Request runtime permissions from v4.Fragment and have callback go to Fragment?

I'm having a weird issue that is causing a conflict. I had to switch to native Fragments to fix it, but there are bugs with that.

My original problem: I have a navigation drawer setup with v4 Fragments. To ask for permission in one of my Fragments I call ActivityCompat.requestPermissions(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION, 1); The prompt shows up just fine, but when I accept or deny the permission, nothing happens. The callback onRequestPermissionsResult() is never called. Instead it gets called in the Activity that my Fragments are attached to. Useless to me, I need the callback to work in the Fragment.

With this in mind I was told that I need to use FragmentCompat, but that only works with native Fragments (v13+), so I changed navigation drawer to work from native Fragments instead of the v4 support library Fragments. However, because I'm using AppCompatActivity, certain things do not work, like addToBackStack() and going back to a previous fragment.

Long story short, does anyone know how I can use the v4.Fragment and still call for permission in the Fragment and get the callback to be in the Fragment? I feel like this is a bug in Android that hasn't been addressed but I'm not 100%.

Let me know if you need to see my code, it's just the standard methods that you need for runtime permissions, I would like to work with v4 Fragments though which doesn't work from my understanding.

Solution 1:

Adding this to the parent activity works for me:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    List<Fragment> fragments = getSupportFragmentManager().getFragments();
    if (fragments != null) {
        for (Fragment fragment : fragments) {
            fragment.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }
}

Solution 2:

If you need to get the permissionResult in fragment v4 make sure you use

Fragment.requestPermission(String[], int);

instead of

AppCompat.requestPermission(Activity, String[], int)
