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
