Check if User Says Never Show Again Permissions Android
Android M - check runtime permission - how to decide if the user checked "Never ask once more"?
- Home
- Question
- Android Grand - check runtime permission - how to determine if the user checked "Never enquire once again"?
According to this: http://developer.android.com/preview/features/runtime-permissions.html#coding an app tin check for runtime permissions and request permissions if it hasn't been granted already. The following dialog will exist displayed then:
In case the user declines an important permission, imo an app should display an caption why the permission is needed and what impact declining has. That dialog has two options:
- re-try again (permission is requested again)
- deny (app will work without that permission).
If the user checks Never enquire over again yet, the second dialog with the explanation shouldn't be shown, particularly if the user already declined once before. Now the question is: how does my app know whether the user has checked the Never ask once more? IMO the onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) doesn't give me that information.
A second question would exist: does Google have plans to incorporate a custom message in the permission dialog that would explain why the app needs the permission? That mode in that location would never exist a 2d dialog which would certainly make for a amend ux.

Developer Preview two brings some changes to how permissions are requested by the app (see too http://developer.android.com/preview/back up.html#preview2-notes).
The first dialog now looks similar this:
There'southward no "Never bear witness once more" cheque-box (unlike developer preview ane). If the user denies the permission and if the permission is essential for the app it could nowadays another dialog to explain the reason the app asks for that permission, due east.grand. like this:
If the user declines again the app should either shut downward if it absolutely needs that permission or go on running with limited functionality. If the user reconsiders (and selects re-try), the permission is requested again. This time the prompt looks like this:
The second fourth dimension the "Never ask again" bank check-box is shown. If the user denies again and the check-box is ticked nothing more should happen. Whether or not the check-box is ticked can be determined by using Activity.shouldShowRequestPermissionRationale(String), e.g. like this:
if (shouldShowRequestPermissionRationale(Manifest.permission.WRITE_CONTACTS)) {... That'southward what the Android documentation says (https://programmer.android.com/grooming/permissions/requesting.html):
To assistance find the situations where you need to provide actress caption, the system provides the Action.shouldShowRequestPermissionRationale(String) method. This method returns true if the app has requested this permission previously and the user denied the request. That indicates that yous should probably explicate to the user why you lot need the permission.
If the user turned down the permission request in the past and chose the Don't ask again selection in the permission request system dialog, this method returns false. The method also returns false if the device policy prohibits the app from having that permission.
To know if the user denied with "never enquire 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, String[] permissions, int[] grantResults) { if (requestCode == REQUEST_PERMISSION) { // for each permission check if the user granted/denied them // you may desire to group the rationale in a single dialog, // this is just 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 as well CHECKED "never ask again" // yous can either enable some fall back, // disable features of your app // or open another dialog explaining // once 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 bank check "never enquire once more" // this is a skilful place to explain the user // why yous need the permission and inquire if he wants // to accept it (the rationale) } else if ( /* perchance 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("package", getPackageName(), null); intent.setData(uri); startActivityForResult(intent, REQUEST_PERMISSION_SETTING); There is no way of sending the user directly to the Authorization page.

You tin check shouldShowRequestPermissionRationale() in your onRequestPermissionsResult().
https://youtu.exist/C8lUdPVSzDk?t=2m23s
Check whether permission was granted or not in onRequestPermissionsResult(). If not then check shouldShowRequestPermissionRationale().
- If this method returns
truthfulthen testify an explanation that why this particular permission is needed. Then depending on user's choice againrequestPermissions(). - If it returns
fakethen show an fault message that permission was not granted and app cannot proceed further or a particular feature is disabled.
Below is sample lawmaking.
@Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] 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() == aught) { 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.string.settings), new View.OnClickListener() { @Override public void onClick(View v) { if (getActivity() == cipher) { return; } Intent intent = new Intent(); intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS); Uri uri = Uri.fromParts("package", getActivity().getPackageName(), cipher); intent.setData(uri); OrderDetailFragment.this.startActivity(intent); } }); snackbar.show(); } } break; } } Patently, google maps does exactly this for location permission.

