We use Android emulators as well as real devices to run react native projects. If your PC has a good processor and enough RAM, running your react native project on Android emulator is simple.
I faced the react native android emulator error when I tried to run a react native project in Ubuntu. The emulator stuck at the green progress indicator showing Loading from 10.0.2.2:8081. There were no any signs to load the app.
This react native issue seems to be related with watchman. I ran the following commands in the terminal and the project ran smoothly.
echo 256 | sudo tee -a /proc/sys/fs/inotify/max_user_instances echo 32768 | sudo tee -a /proc/sys/fs/inotify/max_queued_events echo 65536 | sudo tee -a /proc/sys/fs/inotify/max_user_watches pkill node npm start react-native run-android
I hope the solution given above helps you to run react native project in your android emulator.
