Issue after upgrading v4 Support Library
FRMember ✭
Hi all !
I have an issue after upgrading my v4 Support Library Package From v21 to v22.
My app crashes when trying to use a Custom Renderer inheriting from ListViewRenderer. It worked perfectly before upgrade.
I tried to upgrade my SDKs through the Android SDK Manager but it doesn't solve my problem.
Thanks a lot !
Here is the exception :

@MauroCasu Before I could even try downgrading the V4 pkg, the V22.1.1.1 has arrived and it worked. Now there were a host of Xamarin updates have come and they are yet to work well with my setup.

In fact the issue is still here with the Standard ListView Renderer :
I have exactly the same issue. A project using Master/Detail crashes after the update with the same error of missing method StartCreateInstance:
System.Diagnostics.Debugger.Mono_UnhandledException_internal () in
System.Diagnostics.Debugger.Mono_UnhandledException (ex={System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.MissingMethodException: Method not found: 'Android.Runtime.JNIEnv.StartCreateInstance'.
at Xamarin.Forms.Platform.Android.MasterDetailRenderer..ctor ()
The project worked perfectly before the upgrade.
Thanks,
Mauro
@EmmanuelGonzalez, @MauroCasu can you run a Build, Clean operation, then Rebuild All to see if that fixes the issue?
I've recently seen some of the updates to the codebase require a complete fresh build of your application.
Hi Mitch,
I have tried to clean all and rebuild but same issue. The only way I have found to fix it, is to downgrade Xamarin.Android.Support.V4 from version 22.1.1 to ver 22.0.0.
I am using Xamarin Studio 5.8.3 on a Mac.
Thanks,
Mauro
The same error here, how to fix it? anybody from Xamarin already know about this?
@TheRealJasonSmith @CraigDunn
I've the same error with the latest Grid Demo Sample from DevExpress (for their latest version 15.1.3 of DevExpress Grid for Xamarin Forms; version 15.1.2 worked).
Could not find a solution for this until now ..
Same error here. An App with a Master-Detail-Page crashes on
LoadApplicationwith that error.Same issue here. LoadApplication crashes with mscorlib issues.
I'm also seeing the issue with the MasterDetailPage
Same issue here
Same issue as well here. With MasterDetailPage.
Same issue with me when using MasterDetailPage. LoadApplication is throwing:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.MissingMethodException: Method not found: 'Android.Runtime.JNIEnv.StartCreateInstance'.

@MauroCasu How do you downgrade to v22.0.0? On Mac I don't find any option in the 'Add Packages' window.
@ShantimohanElchuri To downgrade a package on Xamarin Studio for Mac, you can just add the same package again with the keyword "version:" at the end, like this:
Xamarin.Android.Support.V4 version:
It will show to you all the available versions for this package and then, if you add it again (with a previous version), it will be replaced.
Consider that some packages have dependencies and you are sometimes required to downgrade other packages as well.
Mauro
@ShantimohanElchuri Sorry in my previous post I forgot a star () at the end of the keyword "version:", the right example is this:
Xamarin.Android.Support.V4 version:
Mauro
@ShantimohanElchuri Looking at my previous posts, in my browser the star does not appear...
anyway, if you don't see it, just add a star after the colon at the end of the version keyword.

I'm getting the same issue at LoadApplication(...) with X.Forms v1.4.2.6355 and X.Android.Support.v4 v22.0.0.0
Error dump and system config attached.
I have tried the new version of the package (22.1.1.1) and now the issue seems correctly fixed.
Thanks,
Mauro
@MauroCasu Before I could even try downgrading the V4 pkg, the V22.1.1.1 has arrived and it worked. Now there were a host of Xamarin updates have come and they are yet to work well with my setup.
I just had the same issue with the latest nugets of both xamarin forms and Android.Support.v4. However after many hours of head scratching I tried to upgrade xamarins visual studio plugin. It weirdly worked after that?!?!?
