Ffimageloading: Init exception with latest Xamarin.Forms 3.4 / 3.6

[stesvis]

Description

I updated the Xamarin.Forms NuGet Package to the latest version and now I get an exception on OnCreate in Android (iOS untested so far).

Actual Behavior

Unhandled Exception:

System.TypeLoadException: VTable setup of type FFImageLoading.Forms.Platform.CachedImageFastRenderer failed

Basic Information

• Version with issue: 2.4.3.840 with XF v3.4.0.1008975
• Last known good version: 2.4.3.840 with XF v3.3.0.967583
• Platform: Android, not sure about iOS

Reproduction Link / Code

In MainActivity, in OnCreate(), it happens on this line:
FFImageLoading.Forms.Platform.CachedImageRenderer.Init(enableFastRenderer: true);

Same here

[daniel-luberda]

Did you try to delete all bin/obj folders, clean solution & then rebuild? I just tested and it's working fine (I even updated repo packages too)

[japero]

Deleted from those projects that uses these packages. No affect to me. I even restarted Vs17 but error remained.

[daniel-luberda]

Could you write more info of your dev environment? Xamarin.Android version, VS version, etc?

[IoTFier]

I was getting FATAL error using XF 3.4 on Xamarin.Forms App running on Android platform
Downgrading to XF 3.3 removed that error but images from resources folders are showing with lowest resolution (Android 8.0). My usage of FFImageloading is in the context of using it while building UI with Gorilla player and Gorilla SDK. (I have masked my app package details …)

VS Community 15.9.1

[IoTFier]

Now back to XF v3.2 but not happy about that choice when I want to use FFImageloading while making use of XF 3.4 and next ones ...

[japero]

VS17 Enterprise 15.8.9, Works on Xamarin.Forms 3.3.0.967583
If I update to latest Xamarin.Forms 3.4...... error is happening.
I reverted Xamarin update because no need for new features yet

[IoTFier]

@daniel-luberda - with the new rhythm for Xamarin.Forms release since 3.2 .. It might be worthwhile to have regression plugged in to validate compatibility and report any issues into Xamarin.Forms team directly .. ? thoughts ?

In the mean time, please help in updating FFImageLoading compatible with XF 3.3, 3.4 that will also help in picking up the images with resolution corresponding to the underlying device resolution.

Thanks

[daniel-luberda]

Could you try 2.4.4.858-pre.nupkg?

[IoTFier]

did it pass your regression under XF 3.3 and 3.4; including image issue I mentioned above ?
just asking because it takes a lot of time to upgrade , compile , deploy and test .. and revert in case...

Sorry but thanks a lot.

[daniel-luberda]

I only updated packages & recompiled as I can't reproduce that issue on my projects (even sample project from FFImageLoading is working fine). I'm on beta channel (Mac)

help in picking up the images with resolution corresponding to the underlying device resolution.

Could you explain it in details and create a separate issue for it?

[IoTFier]

@daniel-luberda .. the FATAL error is gone but images problem I mentioned as in XF 3.3 still exist.
On Android 8.0, while previewing my UI using Gorilla player - FFImageloading package is picking up images from the lowest resolution … that problem doesn't exist in FFImageloading stable version + XF 3.2. Please help.

[IoTFier]

Did you compile it against XF 3.4 or XF 3.3 ?

[daniel-luberda]

3.4

.. the FATAL error is gone but images problem I mentioned as in XF 3.3 still exist.
On Android 8.0, while previewing my UI using Gorilla player - FFImageloading package is picking up images from the lowest resolution … that problem doesn't exist in FFImageloading stable version + XF 3.2. Please help.

I don't use Gorilla Player but I don't think it's FFImageLoading related issue. You can review code responsible for retrieving assets here: https://github.com/luberda-molinet/FFImageLoading/tree/master/source/FFImageLoading.Droid/DataResolvers

and you'll see that it supports device size specific assets.

