启动Intent Xamarin.Android后返回主应用程序

Question

I have an android app I am developing on Visual Studio Xamarin.Android In my app I create a .pdf file and launch any .pdf apps using an intent. Code Below...

Android.Net.Uri uri = Android.Net.Uri.FromFile(file);
            Intent intent = new Intent(Intent.ActionView);
            intent.SetDataAndType(uri, application);
            intent.SetFlags(ActivityFlags.TaskOnHome | ActivityFlags.NewTask );
            StartActivity(intent);

My question is: When I click the back button on the application I opened using the intent, it goes to the android home screen. How do I make it go back to the application it was launched from?

使用StartActivityForResult和OnActivityResult http://developer.android.com/training/basics/intents/result.html
