Wie LogCat sagte:

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

Es NullPointerException ist. Ich sehe nicht, dass Sie Ihre mImage initialisieren. Sie müssen es in onCreate() Methode initialisieren.

Fügen Sie dieses Code-Snippet zu onCreate() Methode hinzu.

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