Upgrading from android-database-sqlcipher to sqlcipher-android

[developernotes]

Hi @FrozenPyrozen,

@FrozenPyrozen

we storing user in SQLiteDatabase which imported from import net.sqlcipher.database.SQLiteDatabase; and we updating the sqlcipher to 4.5.4 and installing newer build, by default do sqlcipher library do some changes for example how db was encrypted/decrypted and old data becomes unavailable or it should work by default with prev version created, encrypted db without any changes/logouts?

You previously mentioned using SQLCipher for Android 3.5.7. If you are upgrading to SQLCipher for Android 4.5.4, you will need to review the upgrade recommendations as SQLCipher 4 will not open a SQLCipher 3 database by default, there are several approaches to address this.

@FrozenPyrozen

What are the possible triggers/events that could lead to clearing user data from db etc?

SQLCipher for Android uses the DatabaseErrorHandler (similar to android.database.sqlite.DatabaseErrorHandler) using the default implementation which will delete the file on corruption. This is consistent with the android.database.sqlite package. You can override this behavior by providing your own implementation for a DatabaseErrorHandler via constructor argument to a SQLiteOpenHelper subclass, or the static openDatabase or openOrCreateDatabase on the SQLiteDatabase class.
