Java Question SLC .aar lib and .so file

[warwound]

I'm wrapping part of the GoogleVR SDK and have a problem with the VrVideoView class:
https://developers.google.com/vr/android/reference/com/google/vr/sdk/widgets/video/VrVideoView

I started with the working demo project and created a wrapper.
The demo depends on 3 .aar libs from the GoogleVR SDK: common.aar, commonwidget.aar and videowidget.aar.
videowidget.aar contains a native .so library file and i'm unable to get this library to compile into my .apk (i'm using SLC to compile my library), as soon as i start my app i get an exception such as:

java.lang.UnsatisfiedLinkError: Couldn't load pano_video_renderer from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/mycompany.com.googlevrtest-2.apk"],nativeLibraryDirectories=[/data/app-lib/mycompany.com.googlevrtest-2, /vendor/lib, /system/lib]]]: findLibrary returned null

The .so file is located at:

videowidget.aar\jni\armeabi-v7a\libpano_video_renderer.so

My additional libraries folder contains the 3 required .aar files, and my Main activity contains:

	#AdditionalJar: common.aar
	#AdditionalJar: commonwidget.aar
	#AdditionalJar: videowidget.aar

Also, my wrapper class contains:

@BA.DependsOn(values={
        "common.aar",
        "commonwidget.aar",
        "videowidget.aar"
})

Looking at my .apk file using 7Zip i see various resources which belong to the varous .aar file but no .so file.

Any idea what the problem is?

Thanks.

The IDE doesn't do anything with the jni folder from the aar file.

You can create another jar with no code and only a folder named lib that holds the other three folders (from the aar).

Success - it works .
I actually added the .so file to my library source so it's compiled into my library jar instead of being a standalone jar.

Thank you.

Thinking about this...

Shall i create a feature request asking that the IDE fully supports .aar files - including compiling JNI files into the .apk?

Yes.

Yes.

Could this procedure be explained?
How do I create a jar with no code?

 

[DonManfred]

zip the lib folder
rename the some.zip to some.jar

That´s how i would try it

Look at the GoogleVR.jar library file from this thread - you might have downloaded it already:
https://www.b4x.com/android/forum/threads/google-vr.75628/

The download link is actually: http://b4a.martinpearman.co.uk/googlevr/GoogleVr_v1.20.zip

I created a dummy class to enable me to package my .so lib files into a codeless .jar file.
