Android Question [SOLVED] Error compiling with B4A 14.2 R8 Enabled (PDFium?)

[josejad]

Hi:

I get these errors probably related witn PDFium:

Error: Missing class android.support.annotation.Nullable (referenced from: com.github.barteksc.pdfviewer.model.PagePart com.github.barteksc.pdfviewer.CacheManager.find(java.util.PriorityQueue, com.github.barteksc.pdfviewer.model.PagePart))
Missing class android.support.v4.util.ArrayMap (referenced from: void com.shockwave.pdfium.PdfDocument.<init>())
Compilation failed
Exception in thread "main" java.lang.RuntimeException: com.android.tools.r8.CompilationFailedException: Compilation failed to complete
    at com.android.tools.r8.internal.Nu.a

Updated Core.proguard rules will fix this issue. Put it in the internal libraries folder.

If you encounter other issues at runtime then please post.

Hi Erel:

Thanks for the update. Still getting the error (I think it's the same). If you need to test it, it happens too with the demo app from B4XDaisyUIKit. You can download it from Google Drive or github from the link:

[B4X] [B4A] B4XDaisyUIKit - Native Components inspired by DaisyUI & Tailwind

Hi Fam Please note the source of truth for all the working examples for this library will always be the latest demo source code from github/google drive, use that rather as a reference point for your development. The library is still under development and sometimes things change and perhaps...

www.b4x.com

I created a new project with pdfium library and compiled it. I didn't get any compilation error after this change.

Maybe the file wasn't copied to the correct place. Add a rule in the manifest editor:

AddProguardText(
-dontwarn **.annotation.**
)

 

[josejad]

Added to the manifest. Same error. Maybe the problem is not PDFium itself.
The B4XDaisyUIKit sample still gets the error.

Not sure if this can be a clue: "Caused by: [CIRCULAR REFERENCE: com.android.tools.r8.internal.g: Missing class android.support.v4.util.ArrayMap (referenced from: void com.shockwave.pdfium.PdfDocument.<init>())]"

It is best if you post the full text from the compilation window.

Hello Jose,
Give this a go, even thought I don't think it will make any difference.

AddProguardText(
-dontwarn android.support.v4.util.**
)

Hum... If I edit the post, I see the "SPOILER", but no when it's published. Fixed.
