I’m trying to maintain databases synchronized between a Webservice and Android app.
The code below is working, but I encounter some problems:

Every time I go to main page of App a new infinite process is started.
The process never ends

Can anyone explain how to start and stop this process as I wish?
I want this process to run every 5 minutes, but only once and when the app is open.

public void onCreate(Bundle savedInstanceState) {   
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final Handler handler = new Handler();
    final Runnable r = new Runnable() {
        public void run() {
            // DO WORK
            Mantenimiento();
            // Call function.
            handler.postDelayed(this, 1000000);
        }
    };
    r.run();
}