[IoTFier]

Well.. I am just wondering how come that's working with XF 3.2 and stable version of FFImageloading ?

[alexshikov]

@daniel-luberda 2.4.4.858-pre fixes the issue.

[IoTFier]

@daniel-luberda - will you be releasing a stable version today ?

[mackayn]

FFImageLoading 2.4.4.859
Visual Studio: 17.9
Android Support: 27.0.2.1
Forms: 3.3.0/3.4.0

Deleted all obj&bin and cleared nuget cache.

[mackayn]

@daniel-luberda

Worth noting I'm seeing this in Forms 3.3.0 as well, it only occurs though after updating to VS 17.9, in 15.8 everything was okay. Have you tested with 17.9?

[daniel-luberda]

@mackayn Hi, I tested it on Mac VS 7.7 but I don't see anything related to FFImageLoading in the given stack trace. Are you sure it's FFImageLoading? Maybe it's other lib?

I didn't make any fix for XF 3.4 - I only rebuild it with XF packages updates. Maybe VS is caching those files somewhere?

@IoTFier Stable is released already

[mackayn]

@daniel-luberda

It's definitely FFImageLoading that fails

[NiknakSi]

I had the same TypeLoadException on Mac as well, until I upgraded the XF package from 3.4.0-pre1 to stable. As @daniel-luberda says it's probably the IDE holding onto something. In any case, 2.4.4 definitely works with XF 3.4.0 stable.

[IoTFier]

@daniel-luberda, a BIG THANK for removing FATAL Error.
All good with VS 17.9.1, XF 3.4 except my image resolution issue that I talked about ..

Appreciate your help in making us look good. Many paid vendors struggle to reach this bar and level of understanding to serve their customers.

A big Applaud for your professionalism. Thank you !

[mackayn]

@daniel-luberda

Yah, finally got there, delete all obj & bin, close VS, clear %temp%, re-open VS, clear nuget cache, open solution, restore & rebuild, all good.

Thanks for sorting this so quickly.

[EmilAlipiev]

@daniel-luberda i have cleaned obj, bin, tmp, nuget cache all folders and restart VS2017 but Svg images are either not displayed or displayed badly. it looks there is something terribly breaking with Svg images. i think the problem with this issue https://github.com/luberda-molinet/FFImageLoading/issues/1156

[stesvis]

It seems to be working for me now after updating XF again, and also FFImageLoading!

[JFMG]

I had the same issue when I updated XF to 3.4. I solved it when I also updated FFImageLoading and FFImageLoading.Forms to the newest stable version. In addition, I had to delete bin und obj folders. Now it works.

[ghost]

I think it's not a problem of FFImageLoading, but of how Android 8 works, maybe something works differently than other versions...

Update: I test in Android 7, and also have the error.

[lassana]

I had this issue using latest FFImageLoading and Xamarin.Forms 3.3. I've fixed it by updating X.F to 3.4.

[PostImpatica]

I just had this issue using:
XF 3.4.0.1008975
VS 15.9.3
Android Support 27.0.2
Minimum API level 6.0
Target level Android 9.0
FFImageLoading 2.4.4.859
Samsung Galaxy Tab 8.0 A running Android 7.1.1

It's random though. This is the second time I've seen it but it doesn't happen all the time.
I think some of the people above think they are fixing it but in reality, it just hasn't popped up again yet.

[RaashVision]

I have the same issue too using
XF 3.4.0.1008975
VS 17 15.9.3
Minimum API level 5.0
Target level Android 8.0
FFImageLoading 2.4.4.859
Oneplus 3 running android 7.1

I update to
XF 4.0.0.8055-pre
FFImageLoading 2.4.5.860-pre
its working now

Update : Test with android 8.0 its working too

[dblookup]

+1... same issues but with:
Xamarin Forms 3.2.0.871581
FFImageLoading 2.4.4.859
VS 15.8.7
Target level Android 8.0

[ckrempp91]

I can confirm the issue the same as @dblookup. I have attempted to follow the steps outlined by @mackayn in the earlier comment:

delete all obj & bin, close VS, clear %temp%, re-open VS, clear nuget cache, open solution, restore & rebuild

This does not remedy the problem for the call to FFImageLoading.Forms.Platform.CachedImageRenderer.Init within the MainActivity.cs file of the Android project.

