问题 I've build a custom android ROM. I've signed my application with platform signature and have added android:sharedUserId="android.uid.system" in the manifest file.

问题 My app requires to access CAMERA and WRITE_EXTERNAL_STORAGE permissions. Once my app loads I want to ask user to allow both of these permissions one after another. I have this code: if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 2); } if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) !=

问题 Before targetting android O code below worked perfectly.

I was getting scolded for my app because every time a permission request would popup, the overlays popup would be shown

问题 I check for the required permissions on my Log In screen. The dialog shows asking for the 4 permissions I need. All good, but when the dialog appears, the background becomes black and my app closes (doesn't crash, just closes). When I'm done with choosing the permissions I open the app again and it continues running from where it stopped. How can I make the app continue running while the permissions dialog is shown? I use a class which checks for permissions and call it in the Log In activity
