React-Native project stuck on :app:installDebug
you can kill & restart adb in your terminal
adb kill-server && adb start-server
and start
react-native run-android
Try to change the USB port of your physical device. That worked for me.
I was running this on an emulator and ran into this issue. Tried all of the solutions on this page and none worked. Also tried just shutting everything down and restarting it - no luck. This is what worked for me:
1) In android studio, go to the Android Device Manager
2) For the emulator I was using, select then grey down arrow on the far right
3) Wipe Data
Relaunch the app and it worked fine.
