Hi,

I am reading the chapter about work with sensors, and I tried to run the app Speedometer but seems like it is not working,

I tried to change the time of update of this part of code as well,

PHP Code:


			
 Timer updateTimer = new Timer("velocityUpdate");

      updateTimer.scheduleAtFixedRate(new TimerTask() {

        public void run() {

          updateGUI();

        }

      }, 0, 10);

here is the thing: I am triying to use this example to know when my cellphone is falling down or , when I move my cellphone quickly with my hands,

any idea?

best,

I think I am learning why is not working, my first idea is because mytextview is not been updating, so I check the code with a toast and:

PHP Code:


			
Context context = getApplicationContext();

      

      Toast toast = Toast.makeText(context, String.valueOf(currentAcceleration), );

      toast.show();

and is working, the first values are between 9.8-9.9 and I thought that was because is the gravity force, I think will be very interesting if you can explain a little bit more about:

calibration
and why the example is not working 100%, cuold be a configuration of the phone?

best,
