Run React Native Expo App on Android Without Scanning QR Code

Introduction

When we create a React Native app using Expo, the common way to run the app on a phone is by scanning the QR code using Expo Go.

But scanning QR code is not always required.

We can also run the Expo app directly on an Android phone using USB debugging.

In this blog, we will learn how to run an Expo React Native app on Android without scanning QR code.

Project Details

In this example, we are using the project:

ExpenseTrackerFresh

Project path:

C:\Users\revansiddappa.kalshe\Documents\ExpenseTrackerFresh

npx
