I\'m switching from SQLiteOpenHelper to SQLiteAssetHelper so i can use an existing DB s

Answer 1

Do not initialize Activity instance variables that require a Context in their declarations, as the Context will be null. Initialize dbTools inside an appropriate lifecycle method like onCreate:

DbHelper dbTools;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...
    dbTools = new DbHelper(this);
}
