About Task(Runnable)

[frodoking]

1.this task cannot canceled?
2.about this code :

At BaseMovieRunnable ...{
// ...
@OverRide
public void onPreTraktCall() {
getEventBus().post(createLoadingProgressEvent(true));
}

// ...
@OverRide
public void onFinished() {
getEventBus().post(createLoadingProgressEvent(false));
}
// ...
}
If I have more than one request in multiple pages, use same Event at same time, it's really work?
