问题 Both of the below works fine on the emulator (2.3.3), but on a real device (Nexus S with 4.1.2) no image is shown for the thumbnail. I will also try to run it on an Android 4 Emulator . If I set a default android:src for the ImageView , it is not shown anymore then. This makes me think that it is replaced, but the ImageView is empty. public class MainActivity extends Activity { ImageView img; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