Here is a nice and easy method to check the current permission status:
@Retentiveness(RetentionPolicy.SOURCE) @IntDef({GRANTED, DENIED, BLOCKED_OR_NEVER_ASKED }) public @interface PermissionStatus {} public static last int GRANTED = 0; public static final int DENIED = 1; public static final int BLOCKED_OR_NEVER_ASKED = 2; @PermissionStatus public static int getPermissionStatus(Activity activity, String androidPermissionName) { if(ContextCompat.checkSelfPermission(activity, androidPermissionName) != PackageManager.PERMISSION_GRANTED) { if(!ActivityCompat.shouldShowRequestPermissionRationale(activity, androidPermissionName)){ render BLOCKED_OR_NEVER_ASKED; } return DENIED; } return GRANTED; } Caveat: returns BLOCKED_OR_NEVER_ASKED the first app start, earlier the user accustomed/denied the permission through the user prompt (on sdk 23+ devices)
Update:
The Android support library now too seems to take a very like course android.support.v4.content.PermissionChecker which contains a checkSelfPermission() which returns:
public static last int PERMISSION_GRANTED = 0; public static terminal int PERMISSION_DENIED = -i; public static final int PERMISSION_DENIED_APP_OP = -2; ~ Answered on 2016-01-26 11:46:26
Once the user has marked "Practise not enquire again," the question tin not be displayed again. But it can be 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 take permission become alee // TODO: something } else { if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, Manifest.permission.READ_CALL_LOG)) { // now, user has denied permission (just not permanently!) } else { // at present, user has denied permission permanently!

Yous can decide it past checking if permission rationale is to exist shown inside the onRequestPermissionsResult() callback method. And if you lot find whatever permission set to never ask again, y'all tin can request users to grant permissions from the settings.
My full implementation would be similar below. It works for both single or multiple permissions requests. Use the post-obit or directly use 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 = imitation; break; } } } if(!allPermissionsGranted){ boolean somePermissionsForeverDenied = faux; for(String permission: permissions){ if(ActivityCompat.shouldShowRequestPermissionRationale(this, permission)){ //denied Log.eastward("denied", permission); }else{ if(ActivityCompat.checkSelfPermission(this, permission) == PackageManager.PERMISSION_GRANTED){ //immune Log.e("allowed", permission); } else{ //fix to never enquire once more Log.e("set to never ask again", permission); somePermissionsForeverDenied = truthful; } } } if(somePermissionsForeverDenied){ final AlertDialog.Architect alertDialogBuilder = new AlertDialog.Builder(this); alertDialogBuilder.setTitle("Permissions Required") .setMessage("Y'all have forcefully denied some of the required permissions " + "for this action. Please open settings, get 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("packet", getPackageName(), null)); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); } }) .setNegativeButton("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }) .setCancelable(fake) .create() .bear witness(); } } else { switch (requestCode) { //act co-ordinate to the request code used while requesting the permission(s). } } } ~ Answered on 2016-12-22 17:02:49
May be useful for someone:--
What I have noticed is, if we check the shouldShowRequestPermissionRationale() flag in to onRequestPermissionsResult() callback method, it shows only 2 states.
State 1:-Return true:-- Whatsoever time user clicks Deny permissions (including the very first fourth dimension).
State 2:-Returns faux :- if user selects "never asks again".

