onDestructiveMigration() don't work for me
fe...@gmail.com
I need do stuff before .fallbackToDestructiveMigration() is called like saving data and after call this method restore this datas
Description
Version used: 1.1.0
Devices/Android versions reproduced on: All
When we are working with Room database that contains predefined data, we can populate these predefined data when first creation of the database via Callback#onCreate(SupportSQLiteDatabase). If that project decided to fallback to destructive migration, all the predefined data will be delete during the migration and there is no way to notify if that happens so we can insert those predefined data.
My suggestion would be adding a new callback method e.g. onDestructiveMigrate(SupportSQLiteDatabase). Then notify the callback once migrated by destruction.
