if (shouldAskPermission(context, permission)){ /*             * If permission denied previously             * */             if (((Activeness)context).shouldShowRequestPermissionRationale(permission)) {                 listener.onPermissionPreviouslyDenied();             } else {                 /*                 * Permission denied or first time requested                 * */ if (PreferencesUtil.isFirstTimeAskingPermission(context, permission)) {                     PreferencesUtil.firstTimeAskingPermission(context, permission, false);                     listener.onPermissionAsk();                 } else {                     /*                     * Handle the feature without permission or ask user to manually allow permission                     * */                     listener.onPermissionDisabled();                 }             }         } else {             listener.onPermissionGranted();         }     } /*     * Callback on various cases on checking permission     *     * ane.

And the PreferenceUtil methods are every bit follows.

              public static void firstTimeAskingPermission(Context context, String permission, boolean isFirstTime){ SharedPreferences sharedPreference = context.getSharedPreferences(PREFS_FILE_NAME, MODE_PRIVATE;  sharedPreference.edit().putBoolean(permission, isFirstTime).utilise();  } public static boolean isFirstTimeAskingPermission(Context context, String permission){ render context.getSharedPreferences(PREFS_FILE_NAME, MODE_PRIVATE).getBoolean(permission, truthful); }

Now, all yous need is to use the method * checkPermission* with proper arguments.

Here is an example,

              PermissionUtil.checkPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE,                     new PermissionUtil.PermissionAskListener() {                         @Override                         public void onPermissionAsk() {                             ActivityCompat.requestPermissions(                                     thisActivity,               new String[]{Manifest.permission.READ_CONTACTS},                             REQUEST_EXTERNAL_STORAGE                             );                         } @Override                         public void onPermissionPreviouslyDenied() {                        //evidence a dialog explaining permission and then asking permission                         } @Override                         public void onPermissionDisabled() { Toast.makeText(context, "Permission Disabled.", Toast.LENGTH_SHORT).show();                         } @Override                         public void onPermissionGranted() {                             readContacts();                         }                     });

how does my app know whether the user has checked the "Never ask again"?

If user checked Never ask again, you lot'll get callback on onPermissionDisabled.

Happy coding :)

The method shouldShowRequestPermissionRationale() tin can be used to check whether the user selected the 'never asked over again' option and denied the permission. There's plenty of lawmaking examples, so I would rather explain how to use it for such a purpose, because I think its name and its implementation makes this more complicated that it actually is.

As explained in Requesting Permissions at Run Time, that method returns true if the option 'never inquire again' is visible, false otherwise; and then information technology returns false the very first fourth dimension a dialog is shown, and so from the second time on it returns true, and only if the user deny the permission selecting the option, at that point it returns simulated again.

To find such a case, either you can find the sequence faux-truthful-faux, or (more than simple) yous can have a flag which keeps track of the initial time the dialog is shown. After that, that method returns either true or false, where the false volition permit you to discover when the pick is selected.

A useful function to determine if an capricious permission has been blocked from requesting (in Kotlin):

              private fun isPermissionBlockedFromAsking(activity: Activeness, permission: String): Boolean {     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {         return ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED             && !activity.shouldShowRequestPermissionRationale(permission)             && PreferenceManager.getDefaultSharedPreferences(activity).getBoolean(permission, fake)     }     return fake }

Employ of this requires setting a shared preference boolean with the name of your desired permission (east.yard. android.Manifest.permission.READ_PHONE_STATE) to true when you kickoff request a permission.

Explanation:

Build.VERSION.SDK_INT >= Build.VERSION_CODES.Thou as some of the code may only be run on API level 23+.

ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED to check we don't already accept the permission.

!activeness.shouldShowRequestPermissionRationale(permission) to check whether the user has denied the app asking again. Due to quirks of this office, the following line is also required.

PreferenceManager.getDefaultSharedPreferences(activity).getBoolean(permission, false) this is used (along with setting the value to true on kickoff permission asking) to distinguish betwixt the "Never asked" and "Never enquire again" states, as the previous line doesn't render this information.

Please don't throw stones at me for this solution.

This works but is a chip "hacky".

When you lot call requestPermissions, register the current fourth dimension.

