TCP not listening on Android 9.0 Pie with Proxy SIP Server.

TCP not listening on Android 9.0 Pie with Proxy SIP Server.

No incoming calls when using SIP over TCP on Android 9.0 (Pie).
Caller can initiate calls, but Callee doesn't receive the incoming SIP INVITE.
This doesn't work when Kamailio SIP Proxy is used. It works, with TCP, however when sipDroid runs on Android 7.0 (Nougat).
When UDP is used for SIP, the call gets established. The incoming INVITE is received. But, there is no audio both ways.
With Android 7.0 and UDP, the call works. Both SIP and Audio are OK.

Has anyone experienced similar incoming calls issues with Android 9.0?

Thank you,
Rabah

Just import Project from Android Studio and fix highlighted errors.
