Jako LogCat powiedział:

07:26:47.051: E/AndroidRuntime(12992): Caused by: java.lang.NullPointerException 09-04 

Jest to NullPointerException. Nie widzę, aby zainicjować swój mImage. Musisz zainicjować go w metodzie onCreate().

Dodaj ten fragment kodu do metody onCreate().

mImage = (ImageView)findViewById(R.id.yourImageViewId);
