Xamarin Forms v2.3.5.233-pre1 Incompatibility

[ghost]

Hello!

I really love how this control helps in creating a pull to refreshlayout on a scrollview Unfortunately, the recent Xamarin.Forms pre1 release killed this package

Here's my android stacktrace:

Only fix is not to update xamarin forms to the v2.3.5.233-pre1 release

Thank you so much for checking it out!

[BenDevelopment]

Has anyone found a solution or a workaround?

[leeanpeng]

Is there any update for this issue?

[ericbrunner]

Have the same with Xamarin.Forms v.2.3.5.256-pre6. I posted my stacktrace here on Gist.

[ericbrunner]

I filed a Xf bug: https://bugzilla.xamarin.com/show_bug.cgi?id=57921

[roycornelissen]

Yep, ran into this too today. Would be interested to learn what the root cause is.

[ericbrunner]

I got that information from Xamarin Team Team (jimmy.garrido@xamarin.com):

This appears related to the deprecation of IVisualElementRenderer.ViewGroup in Android[1]. VisualElementTracker now accesses View instead of ViewGroup[2] and since PullToRefreshLayoutRenderer[3] has not implemented it, it throws a Java.Lang.AbstractMethodError.

The PullToRefreshLayout component will need to be updated to 2.3.5 and implement IVisualElementRenderer.View.

[1] https://releases.xamarin.com/pre-release-xamarin-forms-2-3-5-256-pre6/ [2] https://github.com/xamarin/Xamarin.Forms/blob/2.3.5/Xamarin.Forms.Platform.Android/VisualElementTracker.cs#L36 [3] https://github.com/jamesmontemagno/Xamarin.Forms-PullToRefreshLayout/blob/master/PullToRefresh/PullToRefresh.Droid/PullToRefreshLayoutRenderer.cs

[jamesmontemagno]

Makes some sense, I will look into it,

[ericbrunner]

@jamesmontemagno Great. Thanks!

[Troto]

Also had this issue just now, thanks for getting onto it!

[jamesmontemagno]

Fixed in 2.0 alpha, required 2.3.5-pre6

[ericbrunner]

Can confirm that 2.0.0-alpha10 works when in .NET Standard library, Version=1.4 and all xplat projects XF SDK 2.3.5.256-pre6 is installed.

[BenDevelopment]

Works for me too, thanks @jamesmontemagno (but I figured out that your beta version is older than your alpha, should not it be the opposite?).

[jamesmontemagno]

I think beta goes before alpha in their order. I removed the beta though, so should be better now . :)

[KennyDizi]

thanks so much @jamesmontemagno
