I want to store some data that should remain also after application uninstall and to be accessible by a new version of this application. Share preferences/files are not a solution as they are removed when program is uninstalled, also writing to internal memory is not a solution (also removed with uninstall). Writing to external public folders I see that is not removed but this would require an external SD Card and don't want to be constrained by this. I don't know about using the SQLite database, how it works? It could be a solution for what I want ? Or any other solutions would be appreciated.
The databases made by your app will be stored in /data/data/your.package.name/databases/ and will be deleted on uninstallation of the app.
So, that's not a solution. I think the only way would be using the SD-card.
