Google Play to Publish New Apps on Store With Android App Bundle Starting  August | Technology News


Android app bundles were launched in the android appstore in May 2018. Since then it was seen that the developer community embraced this new standard willingly and benefited a great deal. There are approximately 1 million apps now that use app bundles in production. The most common apps on android app store that use the features of app bundles are: adobe, duolingo, GameLoft, RedBus, Netflix, twitter and riafy and many more.


Android is now focusing on bringing these benefits to more and more users by bringing more apps on the android appstore that make use of the android app bundle or (aab). By doing this APK will be replaced as the standard publishing format.

If you still haven’t made the switch to the android app bundles, these are some of the benefits you are missing: android app bundles, play app signing, play feature delivery, play asset delivery as well as other future developments.


  • Android application bundles: Google play uses android application bundles to optimize and generate APKs for device configurations and languages. With the help of android application bundles you can make your android application smaller in size, which further makes your android application faster and easier to download.
  • Play app signing: play app signing is a very integral part of the android app bundles and is required to protect your app signing key from loss. It makes use of Google’s secure infrastructure and offers you the opportunity for updating in future.
  • Play feature delivery: more than 10 per cent of the android development apps that use app bundles use this feature. By using play feature delivery you get the choice of customizing what feature modules are delivered to which device, when is the feature module delivered, with install-time, conditional and on demand delivery modes.
  • Play asset delivery: using this feature you can reduce the user waiting time by dynamically delivering large assets while cutting delivery costs. This allows the users to get assets that are suitable for their device. This helps them save their time and efforts.

The app bundle requirement applies only on the new apps. Those apps which already exist are exempt from this feature.




Q1)  how much work is required to work an APK vs an app bundle?


Answer) in the case of most apps very little work is required to build an android app bundle instead of an APK. The android app bundle is an open source format which is supported by major build tools like android studio, gradle, bazel, buck, cocos, creator, unreal engine, unity and many other engines. Features like Play Core Native and Play Core Java & Kotlin SDKs also make it easy to start using optional and advanced app bundle features, whatever your preferred environment for coding..


Q2) Why aren’t expansion files (OBBs) supported with app bundles? Why should games use Play Asset Delivery?


Answer) in the case of APKs there are separate files required. These files are known as OBBs. But, as OBB’s are not stored in the app’s external storage, they’re not very safe. With the help of play asset delivery (PAD), games which are larger than 150 mbs can replace OBBs. This will be done by publishing the game as a single app on play store. Along with offering flexible delivery modes and a smoother publishing process, PAD carriers also benefit over the files which are expanded over legacy.


Q3) Is it possible to change my app signing key?

Answer) the short answer is, yes. Some apps have the feature which enables them to request an app signing key upgrade for new installs in the play Console. Google play has a feature using which it can use your new key to sign new installs and app updates while also using your legacy app signing key to sign the updates for users who have installed your app before the key upgrade took place. It won’t be long before play app signing key upgrade also supports for APK signature scheme v3 key rotation. After this, key upgrade will be made a possible option for more apps and help apps signed with upgraded keys reach more users. It will make this feature more widely used.


Q4) When I am distributing apps on Google play, how do I make sure that my app is delivered to the users the same way that I intended?


Answer) in the play console from the app bundle explorer using play developer API to verify your app you can download and inspect artifacts from play store. In addition to this there is a new feature that can be used to inspect and check that the code running on a device matches the code that was originally intended to be built and was signed by the developer. This feature provides code transparency for app bundles.
