sk.baka.ambient.views
Class LongOperationExecutor

java.lang.Object
  sk.baka.ambient.views.LongOperationExecutor

All Implemented Interfaces:

DialogInterface.OnCancelListener, Runnable

public final class LongOperationExecutor
extends Object
implements Runnable, DialogInterface.OnCancelListener

Shows the wait-for dialog and runs long running operation in the background. The start() method starts the long running operation in new thread.

Exceptions thrown by the runnable are reported using AmbientApplication.error(Class, boolean, String, Throwable).

The Runnable should periodically check for the interrupted state (using Thread.currentThread().isInterrupted()). If it is interrupted it should finish ASAP. It may do so by throwing an Exception - exceptions are not reported when the process is interrupted.
