CodePudding user response：

running adb devices after running adb kill-server. Security question pops up after that. Worked for me.

CodePudding user response：

1/ run npm start

2/ go to http://localhost:19002

3/ press on Lan and copy the URL under it eg. exp://192.168.1.3:19000

4/ download expo app in your device from your android studio.

5/ open expo and click Enter URL manually and paste the URL u copied in the previous step

6/ if needed: reload by clicking "r" button in your command line

CodePudding user response：

Try to:

1 Launch the android emulator (any sdk is fine as any model)

2 open the settings IN the emulator

3 activate developer mode
