Having the same issue. Not linking the SDK assemblies fixes the issue but I ended up with a huge APK. I'm also adding a stacktrace from a debug build (you can reproduce it in debug by not using the shared runtime + linking SDK assemblies).

Also, reproducible with XF 4.0 preview.

Simply rolling back to XF 3.4.0.1029999 solves the problem.

Can I link the SDKs but avoid linking this specific SDKs/namespaces? Would that solve the problem? I am assuming these are the namespaces I should avoid linking "Syncfusion.ListView.XForms"
"Syncfusion.ListView.XForms.Control.Helpers"
"Syncfusion.ListView.XForms.Helpers"
"Syncfusion.SfPullToRefresh.XForms"
"Com.Syncfusion.Sfpulltorefresh"
"Syncfusion.SfPullToRefresh"
"Syncfusion.SfPullToRefresh.Android"
"Syncfusion.SfPullToRefresh.iOS"

Edit:
I looked at this further and the linker needs assembly name not namespaces.
"Syncfusion.SfListView.XForms.dll"
"Syncfusion.SfPullToRefresh.XForms.dll"
"Syncfusion.SfPullToRefresh.Android.dll"
"Syncfusion.SfPullToRefresh.iOS.dll"
According to
https://www.fuget.org/packages/Syncfusion.Xamarin.SfListView
https://www.fuget.org/packages/Syncfusion.Xamarin.SfPullToRefresh
https://www.fuget.org/packages/Syncfusion.Xamarin.SfPullToRefresh.Android
https://www.fuget.org/packages/Syncfusion.Xamarin.SfPullToRefresh.IOS

Edit Again:I tried not linking those assemblies but it still crashed. I am not going to try with this any more and just downgrade to 3.4.

Similar issue here.(works with Xam.forms 3.4 but not in latest 3.5.0.129452 stable)
See attached error logs.
xamform_runtime_error_Android.txt

@AmrAlSayed0 Syncfusion's assemblies are not SDK assemblies. So I don't think that linking SDK assemblies + the list you provided does anything special. That would work if you were to link user assemblies too.

Based on the stack trace, I believe it's some change in the Android support library, something related to SwipeRefreshLayout?

Same issue on Android here. iOS is working fine.

Please try with 3.5.0.169047. Does this still occur? Thanks!

Still crashes in release mode. Tested by cloning the project above and updating the Xamarin and Syncfusion libraries.

Hi Team,
I have a crash in both debug and release mode also. But if i keep linking option to Don't Link then i could able run my app without crash with xamarin forms 3.5.
But i could run if downgrade to Xamarin.Forms 3.4 without crash in both release and debug mode.
Can you please have a look at this case in debug mode also.

Still having issues. Any updates on this?

Any estimate when this will be fixed?

Is that linker issue? I have tested in debug mode enabling full linking and it worked fine but if I use full linking in release mode, it crashes. That's bit confusing

I reached out to SyncFusion about this one. I haven't been able to narrow down the cause for the crash yet.

From version 3.4 to 3.5 of forms the base class on the ScrollViewRenderer changed from ScrollView to NestedScrollView so SF had to put out a patch for this which for some reason isn't playing nice with 3.5

I recompiled 3.5 and changed the ScrollViewRenderer base class back to ScrollView and when I did that the older version of SF worked fine so there's something with the newest 54 release of SF that doesn't seem to play nicely with XF 3.5

@samhouts confirming this as a blocker for 3.5 and anyone using Syncfusion list view. What is our ETA for a Xam Forms update to resolve

We're not sure this is something for Xamarin.Forms to fix. It may be something that SyncFusion needs to resolve.

@samhouts From Syncfusion This issue only occurs after Xamarin.Forms update version 3.5 update with linker enabled. As we mentioned, issue occurs because of the Xamarin framework update and we logged issue report (5288) for the same. It can be resolved by setting Linking option as None as we share before.

For now, you can use the earlier Xamarin.Forms (Version 3.4 and earlier) updates to avoid this crashing issue. We are following up with the reported frame work issue and let you know once it is resolved.

We appreciate your patience and please use the earlier Xamarin.Forms updates (3.4 and earlier) until then.

