Answer 1

Basically you need to start the network request in a background thread. Once the network operation is complete you should notify the main/UI thread to change the waiting screen into the results.

To notify the main thread have a look at the link below and search for invokeLater:

Word of advice: Don't spawn to many threads at once on mobile devices. Usually they have a really low maximum number of threads.

Do one thing.... At the listner event of button write this.

UiApplication.getUiApplication().invokeLater(new Runnable(){ public void run(){ Status.show("Please Wait....",b,3600); message.setText(test(theFile)); } });
