Answer
I suggest that you to try with findViewById(android.R.id.content).
This is what did the trick for me:
Snackbar.make(findViewById(android.R.id.content), resp.getMessage(), Snackbar.LENGTH_LONG).show();
android.R.id.content will give you the root element of the view (for more information on that, please check Android: What is android.R.id.content used for?).