[email protected] is the contact. Would appreciate if you two could connect/resolve so we can update. We are on day 15 of not being able to release.

@caseyniemann We've been in contact with SyncFusion about this matter, and we are working together to resolve it. Thanks

Hi Team,
As of now, most of our customers are working by linking as None and this cannot be permanent solution for this crash in release mode. Can you please provide the fix with updated version asap.
We haven't received any of your notifications regarding this issue.

Can you please confirm the issue and share update regarding?

@GnanaPriyaNamasivayam I emailed Marissa Keller Outten and Christian Grossmann last Thursday and yesterday. That's usually who I contacted whenever I had questions. Should I only ever email support or is there someone else internally I should be emailing to expedite these things?

Can you please set my SF license up with a Source License so that I can compile and debug against SF please? shneuvil at Microsoft dot com is my email address that my current license is against

@samhouts @GnanaPriyaNamasivayam Please connect and resolve, and use the @ sign so you both see this

@samhouts, Could you please confirm, is there any possibilities of providing an immediate fix for this linker issue in the upcoming Xamarin update?

We've marked this with our highest priority, and there is communication between SyncFusion and Xamarin engineers. We're working on it. Thanks.

@samhouts @GnanaPriyaNamasivayam does any of this get resolved in the 3.6 Xamarin update?

@caseyniemann As of right now, we're still seeing the same issues with the latest version of SyncFusion and XF 3.6. It is possible that SyncFusion needs to rebuild against 3.6 in order to resolve this issue. Perhaps @GnanaPriyaNamasivayam or @Nijamudeen-Mohamed can try this and confirm. Otherwise, @PureWeen is scheduled to discuss this directly with SyncFusion on Monday, and we'll have an update then. Thank you for your patience.

With XF 3.6 I get compilation errors with FFImage so cannot say :/

@xperseguers Yep, we're aware of that. https://github.com/luberda-molinet/FFImageLoading/issues/1154#issuecomment-470589841

any Progress or ETA for this issue please?

@samhouts @GnanaPriyaNamasivayam We need this resolved, 23 days

24 and XF 3.6 is here, I wonder if Syncfusion will do testing

We're narrowing down on an issue with the Android team and working on a way to mitigate the issue for now with SF. Once a solution is in motion I'll post an update.

@samhouts @GnanaPriyaNamasivayam For those expecting 3.6 and the latest of Synfusion to work...it does not. From Syncfusion: The reported issue exists in Xamarin v3.6 also and still this issue not fixed by Xamarin team Xamarin team?

I hope this will be fixed soon. My Android app is now over 100 megabytes in the Play store. Much larger because I disabled the linker.

If you want to see the sausage making you can track the progress here: https://github.com/xamarin/Xamarin.Forms/projects/32

This particular fix is part of Sprint 150 which is scheduled to complete on 3/29. Unfortunately, there's no way to tell if an actual production-ready fix will be pushed by then.

This is a serious regression, imho it should hot-fixed immediately.
The first step should be to identify the commit in XF3.5 responsible for this regression. Has it been done already ?

Still no assignee... what's going on ??

At this point we have a plan in place that will involve a release from both sides. There's still some additional testing that needs to be done just to ensure we've dotted and crossed all the things

• Syncfusion is going to push out a release which will make this work for 3.1, 3.2, 3.3, 3.6
• We are working on a hot fix for 3.4 and 3.5 that will make it work for those versions

@PureWeen @GnanaPriyaNamasivayam Is there any timeline for these fixes?

@PureWeen @GnanaPriyaNamasivayam Is there any timeline for these fixes?

@Giorgi - Already promised by Xamarin team that this fix will be done within their current sprint and provided timeline on March 29, 2019.
https://github.com/xamarin/Xamarin.Forms/issues/5288#issuecomment-473300702

In their forum thread Syncfusion is still saying is a Xamarin thing, they don't seem to have a release estimate for their change to support 3.6?
https://www.syncfusion.com/forums/142489/compatibility-with-xamarin-forms-3-5

As @PureWeen said in his comment, this is a coordinated release with SyncFusion. Xamarin is releasing service releases to fix compatibility for 3.4 and 3.5. SyncFusion is releasing a new version that will fix compatibility with 3.5 and 3.6. Hopefully, both Xamarin releases will be available next week. Although we cannot speak to SyncFusion's release schedule, we are aware that this is a high priority for them as well.