I have attempted the following FFImageLoading NuGet versions:

• 2.4.4.859
• 2.4.5.860-pre

Xamarin.Forms: 3.2.0.871581
Visual Studio 2017: 15.9.4

Android SDK Levels:
Target: 27
Min: 15

I have also attempted this within two different xamarin forms apps, both resulting in the same exception of:
System.TypeLoadException: Could not load list of method overrides due to Method not found: void Xamarin.Forms.Platform.Android.IVisualElementRenderer.add_LayoutChange(System.EventHandler1<Android.Views.View/LayoutChangeEventArgs>)

I am attempting to take a look and see if there is a missing event hookup (per the exception received) that was added with the Xamarin 3.2 (and up) image modifications that were implemented for the ImageButton feature. I just wonder this because there have been large changes added that caused other images issues as well, like the issue with Images unable to be set to null for Android found here.

[pellet]

Upgrading from Xamarin forms 3.2.0.839982 to 3.4.0.1009999 fixed it for me.

[marthinch]

I also get the same problem here, i'm unable to init ffimageloading on main activity. I use xamarin form 3.4.0 and ffimageloading 2.4.4.

[alextorres50]

I clean All projects and Rebuild the solution and fixed for me

I had I use xamarin forms 3.4.0.1029999 and ffimageloading 2.4.4.859

[ArvindSJoshi]

2.4.5.860-pre resolved my issue. However, when is the planned release for that version?

[martijn-nap]

Same error here, FF 2.4.4.859 and XF 3.3.0
"System.TypeLoadException: Could not load list of method overrides due to Method not found: void Xamarin.Forms.Platform.Android.IVisualElementRenderer.add_LayoutChange(System.EventHandler`1)"

[kingces95]

Xamarin.Forms introduced a breaking change here. We added an interface event IVisualElementRenderer.LayoutChange. FFImageLoading implemented the old version of this interface. When XF is upgraded, then the interface contained a new event. When mono loads the updated XF, it expects all IVisualElementRenderer implementations to implement the new event. When mono goes to load the FFImageLoading type that implemented the old interface and discovers it doesn't implement the new LayoutChange event, then mono throws the exception you are seeing.

We plan to roll back this change with this PR.

We do not believe this will "re-break" FFImageLoading because we see that the implementation here of IVisualElementRenderer was not upgraded to include the LayoutChange event.

[PureWeen]

Looking at the current releases of FFIMageLoading.Forms it looks like the fix for the added interface is inside the 2.4.5-pre package but not 2.4.4

It's our plan to get this PR out https://github.com/xamarin/Xamarin.Forms/pull/5398 as soon as possible which will fix FFImageLoading when used with XF 3.6+

If the timing isn't right for 3.6 RC then we will definitely have the fix inside the next 3.6 SR1 release

I just wanted to get this note out before @daniel-luberda makes the 2.4.5 release official.

[daniel-luberda]

@kingces95 @PureWeen Thanks for info. I replied in XF issue.

[tualatin]

Hi, with the current Xamarin.Forms 3.6.xx I get the init exception too. Downgrade to XF 3.5.xx

[ChrisJAult]

Hi, I can confirm I get the same init exception with Xamarin.Forms 3.6 and 2.4.5 pre.

[xalikoutis]

Same error here for Xamarin.Forms 3.6 and 2.4.5 pre

[PostImpatica]

using...

