For the past one month, i have been doing development in React Native. I am using the expo-cli to create the project and using my physical Android phone for testing. It’s time to install the Android emulator on my laptop, so that i don’t have to check my phone every-time.

For this we have to install Android Studio 3+ first, so head over to this link or google it and download.

It is 724 MB for mac, so will take sometime to download. Once the dmg file is downloaded, you will get the below screen. You need to drag Android Studio to Applications

Now, start any of your completed React-native project by npm start. If you don’t have any yet, create one using my previous blog to create a Restaurant Search React-native app here.

Click on Run on Android device/emulator and it will try to open it. First time it will also install expo app on the Android simulator.
