Question

I used the react-native Android demo project AwesomeProject and within the project I executed:

react-native start

In a second terminal:

There is a small work around for this. Anyone running this on a physical device(or even otherwise) can restart their adb session using a different port.

eg.

react-native start --port=1234

On a different cmd/terminal window.

react-native run-android

After which I am greeted by these messages.

BUILD SUCCESSFUL

Total time: 22.589 secs
Running C:\SDK/platform-tools/adb -s VY0025160560725694 reverse tcp:8081 
tcp:8081

This runs it on default reverse port of 8081, which is blocked by McAfee.

Work around:

adb reverse tcp:8081 tcp:1234

Try it out. It works for me.

Note: You may have to kill and re-open the app.

Currently I am unable to provide an answer for an emulated device since I do not have one installed on my system. But the symantics should be similar.

Note: This may break automatic code updates using watchman.
