It could be tricky if you are coming from React for web and switching for React Native and thinking it could be an easy thing. 
It has some workarounds and for making it work it may differ depending on the android device plugged by usb. 

Setting the correct environment for your Android.

1. Enable debugging mode for USb. This is usually on Other Settings or Aditional Settings > Developer Options. Don't
close this windows for step 2.

2. On developer options switch ON the switch that goes by the name "Verifiy applications by USB". This allows your 
computer to manage and update the app from your linux pc.
