How can I use jar library files in Fuse?

I am a novice fuse developer. I would like to finally create a WeChat Login using a jar file.

But I do not even know how to use basic jar files in fuse yet. Is it possible to use a Android jar file in fuse?

Please tell me
Thanks.

Hi!

Please have a look at ForeignCode. Also, there are some examples of how to do this at https://www.fusetools.com/docs/native-interop/facebook-login and https://github.com/fusetools/fuse-samples/tree/master/Samples/AmazonS3
