From android2.2 (froyo), Android has changed vold code.C Language, Changed to C ++, and fully inherits the framework, netlinklistener, and other general classes. Although the structure of the submitted vold is large, it can be inherited and scalable, but it also increasesCodeComplexity. This article is a good introduction to vold Analysis in Android. Bu
