If you enjoy a fast-speed internet, you wouldn’t often care about the size of files that you download, as long as you get them quickly. However, if you have a slower internet, you sure would be bothered about the download size. Until now, users had to download completely new versions of apps from Google’s Play Store. However, now they can simply download smart updates.
Smart updates are implemented all around the web and are fairly popular. All you have to do is update your app and the new functionality that is a part of the new version is automatically download to your app. This way, you don’t have to go all the way to download the entire new version of the app, if you are already running the older one.
Google had announced this feature during its I/O conference in June and we have been expected it. Now that its finally here, users can get quicker updates to their apps without having to download the whole new APK file. Instead, apps will be able to download such data and functionality which is unavailable in their current versions.
Such smart updates are also referred to as ‘delta’ releases since they contain the difference between the old version and a new one. This update on the Play Store is implemented on the server-side so that the older versions of apps can also make use of it. To demonstrate how useful it is, the size of an Instagram update is reduced from 13MB to 3MB with smart updates.