• Xamarin.Forms 3.6.0.220655
• FFImageLoading 2.4.5.867-pre
  -- or --
• FFImageLoading 2.4.4.859

I get this error:

Unhandled Exception:

System.TypeLoadException: Could not load list of method overrides due to Method not found:
void Xamarin.Forms.Platform.Android.IVisualElementRenderer.add_LayoutChange(System.EventHandler`1<Android.Views.View/LayoutChangeEventArgs>) occurred

I also get the above error with this:

• Xamarin Forms 3.5.0.169047
• FFImageLoading 2.4.4.859

This seems to work

• Xamarin Forms 3.5.0.169047
• FF 2.4.5.867-pre

[PureWeen]

Now that Forms has rolled back the interface a new 2.4.5 pre version of FFImageLoading will need to be released.

Once that's released then it'll fix the exception

[mjspk]

Same same error here for Xamarin.Forms 3.6 and 2.4.5 pre

[PureWeen]

@mjspk

Now that Forms has rolled back the interface a new 2.4.5 pre version of FFImageLoading will need to be released.
Once that's released then it'll fix the exception

[dgonzalezp]

Same here XF 3.6.0.220655 FFIL 2.4.5.867-pre

[PureWeen]

@dgonzalezp

Once a new build of FFIMageLoading 2.4.5 is created against XF 3.6 then it won't crash

[dgonzalezp]

Thanks! Meanwhile v2.4.3.840 seems to be working.
XF v3.6.0.220655
FFIL v2.4.3.840

[samhouts]

@daniel-luberda FYI, 3.6.0 is stable now and contains the fixed API, so it's ready for a rebuild. Thanks!!!

[mazhiyuan1981]

use CachedImageRenderer.Init(true); at OnCreate(Bundle savedInstanceState)

Unhandled Exception:

System.TypeLoadException: Could not load list of method overrides due to Method not found: void Xamarin.Forms.Platform.Android.IVisualElementRenderer.add_LayoutChange(System.EventHandler`1)

xamarin.forms version:3.6.0.220665

oh my god... help me..

I can't live without FFImageLoading.

当使用xf版本：3.6.0.220665时，报错，请大家帮助我。谢谢各位。

[mazhiyuan1981]

I can only use it by rolling back to the previous version(xf:3.5.0.169047). But this is not a good idea.

我现在只能通过回滚到上一个版本(xf:3.5.0.169047)，才能使用。但这不是好办法。

[jbtamaresgit]

@mazhiyuan1981 Either downgrade XF to latest 3.5.x or downgrade ff image to 2.4.3.840 for awhile, as this worked on my end. They might push a new version for ffimage to fix the issue.

[mazhiyuan1981]

@jbtamaresgit
i see ...thank you very much...

[vipinkrishna131]

@jbtamaresgit downgrade ff to 2.4.3.840 worked for me

[haldocalypse]

I got this error too with XF: 3.6.0.220655 and FF: 2.4.4.859.

Downgrading FF to 2.4.3.840 resolved the issue.

[EmilAlipiev]

I think that downgrading is not a good solution. we had several fixes between those versions.

[scharada]

this is using XF 3.6.0.220655 and FF 2.4.4.859 and PRE version

[justin-typsy]

I too get the same error using the combinations @scharada and @haldocalypse mention. I've resolved by downgrading XF for the moment.

[angelru]

the same issue

[daniel-luberda]

Please check 2.4.5.870-pre. Cheers.

[gsgou]

Please check 2.4.5.870-pre. Cheers.

Works fine with XF: 3.6.0.220655
Thanks for the fixes and continuous support of this package!

[ravero]

I'm having the same issue here.
Downgrading to 2.4.3.840 solved, even being a weird solution.

[clintonrocksmith]

Using the 2.4.5.870-pre solves the issue for us. I'll be doing testing with this until it's released as stable. Will raise any issues I find. Thanks team

[Polyariz]

There is System.TypeLoadException in Android by using the 2.4.5.870-pre

[PureWeen]

@Polyariz that sounds like one of your binaries is off. Can you make sure all your nugets are the same version and try deleting your bin/obj folders

[Polyariz]

The same, bin and obj were deleted and the nuget's were removed and installed again

[bcaceiro]

Anyone tried the latest version with FastRendererers enabled? I'm getting the exception still.

