How do I close game browser on Android device?

Hi,

I'm developing a game for my client. The game is browser based but loads in an Android app. So, once the game is over or if the user taps on 'X', the browser should be closed and the user will be redirected to the app. In order to achieve this I have used Browser->close function but it didn't work, so I created a script function Android.End(runtime), it didn't work either.

Any suggestions on how to achieve this?

Thanks in advance,

Sudeep
