If you are converting a website into an Android app, you may encounter two common Android package formats: APK and AAB. Knowing the difference helps you choose the right build for testing and distribution.
What is an APK?
An APK is an Android application package that can be installed directly on compatible Android devices. It is useful for testing an app on a phone or sharing a build for controlled installation.
What is an AAB?
An Android App Bundle, or AAB, is a publishing format designed for app distribution. App stores can use the bundle to generate optimized packages for different devices and configurations.
Which one should you choose?
For hands-on testing, an APK can be convenient. For publishing through supported app-store workflows, an AAB is commonly preferred. A flexible website-to-app platform should let you choose the package format that matches your next step.
