Crash when tapping on Android notification

[radioactiveman]

🐛 Bug Report

Tapping notifications (e.g. push notifications) causes an app crash on Android when the app is started.
It is also no bug in Xamarin.Forms because the crash does not occur with a plain Xamarin.Forms solution, without MvvmCross.

Expected behavior

Tapping the notification starts the app without a crash.

Current behavior

Tapping the notification causes the exception below in MainActivity::OnCreate().

System.NotSupportedException: Unable to activate instance of type Xamarin.Forms.Platform.Android.PageRenderer from native handle 0x7fedad6424

Reproduction steps

• Start the app
• Click the button "Show notification"
• Tap on the Android notification

Sample project: App1.zip

Configuration

Version: 6.2.2

Platform:

• 📱 iOS
• 🤖 Android
• 🏁 WPF
• 🌎 UWP
• 🍎 MacOS
• 📺 tvOS
• 🐒 Xamarin.Forms

I have finally found a fix. For the activity the launch mode has to be set:

[Activity(..., LaunchMode = LaunchMode.SingleTop, ...)]
