blueprint binder

In Android, each application is made up of activity and service that are likely to run in the same process or run in different processes. So how do you communicate with an activity or service that is not in the same process? This is the binder interprocess communication mechanism to be introduced in this article. We know that the Android system is based on the Linux kernel, and the Linux kernel inherits and is compatible with the rich Unix system int

5.3 Statement of Binder in Driver Driver is the core of Binder communication. All Binder entities in the system and references of each entity in each process are registered in the driver; the driver must record the many-to-one relationship between the Binder references-> entities; find the corresponding entities for th

Android developers may have some experience, early in the beginning, the work is mainly to achieve a variety of UI interface, as well as the implementation of the business logic of the application. At this stage, we will gradually become familiar with the view system, gradually learn to achieve a variety of interface and animation effects. Later, when we want to learn more about Android, such as the start-up process of Android four components, AMS, PMS and so on, will encounter a thing called

To understand the Android code, first understand the binder mechanism. The binder mechanism is also an elusive piece of Android, documenting the important concepts and implementations of binder as a memo.

I will upload my new book "self-writing processor" (not published yet). Today is the tenth article. I try to write it every Thursday. This chapter describes how to implement the openmips processor for teaching. This chapter provides a blueprint for the openmips System for the tutorial version. First, it introduces the design objectives of the system. It details the 5-level pipelines implemented by the openmips processor program. Section 3.2 describe

Some topics The first is the original intention of this paper. I've had a design blueprint for Zend Engine 2.0 for some time (now you can also go to the address in resources to download it back to see), And then there's the urge to write a comment--because the document describes the next generation of PHP as a language that is more in line with existing object-oriented development habits, at least by being given more object-oriented features. But the

4 Binder Protocol The basic format of the Binder protocol is (command + data). The ioctl (fd, cmd, arg) function is used for interaction. The command is carried by the cmd parameter, and the data is carried by the arg parameter, which varies with the cmd parameter. The following table lists all commands and their corresponding data: Table 2 Binder communication c

resource, other processes also access the resource. Therefore, it is primarily used as a means of synchronization between processes and between different threads within the same process.6. signal : Not for information exchange, more suitable for process interrupt control, such as illegal memory access, kill a process, etc.;The kernel of Android is also based on the Linux kernel, why not directly adopt the Linux existing process IPC program, is not the Linux community so many outstanding people

In Android systems, each application is composed of multiple activity and service parts, and these activity and service are likely to be executed in the same processing, in addition, can also be performed in different processes.And then. How does activity or service communicate in the same process?
