Titanium.Accelerometer

Adds an accelerometer update event listener, and displays the x, y and z axis in the window when the device is moved. On Android, the accelerometer is switched off and on when the application is paused and resumed.

var win = Ti.UI.createWindow({
  backgroundColor: 'white',
  exitOnClose:true,
  layout: 'vertical'
});

opts = {
  color:'black',
  font:{fontSize:20},
  text:'-',
  top:20, left:10,
  width:300
};
var labelTimestamp = Ti.UI.createLabel(opts);
win.add(labelTimestamp);
var labelx = Ti.UI.createLabel(opts);
win.add(labelx);
var labely = Ti.UI.createLabel(opts);
win.add(labely);
var labelz = Ti.UI.createLabel(opts);
win.add(labelz);
win.open();

var accelerometerCallback = function(e) {
  labelTimestamp.text = 'timestamp: ' + e.timestamp;
  labelx.text = 'x: ' + e.x;
  labely.text = 'y: ' + e.y;
  labelz.text = 'z: ' + e.z;
};

if (Ti.Platform.model === 'Simulator' || Ti.Platform.model.indexOf('sdk') !== -1 ) {
  alert('Accelerometer does not work on a virtual device');
} else {
  Ti.Accelerometer.addEventListener('update', accelerometerCallback);
  if (Ti.Platform.name === 'android') {
    win.addEventListener("open", function(e) {
      win.activity.addEventListener("pause", function() {
        Ti.API.info("removing accelerometer callback on pause");
        Ti.Accelerometer.removeEventListener('update', accelerometerCallback);
      });
      win.activity.addEventListener("resume", function() {
        Ti.API.info("adding accelerometer callback on resume");
        Ti.Accelerometer.addEventListener('update', accelerometerCallback);
      });
    });
