Why is there no cancel button in Android's progress dialogs?

Question

I\'m facing a head-scratching moment similar to what this person (from Jan 2008) experienced when I realized that there is no cancel button in Android\'s progress dialog or spin

Answer 1

I can't speak for other apps, but in mine anything that might cause the UI thread to wait is executed in a seperate thread. The most I'll do is show a small progress spinner in the titlebar to let the user know something is going on in the background.
