Xamarin Android 9.4.99.22 couldn't load 64-bit libjnigraphics.so library

[bksingapore90]

Steps to Reproduce

1. Install Xamarin Android 9.4.99.22 here on mac os : https://jenkins.mono-project.com/view/Xamarin.Android/job/xamarin-android/519/Azure/)
2. Make android app bundle format (*.aab)
3. use .aab file to install on 64-bit supported device.

p/s : I'm trying alpha version Xamarin Android 9.4.99.22 to use Android App Bundle . Maybe above issue is a problem in alpha version but I would like to know how to fix. thank you !

Expected Behavior

The lib libjnigraphics.so should be loaded in /system/lib64/

Actual Behavior

[Mono] DllImport error loading library '/system/lib/libjnigraphics.so': 'dlopen failed: "/system/lib/libjnigraphics.so" is 32-bit instead of 64-bit'.

The lib libjnigraphics.so was loaded in /system/lib/.
This is 32-bit version , exception happens and app is terminated

Hi @bksingapore90,

Do you know where this native library is coming from? How is it added to your project?

[Mono] DllImport error loading library '/system/lib/libjnigraphics.so': 'dlopen failed: "/system/lib/libjnigraphics.so" is 32-bit instead of 64-bit'.

Is it coming from a NuGet package or an AndroidNativeLibrary in your project?

In the meantime, I'll try to repro this myself. I can probably use any sample with a native library: sqlite or something.

[jonathanpeppers]

SQLite-Net seemed to work fine: master...jonathanpeppers:bundletool-nativelibraries

It looks like your stacktrace started with SkiaSharp:

I'll try a SkiaSharp sample next.

[jonathanpeppers]

Ok, I can reproduce the problem with this sample: https://github.com/mono/SkiaSharp/tree/master/samples/Basic/Android/SkiaSharpSample
(I just changed it to use the NuGet instead of building SkiaSharp from source: SkiaSharpSample.zip)

@bksingapore90 it seems like I can see the problem with APKs, too? Seems like it isn't anything to do with app bundles, it's just happening with latest xamarin-android/master?

[bksingapore90]

Do you know where this native library is coming from? How is it added to your project?

yes, in my case . it happens with Skiasharp library.
but simply , you can reproduce with this code in Xamarin.Android project (this code will load libjnigraphics.so - this is Android library available on device , I don't add it manually)

var bitmap = Android.Graphics.Bitmap.CreateBitmap(500, 500, Android.Graphics.Bitmap.Config.Argb8888);
bitmap.LockPixels();

@bksingapore90 it seems like I can see the problem with APKs, too? Seems like it isn't anything to do with app bundles, it's just happening with latest xamarin-android/master?

@jonathanpeppers yes, in furthermore investigation , I see it seems the problem is not in app bundle process. It is the problem with latest xamarin-android/master itself.
When you run debug (when aapt2 is enabled ) with above code, the problem still happens

[jonathanpeppers]

This is odd, I can add this test to Mono.Android-Tests.csproj and it works:

public void LockPixels ()
{
    var bitmap = Bitmap.CreateBitmap (500, 500, Bitmap.Config.Argb8888);
    bitmap.LockPixels ();
}

But if I add the code to a new project, I'm seeing the crash: BitmapTest.zip

[jonathanpeppers]

@bksingapore90 this should be fixed by: #3117

Give latest build from master a shot, and let us know. Thanks a lot, you helped us fix this before we shipped!
