Failed to connect to development server using "adb reverse"

Question

I'm running a react-native app with an android emulator running normal, but when I use the command "react-native run-android" that launch me this error :

warn Failed to connect to development server using "adb reverse": spawnSync C:\\Users\\HP-Envy\\AppData\\Local\\Android\\Sdk;/platform-tools/adb ENOENT

Answer 1

Please try this:

$ adb reconnect

This is not necessary in most cases, but just in case, let's reset your connection with your mobile and restart adb server. Finally:

$ adb reverse tcp:8081 tcp:8081

So, whenever your mobile device tries to access any port 8081 on itself it will be routed to the 8081 port on your PC.

Answer 2

I got the same issue. You need to update the ANDROID_HOME path of your system.

Paste this in your terminal

export ANDROID_SDK=/Users/<your_computer_name>/Library/Android/sdk
export PATH=/Users/<your_computer_name>/Library/Android/sdk/platform-tools:$PATH
