Connecting with roboRIO over TCP

[Thardro]

This year we are attempting to do vision processing on an Android phone. We are creating a TCP connection over ADB, and then creating a ServerSocket on the roboRIO and a Socket on the phone, with each having a port 3042 and the hostname on the phone is roborio-3042-frc.local. When we try to accept the ServerSocket on the roboRIO, the program becomes stuck, indicating there is no connection. Has anyone else encountered this, and what can we do to fix the connection?
