[TIMOB-15829] Android: Calling Ti.UI.Android.ProgressIndicator.hide() twice crashes app on next show()

    Ti.UI.backgroundColor = 'white';

    var win = Ti.UI.createWindow({
      backgroundColor: 'blue'
    });

    var button = Ti.UI.createButton({
      title: 'Show Progress Dialog'
    });

    var progressIndicator = Ti.UI.Android.createProgressIndicator({
      message: 'Loading...',
      location: Ti.UI.Android.PROGRESS_INDICATOR_STATUS_BAR,
      type: Ti.UI.Android.PROGRESS_INDICATOR_DETERMINANT,
      cancelable: true,
      min: 0,
      max: 10
    });

    button.addEventListener('click', function (e) {
      progressIndicator.show();
      var value = 0;
      setInterval(function(){
        if (value > 10) {
            return;
        }
        progressIndicator.value = value;
        value ++;
      }, 200);
      // do some work that takes 3 seconds
      // ie. replace the following setTimeout block with your code
      setTimeout(function(){
        progressIndicator.hide();
        progressIndicator.hide();
      }, 3000);
    });

    win.add(button);
    win.open();