[EaranMaleasi]

Updated from XF 3.4 to 3.6 today and got this error. For me FFIL 2.4.5.870-pre solved the problem. Using VS 15.9.7

[stesvis]

I don't know if anybody has noticed because I haven't read comments about it, but I just wanted to point out that as someone suggested, yes, "v2.4.5.870-pre" builds and deploys without errors, but most of my SVG images look bad now.
So I am gonna keep v2.4.3.840 which displays my images correctly.

[craigajohnson]

This is a great library but there does still appear to be a compat issue with Xamarin Forms 3.6. Any released or pre-release version of FFIL (e.g., 2.4.4.859, 2.4.5.870-pre, etc.) causes borkage on init. Maintaining plateau of Xamarin Forms 3.5 works however. So we are for the moment sticking with XF 3.5.

[danielsilvajobs]

As @stesvis said it works on v2.4.3.840 and the latest version of Xamarin Forms but it does not display my images correct.

Give a try on this one:
https://openclipart.org/download/159037/violin.svg

[LeoJHarris]

Seeing the same issue, deleting Bin/obj folders and rebuilding does nothing. Rolling back only resolves the issue.

[IoTFier]

Same issue on XF 3.6.0.264807 and latest stable of FFImageloading

[janbaltes]

Works with the latest XF 4.0 pre-release and version 2.4.5.870-pre of FFImageLoading

[ravero]

Well, but we need it working on stable releases.

[haldocalypse]

I got this error too with XF: 3.6.0.220655 and FF: 2.4.4.859.

Downgrading FF to 2.4.3.840 resolved the issue.

Issue was resolved using FFImageLoading version 2.4.5.870-pre and XF 3.6

[craigajohnson]

I can also confirm the above - 2.4.5.870-pre and XF 3.6.0.264807 are working. I'll leave it here pending formal release of the next FFImageLoading version.

[Ruddy2007]

@daniel-luberda Any ETA on a stable release for 2.4.5.870-pre?

[CarLoOSX]

working in pre

[jsauve]

Same as @EaranMaleasi and @craigajohnson: FFImageLoading 2.4.5.870-pre works with Xamarin.Forms 3.6.0.264807.

[HenrikPihl]

Same problem for Xamarin.Forms 3.5.0-sr2 (3.5.0.274416), this also needs FFImageLoading 2.4.5.870-pre

[cristhyanc]

It works after installing the 2.4.5.870-pre version,
Thanks for that

[xperseguers]

I confirm that the crash is gone with that pre-release version. Thanks.

[fjsosa]

Sorry, how can I download and install the pre-release version: 2.4.5.870-pre?

[IeuanWalker]

@fjsosa in VS package manager, there is a tick box next to the search that says 'Include prereleases'

[Monikaprime]

System.TypeLoadException: Could not load list of method overrides due to Method not found: void Xamarin.Forms.Platform.Android.IVisualElementRenderer.add_LayoutChange(System.EventHandler`1)

still error there for XF.3.6 and also cannot find option in include pre-releases please help

[xperseguers]

@Monikaprime You should just follow @IeuanWalker suggestion, this is as easy as that:

[aspnetde]

[aspnerd]

I'm having the same issue here...

[jelkevdh]

Same here

[mjfara]

Yup, same issue here:
Constructor on type 'FFImageLoading.Forms.Platform.CachedImageFastRenderer' not found.

