What makes the miniature Hello World Android APK so big - 800 KB?

Question

This is currently not a general concern about bloating Android ^* apps, but a very specific question:

If you install Android Studio 2.3.3 and create a sample Hello World application (as described in the official “ Creating Your First Application” tutorial ) and then create an APK release, the file size is 825 KB (I tested this on Linux, but I suspect the output is the same on other OSs).

I have already enabled ProGuard and there are no images or other resources .

What is included in this apk by default?

What for?

How to remove this twist?

For comparison, in 2013, the Hello World application was under 10 KB .

_{* I remember when decent full-featured applications were several hundred kilobytes, and for comparison, PWA, such as Uber, is 1% of the size of the corresponding Android application}

Answer 1

It turns out that by deleting all kinds of resources and using crazy compression, an empty APK can be reduced to 678 bytes (!).

AppCompat, 100 .

build.gradle "": compile 'com.android.support:appcompat-v7:26.+
