Android AsyncTask에서 부울 값을 반환하는 방법은 무엇입니까?

AsyncConnectTask task = new AsyncConnectTask(SiteManager.this,
            _address, _username, _password, _port);
task.execute();

public interface MyInterface {
    public void myMethod(boolean result);
}

public class AsyncConnectTask extends AsyncTask<Void, Void, Boolean> {

    private MyInterface mListener;

    public AsyncConnectTask(Context context, String address, String user,
        String pass, int port, MyInterface mListener) {
        // ...
        this.mListener  = mListener;
    }

    @Override
    protected Boolean doInBackground(Void... params) {
        // ...
        return result;
   }

    @Override
    protected void onPostExecute(Boolean result) {
        if (mListener != null) 
            mListener.myMethod(result);
    }
}

AsyncConnectTask task = new AsyncConnectTask(SiteManager.this,
            _address, _username, _password, _port,  new MyInterface() {
    @Override
    public void myMethod(boolean result) {
        if (result == true) {
            // Connection successful
        } else {
            // Connection failed
        } 
    }
});

task.execute();
