I have an application for which I am planning to release both a free and a paid version. I found that this will require the two versions of the application to each have different package names.
When a user upgrades from the free version to the paid version, the paid version needs to be able to access the database built by the free version. I am trying to understand the best way to make sure that upgrade does not disrupt the user's data. I have read that the AndroidManifest file setting for shared user id should allow both applications to access the same data. I don't need the applications to both be running simultaneously, as I expect the user will uninstall the free version after upgrading to the paid version. However I need to make sure that if possible the user's data is not lost and is still accessible and usable by the paid version of the application. I have read about a problem with the shared user id where uninstalling one application will cause the other shared application to stop working because its permissions get deleted, (see details at http://code.google.com/p/android/issues/detail?id=2773 ) Apparently this issue is fixed in doughnut, but since all the currently deployed android phones do not have doughnut yet, this still seems like a significant problem. In addition to the database information, I would also like to preserve the user's default shared preferences settings after the upgrade. However the default shared preference settings are not as critical as the data in the database. I would greatly appreciate any input from others that have dealt with this issue, regarding the best way to make sure that users upgrading to a paid version won't lose all the data they put into the free version of the application. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
