Question

I am developing a simple app using React Native. I am testing it on Android device. I have created a Node.js server to listen to the requests, it is running at http://localh

Answer 1

Use the reverse command of the Android Debug Bridge tool (adb):

adb reverse   - reverse socket connections.
                               reverse specs are one of:
                                 tcp:
                                 localabstract:
                                 localreserved:
                                 localfilesystem:

For example:

adb reverse tcp:3333 tcp:3333

This makes localhost:3333 accessible from your device. You can also use different ports. For example:

adb reverse tcp:8081 tcp:3333

This will redirect the device port 8081 to the local port 3333.
