How to connect to Password protected SQLite DB with OrmLite?
OrmLiteSqliteOpenHelper has a constructor which takes a password so change you super call to
super(context, DATABASE_NAME, null, DATABASE_VERSION, (File)null, "DB password goes here");
I would take the call to copyFromAssets(context) out of the DatabaseHelper constructor and call it before DatabaseHelper gets created i.e. first thing when the app starts up