There were a lot of variables that went into this issue that made it difficult to determine a course of action that is best for our customers. This will be resolved soon, and we have measures in place to prevent such issues from occuring again. Thank you for your patience!

I tried to ignore the assembly while linking by adding the following to the ignore list but it didn't work.
Syncfusion.SfListView.XForms
I have 2 question:

• Why do Syncfusion's assemblies which is a third party plugin is being linked when i select Link SDK assemblies only?
• Can we ignore all the assemblies under a namespace ?

@ali-h2010 because syncfusion tools like sflistview, it doesnt use xamarin forms listview, it is probably using datagrid with custom virtualization pretending to be listview. So xamarin made some breaking changes on datagrid, i presume and broke all the custom tools of Syncfusion. Syncfusion is actually quite ahead of xamarin regarding the tools, for example, drag and drop feature is still not exist in xamarin tools and it is hard to remove dependency of sflistview or sfdatagrid from our apps.

1 month I face this issue and that I wait for a fix.
I've been telling to my boss that a release will come soon.

I made the mistake to migrate to XF 3.5 without testing in release mode on both platform. My bad, shame on me. Since, I've writtent too much code that relies on XF 3.5 (mostly bindableLayout). I need to make a release and it may be cheaper to remove the SfListView and use the Telerik one instead.
I hope you can give us a fix before the end of next week otherwise, I'll have to migrate to Telerik's ListView which works fine (even if I prefer the SfListView).

Link assemblies set to none didn't fix it neither.
I wish you luck !

Me too, I'm thinking we can actually replace (in our use case) SF List with a custom implementation based on XF 4 CollectionView but will require time

This works just fine with the release they did this morning. Did you forget to upgrade? At least with XF 3.6 which is the current stable release.

1 month I face this issue and that I wait for a fix.
I've been telling to my boss that a release will come soon.

I made the mistake to migrate to XF 3.5 without testing in release mode on both platform. My bad, shame on me. Since, I've writtent too much code that relies on XF 3.5 (mostly bindableLayout). I need to make a release and it may be cheaper to remove the SfListView and use the Telerik one instead.
I hope you can give us a fix before the end of next week otherwise, I'll have to migrate to Telerik's ListView which works fine (even if I prefer the SfListView).

Link assemblies set to none didn't fix it neither.
I wish you luck !

My Android with XF 3.5 app and SF .53 works and is in the Play Store. Using these settings:

This works just fine with the release they did this morning. Did you forget to upgrade? At least with XF 3.6 which is the current stable release.

So they already did a major version update which seems to address the issue, cool we will try it thanks for letting us know about the update

The question is: why a major version release, while it should have been a simple hot-fix.
Communication around this issue has been such a disaster...
I hope it will work without any new regression, or this time I'm done with SF.

We apologize for the frustration that this issue has caused. We are committed to preventing such issues in the future, and we're taking steps to prevent regressing third-party controls, such as SyncFusion and Telerik, among others. We value them, and we value our community!

We released 3.4.0.1039999 and 3.5.0.274416 on 2019-03-26 . SyncFusion confirmed with us that these versions no longer crash when tested with their latest version, but I don't know exactly what the SyncFusion version number is.

If you are still experiencing this issue with Xamarin.Forms 3.6 or the versions I've mentioned above, I encourage you to reach out to SyncFusion about the matter (https://www.syncfusion.com/forums/142489/compatibility-with-xamarin-forms-3-5), since I'm not sure they are monitoring this issue any longer. I'm confident that SyncFusion is working hard to get this matter resolved for their customers, and if there is anything else that Xamarin.Forms needs to do, we'll make sure that it's a priority.

Thank you!

Ok, this morning, I updated to the version of 26 march (the release of today wasn't released yet or nuget cache problem I guess because as I said : I tried with Linking assemblies to none).
I'm glad to confirm it doesn't show a white screen anymore. Thanks !!
I didn't want to use the Telerik ListView as IMHO the SfListView is better.

