解决方案

I met this. Finally I found that I have installed app in the phone. I solved the problem when i have uninstalled the app and run with different port like:

Before Uninstall

  1. The emulator is running press CMD + m (Mac) or CTRL + m (Windows). Select Dev Settings and then Debug server host & port for device. Enter the url with the new port(9988).
  2. CMD + R or CTRL + R and the application should reload with the new bundle.
  3. uninstalled app
  4. Run app with this command such as: react-native start --port 9988
