onRequestPermissionsResult not being called in fragment if defined in both fragment and activity

Edited answer to cover broader issues

I think you are confusing the method for fragment and activity. Had a similar issue my project last month. Please check if you have finally the following:

1. In AppCompatActivity use the method ActivityCompat.requestpermissions
2. In v4 support fragment you should use requestpermissions
3. Catch is if you call AppcompatActivity.requestpermissions in your fragment then callback will come to activity and not fragment
4. Make sure to call super.onRequestPermissionsResult from the activity's onRequestPermissionsResult.

See if it helps .

I requested location permission from a fragment and in the fragment, I needed to change this:

            ActivityCompat.requestPermissions(getActivity(), new String[]{
                Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, LOCATION_REQ_CODE);

to this:

            requestPermissions(new String[]{
                Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, LOCATION_REQ_CODE);

then the onRequestPermissionsResult was called in the fragment.

This is a common mistake that people make when coding for marshmallow.

When in AppCompatActivity, you should use ActivityCompat.requestPermissions; When in android.support.v4.app.Fragment, you should use simply requestPermissions (this is an instance method of android.support.v4.app.Fragment) If you call ActivityCompat.requestPermissions in a fragment, the onRequestPermissionsResult callback is called on the activity and not the fragment.

requestPermissions(permissions, PERMISSIONS_CODE);

If you are calling this code from a fragment it has it’s own requestPermissions method.

So basic concept is, If you are in an Activity, then call

ActivityCompat.requestPermissions(this,
                            new String[]{Manifest.permission.CAMERA},
                            MY_PERMISSIONS_REQUEST_CAMERA);

and if in a Fragment, just call

requestPermissions(new String[]{Manifest.permission.CAMERA},
                            MY_PERMISSIONS_REQUEST_CAMERA);
