Android sqlite query return cursor with 0 results

I am calling AsyncTask passing in a method to be executed to make sure the method returns a name string NAME

from a specific identifier. when calling a database query / raw query on doInBackground, it returns a cursor with null results even when trying with the query SELECT * FROM TABLE

when TABLE has 8 records. What is the problem? Is the request out of sync? if so how should I code it to prevent such problems?

EDIT

...
final TextView tv = (TextView)findViewById(R.id.textView);

dao.retrieveMovieByIdAsync(1, new AsyncTaskCaller() {
    @Override
    public void execute(Movie result) {
        tv.setText(result.get_Name());
    }});
...

private class AsyncRetieveQuery extends AsyncTask<Method, Void, Movie>
{
    private Object args;
    private AsyncTaskCaller signal;

    public AsyncRetieveQuery(Object args, AsyncTaskCaller signal) {
        this.args = args;
        this.signal = signal;
    }

    @Override
    protected Movie doInBackground(Method... params) {
        params[0].setAccessible(true);
        try {
            return (Movie) params[0].invoke(DBUtils.this, new Object[] {args});
        } catch (Exception e) {
            return null;
        }
    }

    @Override
    protected void onPostExecute(Movie result) {
        signal.execute(result);
        super.onPostExecute(result);
    }
}
...
public void retrieveMovieByIdAsync(int id, AsyncTaskCaller resultMethod)
{
    try {
        new AsyncRetieveQuery(id,resultMethod).execute(DBUtils.class.getDeclaredMethod("retrieveMovieById", int.class));
    } catch (NoSuchMethodException e) {}
}
...
private Movie retrieveMovieById(int id)
{
    Cursor cursor = database.rawQuery("SELECT * FROM " + SQLiteHelper.TABLE_MOVIES_NAME + " WHERE _Id = ?", new String[] {String.valueOf(id)});

      

        
        
        
      

    

The debugger always shows it with zero results
