The largest app on the store had 18.8MB of images and 14MB of native libraries packaged inside. The average download size of the Top(*) South African Android app is ~15.3MB - with the largest size sitting at ~ 42MB. This blog post aims to show you how easy it is to look into your app and see what the biggest culprit of eating data in your app is.

Looking into these different APKs, I’ve come across some interesting files, from test data to iOS image files, I’ve seen it all. Whenever I see this, if I have a bit of time, I like to dive into looking at what is bloating the APK. I cringe when I go to download a basic application (most of these apps are really simple) and the download size is over 40MB. After looking around at a few Android applications, I realised that there are many developers who don’t know about a great tool in Android Studio - the Android APK Analyzer.
