Android API level 30 (might not be an issue with this repo)

[jtabraham123]

Hi, I am currently building an app that targets android api 30+ with ros2_java. However, for some reason I cannot get ros2 talker and listener nodes to communicate in api 30. It works in api 29 (I have followed example from https://github.com/YasuChiba/ros2-android-test-app). The talker and listener node can communicate locally on the app, but cannot talk to other devices with nodes on the same network? Has anyone else had this issue with api 30 and know a workaround?
