Getting “error: closed” twice on “adb reverse”

Question

I am trying to reverse-forward port through ADB, but it just returns cryptic error of error: closed. Normal forwarding works. Session snippet:

$         


        

Answer 1

Follow these steps carefully.

Note: All commands need to run inside a project only.

1. Run this command first:

   npm react-native start
   

2. Open another window in the same project and run:

   curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"
   

3. This will create index.android.bundle in the assets folder

4. Run:

   npm react-native run-android
   

Now you can get apk in the build folder which will work fine.
