In this article, we will explain what an aab file and an apk file are, why you might want to convert one to another, how to do it online, and how to test the resulting apk files. By the end of this article, you will have a better understanding of these file formats and how to work with them.
What is an aab file and what is an apk file?
An aab file stands for Android App Bundle. It 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.
An apk file stands for Android Package. It is a package file used to distribute and install apps on Android devices. It contains all of a program's code (such as .dex files), resources, assets, certificates, and manifest file. You can build and sign APK files from Android App Bundles or directly from your source code using tools such as Android Studio or Visual Studio.
So, why would someone want to convert an aab file to an apk file? There are several reasons, such as:
To test your app locally on an emulator or device before uploading it to Google Play.
To distribute your app outside Google Play, such as on your own website or other app stores.
To install your app on devices that do not support split APKs or app bundles.
To inspect or modify the contents of your app's APKs.

Using bundletool command line tool
Bundletool is a tool that Google provides so that developers can perform local device testing before submitting app bundles to Google Play. It can also be used to generate APK files from an AAB file using the following command:
bundletool build-apks --bundle=/MyApp/my_app.aab --output=/MyApp/my_app.apks
This will generate an .apks file, which is a ZIP archive that contains one or more APK files for different device configurations. You can then extract the .apks file using any ZIP tool and install the desired APK file on your device.
If you want to generate a single universal APK file that works on all devices, you can add the --mode=universal flag to the command:
bundletool build-apks --bundle=/MyApp/my_app.aab --output=/MyApp/my_app.apks --mode=universal
This will generate an .apks file that contains only one universal.apk file inside. You can then rename the .apks file to .zip and extract the universal.apk file using any ZIP tool.
If you want to generate a signed APK file that can be installed on any device without requiring developer mode or unknown sources enabled, you can add the --ks flag and other signing parameters to the command: [^2 Using online converter websites

How to test apk files generated from aab files
Once you have converted your aab file to an apk file, you may want to test it before publishing or distributing it. There are two main ways to test apk files generated from aab files: using Android emulator or device, or using Google Play Console or App Bundle Explorer.
Using Android emulator or device
The simplest way to test an apk file is to install it on an Android emulator or device. You can use tools such as Android Studio or Visual Studio to run an emulator on your computer, or connect your physical device via USB. Then, you can drag and drop the apk file onto the emulator or device, or use the adb command line tool to install it. For example:
adb install /MyApp/my_app.apk
This will install the apk file on the emulator or device and launch it. You can then interact with the app and check its functionality, performance, and appearance.
Using Google Play Console or App Bundle Explorer
If you want to test how your app will behave when downloaded from Google Play, you can use Google Play Console or App Bundle Explorer. These are tools that allow you to upload your app bundle or apk file and see how Google Play generates and serves optimized APKs for different device configurations. You can also download and install these APKs on your emulator or device for testing.
To use these tools, you need to have a Google Play developer account and create an app entry in Google Play Console. Then, you can upload your app bundle or apk file as a draft release in the internal testing track. After that, you can go to App Bundle Explorer in the left menu and select the device configuration you want to test. You can then see the details of the generated APKs for that configuration, such as size, version code, permissions, features, etc. You can also download the APKs by clicking on the download icon next to them.
