Describe the current behavior
I've built all dll's with docker, everything started to work on Windows, but when I build to Android it does not work on my Galaxy S7. Error that I get is:

and

when using ADB to see what happens.

Is there any tips for this @homuler?
mediapipe_android.aar looks fine after building and it works on Desktop. I have Load on startup enabled on libmediapipe_c.dll and opencv_world3410.dll.
I have "Use GPU" marked as well when building for Android.

I have only those in Streaming Assets, and not much more assetbundles, but nothing else appears when I do Assets>Build AssetBundles:

I also have those libs in .apk:

For everyone having this problem in the future -

It was a two-stepper so pretty hard to find and combine but here it is:

Before you build android library with docker you need to edit WORKSPACE file to include NDK api_level like this (according to this comment: google-ai-edge/mediapipe#1224 (comment)) :

You may run setup_android.sh to install Android SDK and NDK.

android_ndk_repository(
name = "androidndk",
api_level = 21,
)

@homuler can we edit WORSPACE file like this ^ for everyone? I've submitted pull request for this :)

and another important thing is that to have proper assetbundles build is to have properly configured meta files of *.bytes files that you have in Packages\com.github.homuler.mediapipe\Runtime\Resources folder.
By proper I mean editing them from this (I have checked diff according to this comment: #119 (comment) and I noticed it has been removed on import):

fileFormatVersion: 2
guid: eccb5de6967da1d4b80280b079b3ec2b
TextScriptImporter:
  externalObjects: {}
  userData: 
  assetBundleName:
  assetBundleVariant: 

to this:

fileFormatVersion: 2
guid: eccb5de6967da1d4b80280b079b3ec2b
TextScriptImporter:
  externalObjects: {}
  userData: 
  assetBundleName: mediapipe
  assetBundleVariant: 

and then do Assets>Build AssetBundles from the menu and you should be good to go :)
