How to make user must allow certain permission to continue using apps

I am developing an apps where permission to write internal storage is crucial. When I am requesting permission for api >23, there is an option to never show the request permission dialog again. I wanted to disable this because if the user choose to deny and check never show the request dialog again, then the user will have to personally go to settings and clear the apps reference himself, which I want to avoid. I also want to keep requesting for permission if the user choose deny, but resulting in error java.lang.ArrayIndexOutOfBoundsException in grantResults[0].
To summarize my problem:
1. how to disable the "never show again check"
2. my error's fix
here's my code in requesting permission again if the user choose deny:
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch (requestCode) {
case PERMISSION_WRITE_EXTERNAL_STORAGE:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Update();
} else {
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, PERMISSION_WRITE_EXTERNAL_STORAGE);
}
break;
}
}

You can't stop the user from permanently denying the permission. When the user does an action that requires the permission, and the permission is denied, you can flash a message - a Toast or a Snackbar, for example.

try this my friend
String permission = Manifest.permission.WRITE_EXTERNAL_STORAGE;
int grant = ContextCompat.checkSelfPermission(this, permission);
if (grant != PackageManager.PERMISSION_GRANTED) {
String[] permission_list = new String[1];
permission_list[0] = permission;
ActivityCompat.requestPermissions(this, permission_list, 1);
}
#Override
public void onRequestPermissionsResult ( int requestCode, #NonNull String[] permissions,
#NonNull int[] grantResults){
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 1) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(AccountClass.this, "permission granted", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(AccountClass.this, "permission not granted", Toast.LENGTH_SHORT).show();
}
}
}

How to give persiomission com.sec.android.provider.badge.permission.READ or WRITE in android 6.0

I am trying to show badge on app icon when notification came from server.
I am getting this exception:
Caused by: java.lang.SecurityException: Permission Denial: opening provider com.sec.android.provider.badge.BadgeProvider from ProcessRecord{ab1124 10588:com.rehq.app/u0a175} (pid=10588, uid=10175) requires com.sec.android.provider.badge.permission.READ or com.sec.android.provider.badge.permission.WRITE

Since Android 6.0 you need to request permissions at Runtime before you need them.
The example below is for the WRITE permission (I guess you'd like to add a badge to the app icon and normally you don't need the READ permission for this - if you need it you can request it just like the WRITE permission)
First add your permissions in the Manifest:
<uses-permission android:name="com.sec.android.provider.badge.permission.WRITE"/>
Then you can check if they are granted at Runtime like this:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
&& ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_SETTINGS) != PackageManager.PERMISSION_GRANTED) {
//permissions not granted -> request them
requestPermissions(new String[] {Manifest.permission.WRITE_SETTINGS}, YOUR_REQUEST_CODE);
} else {
//permissions are granted - do your stuff here :)
}
The result will be available in onRequestPermissionResult:
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions,
#NonNull int[] grantResults) {
if (requestCode == YOUR_REQUEST_CODE) {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_SETTINGS) == PackageManager.PERMISSION_GRANTED) {
//permissions granted -> do your stuff ;-)
}
//Permission not granted -> react to it!
return;
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
You can read more about it in the official docs

How to grant android.permission.RECORD_AUDIO permissions to android shell user?

I build some command line tool with android NDK and execute it in /data/local/tmp. Now it prompts me “requires android.permission.RECORD_AUDIO”. It's usually in AndroidManifest.xml for java application, but how to grant it to android shell user?
Source code like:
sp<AudioRecord> rec = new AudioRecord(AUDIO_SOURCE_MIC, 44100, AUDIO_FORMAT_PCM_16_BIT, AUDIO_CHANNEL_IN_MONO);
Logcat:
I/AudioFlinger( 3772): AudioFlinger's thread 0xf0e838c0 ready to run
W/ServiceManager( 3772): Permission failure:android.permission.RECORD_AUDIO from uid=2000 pid=-1
E/ ( 3772): Request requires android.permission.RECORD_AUDIO
E/AudioFlinger( 3772): openRecord() permission denied: recording not allowed
E/AudioRecord(14132): AudioFlinger could not create record track, status: -1
--------- beginning of crash