If you want to detect all the "states" (get-go time denied, just been denied, simply been denied with "Never Enquire Again" or permanently denied) you can exercise the post-obit:
Create ii Booleans:
private boolean beforeClickPermissionRat; private boolean afterClickPermissionRat; Fix the starting time i earlier asking for permission:
beforeClickPermissionRat = shouldShowRequestPermissionRationale(Manifest.permission.READ_EXTERNAL_STORAGE); Set the 2nd one inside your onRequestPermissionsResult method:
afterClickPermissionRat = shouldShowRequestPermissionRationale(Manifest.permission.READ_EXTERNAL_STORAGE); Apply the following "truth table" to do whatsoever you need in onRequestPermissionsResult() (after checking that you nevertheless don't take the permission):
// earlier after // Simulated Fake = Was denied permanently, however denied permanently --> App Settings // Simulated True = First time deny, non denied permanently yet --> Nothing // TRUE FALSE = Just been permanently denied --> Changing my explanation to "Go to app settings to edit permissions" // TRUE True = Wasn't denied permanently, yet not denied permanently --> Nothing ~ Answered on 2016-12-23 sixteen:18:18
I had the same problem and I figured it out. To make life much simpler, I wrote an util class to handle runtime permissions.
public form PermissionUtil { /* * Check if version is marshmallow and to a higher place. * Used in deciding to enquire runtime permission * */ public static boolean shouldAskPermission() { return (Build.VERSION.SDK_INT >= Build.VERSION_CODES.1000); } private static boolean shouldAskPermission(Context context, Cord permission){ if (shouldAskPermission()) { int permissionResult = ActivityCompat.checkSelfPermission(context, permission); if (permissionResult != PackageManager.PERMISSION_GRANTED) { render true; } } return 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 (((Activity)context).shouldShowRequestPermissionRationale(permission)) { listener.onPermissionPreviouslyDenied(); } else { /* * Permission denied or first time requested * */ if (PreferencesUtil.isFirstTimeAskingPermission(context, permission)) { PreferencesUtil.firstTimeAskingPermission(context, permission, faux); listener.onPermissionAsk(); } else { /* * Handle the characteristic without permission or ask user to manually allow permission * */ listener.onPermissionDisabled(); } } } else { listener.onPermissionGranted(); } } /* * Callback on diverse cases on checking permission * * 1. Beneath M, runtime permission not needed. In that example onPermissionGranted() would be called. * If permission is already granted, onPermissionGranted() would be called. * * ii. Above K, if the permission is being asked showtime time onPermissionAsk() would be chosen. * * 3. Higher up M, if the permission is previously asked only not granted, onPermissionPreviouslyDenied() * would be called. * * four. Above M, if the permission is disabled by device policy or the user checked "Never inquire again" * cheque box on previous request permission, onPermissionDisabled() would be called. * */ public interface PermissionAskListener { /* * Callback to ask permission * */ void onPermissionAsk(); /* * Callback on permission denied * */ void onPermissionPreviouslyDenied(); /* * Callback on permission "Never show once more" checked and denied * */ void onPermissionDisabled(); /* * Callback on permission granted * */ void onPermissionGranted(); } } And the PreferenceUtil methods are equally 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).utilize(); } public static boolean isFirstTimeAskingPermission(Context context, String permission){ render context.getSharedPreferences(PREFS_FILE_NAME, MODE_PRIVATE).getBoolean(permission, true); } Now, all you need is to utilize 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() { //testify a dialog explaining permission and and so request permission } @Override public void onPermissionDisabled() { Toast.makeText(context, "Permission Disabled.", Toast.LENGTH_SHORT).testify(); } @Override public void onPermissionGranted() { readContacts(); } }); how does my app know whether the user has checked the "Never ask once more"?
If user checked Never inquire again, you'll get callback on onPermissionDisabled.
Happy coding :)

The method shouldShowRequestPermissionRationale() can exist used to check whether the user selected the 'never asked again' selection and denied the permission. At that place's plenty of code examples, then I would rather explain how to use information technology 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 Fourth dimension, that method returns true if the option 'never ask again' is visible, false otherwise; and so it returns false the very first time a dialog is shown, then from the second fourth dimension on it returns true, and only if the user deny the permission selecting the choice, at that betoken it returns imitation once more.
To detect such a instance, either you lot can detect the sequence false-truthful-fake, or (more than elementary) yous tin can have a flag which keeps rails of the initial time the dialog is shown. Afterwards that, that method returns either true or fake, where the false volition allow you to detect 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: Action, permission: String): Boolean { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Thousand) { render ContextCompat.checkSelfPermission(action, permission) != PackageManager.PERMISSION_GRANTED && !activity.shouldShowRequestPermissionRationale(permission) && PreferenceManager.getDefaultSharedPreferences(activity).getBoolean(permission, false) } return fake } Use of this requires setting a shared preference boolean with the name of your desired permission (due east.thousand. android.Manifest.permission.READ_PHONE_STATE) to true when you lot showtime request a permission.
Explanation:
Build.VERSION.SDK_INT >= Build.VERSION_CODES.Thousand equally some of the lawmaking may only be run on API level 23+.
ContextCompat.checkSelfPermission(activeness, permission) != PackageManager.PERMISSION_GRANTED to check nosotros don't already have the permission.
!activity.shouldShowRequestPermissionRationale(permission) to check whether the user has denied the app asking once again. Due to quirks of this function, the following line is as well required.
PreferenceManager.getDefaultSharedPreferences(action).getBoolean(permission, false) this is used (forth with setting the value to true on starting time permission request) to distinguish between the "Never asked" and "Never ask 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 bit "hacky".
When you call requestPermissions, register the current time.
mAskedPermissionTime = System.currentTimeMillis(); Then in onRequestPermissionsResult
if the upshot is not granted, check the time again.
if (Arrangement.currentTimeMillis() - mAskedPermissionTime < 100) Since the user did cannot perchance click and then fast on the deny push, we know that he selected "never inquire over again" because the callback is instant.
Employ at your own risks.

