Automatically clear users cache on app update in android

Question

Is there any method in the android API (ideally for 2.3.6 and onwards) that clears the users cache if they download a new version of an app? Looking around there doesn't seem to be any mention of one - or am I off the ball completely and the cache is emptied when a new version is installed?

If nothing else, store a file with your android:versionCode in the cache, and check it on startup, wiping out your own cache if needed - @CommonsWare
