There is a few things you can try to solve this.
From the React Native official docs (https://facebook.github.io/react-native/docs/troubleshooting) you could try to "terminate the process on port 8081" by running:
$ sudo lsof -i :8081
$ kill -9 <PID>
You will run the second command on all PIDs that are using port 8081 (this will terminate your emulator too).
Then, restart the emulator and in one terminal, run:
$ npm start
and on a second terminal:
$ react-native run-android
Hope this can help!