Tried with Linker mode to Link SDK assemblies only and it doesn't work with Xamarin.forms 3.6.0.264807 and Syncfusion 17.1.0.38 https://help.syncfusion.com/xamarin/release-notes/v17.1.0.38?type=all

same issue. i still am getting a crash and annoying license alerts too.
Thanks SF, you gave it to us for free but you don't have to rub it in our faces.

@samhouts @PureWeen doesn't work with Xamarin.forms 3.6.0.264807 and Syncfusion 17.1.0.38. It's clear from above that the communication between Xamarin and Syncfusion is broken....and has been broken for more than a month and half. Get connected today and get this resolved

Same for me. The issue is still here with XF 3.6.0.264807 and SF 17.1.0.38.
It's still not clear to me though if the issue is in XF or SF.
@samhouts @PureWeen Could you please clarify and fix urgently?

We've reached out to SyncFusion to find out what version they expect the fix to be in. Someone will report back here with that information.

Thank you for your patience!

Wow I was about to update, thanks for letting us know, in their release notes they don't mention the compatibility issue, they seem to reference other 3.5 issues there https://help.syncfusion.com/xamarin/release-notes/v17.1.0.38?type=all
So Xamarin did their job fixing 3.5 but yes 3.6 and above should be fixed by SF side as mentioned before

Me too, I'm thinking we can actually replace (in our use case) SF List with a custom implementation based on XF 4 CollectionView but will require time

yes it is possible to create everything of sflistview or sfdatagrid using CollectionView. even if you do custom virtualization, possible with bindable stacklayout or datagrid. this is what syncfusion is doing even though you gave me thumbs down but i am telling you the truth. they arent using ListView of xamarin as inheritance. only thing hard to do is drag and drop feature on sflistview i will be missing

Man I believe you, just thumbed down because then is hard to remove dependency :) which is the ugly thing we all come across

We regret for the inconvenience caused.

We have fixed the android linker issue in Sflistview. Currently it could be in testing state, checking on various possible scenarios and list view feature testing. We will complete these testing and update the patch in our upcoming weekly nuget. It could be expected on April 9, 2019. We appreciate your patience until then.

@EmilAlipiev
This solution has drag and drop and advance lists
https://github.com/roubachof/Sharpnado.Presentation.Forms

The question is, will it crash in release mode.
Also, i invested heavily on Syncfusion's listview so it will take some time to rewrite the code.

As per the earlier discussion we confirm that fix will be included on our upcoming weekly Nuget scheduled date April 9, 2019 without any further delay. Meanwhile, if you require SfListView Custom Nugets/Assemblies before the weekly Nuget release, please create the support ticket using following link .

We are glad to announce that our latest weekly NuGet package update version 17.1.0.40 has been rolled out with the reported issue that “Native crash in release mode with SfListView and Xamarin Forms 3.5 and above” and is available for download (nuget.org).

The above problem is not related to the topic of this github issue but I figured that I will post it in here anwyays, as I was looking to fix this issue and ran into another...Also it's very fresh and SF people might still be monitoring this thread. The above happens with the Xamarin.Forms 3.5.0.169047 version.

I'm attaching a repro sample. It's an updated SfListView grouping sample that you can find on SF sites. I've tested it on VS 2019 (v 16.0.0).

SfListViewGrouping.zip

EDIT: Confirmed that it doesn't happen in Xamarin.Forms 3.5.0.274416 version

We have checked the reported query in the given sample. We would like to inform you that reported crash occurs only in the particular Xamarin version 3.5.0.169047. Is there any specific purpose for using that version because this crash is fixed in all latest versions released after 3.5.0.169047. We recommend you to update the Xamarin Forms version to the latest version to resolve this reported issue.

New version (17.1.0.40) works for me with Xamarin.Forms 3.6.0.293080.
Now I am able to build my iOS and Android Apps when Linking SDK Assemblies in Release mode without seeing any native crashes.
Thanks.

I just wanted to chime in that 17.1.0.40 crashes in Xamarin Forms pre-release 4.. I had updated a project to pre-release 4 to test a feature in Prism pre-release (which requires xam 4), and there were still issues with 17.1.0.40. I downgraded everything to Xamarin Forms 3.6.x and the original issue with linking, which is the topic of this thread) is resolved. Just wanted to give a heads up in case someone updates to pre-release 4..

