Expo Build Android App Bundle - JavaScript

Expo is an open-source platform for building and deploying native iOS and Android experiences from a single codebase. With Expo, you can use your existing JavaScript skills to create truly native mobile apps that run on both iOS and Android devices.

One of the most convenient features of Expo is the ability to easily build an Android app bundle with just a few simple commands.

Prerequisites

Before you can build an Android app bundle with Expo, you need to make sure you have the following prerequisites installed:

• Node.js version 10 or later
• Expo CLI
• JDK (Java Development Kit)
• Android Studio
• A valid signing certificate (optional)

Building an Android App Bundle

Once you have all the prerequisites installed, you can build your Android app bundle by following these steps:

1. Install the necessary dependencies

npm install

2. Install the Expo CLI

npm install -g expo-cli

3. Create a new Expo project

expo init my-app
cd my-app

4. Build the Android app bundle

expo build:android -t app-bundle

5. Upload the app bundle to Google Play Console

After building your Android app bundle, you can upload it to the Google Play Console to distribute your app on the Play Store.

Optional steps

Use a custom signing certificate

You can sign your app bundle with a custom signing certificate by providing the following Gradle properties when building your app bundle:

expo build:android -t app-bundle --keystore-path /path/to/keystore --keystore-alias my-alias --keystore-password my-password --key-password my-key-password

Customize your app bundle configuration

You can customize your app bundle's configuration by providing a app.json file in your project directory. This file can contain various app configuration options such as icons, splash screens, and more.

Conclusion

Expo makes it easy to build and deploy native iOS and Android apps from a single codebase. With just a few simple commands, you can build an Android app bundle and distribute your app to millions of users on the Google Play Store.
