Explanation of Android Application Context and source code analysis 1. Background Today, I suddenly remembered that when I was in my previous company (for TV and BOX boxes), several people asked me what the Android Context was, so I am about to give birth to this article. We are always using Context when developing an App (not to mention that you have never used Context when accessing resources of the curr

Note: The following source code is based on jdk1.7.0 _ 11 The Set set is actually an encapsulation of the map set. The map set stores key-value pairs, So we hide the values and do not expose them to the outside world. This forms the Set set.Corresponding to two very important implementations of the map set hashmap (based on the hash table), treemap (based on the red and black trees), the Set set also corresponds to two classes of hashset and treeset

Performance optimization in software development is a very important issue for programmers . A small problem can become a bottleneck for a large system. But it is very difficult for programmers to optimize their code by themselves. Fortunately, there are some great tools that can help programmers with code analysis and performance testing, making it much easier f

take a look at the source code for the Property_init function (/system/core/init/property_service.c): void Property_init (void) { init_property_area (); } The Property_init function simply calls the Init_property_area method, and then we look at the concrete implementation of this method: static int property_area_inited = 0; static works

? The finish function is not called, so it seems that the name is actually saved. With questions, we continue to look for answers in the source code. We can see that in the header file cctransition.

Below we will select a class for analysis. /** @brief TransitionRotoZoom:Rotate and zoom out the outgoing scen

first, the basic composition of the image file The image file loading time domain includes the RO and RW segments, while the runtime domain includes the RO, rw, and Zi three segments. Where the RO and RW segments contentIn load time and run timeis the same, but the storage space may be different, The zi segment is created by the initialization function at run time.RO segment: Read-only section, including the source program Code Segment， read-only data
