It wraps this Github project. It extracts facial states and facial landmark information from a photo (bitmap) containing a human face. See the pic below...

2. The B4A library files (AndroidVisionFaceViewLibFiles.zip)
3. The java code as it stands at present (TheJavaCode.zip)
4. A link to all the other jars that will be required - download them from here and copy them to your additional library folder - https://www.dropbox.com/s/se5x5znl1tgpv6r/OtherLibFiles.zip?dl=0
5. resourceAdditionalLibFolder.zip - extract it and copy the resource folder to your additional library folder
6. resource.zip - extract it and copy the resource folder to the same folder level that of the /Files and /Objects folders of the B4A project.
You can download and test it but if you want to use it then you need to