                              mAskedPermissionTime = Arrangement.currentTimeMillis();

So in onRequestPermissionsResult

if the upshot is not granted, check the time again.

                              if (System.currentTimeMillis() - mAskedPermissionTime < 100)

Since the user did cannot maybe click so fast on the deny button, we know that he selected "never ask again" because the callback is instant.

Use at your own risks.

I wrote a shorthand for permission request in Android M. This code also handles backwards compatibility to older Android versions.

All the ugly lawmaking is extracted into a Fragment which attaches and detaches itself to the Action requesting the permissions.You can use PermissionRequestManager as post-obit:

              new PermissionRequestManager()         // We need a AppCompatActivity here, if y'all are not using back up libraries yous will have to slightly change          // the PermissionReuqestManager class         .withActivity(this)          // List all permissions you need         .withPermissions(android.Manifest.permission.CALL_PHONE, android.Manifest.permission.READ_CALENDAR)          // This Runnable is called whenever the request was successfull         .withSuccessHandler(new Runnable() {             @Override             public void run() {                 // Practise something with your permissions!                 // This is chosen later on the user has granted all                  // permissions, we are 1 a older platform where                  // the user does not need to grant permissions                  // manually, or all permissions are already granted              }         })          // Optional, called when the user did not grant all permissions         .withFailureHandler(new Runnable() {             @Override             public void run() {                 // This is called if the user has rejected ane or all of the requested permissions                 L.e(this.getClass().getSimpleName(), "Unable to request permission");              }         })          // After calling this, the user is prompted to grant the rights         .asking();

Instead you will receive callback on onRequestPermissionsResult() as PERMISSION_DENIED when you request permission again while falling in false condition of shouldShowRequestPermissionRationale()

From Android doctor:

When the system asks the user to grant a permission, the user has the option of telling the system non to inquire for that permission again. In that case, any time an app uses requestPermissions() to inquire for that permission again, the system immediately denies the request. The arrangement calls your onRequestPermissionsResult() callback method and passes PERMISSION_DENIED, the same way it would if the user had explicitly rejected your asking again. This ways that when yous call requestPermissions(), you cannot assume that any direct interaction with the user has taken place.

Effort this simple permission library. It will handle all operations related to permission in 3 piece of cake steps. Information technology saved my time. You can terminate all permission related work in 15 mins.

It tin can handle Deny, Information technology can handle Never inquire again, It tin can call app settings for permission, It can give a Rational message, Information technology can give a Deprival message, It can give a list of accepted permissions, Information technology can give a list of denied permissions and etc.

https://github.com/ParkSangGwon/TedPermission

Pace 1: add your dependency

              dependencies {      compile 'gun0912.ted:tedpermission:2.one.one'      //check the higher up link for latest libraries }

Step2: Enquire permissions

              TedPermission.with(this)     .setPermissionListener(permissionlistener)     .setDeniedMessage("If you reject permission,you can non use this service\n\nPlease turn on permissions at [Setting] > [Permission]")     .setPermissions(Manifest.permission.READ_CONTACTS, Manifest.permission.ACCESS_FINE_LOCATION)     .check();

Pace 3: Handle permission response

              PermissionListener permissionlistener = new PermissionListener() {     @Override     public void onPermissionGranted() {         Toast.makeText(MainActivity.this, "Permission Granted", Toast.LENGTH_SHORT).show();     }      @Override     public void onPermissionDenied(ArrayList<String> deniedPermissions) {         Toast.makeText(MainActivity.this, "Permission Denied\due north" + deniedPermissions.toString(), Toast.LENGTH_SHORT).show();     } };

You tin can employ

              shouldShowRequestPermissionRationale()

within

              onRequestPermissionsResult()

See the example beneath:

Check if it has permission when the user clicks the push:

              @Override public void onClick(View 5) {     if (five.getId() == R.id.appCompatBtn_changeProfileCoverPhoto) {         if (Build.VERSION.SDK_INT < 23) { // API < 23 don't need to ask permission             navigateTo(MainActivity.course); // Navigate to action to change photos         } else {             if (ContextCompat.checkSelfPermission(SettingsActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)                     != PackageManager.PERMISSION_GRANTED) {                 // Permission is not granted yet. Ask for permission...                 requestWriteExternalPermission();             } else {                 // Permission is already granted, good to go :)                 navigateTo(MainActivity.form);             }         }      } }

