Android and checking for new data per hour

Im creating a news-like app and I want to know is is possible to start app (ex : 1 time per 1h) to check if new data is available. You know what im talking about, I think. App should start from nowhere, check and finish().

Is this possible? I know that widgets can do it but normal activity or something like this?

Please, help. Damian.

Yes, It is possible to use an "Alarm Service" in android, and use it to perform some work, at specific intervals.

Here is the link to Alarm Service documentation: http://developer.android.com/reference/android/app/AlarmManager.html

Here is a sample code which uses Alarm Service

    /**
     * Method to start background service for server refresh and other tasks.
    */
    public void startMyService()
    {
        //Start Service service to handle data refresh
        Intent serviceIntent = new Intent(this, MyCommunicationService.class);

        //Schedule additional service calls using alarm manager.
        AlarmManager alarmManager = (AlarmManager) this.getSystemService(ALARM_SERVICE);
        PendingIntent pi = PendingIntent.getService(this, 0, serviceIntent, 0);

        //Retrieve time interval from settings (a good practice to let users set the interval).
        MyPreferenceManager prefManager = new MyPreferenceManager(this);        
        alarmManager.cancel(pi);
        alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), prefManager.getDataRefreshTime()*1000  , pi);

    }

Note that we are multiplying with 1000, because the parameter for setRepeating() method is in milliseconds.
