mechanism between binder process is safe. Data behavior relationships between 4.Binder When client and server use the binder mechanism for interprocess communication, the client's specific behavior can be identified by analyzing the client's data sent to the server or analyzing the client's request data read by the server. For example, when the client wants to get the location information, the request Locationserver gets the location data, accesses the Locationserver Ilocationmanager interface,

The previous article introduced the "H264 video through the rtmp streaming", the following will explain how to H264 real-time video through the RTSP live. The realization idea is to send the video stream to the live555, and the live555 to realize the H264 data stream live. The video capture module sends the H264 data frame to live555 through the FIFO queue. After receiving the client's RTSP playback request, live555 reads the H264 video data from the FIFO and broadcasts it through RTSP. The enti

Android camera module architecture and bottom layer communication mechanism----------- Albert tchenThe Android Application Programming Language is Java, while many Linux service programs, including some libraries, are written in C or C ++, what kind of mechanism does an application use to call these system functions? Java virtual machines can use system. loadlibrary to load local libraries, or use the JNI function registernatives to register local methods associated with classes. In Android, mos

Figure 1 playbackthread family figure 1 explained a little: Threadbase is derived from thread, so it runs in a separate thread, programmers who do not understand multi-thread programming must learn multi-thread carefully ). It defines an enumeration type_t to represent the type of the subclass. These types include mixer, direct, record, duplicating, a

Since the Binder Mechanism has so many advantages, let's take a look at how it is implemented through the C/S model. 1.2 roles of binder in Service In Android, many services communicate through the binder. For example, mediaserver includes many services: Audioflinger core Audio Service Audiopolicyser
