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

The hardware key is the answer here. I'd be careful about generalising the DRY principle to UIs. There are plenty of cases where you need to hammer, hammer, hammer the same point to the user repeatedly via headings, body text, colours and images.

Users dont "read" UIs the way you read a novel. They scan read.
