Android4.2-collection and display system module (frontier)

Frontier:

In view of the needs of project development, we have been learning the implementation mechanism of the Android video collection and display system at the underlying level since 2014. We have no foundation to crack the Code of these two modules, the main reference Blog is "journey to Android by Luo" and "Deng fanping's in-depth understanding of Android volume I and II". The content recorded by the Blog is mainly the difficulties and doubts encountered when I learned and became familiar with myself, as well as the special design ideas and coding methods in the Android architecture, I am here to share and learn with embedded developers. In view of my weak Java basic knowledge, I am mainly familiar with C ++-based Native-related content (in fact, C ++ is also a weakness of my own), which has many references, I hereby declare that there is no infringement, only for the purpose of learning together and making progress together.
