Android Application Bundles

Starting in August, 2021, the Google Play Store requires all new apps to be submitted in Android App Bundle (.aab) format. VoltBuilder can now create these bundles.

The only thing you need to do is add this line to your voltbuilder.json file:

"androidPackageType": "bundle",

VoltBuilder will then produce a file ending in .aab. These files are only used to upload to the Google Play Store: you cannot install them directly to a device. As a result, only release builds have this feature.

An Android App Bundle is a publishing format that includes all your app’s compiled code and resources, and defers APK generation and signing to Google Play.

Google Play uses your app bundle to generate and serve optimized APKs for each device configuration, so only the code and resources that are needed for a specific device are downloaded to run your app. You no longer have to build, sign, and manage multiple APKs to optimize support for different devices, and users get smaller, more-optimized downloads.

What VoltBuilder does

To start testing your app right away check out VoltBuilder!

VoltBuilder is a wrapper for Apache Cordova and Ionic Capacitor. We make it easy for you to build native executables (e.g., .apk, .aab, and .ipa) for Android and iOS from web apps. You can augment these executables with native code plugins to extend your app’s capabilities far beyond what is possible in Web Apps and PWAs.

Using VoltBuilder simplifies and speeds up your workflow while keeping things framework neutral. As a web service, there is nothing you need to install. We also keep everything up to date so you can focus on building to the latest standards, and make sure to keep you in the loop on things that might affect your build process.

The way VoltBuilder works is simple. Zip your project, upload it to VoltBuilder, and download your Android or iOS executable.
