Make Android service using qt 5.7

[AmrCoder]

I am using qt 5.7 for android after I create templates and go to AndroidManifest.xml I found this line

<!-- For adding service(s) please check: https://wiki.qt.io/AndroidServices -->

I go to the website and got the code to add the service to my android app and add it after the line above and make a test but it not works I don't see my app in the running service on my android phone
so what I do wrong or what I should do to make android service to my application
Thanks in dvance

There are some limit when make Android service on Qt

• the activities & service(s) must run on a different process.
• it is not possible (yet (hopefully)) to debug the services in QtCreator. This feature will take some time to implement it, therefore I’ll not hold my breath for it, check QTCREATORBUG-16886
  For more detail, I suggest you check post of KDAB blog, i think it will help you

@kd_wala First Thanks for your reply
i try the website you post and follow it and i chose to use my service on demand i add the java class in the link
and change the packages and edit it to use it in my project when the app start and i press the button to start service that have this code

void MainWindow::on_pushButton_2_clicked()
{
    //org.qtproject.example
    QAndroidJniObject::callStaticMethod<void>("org/qtproject/example/MyService",
                                                  "startMyService",
                                                  "(Landroid/content/Context;)V",
                                                  QtAndroid::androidActivity().object());
    qDebug() << "Is valid" << QAndroidJniObject::isClassAvailable("org/qtproject/example/MyService"); // return true
}

i got

unfortunately services has stopped

so what should i do now i follow the steps and iam sure that there is no wrong in it ?

this what I have reached in my android manifest .xml

	     <service android:process=":qt" android:name="org.qtproject.example.MyService">
        <!-- android:process=":qt" is needed to force the service to run on a separate process than the Activity -->

            <!-- Application arguments -->
            
            <!-- Application arguments -->

            <!-- If you are using the same application (.so file) for activity and also for service, then you
                 need to use *android.app.arguments* to pass some arguments to your service in order to know which
                 one is which.

As i know, Qt & android run in separate thread, so, if your config is correct, i think problem is you should call function start service on Android UI thread, you can check function QtAndroid::runOnAndroidThread of module androidextras
