Xamarin forms labs: System.NullReferenceException Object reference not set to object instance

Question

After upgrading from Xamarin Forms to version 1.3.1, I get the following error .
Also tried updating Xamarin.Forms.Labs to 1.2.1 pre2 , this also didn't help.

 [MonoDroid] UNHANDLED EXCEPTION: [MonoDroid] System.NullReferenceException: Object reference not set to an instance of an object [MonoDroid] at Xamarin.Forms.Platform.Android.FormsApplicationActivity.OnDestroy () <IL 0x0002d, 0x000d8> [MonoDroid] at Xamarin.Forms.Labs.Droid.XFormsApplicationDroid.OnDestroy () [0x0001f] in c:\Users\rmarinho\Documents\GitHub\Xamarin-Forms-Labs\src\Xamarin.Forms.Labs\Xamarin.Forms.Labs.Droid\XFormsApp.cs:61 [MonoDroid] at Android.App.Activity.n_OnDestroy (intptr,intptr) [0x00009] in /Users/builder/data/lanes/monodroid-mlion-monodroid-4.20-series/ba9bbbdd/source/monodroid/src/Mono.Android/platforms/android-17/src/generated/Android.App.Activity.cs:2524 [MonoDroid] at (wrapper dynamic-method) object.e36a43a7-84b6-4476-8a62-6959a3b43e6a (intptr,intptr) <IL 0x00011, 0x0003b> 

Any help on fixing this error?

Answer 1

I looked at the source code of FormsApplicationActivity , and it looks like you somehow get rid of your object before assigning it a page (or at least this way of rejecting, I think, is possible).

Share your code with us for a more detailed solution, but basically try setting up the main page of the application before uninstalling.
