Android - Forcing ANR for testing purpose

Question

Why i can\'t force Android ANR with this code? No log messages or pop up. The application is just launched lazily.

[UPDATE]

I can\'t get it even sleeping a V

Answer 1

Try using:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    int a=0;
    while(true) {
        a++;
    }       
}

Your code probably didn't work because it got setup too early, and the Activity probably wasn't fully initialized and created yet. With the above code, launch the activity and touch/swipe on the screen and wait for the ANR dialog to popup.
