42MB to display account information?! Use the Android APK Analyzer to reduce your APK size!

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. I cringe when I go to download a basic application (most of these apps are really simple) and the download size is over 40MB. Whenever I see this, if I have a bit of time, I like to dive into looking at what is bloating the APK.

Looking into these different APKs, I’ve come across some interesting files, from test data to iOS image files, I’ve seen it all. Whilst analyzing these APK files, I’ve noticed some common trends/mistakes that developers make.

I took a look at some of the Top(*) South African Android apps from the Google Play Store and found some interesting information. 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. [Disclaimer: I’m not displaying which apps did what — you can figure that out yourself (reach me on Twitter if you want me to help you lower your APK size). ]

The average download size of the Top(*) South African Android app is ~15.3MB — with the largest size sitting at ~ 42MB. 

The largest app on the store had 18.8MB of images and 14MB of native libraries packaged inside.

Okay, so I’ve hopefully gotten your attention. We know our apps are too big, but how do we go about finding this information and improving our apps?
