Intents with Qt and Android

Phataas

I am making an Android app and using Intents are very common. I have struggled a lot trying to get this to work.

I need an example and/or good explanation on how to do this. As far as I have seen there exists no proper documentation/example on how to do this.

I have run the AndroidExtras/Notifier example and written some additional code as shown below.

I have several questions:

QtActivity I assume is the activity responsibly for the GUI showing on my Android device?
Shall I pass my intent to QtActivity? If yes, how?
How can one use startActivityForResult() and get the result in onActivityResult() like I have tried below?
Is it possible to write code in QtActivity and call code directly from QtActivity? So I could implement this in QtActivity direcly.

@package org.qtproject.example.notification;

import android.app.Notification;
import android.app.NotificationManager;
import android.content.Context;

import android.bluetooth.BluetoothAdapter;
import android.content.Intent;

public class NotificationClient extends org.qtproject.qt5.android.bindings.QtActivity
{
//Bluetooth
private static BluetoothAdapter bluetoothAdapter;
private static final int ENABLE_BLUETOOTH_REQUEST = 1;

private static NotificationManager m_notificationManager;
private static Notification.Builder m_builder;
private static NotificationClient m_instance;

public NotificationClient()
{
    m_instance = this;
}

public void notify(String s)
{
    if (m_notificationManager == null) {
        m_notificationManager = (NotificationManager)m_instance.getSystemService(Context.NOTIFICATION_SERVICE);
        m_builder = new Notification.Builder(m_instance);
        m_builder.setSmallIcon(R.drawable.icon);
        m_builder.setContentTitle("A message from Qt!");
    }

    m_builder.setContentText(s);
    m_notificationManager.notify(1, m_builder.build());
}


public void connect()
{
    bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
    if(bluetoothAdapter == null)
    {
        notify("Bluetooth Adapter not found or supported");
        return;
    }

    if(!bluetoothAdapter.isEnabled())
    {
        Intent enableBluetoothIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
        startActivityForResult(enableBluetoothIntent, ENABLE_BLUETOOTH_REQUEST);
    }
}

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    notify("onActivityResult yay!");

    if(requestCode == 1)
    {
        if(resultCode == RESULT_OK)
        {
            //User accepted and bluetooth enabled
                notify("User accepted to enable bluetooth");
        }
        else if(resultCode == RESULT_CANCELED)
        {
            //User declined or bluetooth enable error
                notify("User declined to enable bluetooth");
        }
    }
}

Most of the troubles was solved reading "here":http://blog.qt.digia.com/blog/2013/12/12/implementing-in-app-purchase-on-android/. And some fixing in my manifest file.
