Best way to restart TimerTask in Service

i would like to restart my TimerTask in my Service when i changed the refresh time in the config Activity.

The config Activity changes the public static long UPDATE_INTERVAL

Have you some ideas for me?

public void onStart(Intent intent, int startId) {

    // init the service here
    try {
        if (prefs.getStr开发者_JS百科ing("oauth_token_secret", null) != null) {
            _startService();
        }
        } catch (Exception e) {
            Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
        }

}

private void _startService() {

    timer.scheduleAtFixedRate(
         new TimerTask() {
        public void run() {

            //doing things

        }
         }, 0, UPDATE_INTERVAL);

}

Thanks so far. Stefan

Not sure what you mean by "The config Activity changes the public static long UPDATE_INTERVAL", but you can update the interval timing in your run code and it will take effect the next time the TimerTask is run. Or if your Activity is in a seperate class you can create a setter for UPDATE_INTERVAL and when an action is triggered in the Activity you set the timing interval that way.