When the user respond the permission dialog box we volition become to onRequestPermissionResult:

              @Override public void onRequestPermissionsResult(int requestCode, @NonNull Cord[] permissions, @NonNull int[] grantResults) {     super.onRequestPermissionsResult(requestCode, permissions, grantResults);      if (requestCode == WRITE_EXTERNAL_PERMISSION_REQUEST_CODE) {         // Example ane. Permission is granted.           if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {               if (ContextCompat.checkSelfPermission(SettingsActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)                     == PackageManager.PERMISSION_GRANTED) {                 // Before navigating, I nevertheless check one more than time the permission for good practice.                 navigateTo(MainActivity.grade);             }         } else { // Case 2.

I would as well similar to obtain the information whether or non the user has selected "never enquire once again". I have achieved a 'almost solution' with an ugly looking flag, but before I tell you how, I will tell you almost my motivation:

I would like to offer the permission referring functionality initially. If the user uses information technology and has no rights, he/she gets the either the 1th dialog from above or both the 2d and 3rd. When the user has chosen 'Never ask again' I would similar to disable the functionality and to display it differently. - My action is triggered by a spinner text entry, I would also similar to add '(Permission revoked)' to the characterization text displayed. This shows to the user: 'There is functionality merely I cannot apply it, due to my permission settings.' However, this does non seem to be possible, as I cannot bank check whether or non 'Never enquire once more' has been chosen.

I came to a solution I can live with by having my functionality ever enabled with an active permission check. I am showing a Toast bulletin in onRequestPermissionsResult() in case of a negative response only merely if I have non shown my custom rationale popup. So if the user has chosen 'Never ask again' he gets a toast message but. If the user is reluctant to chose 'never enquire again' he gets merely the custom rationale and the permission request popup by the functioning system merely not toast, as three notifications in a row would be too much pain.

Expanding on mVck'due south answer above, the following logic determines whether "Never enquire over again" has been checked for a given Permission Asking:

                              if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)                                 || ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)                                 || ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)                                 || ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.RECORD_AUDIO)) {                             showDialogOK("Service Permissions are required for this app",                                     new DialogInterface.OnClickListener() {                                         @Override                                         public void onClick(DialogInterface dialog, int which) {                                             switch (which) {                                                 case DialogInterface.BUTTON_POSITIVE:                                                     checkAndRequestPermissions();                                                     pause;                                                 case DialogInterface.BUTTON_NEGATIVE:                                                     // keep with logic by disabling the related features or quit the app.                                                     end();                                                     intermission;                                             }                                         }                                     });                         }                         //permission is denied (and never ask over again is  checked)                         //shouldShowRequestPermissionRationale will return false                         else {                             explain("You need to requite some mandatory permissions to continue. Do you want to get to app settings?");                             //                            //proceed with logic by disabling the related features or quit the app.                         }

explain() method

              private void explain(String msg){         terminal android.support.v7.app.AlertDialog.Architect dialog = new android.back up.v7.app.AlertDialog.Builder(this);         dialog.setMessage(msg)                 .setPositiveButton("Yep", new DialogInterface.OnClickListener() {                     @Override                     public void onClick(DialogInterface paramDialogInterface, int paramInt) {                         //  permissionsclass.requestPermission(type,code);                         startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("packet:com.exampledemo.parsaniahardik.marshmallowpermission")));                     }                 })                 .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {                     @Override                     public void onClick(DialogInterface paramDialogInterface, int paramInt) {                         finish();                     }                 });         dialog.show();     }

Above code will too prove dialog, which will redirect user to app settings screen from where he can give permission if had checked never ask again button.

I have to implement dynamic permission for photographic camera. Where 3 possible cases occurs: one. Allow, two. Denied, 3. Don't ask again.

