Android App Development enterprise-class best practices

One: The words of Jia Lin:

APK is the crystallization of the common wisdom of the AF (application Framework) and application development engineers, and the operation of the APK is the code interaction developed by the AF and application development engineers.

This course is based on the experience of working with Android's parent and Android teams in Google, Samsung, and HTC, and seeks to lead the designer to a thorough insight into AF, starting with the architecture and porting of AF, and then detailing the AMS, PMS, WMS's code meticulous validation and in-depth analysis ended with a thorough analysis of the ANR.

Second: What value does this course bring to you?

1, with Android app development experience application software Development engineer:

First: Solve frequently-occurring problems with applications such as ANR, Oom, etc.

Second: Application installation, operation, the end of the secret behind, and detailed code analysis to explore in depth;

Third: From the application development engineer to the Android architect the quickest and most practical way;

2, experienced Android system developers:

First: The application framework inside all the architectural design secrets, let you transfer your hardware services into the AF as smooth as flowing;

Second: Master Android app developer;

Third: How to understand the top business architecture thinking is transformed into concrete framework code;

Three: Suitable for the object:

Have at least half a year experience in Android application development, the richer the better;

Experience with Android system transplant;
