How do I most easily delete Android application data upon upgrade/update?
<p>So, I have found a bug in a specific sdk that causes it to fail on some Android phones after re-installing a new version of an app which uses the sdk (via adb install -r, and presumably when a user gets an update that has been pushed to the Android market). Is there any way to force an application's data to automatically be cleared upon update of the app? I realize there are different ways that data could be stored, but I just need to essentially simulate an invocation of the "Clear Data" button that'd you find when browsing to the application in the "Manage Applications" section of the Settings (i.e. I just want all data gone). </p>

<p>I am an Android noob and am doing minimal Java coding on this project, so I am basically looking for the simplest solution here. I suppose I could settle on storing a "currentVersion" to disk and then checking it upon launch every time to see if the <em>real</em> current version matches the version that was written to disk on the last launch. Is that the only real way to do this?  If so, what's the simplest way to do so?</p>

<p>Thanks!</p>
