Error in the cursor when performing a query in sqlite from the assets folder when the application is removed and reinstalled

Question

I have a problem when I query the sqlite database from the assets folder only when I uninstall the application and reinstall it. If it is the first time it is installed the application runs normally without any problem. In the list of errors shows me that the error is in the cursor but I do not understand the reason because when I install the application for the first time does not happen this. When I delete the data from the data folder it returns to normal operation.

Attached code:

    public class MainActivity extends AppCompatActivity {

ButtonRectangle button,button2;
EditText view;
private MyDatabase db;
ListView listView;
FloatingActionButton nuevaB;



@Override
protected void onCreate(Bundle savedInstanceState) {
   setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    listView= (ListView) findViewById(R.id.listView);
    view = (EditText) findViewById(R.id.view);
    db = new MyDatabase(MainActivity.this);
    button2= (ButtonRectangle) findViewById(R.id.button2);
    button= (ButtonRectangle) findViewById(R.id.btnAceptar);

    nuevaB= (FloatingActionButton) findViewById(R.id.floatB);

    File database = getApplicationContext().getDatabasePath(MyDatabase.DBNAME);
    //Si la base de datos no existe

    if(false == database.exists()) {
        db.getReadableDatabase();
        //Copiar db
        if (copyDatabase(this)) {
            Toast.makeText(this, "Base de datos creada", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(this, "Error al crear la base de datos", Toast.LENGTH_SHORT).show();
            return;
        }
    }

The database is in the assets folder and when the installation is run it is verified if it is in the phone. If it finds it does nothing otherwise copy it.
