Why this thread doesn't work?

Question

I wrote this code to try threads on Android, but it doesn\'t work.

   @Override
   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(save         


        

Answer 1

You're calling t.run() which means you're running all the code in the UI thread without starting a new thread.

You should call t.start() which will instead start a new thread and execute the code in the run method within that new thread.

(I'd also recommend implementing Runnable and then passing the Runnable to a new Thread constructor rather than overriding run, just as a matter of separation of concerns. It won't change the behaviour here, but it's a cleaner way of thinking about it IMO.)
