By returning to the tablet operating system I assume you want to invoke
another launcher...
you'll have to either invoke one that you know or ask what are the
launchers available when there is more than one.
You can query what are the launchers available by doing this:
IList<ResolveInfo> resolveList = PackageManager.QueryIntentActivities( new
Intent( Intent.ActionMain ).AddCategory( Intent.CategoryHome ),
(int)PackageInfoFlags.MatchDefaultOnly );
To invoke one of the launchers...
ResolveInfo resolve = resolveList[ ev.Which ];
Intent launcherIntent = new Intent();
launcherIntent.SetClassName(
resolve.ActivityInfo.PackageName, resolve.ActivityInfo.Name );
launcherIntent.AddCategory( Intent.CategoryLauncher );
StartActivity( launcherIntent );
Hope that helps...
