C: \Users\Tutorialspoint\Desktop\MyReactNative>npm start

You’ll now get a QR code, once the above commands are implemented correctly. Use expo to run the react native apps on the Android version. Do the installation of the expo client on the Android device and scan the QR code that appears.

Ejection of the Project

Are you looking to use android studio for running the Android emulator? Press ctrl+c to come out of the current command line. Now, it is time to execute the run ‘eject command’ as

 npm run eject

It is a prompting option for ejection and thus select the first option with arrows and then press ‘Enter’.

Now choose a device definition and click on the ‘Next’ button. A System Image window appears in front of you and thus selects the ‘x86 Images’ tab.

Select ‘Marshmallow’ and then click on ‘Next’.

Finally, press the ‘Finish’ button to end the AVD configuration. Once the configuration of the virtual device is done, click on the play option under the ‘Actions’ column to get started with the Android emulator.

Run Android

Open the Command Prompt option, and browse through the project folder. Next, execute the ‘react native run-android’ command.

Now as the app execution begins, you can see the status in the next prompt.


Go to the project folder ‘SampleReactNative/android’ and click on the ‘Android’ option. It is time to create a file as ‘ ’and then add the necessary path –

Skd.dir = /C:\\Users\\Tutorialspoint\\AppData\\Local\\Android\\Sdk
Use your name in place of ‘Tutorialspoint’ and press Ok.

It is Time for Hot Reloading
