Thanks in advance!


You don't use System.out.println() on Android. You use Log.v(), Log.d(), etc.

Documentation here.


This is displayed in the Logcat. You can choose to display Logcat if you go to Windows - Show Views -> Android -> Logcat.


If you want a visual response on the phone, use Toast.

You can use Log.e(),Log.v(),Log.d() for displaying output or exception and you can see that in logcat.


@EboMike is right, anyway, you can see the output in the LogCat view

 Window --> Show View --> LogCat

Assumes, that you have Android's ADT plugin installed.
