Developing System Apps Without AOSP

Discover how to develop Android system applications without relying on the full Android Open Source Project (AOSP) in this 35-minute conference talk by Erik Hellman at Paris Android Makers by droidcon 2023. Learn the intricacies of creating system apps for custom Android devices, a process that traditionally required access to the entire AOSP source code. Explore techniques to leverage undocumented features of regular build tools and gain insights into Android internals. Master the use of system and signature level permissions, efficiently call system APIs, and learn how to test these applications on a standard Android emulator. Acquire valuable knowledge that will streamline the development process for Android developers working on system applications, making their daily work more efficient and manageable.
