To my knowledge you can't open your app when you slide open your device, but you can use the sliding feature in your app if you want.
The name of the View (Android speak for a UI widget) is a
SlidingDrawer.
You use the View by adding code to the
DrawerOpen and
DrawerClose events.
private SlidingDrawer _slidingDrawer;
_slidingDrawer = Activity.FindViewById<SlidingDrawer>(Resource.Id.SlidingDrawer);
_slidingDrawer.DrawerOpen += (o, e) => { //add your code here}
_slidingDrawer.DrawerClose += (o, e) => { //add your code here}
