Introduction
Books
Computer books
Android core principles and efficient system-level application development is a technical book that introduces Android core development. Its main goal is to allow Android Developers to gain a deeper understanding of the Android system, make the development process more accurate and efficient. This book is mainly composed of two parts. It consists of 1st articles that describe the structure of the android core framework layer from the bottom up and include the development skills and key points. 2nd articles focus on the system-level application layer, focus on the key aspects of Android development.
Android core principles and efficient system-level application development presents the software structure of a huge Android system systematically and rationally for developers at the Android system level; android Application developers can use this book to gain a deeper understanding of the system and expand development methods. Developers engaged in Android hardware transplantation can use this book to gain a deeper understanding of the global system.
