Печалька :(
As a final note, if your database exists previous to setting the shared user id in the manifest, you will need to uninstall/reinstall the apps on a physical device, lest you will lock yourself out of your database (sqlite error 14). The emulator, on the other hand, might prove to be more forgiving. Bottom line, if your apps are published on the Android market, setting a shared user id in an afterthought will not work.
Не годится этот вариант, нужен доступ к уже существующей базе. Переуставливать ничего нельзя.
