Answer 1

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);

For the reference, I have obtained the answer from this link https://www.coderzheaven.com/2016/10/12/onrequestpermissionsresult-not-called-on-fragments/
