Migration?

[riccione]

Hi.

I was trying to update the database. I did this by increasing the number of version inside AppDatabase. In this case I got an error that I must setup migrations. I tried to do it in this way

Room.databaseBuilder(context.getApplicationContext(),
AppDatabase.class, "database.db")
.fallbackToDestructiveMigration()
.openHelperFactory(new AssetSQLiteOpenHelperFactory())
.build();

And in result I get an empty database?! How can I solve this? Where is my mistake?

Actually I got it. There is not important to provide any migration. But how to pass to the AssetSQLiteOpenHelperFactory information that the database was updated inside the asset folder?

How to do that? I'm stuck in the same problem.
