Make it possible to preserve internal app data on uninstall #769

Since Android 10 it is possible to preserve the internal app data on uninstall (see screenshot attached): https://developer.android.com/reference/android/R.attr#hasFragileUserData https://developer.android.com/guide/topics/manifest/application-element#fragileuserdata

This would be useful, as the wallet data can be preserved across uninstallations on the same device. monerjuo_preserve

Cool. Haven't tested yet but approve otherwise. Since there is now internal data being used that could alleviate some concerns about losing wallet data.

is this tested across an uninstall/reinstall as the keys used to encrypt the wallet files (probably) get deleted rendering the files useless without the crazypass?
