Expo Build Android - Javascript

If you're building a React Native app using Expo, you may need to build an APK file for Android devices. This can be done easily using the expo build:android command.

Prerequisites

To build your app for Android, make sure that you have the following:

• A paid Expo Developer Account
• A valid Keystore file and password. This is required to sign your APK file.

Build Process

1. Run expo build:android in your terminal.
2. Select the build type (apk or app-bundle)
3. Provide the path to your Keystore file and password.
4. Wait for the build process to complete.

APK Signing

After the build process is complete, you will need to sign your APK using the following command:

expo build:android:sign -t apk --keystore [path-to-keystore] --alias [keystore-alias] --ks-pass env:KEYSTORE_PASSWORD --key-pass env:KEY_PASSWORD [path-to-apk]

Make sure to replace [path-to-keystore], [keystore-alias], [path-to-apk], KEYSTORE_PASSWORD and KEY_PASSWORD with your own values.

Uploading to Google Play Store

To upload your APK to the Google Play Store, follow these steps:

1. Go to the Google Play Developer Console and create a new app.
2. Fill in all the required information and upload your APK file.
3. Wait for the APK to be processed.
4. Publish your app to the store.

Conclusion

Building an APK file for Android using Expo is a simple process. Once you have your Keystore file and fulfill the prerequisites, you can use the expo build:android command to build your APK and then sign it using the expo build:android:sign command.
