I am building React Native app.
It is working well when I launch the app in terminal on Mac using "react-native run-android".
But when I got the apk file and installed it on another android device manually, it does not work.
It looks like this.

React Native combines the best parts of native development with React, a best-in-class JavaScript library for building user interfaces. Use a little—or a lot. You can use React Native today in your existing Android and iOS projects or you can create a whole new app from scratch.
Simply pull up your device's browser and type in the IPv4 Address you copied down earlier followed by a colon and then the port number. The format should look something like the following: 555.55. 55.555:1234 once you hit enter, you should see your React App live on your mobile device!
If you are connected via cable, do the following:
On Windows open Android SDK Manger > Platform Tools
Type:
$ adb devices This will show you the devices and simulator/virtual-devices that you have on you computer.
Type:
$ adb reverse tcp:8081 tcp:8081 Type:
$ npm run android The app should appear on your device
