We originally wrote our app in titanium, but because titanium + android is so bad we made the devision to write V2 of the app in Java. App now works great but when the app updates from market, it crashes unless the app data is removed or V1 is uninstalled first.
How can I fix this issue? Is there a way of telling the market to fully remove app first before installing update?
Found out it is not possible. It appears you cannot choose to clear app data on an update 🙁
