I. Jia Lin's words:

APKThe combination of Application Framework (AF) and application development engineers is a result of their common wisdom. The operation of APK is the interaction between codes developed by AF and application development engineers.

Based on the experience of working with the father of Android and the android teams in Google, Samsung, and HTC, this course strives to give you a thorough insight into af from the perspective of designers, starting with the architecture and Transplantation of AF, then detailed with AMS, PMS, WMS code detailed verification and in-depth analysis, and finally to the end of the ANR thorough analysis.

Ii. What value does this course bring to you?

1,Experienced app development engineers:

1. Solving applicationsProgramFrequently Occurring intractable diseases, such as ANR and OOM

Second, the secrets behind the installation, running, and termination of applications are detailed.CodeIn-depth analysis;

Third, it is the quickest and most practical way to move from an application development engineer to an android architect;

2,Experienced Android Developers:

First, all the architectural design secrets inside the application framework are revealed, allowing you to port your hardware services into the AF as the cloud goes smoothly;

2. Control Android Application developers;

Third: understand how the top-level business architecture thinking is transformed into specific framework code;

3. target objects:

With at least half a year of experience in Android Application Development, the richer the experience, the better;

Experience in Porting Android systems;
