I write some code in Java on my PC using JAIN SIP 1.2, now I want to export some of my work and create new ones for Android, but I can't understand how to do it. I see another posts like Android-ready JAIN-SIP library? that redirect to a Github repo, where I can't find any documentation, or I don't know where to find it, to how to add JAIN SIP to android.
I found another ways to use JAIN SIP from older post: using two jar, adding them to my Android project: https://mvnrepository.com/artifact/javax.sip/android-jain-sip-ri/1.3.0-91 and https://mvnrepository.com/artifact/javax.sip/jain-sip-api/1.2.1.4 but I get a lot of compilation errors.
Clarify that I'm not familiar with implementing jar files in Android.
I just want to make a presence service, subscribing my phone to my computer just for receive some data, that I've already write and it's functional on my computer.
Thanks in advance.
