This just means that response is not a HttpResponseException, but could be any other Exception or none at all (Successful?).

To find out what kind of class it is, you can print the class name in your else-block:

Toast.makeText(mActivity, "reponse is an instance of: " + response.getClass().getSimpleName(), Toast.LENGTH_SHORT).show();

The name should give you a clue already. If it is another exception, it looks like your preceding try-catch is to general and catching away all exceptions. Replace it with a less general one:

try {
    // Your networking code
} catch (HttpResponseException httpResponseException) {
    response = httpResponseException;
}

Now the app should crash when running your code and deliver you the stacktrace with the information what is going wrong.