@SharbelWired can you post your stack trace?

@SharbelWired,

We would like to inform you that Syncfusion Xamarin.Forms components are only compatible with Xamarin Forms stable version. We have mentioned regarding this in our documentation. Please refer our documentation form below link for your reference.

UG Documentation Link : https://help.syncfusion.com/xamarin/introduction/compatibility-road-map

@samhouts , One of our client installed the latest version of Xamarin.Forms v3.6.0.344457 but still he is facing the issue in his application ref Forum.

As per the below commented suggestion, it should resolve in this version.
https://github.com/xamarin/Xamarin.Forms/issues/5288#issuecomment-478075117

Can you please check the issue in this version and revert us asap?

I am having the same disaster now

SfListView Version 17.2.035

Xamarin Forms version 4.1.0.581479

@jrahma looks like a bug should be opened with Syncfusion, not Xamarin.
We just started experiencing an OOM crash on Android only in release mode:
Xamarin 3.6.539721
SfListView 17.2.0.35

We are removing Sflistview

I did not update to XF 4.1, I'm still on 4.0. However, I updated Visual studio to latest 16.2 and I've got a crash on linking with SfListView too. Maybe something linked with new AOT introduced in this version ?

@DineshBabuYadav One can try to skip linking this particular assembly to fix the prob I guess ?

@DineshBabuYadav it's not with SfListView only but with other controls as well. I use SfRototator in my MainPage and now my app is crashing after upgrading to Visual Studio 16.2 and Syncfusion 17.2.036

don't you think a week is a very long time to fix a serious problem which caused a disaster crashing apps?

For example, my client is a semi government organization and others might have business and eCommerce app so that means their whole eOperation on mobile will be stopped for a week?

Appreciate if this will be fixed immediately

@jrahma it should not affect your end user as you might have released an earlier version of your app with earlier Syncfusion and XF versions. I don't understand your point. This should only affect your local build or staging ones. Unless you published a new version w/o QA test before release but that's another prob 😀.

Sf team has to investigate the prob. Apply a fix and test it. Its ok that it takes a few days

that's the problem, my earlier app had a problem and I was waiting for the fix which came with a disaster

and the app works fine on all devices and emulators but this problem happens only when installing the app from Google Play

This is what I am getting in Google Play Console:

Hi Everyone,

As promised, we will let you know once the release has been rolled out i.e., July 30, 2019.

@jrahma , we are checking with SfRotator team and will let you know the details asap.

@DineshBabuYadav One can try to skip linking this particular assembly to fix the prob I guess ?

yes, until then you can skip this linking option to resolve the issue at the application itself.

hat's the problem, my earlier app had a problem and I was waiting for the fix which came with a disaster

and the app works fine on all devices and emulators but this problem happens only when installing the app from Google Play

what is the difference between testing in release mode and installing from google play? you should be getting this when you run on release also, dont you?
It is strange that I am not having any problem with full linking using xf 4.1.0.581479 and sflistview 17.1.0.52. it is maybe because i am doing my release builds on VS4Mac 2019, Could it be that it is only problem on VS 2019 Windows?

@EmilAlipiev Well it seems only linked with VS2019 latest. I did not update Syncfusion packages nor Xamarin Forms one, only VS. 16.2.0 introduces a new feat for AOT and bundled assemblies, I guess the error is from here.

@vincentcastagna those settings were exist in earlier versions vs 2019 also, at least on enterprise version. Are you talking about community version? those who have problem can they confirm that it is community version of VS?

Same problem with VS 16.2.0 and VS for Mac 8.2. Both of them are Enterprise license.

Try vs mac 8.3 preview. It works fine for me. I will check vs 16.2 later.

@EmilAlipiev yep I'm on the community version

Reporting in. VS2019 16.1.6 / XF 4.1.0.618606 / SfListView 17.2.0.35
Setting Linking to none solves the problem which only appears in release mode.

VS MAC 8.2 (1105)
XF Stable 4.1.0.618606
SF 17.2.0.36

I received crash
[MonoDroid] System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object

+1

downgrade to 17.1.0.52, it works fine for me in release mode. I tried on VS mac and VS windows latest updates.