                              @Override     public void onRequestPermissionsResult(int requestCode, @NonNull Cord[] permissions, @NonNull int[] grantResults) {      for (Cord permission : permissions) {         if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permission)) {             //denied             Log.e("denied", permission);         } else {             if (ActivityCompat.checkSelfPermission(getActivity(), permission) == PackageManager.PERMISSION_GRANTED) {                 //immune                 Log.e("allowed", permission);             } else {                 //set up to never ask once more                 Log.due east("set to never ask once again", permission);                 //do something here.             }         }     }     if (requestCode != MaterialBarcodeScanner.RC_HANDLE_CAMERA_PERM) {         super.onRequestPermissionsResult(requestCode, permissions, grantResults);         return;     }     if (grantResults.length != 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {         mScannerView.setResultHandler(this);         mScannerView.startCamera(mCameraId);         mScannerView.setFlash(mFlash);         mScannerView.setAutoFocus(mAutoFocus);         return;     } else {         //fix to never ask once again         Log.eastward("set to never ask again", permissions[0]);     }     DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() {         public void onClick(DialogInterface dialog, int id) {             dialog.cancel();         }     };     AlertDialog.Architect architect = new AlertDialog.Architect(getActivity());     builder.setTitle("Fault")             .setMessage(R.string.no_camera_permission)             .setPositiveButton(android.R.string.ok, listener)             .show();   }  individual void insertDummyContactWrapper() {         int hasWriteContactsPermission = checkSelfPermission(Manifest.permission.Photographic camera);         if (hasWriteContactsPermission != PackageManager.PERMISSION_GRANTED) {             requestPermissions(new String[]{Manifest.permission.Photographic camera},                     REQUEST_CODE_ASK_PERMISSIONS);             render;         }         mScannerView.setResultHandler(this);         mScannerView.startCamera(mCameraId);         mScannerView.setFlash(mFlash);         mScannerView.setAutoFocus(mAutoFocus);     }  private int checkSelfPermission(Cord camera) {     if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.Photographic camera)             != PackageManager.PERMISSION_GRANTED) {         render REQUEST_CODE_ASK_PERMISSIONS;     } else {         return REQUEST_NOT_CODE_ASK_PERMISSIONS;     } }

OnRequestPermissionResult-complimentary and shouldShowRequestPermissionRationale-costless method:

              public static void requestDangerousPermission(AppCompatActivity action, String permission) {         if (hasPermission(action, permission)) return;         requestPermission();          new Handler().postDelayed(() -> {             if (activity.getLifecycle().getCurrentState() == Lifecycle.State.RESUMED) {                 Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);                 intent.setData(Uri.parse("package:" + context.getPackageName()));                 context.startActivity(intent);             }         }, 250);     }

Opens device settings after 250ms if no permission popup happened (which is the instance if 'Never ask once again' was selected.

To respond the question precisely, What happens when user presses "Never Ask Again"?

The overridden method / function

              onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray)

The grantResult assortment comes out to be Empty, then you can practice something there possibly? But not the best practice.

How to Handle "Never Ask Again"?

I am working with Fragment, which required READ_EXTERNAL_STORAGE permission.

              override fun onViewCreated(view: View, savedInstanceState: Packet?) {         super.onViewCreated(view, savedInstanceState)          when {             isReadPermissionsGranted() -> {                  /**                  * Permissions has been Granted                  */                  getDirectories()             }              isPermissionDeniedBefore() -> {                  /**                  * User has denied before, explicate why we need the permission and ask again                  */                  updateUIForDeniedPermissions()                 checkIfPermissionIsGrantedNow()              }             else -> {                  /**                  * Need to ask For Permissions, First Time                  */                  checkIfPermissionIsGrantedNow()                  /**                  * If user selects, "Dont Ask Once again" information technology will never ask again! so just update the UI for Denied Permissions                  */                  updateUIForDeniedPermissions()              }         }     }

The other functions are trivial.

              // Is Read Write Permissions Granted fun isReadWritePermissionGranted(context: Context): Boolean {     return (ContextCompat.checkSelfPermission(         context as Activity,         Manifest.permission.READ_EXTERNAL_STORAGE     ) == PackageManager.PERMISSION_GRANTED) and             (ContextCompat.checkSelfPermission(                 context,                 Manifest.permission.WRITE_EXTERNAL_STORAGE             ) == PackageManager.PERMISSION_GRANTED) }  fun isReadPermissionDenied(context: Context) : Boolean {     return ActivityCompat.shouldShowRequestPermissionRationale(         context as Activeness,         PermissionsUtils.READ_EXTERNAL_STORAGE_PERMISSIONS) }