[PureWeen]

So here's the rundown of version compatibles. Let me know if something here seems incorrect and I can update

As of now we rolled back the interface change that caused this initial headache on every XF 3 version. This change needed to be applied to XF 3.4, 3.5, 3.6 meaning that

https://www.nuget.org/packages/Xamarin.FFImageLoading/2.4.4.859

• is incompatible with the latest versions of 3.4, 3.5, and 3.6, 4.0 pre(*)

https://www.nuget.org/packages/Xamarin.FFImageLoading/2.4.4.859 and all 2.4.5 versions prior to
https://www.nuget.org/packages/Xamarin.FFImageLoading/2.4.5.880-pre
are compatible with:

• https://www.nuget.org/packages/Xamarin.Forms/3.6.0.220655
• https://www.nuget.org/packages/Xamarin.Forms/3.5.0.169047
• https://www.nuget.org/packages/Xamarin.Forms/3.4.0.1029999

https://www.nuget.org/packages/Xamarin.FFImageLoading/2.4.5.880-pre

• is compatible with the latest versions of 3.4, 3.5, and 3.6

https://www.nuget.org/packages/Xamarin.FFImageLoading/2.4.5.870-pre

• XF 3.6.0.264807

[fzany]

It works after installing the 2.4.5.870-pre version,
Thanks for that

Same here.

[PureWeen]

FYI
https://www.nuget.org/packages/Xamarin.FFImageLoading/2.4.5.880-pre

Is listed as coming out 2 days ago so updating to that might also fix your woes

I tested latest 3.6 against that version and everything worked for me

[candidodmv]

Its appear that "SvgCachedImage.LoadingPlaceholder" is not being replaced by svg file URL, someone can confirm if it's really a issue?

[candidodmv]

I found the cause: The Project was referering to version 2.4.5.880-pre insted of 2.4.5.870-pre

[KishorTiwari]

Works well with 2.4.5.870-pre and XF 3.6.0.264807. Thank you all.

[mackayn]

Yes, 2.4.5.870-pre and XF 3.6.0.264807 is good for me.

[PureWeen]

@candidodmv @KishorTiwari @mackayn

Out of curiosity why are you opting to use 2.4.5.870-pre opposed to 2.4.5.880-pre?

2.4.5.880-pre works with the latest version of XF 3.6.0.293080

[candidodmv]

@PureWeen as mentioned above https://github.com/luberda-molinet/FFImageLoading/issues/1154#issuecomment-480989539, with the version 2.4.5.880-pre is not loading svg files for me

Never Mind after a few tries it worked, also solved the issue

[mimunoz]

With 2.4.5.870-pre and XF 3.6.0.264807 combination, some images are showing in black and others good. I try with 2.4.5.880-pre and XF 3.6.0.293080 with no luck. Also, I delete bin/obj folders, clear nuget cache, rebuild and close VS 2019 for mac and continue with same issue.

[kmagalios]

In iOS (XF 3.6.0.293080, XF Visual Material 3.6.0.293080, Xamarin.FFImageLoading.Svg.Forms 2.4.4.859, VS2019) everything works fine.

I believe is Android's problem. I tried everything mentioned to the previous posts without luck!

[kmagalios]

After some research, the problem is related to Xamarin.Forms.Visual.Material!

When the CachedImage or SvgCachedImage are inside a, for example, StackLayout which has the property Visual="Material", then you take an exception.

I set, for CachedImage, the property Visual="Default" and everything works fine!

(XF 3.6.0.293080, XF Visual Material 3.6.0.293080, Xamarin.FFImageLoading.Svg.Forms 2.4.5.880-pre, VS2019)

BR.

[PureWeen]

@kmagalios

When the CachedImage or SvgCachedImage are inside a, for example, StackLayout which has the property Visual="Material", then you take an exception.

is there any special setup for this? Or literally any CachedImage/SvgCachedImage you use when set to material will cause an exception?

Do you have the stack trace of the exception by chance?

[daniel-luberda]

@kmagalios We could use a fix for this, see: https://github.com/luberda-molinet/FFImageLoading/pull/1246
Reflection is needed as we need to be backward compatible. What do you think? Can you confirm if non-default style is an issue?

[kmagalios]

@daniel-luberda Thank you for your reply. Reflection sounds ok to me! I'll check it at afternoon.

