Use android Application class run a thread background to post some data to webservice

Question

Could I write a thread in Android the Application class? This thread is running every five minutes to post data to a webservice.

public class MyApplication  extends Application {
@Override
public void onCreate() {
    startUploadGPSTimer();
}

private void startUploadGPSTimer() {
    gpsTimerHandler.postDelayed(runnable, 5* 60 * 1000); // start Timer
}

private Handler gpsTimerHandler = new Handler();

private Runnable runnable = new Runnable() {
    public void run() {
        Map<String, String> params = new HashMap<String, String>();
        params.put("latitude", Global.CUR_LATITUDE);
        params.put("longitude", Global.CUR_LONGITUDE);
        WebServiceObj obj = new WebServiceObj("upload",
                WebServiceMethod.METHOD_UPLOAD_GPS,
                Utilly.getSoapParams(params));
        SoapService service = null;
        SoapObject result = null;
        service = new SoapService(obj.tag);
        result = service.LoadResult(obj);
        Log.i("post webservrce  ", result.toString());
        gpsTimerHandler.postDelayed(this, 5 * 60 * 1000);
    }
};

When my application enter background, this thread like do not running. Because of the data I post in thread Finally input to Database, and I can't find it in db.

Why?

I write some log when do post data to webservice. and found the log be generated randomly. Very strange

Are you sure it is not running? Can't you just log something every N seconds and check if the problem is with Handler. — Dmytro Danylyk, Nov 03 '12 at 13:35
@AnandTiwari I'm sure the db is OK. The db is on web, some other data could find in db... — Ray, Nov 04 '12 at 13:24

Intent photosIntent = new Intent(this, MyService.class);
pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0,photosIntent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, 5*60*1000,5*60*1000, pendingIntent);

In MyService is a Service Class write your stuff in onstart to send request to webservices. This service will call for every 5minutes.

Hope this helps.

Thanks
