setInterval or Another Alternative?

After setInterval crashed my app a few times, I went to the forums and noticed that there is currently a bug with this function. Is there any ETA on a fix, or some other alternative I can use. Basically, I am just trying to swap the BackgroundImage of a View every second or so.

setInterval does work, I guess I was just calling it incorrectly. For any who are interested, here is an example of how it works:
```
var green = false;

function changeLEDColor () {
    if (green) {
        ledView.backgroundImage = 'images/greenLED.png';
        green = false;
    }
    else {
        ledView.backgroundImage = 'images/redLED.png';
        green = true;
    }
}

setInterval(changeLEDColor,1000);
```

- Thanks in my app I was declaring setInterval like this which was causing the app to crash:
  
  setInterval(changeLEDColor(),1000);
  
  I am surprised removing the brackets stops the app crashing ?!

- It's normal.
  When you pass changeLEDColor(), you give to setInterval the result of your function (that's to say: nothing here).
  And then, setInterval will use this result as a function –> crash.
  
  But, if you pass changeLEDColor, you pass a reference to your function. And thus, setInterval can use it as a function.
  
  That's it.

- Thanks for that!
  I don't suppose you know what setInterval doesn't fire on android ?