@PureWeen
If CachedImage/SvgCachedImage is hosted into a container (Frame/StackLayout etc) which has the property Visual="Material", then the value of the property is propagated to contained components. For this case you have to set Visual="Default" to CachedImage/SvgCachedImage.

If the property Visual is not set or is set to "Default" you don't have any problem.

The default value for Visual property is "Default".

[IbrahimElshafey]

SvgCahcedImage doesn't display anything after I updated to the pre-release version. The source of the SvgCahedImage is a resource file in the shared project and I use it like below:
<forms:SvgCachedImage Source="resource://SharedProject.Images.share.svg">
This code worked before the update.

[daniel-luberda]

@IbrahimElshafey Could you attach a repo?

[IbrahimElshafey]

@daniel-luberda while I create a sample to post it here I found it works fine, I will try to find the reason why it didn't work in the original project I worked on.

[IbrahimElshafey]

@daniel-luberda It seems that some images that were displayed correctly using the old version can't be displayed with the new one.
I created a sample that demonstrates that In this sample I display two images using the old version (2.3.6) and the other use the pre-release version (2.4.5.900), the old sample display both images correctly but the new one display only one image and the other is white.

[kmagalios]

@kmagalios We could use a fix for this, see: #1246
Reflection is needed as we need to be backward compatible. What do you think? Can you confirm if non-default style is an issue?

@daniel-luberda I've installed the latest preview version (2.4.5.900-pre) and everything works fine.
I remove the property Visual="Default" and everything is ok.

Thank you.

[daniel-luberda]

I pushed quite a lot of fixes and improvements lately. New prerelease package should be a lot more performant, especially on Android. I tested it while fast scrolling tons of images (also with poor internet connection scenario), not a single crash or exception and memory usage is lower than with previous versions. SVG parsing is also improved, etc.

I plan to release new stable. If you could test prerelease first and submit your feedback I would be grateful as I would like to fix all potential issues before a release.

[IbrahimElshafey]

@daniel-luberda I upgraded to the latest prerelease package but SVG images that were displayed by the old version (2.3.6) can't be displayed.

[Kiitoksia]

Also having this issue that IbrahimElshafey mentioned. Using the latest stable Xamarin Forms release.

[daniel-luberda]

• Which version of SkiaSharp do you use?
• Are you sure you have the same FFIL packages version in all projects?

[Kiitoksia]

SkiaSharp wasn't referenced in my project, so I guess it was whichever version is bundled with Xamarin?
Adding the latest SkiaSharp reference via Nuget fixed this issue.

[IbrahimElshafey]

@daniel-luberda First of all thank you, I very appreciate your work, FFIL is an essential package to any Xamarin.Forms project.
I use the same SkiaSharp version in all projects, the sample contains two Xamarin forms projects, the code in both is the same but in the old (SvgCachedImageTest_old) I use FFIL version as the image
the other one uses the latest pre-release version as the following

• the result of both project is different, The old version display both SVG fine but the new pre-release isn't
  
  

[daniel-luberda]

@IbrahimElshafey Thanks.

• You're not referencing all packages in your projects (Xamarin.FFImageLoading, Xamarin.FFImageLoading.Svg)
• The important thing is you should use the same package version in all your projects. Both images render just fine on latest prerelease package. Also:
• Always delete all bin / obj folders and then rebuild if you experience any problems.

[IbrahimElshafey]

@daniel-luberda Thanks for your response.
I added the missing packages and I deleted the bin/obj folders but with the new version the arrow image didn't display. bellow is the SVG for the image:

<svg xmlns="http://www.w3.org/2000/svg" width="8.5" height="14.9">
  <path fill="#f0f" d="M2.5 7.5a2 2 0 0 1 .3.2L8 13a1 1 0 1 1-1.5 1.5l-3.8-3.9L.4 8.2a1 1 0 0 1 0-1.6L6.6.4a1 1 0 0 1 1.8.4 1 1 0 0 1-.3 1L4.7 5.4 2.5 7.5z"/>
</svg>

If I deleted the fill attribute (fill="#f0f") it displayed fine, I tried this on two diffrent emulators and on my phone.