After Lollipop, Android platform is using real time permissions. If your app running in Marshmallow and after versions, you should grant your permissions in Activity.
Before request permissions:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) ==
PackageManager.PERMISSION_GRANTED) {
// put your code for Version>=Marshmallow
} else {
if (shouldShowRequestPermissionRationale(Manifest.permission.RECORD_AUDIO)) {
Toast.makeText(this,
"App required access to audio", Toast.LENGTH_SHORT).show();
}
requestPermissions(new String[]{Manifest.permission.RECORD_AUDIO
}, REQUEST_CAMERA_PERMISSION_RESULT);
}
} else {
// put your code for Version < Marshmallow
}
After this, overraide this method and put your code:
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == REQUEST_AUDIO_PERMISSION_RESULT) {
if (grantResults[0] != PackageManager.PERMISSION_GRANTED) {
Toast.makeText(getApplicationContext(),
"Application will not have audio on record", Toast.LENGTH_SHORT).show();
}
}
}

private void requestRecordAudioPermission() {
String requiredPermission = Manifest.permission.RECORD_AUDIO;
// If the user previously denied this permission then show a message explaining why
// this permission is needed
if (getActivity().checkCallingOrSelfPermission(requiredPermission) == PackageManager.PERMISSION_GRANTED) {
} else {
Toast.makeText(getActivity(), "This app needs to record audio through the microphone....", Toast.LENGTH_SHORT).show();
requestPermissions(new String[]{requiredPermission}, 101);
}
}
#Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
if (requestCode == 101 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// This method is called when the permissions are given
}
}
Execute this code if you have device with marshmallow or upper OS

How to determine whether user has accepted or denied a permission in Android?

I have an application which ask for permission from the user to start the device's bluetooth. I want to know whether if the user accepted or denied the permission.
Is there any method to do that.

You must override onRequestPermissionsResult method.
For example, here you check if user granted permision for access to his location:
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 1) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
//Do something here
}
}
}
}
Also, before that when you ask your permission you must determine your requestCode, which will be also sent to this method, when the user will be asked for permission. So it would be something like here:
if (ContextCompat.checkSelfPermission(MapsActivity.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MapsActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
So now, my requestCode is equal to 1(and i am checking that later in my onActivityRestult method.
Hope this helps.

Automatically detect to show allow permission after user deny in the first time asking

I working with anroid app in Android M and need some permission that allow to access CAMERA, RECORD_AUDIO, WRITE_EXTERNAL_STORAGE, ... so I put my permission checking when user open the app in the first time. But if user deny it, how can I detect it automatically that user is using the feature that required permission then ask them again? Or I have to put my condition in every feature that need permission.
I know when we use some feature that required permission but not allowed already it will throw the exception, so do we have any class that handle this task?

I use this logic: Every Activity extends a BaseActivity, in which there is a method that check the permissions everytime the onCreate() is called.
The method that I use is:
public static boolean hasPermissions(Context context, String... permissions) {
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
So, everytime the user launch a new Activity, the application check the permissions and display which permissions are not granted yet.
To manage the result, use onRequestPermissionsResult()
BTW, this logic will ask the user the permission even if the activity's feature doesn't require any permission.
If you want to ask the user the permissions only where the feature that requires a permission, you must check it in every activity

onRequestPermissionsResult you can check particular Permission is granted or not you can call Permission dialog again from there if particular permission not granted for Example
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions,
#NonNull int[] grantResults) {
if (requestCode == REQUEST_CAMERA) {
// BEGIN_INCLUDE(permission_result)
// Received permission result for camera permission.
Log.i(TAG, "Received response for Camera permission request.");
// Check if the only required permission has been granted
if (grantResults.length == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Camera permission has been granted, preview can be displayed
Log.i(TAG, "CAMERA permission has now been granted. Showing preview.");
Snackbar.make(mLayout, R.string.permision_available_camera,
Snackbar.LENGTH_SHORT).show();
} else {
Log.i(TAG, "CAMERA permission was NOT granted.");
// Ask again for permission
}
// END_INCLUDE(permission_result)
} else if (requestCode == REQUEST_CONTACTS) {
Log.i(TAG, "Received response for contact permissions request.");
// We have requested multiple permissions for contacts, so all of them need to be
// checked.
if (PermissionUtil.verifyPermissions(grantResults)) {
// All required permissions have been granted, display contacts fragment.
Snackbar.make(mLayout, R.string.permision_available_contacts,
Snackbar.LENGTH_SHORT)
.show();
} else {
Log.i(TAG, "Contacts permissions were NOT granted.");
// Ask again for permission
}
} else {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
