Xamarin Forms - callback is not called in android and in iPad

[dhruvgohiloo7]

If user clicks cancel button or closes the browser using device's back button in android then callback is not called.
Same occurs with the iPad, when user clicks outside the browser it will close the browser without calling the callback.
Note : It works fine with the iPhone

One more issue with android is, browser gets closed when user resumes the app from background.

@dhruvgohiloo7 It works 9 months ago, I cannot support every Android SDK and policy changes, sorry.
You have to upgrade the sample yourself.
