track application stack change event wp8.1

Question

I am new to WP8 development, I need to know is there a way to trace the application stack change (check if application comes from deactive (dormant) to active (tombstoned) state) event in wp8.1 same as android gives us. If it is how we can trace that particular event and before opening the app change stack with my own app. Actually I am planing to create an applock application same as android have.

Thanks and Regards

It is possible to 'track' the state of your app - not the application stack. However it also depends on the platform you are targeting:

for WP8.0 and WP8.1 Silverlight - you have Activated and Deactivated events. For more help - read App activation and deactivation for Windows Phone 8 - there are more cases to be considered.
for WP8.1 WinRT - you have Suspending and Resuming events - for more help read Application lifecycle (Windows Runtime apps) - there are also more cases to be considered here.

I doubt you will be able to exchange the opened app.

hey @Romasz, thanks for your quick response. actually i need an event to trace which app on top of the stack or which app is currently active. I need it in outside environment of the app not inside the environment of the app. Actually i am trying to create an applock application same as android have. – Oct 08 '14 at 13:13
@InderjeetSinghSethi AFAIK With official API it's not possible. – Romasz Oct 08 '14 at 13:16