<svg xmlns="http://www.w3.org/2000/svg" width="8.5" height="14.9">
  <path d="M2.5 7.5a2 2 0 0 1 .3.2L8 13a1 1 0 1 1-1.5 1.5l-3.8-3.9L.4 8.2a1 1 0 0 1 0-1.6L6.6.4a1 1 0 0 1 1.8.4 1 1 0 0 1-.3 1L4.7 5.4 2.5 7.5z"/>
</svg>

[IbrahimElshafey]

@daniel-luberda I didn't want to waste your time If it works fine on your machine ignore the latest message because I use the old version in the real project and it works fine.

[daniel-luberda]

See screenshot above, it works. I just tested it on FFIL sample project:

[IbrahimElshafey]

@daniel-luberda It may be some packages cached on my machine I will try again.

[mackayn]

@IbrahimElshafey

Clear your Visual Studio nuget cache.

[IbrahimElshafey]

@mackayn I tried this already, I deleted all FFIL packages in the packages folder C:\Users\UserName\.nuget\packages\ but the problem still exists, I will compile source code locally.

[LeoJHarris]

Using 2.4.5.909-pre and Xamarin forms 3.6.0.344457 resolves this issue for me.

[HugoTruffe]

Hi

Using 2.4.5.909-pre (Core, iOS and Android) and Xamarin forms 3.6.0.344457 but the images are not visible.

[MaxenceSAUNIER]

I confirm

[Giorgi]

Same issue here, SVGs are not rendered

Please make sure you:

• have included all necessary packages in all projects, https://github.com/luberda-molinet/FFImageLoading/wiki/Xamarin.Forms-API#step-1 (including SkiaSharp)
• all packages all in the same version
• delete all bin/obj folders from all projects & rebuild

This worked, however, only the first time i run the app after a clean+delete obj/bin+rebuild.
After that, if i run the app again there is no error, but all my svg icons are invisible.
I would have to clean+delete obj/bin+rebuild the app every time to make it work....

Is there a reason?

I have install SkiaSharp and it's working. Thanks @daniel-luberda

I updated the Xamarin.Forms NuGet Package to the latest version and now I get an exception on OnCreate in Android (iOS untested so far).

Is there a solution to this problem?

commit your code or take a copy of your project.
After the apply this command on package manager console "update-package".
After this clean build your project, then restart visual studio and rebuild your project.
This procedure work for me.

Using version 2.4.4.859 works well with XForms 3.4.0.1009.
The following versions did not work for me (combined with the same XForms version above):

• 2.4.11.982
• 2.4.9.961

Hello,
it also crashes for me, I use FFImageLoading version 2.4.4.858-pre and Xamarin.forms 4.6.0.800.

It throws this exception:

System.TypeLoadException: Could not load list of method overrides due to Method not found: void Xamarin.Forms.Platform.Android.IVisualElementRenderer.add_LayoutChange(System.EventHandler`1)

I did everything requested here: https://github.com/luberda-molinet/FFImageLoading/wiki/Xamarin.Forms-API#step-1

I did not do:

Xamarin.FFImageLoading.Transformations (if you’ll use transformations like CircleTransformation)

Xamarin.FFImageLoading.Svg (for SVG support)

Xamarin.FFImageLoading.Svg.Forms (for SVG support)

SkiaSharp (for SVG support)

As it is optional - I don't use SVG, and I don't use transformations

@daniel-luberda, a BIG THANK for removing FATAL Error.
All good with VS 17.9.1, XF 3.4 except my image resolution issue that I talked about ..

Appreciate your help in making us look good. Many paid vendors struggle to reach this bar and level of understanding to serve their customers.

A big Applaud for your professionalism. Thank you !
