Hi, is there any way to check whether an application is currently running at the foreground?

I heard some developers mentioned about stack? But which class in Android API should I use?

When your app is "on top" Android framework will call 'onStart()', when you app "go in background" you'll receive 'onPause()'

Thanks. I am more of trying to know whether an application (other than mine) is running in foreground. Any hint on this? Thanks.

Once I too needed this, but my finding was that there is no way to check the stack for your app. I needed this because when my app goes to background, clicking on the my app icon on the home screen starts it afresh rather bringing my app in background to foreground.
