I think this error appears because you didn’t close your database. Always close your sqlitehelper class

EDITED:

You have to implement like this in your class which is extending SQLiteOpenHelper class:

@Override
public synchronized void close() {
    if(db != null){
        db.close();
    super.close();
    }   
}
