How to open 'App Permissions' page in Settings programmatically in Android?

Here is a method to open Settings > Permissions for your application:

java

public static void openPermissionSettings(Activity activity) {
  Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS, 
      Uri.parse("package:" + activity.getPackageName()));
  intent.addCategory(Intent.CATEGORY_DEFAULT);
  intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  activity.startActivity(intent);
}

You should consider using this when your permission is denied and shouldShowRequestPermissionRationale(Activity activity, String permission) returns true.
