How to Create an APK for Production Using Expo and Submit It to the Play Store

Introduction

So, you've built a fantastic React Native app with Expo, and now you're eager to publish it on the Google Play Store. But wait—how do you generate a production-ready APK? Worry not! In this guide, I'll walk you through the entire process step by step.

Step 1: Install Expo CLI (If Not Installed)

First, ensure you have Expo CLI installed. If not, run:

Also, make sure you’re logged in to your Expo account:

Step 2: Configure Your App

Before generating the APK, check your app.json or app.config.js file. Update the necessary details like the app name, package name, and version.

Example app.json:

{
  "expo": {
    "name": "MyAwesomeApp",
    "slug": "myawesomeapp",
    "version": "1.0.0",
    "orientation": "portrait",
    "icon": "./assets/icon.png",
    "android": {
      "package": "com.yourcompany.myawesomeapp",
      "versionCode": 1,
      "permissions": []
    }
  }
}

Ensure that android.package is unique (matching your domain, like com.yourcompany.myapp).

Step 3: Build the APK File

Since Expo no longer supports “expo build:android”, you’ll need to use EAS Build instead. Run the following command:

Then, initialize EAS:

Now, to build an APK, use:

This will generate an APK for testing purposes. For a Play Store-ready build, use:

Once the build is complete, you’ll get a download link for your APK/AAB file.

Step 4: Sign Your APK (If Required)

Expo automatically handles signing, but if you want to manage keys manually, generate a keystore:

Follow the prompts to generate and download your keystore.

Step 5: Test Your APK on a Physical Device

Download the APK file and install it on your phone:

Alternatively, share the download link generated by Expo.

Step 6: Submit to Google Play Store

1. Create a Google Play Developer Account

If you haven’t already, register at Google Play Console (one-time fee of $25).

2. Create a New App

• Click Create app
• Set your app name, language, and category
• Choose App (not Game) and Free/Paid option

3. Upload Your AAB File

Since Google now requires AAB instead of APK, make sure you generated the AAB file (--profile production). Upload it under Production > Create new release.

4. Complete Store Listing

• App Name & Description
• Screenshots (Minimum 2, for phones and tablets)
• Feature Graphic (1024x500 px)
• Privacy Policy URL

5. Submit for Review

Once everything is set, click Submit for Review. Google will review your app (typically within 2–7 days).

Conclusion

Congratulations! 🎉 You've successfully created a production-ready APK (or AAB) and submitted your app to the Google Play Store. Now, grab some chai ☕ and wait for your app to go live!
