Issue ID

UUM-1385

Regression

Yes

Unity process are sometimes running on TCP in port range 5555 - 5585 which conflicts with adb

-

To reproduce:
* not consistently reproducible, retry steps if needed
1. Open terminal and execute "adb kill-server"
2. Open a new project
3. Open terminal and execute "sudo netstat -tulpn | grep "Unity""
4. Look for processes running on "0.0.0.0:5555"
5. Execute "adb devices"
6. Observe "emulator-5554 offline"

Reproducible with: 2018.3.0b5, 2018.4.0f1, 2019.1.1f1, 2019.3.0a2
Unable to reproduce with: 2017.4.27f1, 2018.2.21f1

Unable to reproduce on Windows, MacOS

Some Unity process (most often UnityShaderCompiler) uses TCP address 0.0.0.0:5555 which conflicts with ADB emulator port range (5555-5585) https://developer.android.com/studio/command-line/adb#howadbworks

When a user starts up an adb client with 'adb devices' command, adb sees port 5555 being used and thinks that there is an android device/emulator that is offline (see issue.png screenshot). The issue with this is that a user cannot build the project for Android player until the "offline emulator" is hanging.

Workarounds:
- kill the process that uses port 5555
- execute terminal commands "adb kill-server && adb devices" until the "emulator-5554 offline" no longer appears

  1. Resolution Note:

    As we are moving towards the deprecation of OpenRL, we are not going to invest any more of our resources into fixing issues like this. As we can see there are multiple workaround and the issue is not consistently reproducible, we have deprioritized this in favor of a dull reprecation of OpenRL in future releases.
