APK vs AAB – Which is Better for Android?

While trading the last rendition of your application, you will be seeing two fundamental result designs for example APK and AAB. In this article, we'll attempt to investigate every one of them and pick better among them. 

  What is APK?

APK represents Android Application Bundle. It's a document design utilized by Android that contains an ordered variant of an application. It is utilized to appropriate and introduce applications across its biological system. They likewise incorporate a manifest document, giving application data to the Android framework, basic media assets like symbols and sounds, and a bunch of declarations and marking keys that confirm the distributer's personality. An APK document resembles a compress record that contains every one of the essential records, assets, and code expected to run an Android application on a gadget. 
  What is AAB? 

 AAB represents Android Application Group. It is a distributing design presented by Google in 2018, which permits engineers to distribute more proficient applications on the Google Play Store. AABs are a kind of group that incorporates all the ordered code, assets, and resources expected to construct an APK (Android Application Bundle), however it is a more effective approach to bundling than APKs. AABs just incorporate the code and assets required for a particular gadget setup, for example, a screen size, language, or surface pressure design. 

  Which is Better? 

 The primary contrast among APK and AAB in Android is the manner by which the application is bundled and conveyed to clients. APK (Android Application Bundle) is a conventional record design utilized for disseminating and introducing Android applications. It incorporates all the ordered code, assets, and resources expected to fabricate an application for all gadget designs, for example, unique screen sizes and dialects. At the point when clients download an application from the Google Play Store, they download a pre-fabricated APK record that incorporates all the code and assets, regardless of whether they are required. AAB (Android Application Pack), then again, is a distributing design that permits engineers to distribute more proficient applications on the Google Play Store. It incorporates all the ordered code, assets, and resources expected to fabricate an application, yet in a more productive way than APKs. AABs just incorporate the code and assets required for a particular gadget setup, for example, a screen size, language, or surface pressure design. At the point when a client downloads an application from the Play Store, the store creates a custom APK that incorporates just the assets required for the client's gadget. This implies that clients just download the pieces of the application that they need, which can result in more modest application sizes and quicker download times. The principal benefits of AAB over APK are that AABs are more modest in size, quicker to download, and consider dynamic component conveyance. Engineers can likewise refresh explicit pieces of the application without refreshing the whole application. In any case, AABs require more work to work than APKs and are as of now the main upheld design on the Google Play Store. We can sum up the distinctions between the two as beneath.

AAB file (Android App Bundle)

APK file (Android Application Package)

AAB is a publishing format that allows developers to publish more efficient apps on Google Play Store. APK is a file format used to distribute and install apps on a wide range of devices.
AABs are a type of bundle that includes all the compiled code, resources, and assets needed to build an APK, but it is packaged in a more efficient way than APKs. An APK file is like a zip file that contains all the necessary files, resources, and code required to run an Android app on a device.
AABs only include the code and resources needed for a specific device configuration, such as a screen size, language, or texture compression format. APKs include the code, resources, and assets needed to build an app for all device configurations, such as different screen sizes and languages.
When a user downloads an app from the Google Play Store, the store generates a custom APK that includes only the resources needed for the user’s device. When users download an app from the Play Store, they download a pre-built APK file that includes all the code and resources, whether they are needed or not.
AAB results in smaller app sizes. Since APK targets multiple device configurations, its size is more. 
AAB is faster to download. Download speed is slower when compared to AAB.
AABs require more work to build than APKs. APKs require less build time.
End 🔚

 All in all, which one is better? It relies upon your needs. To focus however many gadgets as could reasonably be expected and wouldn't fret bigger application sizes, then APK is as yet a decent decision. Be that as it may, if you need to enhance your application's size and download speed, then AAB is the best approach. It's actually important that, to distribute your application on the Google Play Store, you should utilize AAB design.