I wrote a shorthand for permission asking in Android Thousand. This code also handles backwards compatibility to older Android versions.
All the ugly code is extracted into a Fragment which attaches and detaches itself to the Activity requesting the permissions.You lot can use PermissionRequestManager equally following:
new PermissionRequestManager() // We need a AppCompatActivity here, if yous are not using back up libraries you volition 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() { // Exercise something with your permissions! // This is called afterward the user has granted all // permissions, nosotros are i a older platform where // the user does not need to grant permissions // manually, or all permissions are already granted } }) // Optional, chosen when the user did not grant all permissions .withFailureHandler(new Runnable() { @Override public void run() { // This is called if the user has rejected i or all of the requested permissions L.eastward(this.getClass().getSimpleName(), "Unable to request permission"); } }) // Afterwards calling this, the user is prompted to grant the rights .asking(); Take a await: https://gist.github.com/crysxd/385b57d74045a8bd67c4110c34ab74aa

Instead you will receive callback on onRequestPermissionsResult() as PERMISSION_DENIED when you request permission again while falling in false status of shouldShowRequestPermissionRationale()
From Android doc:
When the system asks the user to grant a permission, the user has the option of telling the system not to ask for that permission again. In that case, any fourth dimension an app uses requestPermissions() to ask for that permission again, the organization immediately denies the asking. The organisation calls your onRequestPermissionsResult() callback method and passes PERMISSION_DENIED, the same way it would if the user had explicitly rejected your request again. This means that when you lot call requestPermissions(), yous cannot presume that any directly interaction with the user has taken identify.

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

You can use

I would also like 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, simply earlier I tell you how, I volition tell you most my motivation:
I would like to offering 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 enquire again' I would like to disable the functionality and to display it differently. - My action is triggered by a spinner text entry, I would also like to add '(Permission revoked)' to the label text displayed. This shows to the user: 'At that place is functionality but I cannot use information technology, due to my permission settings.' However, this does not seem to be possible, as I cannot check whether or non 'Never enquire again' has been chosen.
I came to a solution I can live with past having my functionality always enabled with an active permission check. I am showing a Toast message in onRequestPermissionsResult() in case of a negative response just just if I have non shown my custom rationale popup. So if the user has called 'Never inquire over again' he gets a toast bulletin only. If the user is reluctant to chose 'never enquire again' he gets only the custom rationale and the permission request popup past the operation organisation but not toast, as 3 notifications in a row would be too much pain.

Expanding on mVck's answer higher up, the following logic determines whether "Never ask again" has been checked for a given Permission Asking:
bool bStorage = grantResults[0] == Permission.Granted; bool bNeverAskForStorage = !bStorage && ( _bStorageRationaleBefore == true && _bStorageRationaleAfter == fake || _bStorageRationaleBefore == false && _bStorageRationaleAfter == faux ); which is excerpted from below (for the full example see this answer)
private bool _bStorageRationaleBefore; private bool _bStorageRationaleAfter; private const int ANDROID_PERMISSION_REQUEST_CODE__SDCARD = two; //individual const int ANDROID_PERMISSION_REQUEST_CODE__CAMERA = 1; private const int ANDROID_PERMISSION_REQUEST_CODE__NONE = 0; public override void OnRequestPermissionsResult(int requestCode, string[] permissions, [GeneratedEnum] Permission[] grantResults) { base.OnRequestPermissionsResult(requestCode, permissions, grantResults); switch (requestCode) { example ANDROID_PERMISSION_REQUEST_CODE__SDCARD: _bStorageRationaleAfter = ShouldShowRequestPermissionRationale(Android.Manifest.Permission.WriteExternalStorage); bool bStorage = grantResults[0] == Permission.Granted; bool bNeverAskForStorage = !bStorage && ( _bStorageRationaleBefore == true && _bStorageRationaleAfter == false || _bStorageRationaleBefore == false && _bStorageRationaleAfter == false ); pause; } } private List<string> GetRequiredPermissions(out int requestCode) { // Android v6 requires explicit permission granting from user at runtime for security reasons requestCode = ANDROID_PERMISSION_REQUEST_CODE__NONE; // 0 List<string> requiredPermissions = new Listing<cord>(); _bStorageRationaleBefore = ShouldShowRequestPermissionRationale(Android.Manifest.Permission.WriteExternalStorage); Permission writeExternalStoragePerm = ApplicationContext.CheckSelfPermission(Android.Manifest.Permission.WriteExternalStorage); //if(extStoragePerm == Permission.Denied) if (writeExternalStoragePerm != Permission.Granted) { requestCode |= ANDROID_PERMISSION_REQUEST_CODE__SDCARD; requiredPermissions.Add(Android.Manifest.Permission.WriteExternalStorage); } return requiredPermissions; } protected override void OnCreate(Bundle savedInstanceState) { base of operations.OnCreate(savedInstanceState); // Android v6 requires explicit permission granting from user at runtime for security reasons int requestCode; List<cord> requiredPermissions = GetRequiredPermissions(out requestCode); if (requiredPermissions != null && requiredPermissions.Count > 0) { if (requestCode >= ANDROID_PERMISSION_REQUEST_CODE__SDCARD) { _savedInstanceState = savedInstanceState; RequestPermissions(requiredPermissions.ToArray(), requestCode); return; } } } OnCreate2(savedInstanceState); } ~ Answered on 2017-07-26 12:44:54
You can employ if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.Photographic camera) method to observe whether never enquire is checked or not.
For more reference : Check this
To check for multiple permissions utilise:
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) { example DialogInterface.BUTTON_POSITIVE: checkAndRequestPermissions(); break; case DialogInterface.BUTTON_NEGATIVE: // proceed with logic by disabling the related features or quit the app. finish(); pause; } } }); } //permission is denied (and never ask once more is checked) //shouldShowRequestPermissionRationale will return false else { explicate("You demand to requite some mandatory permissions to continue. Exercise you desire to get to app settings?"); // //keep with logic by disabling the related features or quit the app. } explain() method
private void explicate(String msg){ final android.support.v7.app.AlertDialog.Builder dialog = new android.support.v7.app.AlertDialog.Architect(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.prove(); } Above code will also prove dialog, which volition redirect user to app settings screen from where he can give permission if had checked never inquire over again push button.

