Question

need a service that will run in background and it will awake after 30-120 seconds and find the location where the device is,then send the location to the data center and go to sleep.Again 30-120 seconds later service awake and determine location and go to sleep. I can start and stop the service manually.But i need to start(between 30 to 120 sec) and stop the service automatically.I can not remain the service live cause it will drain the battery.

So,My question is how can i start and stop the service automatically?

Thanks advance for any suggestion.

My code is

public class Service extends Activity {
   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button start = (Button)findViewById(R.id.startButton);
        Button stop = (Button)findViewById(R.id.stopButton);

        start.setOnClickListener(startListener);
        stop.setOnClickListener(stopListener);

   }

private OnClickListener startListener = new OnClickListener() {
public void onClick(View v){
    startService(new Intent(Service.this,SimpleService.class));
}               

};

private OnClickListener stopListener = new OnClickListener() {
    public void onClick(View v){
        stopService(new Intent(Service.this,SimpleService.class));
    }               
};
}

You can user AlarmManager Class for your requirement. Create an alarm that will awake a Service on Specific Timer Interval ( in your case 30-120 seconds ). while awaking destroy the previous running service by calling it onDestroy() method.
