@mattleibow since the fix is merged, when is it expected that a new stable version will be released?

@mattleibow as we are not allowed in our current project to use pre-release (preview) versions of a nuget, we also need a stable release with this change.

[Grzegorz1223]

@mattleibow with Android 16 already out for 2 weeks, this really starts to become a pressing issue.

[KevThompson2020]

Any update on this?

[shmoe01]

This will also be a issue for our team. Is there a plan ETA on the offical release?

unfortunately this repo receives very little love from the maintainers.

[jpmm94]

Please release new version compatible with 16kb page size @mattleibow is a huge issue with Android requirement with Google Play to release new app updates.

[mattleibow]

For now, a workaround is to just install the latest SkiaSharp NuGet package. This will update the version of skia that has the support.

I am working on getting this package stable and released. Just hittong some issues since all the CI was "disabled" but bots since it was such a long time since anything happened.

[KevThompson2020]

Thanks @mattleibow, I tried installing the latest skiasharp Nuget and it didn't work. I still get the warning about it.

[mattleibow]

Did you install the latest v3?

[KevThompson2020]

I tried SkiaSharp 3.119.0

Are there any others I need to try? I only had SkiaSharp and the extended Maui ui nuggets.

[mattleibow]

I think that is correct. I just did a test now and is says it is 16 KB aligned:

Elf file type is DYN (Shared object file)
Entry point 0x0
There are 10 program headers, starting at offset 64

Program Headers:
  Type           Offset   VirtAddr           PhysAddr           FileSiz  MemSiz   Flg Align

Specifically the LOAD headers 0x4000 is 16KB:

[mattleibow]

Maybe a clean is needed.

[KevThompson2020]

I did do a full clean ( deleted bin/obj folders etc ) but happy to try again in the morning. Will let you know.

[anotherlab]

@mattleibow, what tool did you use to check the LOAD headers?

I added skiasharp nuget and did a clean build, and I think I've eliminated the KB page size warning, but I want to be sure

[gabsamples6]

Hi all, I am a bit confused I am using SkiaSharp.Extended.UI.Maui 3.0.0-preview.13 and I am getting in google console that base/lib/arm64-v8a/libSkiaSharp.so does not support 16KB pages..

I dont have SkiaSharp as a package in my apps, are we saying I should bring this in together with SkiaSharp.Extended.UI.Maui 3.0.0-preview.13 ?

Will SkiaSharp.Extended.UI.Maui 3.0.0-preview.13 any ideas when this might be released?

Very grateful for clarification

@mattleibow

[Aguirrehub25]

Hola a todos, estoy un poco confundido. Estoy usando SkiaSharp.Extended.UI.Maui 3.0.0-preview.13 y en la consola de Google me aparece que base/lib/arm64-v8a/libSkiaSharp.so no admite páginas de 16 KB.

No tengo SkiaSharp como paquete en mis aplicaciones, ¿estamos diciendo que debería incorporarlo junto con SkiaSharp.Extended.UI.Maui 3.0.0-preview.13?

¿SkiaSharp.Extended.UI.Maui 3.0.0-preview.13 tendrá alguna idea de cuándo podría lanzarse?

Muy agradecido por la aclaración.

@mattleibow

Hola a todos, tengo la misma duda alguna respuesta?

[deepamhatre]

@mattleibow @Aguirrehub25 @Grzegorz1223 I have managed to get rid of the Android 16 KB page sizes warning by upgrading to the latest package version "3.0.0-preview.18"

[mattleibow]

Awesome. I am getting my pipelines going again and will do stable soon.

[Grzegorz1223]

Awesome. I am getting my pipelines going again and will do stable soon.

Hello, the deadline established by Google is approaching. What is the plan for the release schedule?

[ChristopherStephan]

@mattleibow @jfversluis Could you please publish a stable NuGet package release for this library? We rely on this urgently as the deadline approaches.

Starting November 1st, 2025, all new apps and updates to existing apps submitted to Google Play and targeting Android 15+ devices must support 16 KB page sizes.

[developer9969]

@mattleibow we have the same need - Office policy I cannot use it as a "prerelease" . Thank you

[Grzegorz1223]

@mattleibow thank you for fixing the pipelines, but I think that something is not right since the nuget repo was not updated with the latest version https://www.nuget.org/packages/SkiaSharp.Extended/#versions-body-tab

[mattleibow]

The 3.0.0 nugets should depend on the latest stable 3.119.1.

Maybe I am misunderstanding your question?

[ChristopherStephan]

11 hours ago a stable package was released. Thank you!

[Grzegorz1223]

Solved with the update :) Thanks!