I take to implement dynamic permission for camera. Where iii possible cases occurs: i. Allow, 2. 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) { //allowed Log.e("allowed", permission); } else { //prepare to never ask over again Log.due east("set to never ask over again", permission); //exercise 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); render; } else { //set to never ask again Log.e("ready to never ask again", permissions[0]); } DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }; AlertDialog.Builder builder = new AlertDialog.Builder(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.CAMERA); if (hasWriteContactsPermission != PackageManager.PERMISSION_GRANTED) { requestPermissions(new String[]{Manifest.permission.CAMERA}, REQUEST_CODE_ASK_PERMISSIONS); return; } mScannerView.setResultHandler(this); mScannerView.startCamera(mCameraId); mScannerView.setFlash(mFlash); mScannerView.setAutoFocus(mAutoFocus); } private int checkSelfPermission(String camera) { if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.Photographic camera) != PackageManager.PERMISSION_GRANTED) { return REQUEST_CODE_ASK_PERMISSIONS; } else { render REQUEST_NOT_CODE_ASK_PERMISSIONS; } } ~ Answered on 2017-03-21 09:59:23
OnRequestPermissionResult-free and shouldShowRequestPermissionRationale-free method:
public static void requestDangerousPermission(AppCompatActivity activity, Cord permission) { if (hasPermission(activity, 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 subsequently 250ms if no permission popup happened (which is the case if 'Never ask again' was selected.

To answer the question precisely, What happens when user presses "Never Ask Again"?
The overridden method / function
onRequestPermissionsResult(requestCode: Int, permissions: Assortment<out Cord>, grantResults: IntArray) The grantResult array comes out to be Empty, so you tin can do something there possibly? Simply not the best do.
How to Handle "Never Ask Once again"?
I am working with Fragment, which required READ_EXTERNAL_STORAGE permission.
override fun onViewCreated(view: View, savedInstanceState: Parcel?) { super.onViewCreated(view, savedInstanceState) when { isReadPermissionsGranted() -> { /** * Permissions has been Granted */ getDirectories() } isPermissionDeniedBefore() -> { /** * User has denied before, explicate why we need the permission and inquire once more */ updateUIForDeniedPermissions() checkIfPermissionIsGrantedNow() } else -> { /** * Need to ask For Permissions, Commencement Time */ checkIfPermissionIsGrantedNow() /** * If user selects, "Dont Enquire Again" it will never ask once more! so but update the UI for Denied Permissions */ updateUIForDeniedPermissions() } } } The other functions are fiddling.
// Is Read Write Permissions Granted fun isReadWritePermissionGranted(context: Context): Boolean { return (ContextCompat.checkSelfPermission( context as Activeness, 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 Activity, PermissionsUtils.READ_EXTERNAL_STORAGE_PERMISSIONS) } ~ Answered on 2019-05-06 ten:14:59
