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:versionCodein the cache, and check it on startup, wiping out your own cache if needed –@CommonsWare
