Question activity closes when i try to change db

[stripreviewer]

I'm trying to change the science.db, keeping the same rules of the db structure required by the question activity but I can't understand why my application continues to crash.

It crashes also if I change the english.db in science.db, simply renaming it, why?

To do so created an excel sheet and then converted it into a csv file. After that I used DB Browser for SQLite and I tried to import the table into the table "science" of "science.db". The app crashed... why

Check hashsumm your database, because change database name return another database. Check table name in database classes.
