Erik was raised in the dark woods of Sweden, where the was nothing to do but to learn how to write code for PCs. After many years of suffering through experiences of early C++, Visual basic, Delphi, and every version of Java and C#, he has now found Kotlin and feel comfortable that the future for software is bright again.

Developing system apps without AOSP
If you work with Android development long enough, there is a high chance that you eventually will be developing system applications for a custom Android device. This is quite different from doing regular apps we publish on Google Play Store, and used to require that you have the entire AOSP source code checked out in order to work with it.
However, with some understanding of how Android internals work and how to use some undocumented features of the regular build tools, we can actually develop system apps without the whole mess that comes with AOSP.
In this session you'll learn how to use system and signature level permissions, how to efficiently call system APIs, and how to test all of this on a regular Android emulator. Hopefully this will make the daily life easier for all the Android developers working on system applications.
