Original address: http://blog.csdn.net/universus/article/details/6211589Binder is one of the inter-process communication (IPC) modes of Android systems. The IPC means of interprocess communication already owned by Linux include (Internet process Connection): pipe, Signal (Signal) and Trace (trace), socket (socket), Message queue (message), Shared memory (Share memories) and semaphores (Semaphore). This article details the advantages of binder as the m

In the previous article talking about Service Manager as the path of Binder daemon of the Android interprocess communication (IPC) mechanism, this paper introduces how Service Manager becomes the daemon of binder mechanism. As a daemon, Service Manager's job is, of course, to serve the server and the client. So how does server and client get a Service Manager interface to enjoy the services it provides? Thi

5 Binder statement During the entire Binder communication process, we can find that the Binder exists in the following parts of the system: · Application processes: Server Processes and Client Processes · Binder DRIVER: Server and Client have different expressions · Data Transmission: Since the

This file ends with. tab. The first line shows the name of the Data Attribute. The class name is separated by a tab. The second row shows the data type. Continuous Data is represented by C,

I. Overview of the binder mechanism In Android development, many times we need to use interprocess communication, so-called interprocess communication, to achieve interprocess communication mechanism there are many kinds of, such as socket, pipe, and so on, Android in the way of communication between the main three kinds: 1. Standard Linux Kernel IPC interface; 2. Standard D-bus interface; 3.Binder inte

Overview of the binder mechanismIn Android development, many times we need to use inter-process communication, so-called interprocess communication, the mechanism to achieve inter-process communication, such as sockets, pipes, etc., there are three ways to communicate between processes in Android:1. Standard Linux Kernel IPC interface;2. Standard D-bus interface;3.Binder interface.The

I. Overview of the OutlookRecently to implement the Android registration activity can run the problem, then the result is done, Just can not be declared in the Androidmanifest.xml this activity can run, mainly through cheat system, steal dragon turn Phoenix technology, this knowledge point will be explained in detail, because in the process of studying this problem encountered a lot of knowledge points, of course, the most important is the most fundamental is the Android B Inder mechanism and re

For details about the Binder design idea and Driver layer implementation, refer to: Android Binder Design and Implementation-design. Here we will give a brief introduction. Each Binder entity of the Service is located in the process type of the Service. The Binder entity is represented as binder_node in the driver, and

Android Binder Mechanism introduction, androidbinder Mechanism Some people who have developed Android may have some experience. At the early stage of getting started, their work mainly involves implementing various UI interfaces and implementing the business logic of applications. At this stage, we will gradually become familiar with the View system and learn to implement various interfaces and animation effects. In the future, when we want to learn m

(1) OverviewAndroid's binder Mechanism provides a method for inter-process communication, so that a process can call the functions provided by another process in a way similar to a remote process call. The binder mechanism is provided in both the Java environment and the C/C ++ environment.In the android code, the binder with C/C ++ includes some types and interf

Recently saw a blog, is to talk about the binder principle, before looking at the deep understanding of Android I have seen, at that time do not understand. Feel this also a bit of meaning, looked for a few days, found the more see the more do not understand, and then look at Lao Luo's blog, found also not too understand, now want to according to the book of Things Good comb under binder.The sense inside should be focused on should be Bind_node is the

Binder is an IPC mechanism on Android that is important and difficult to understand. Due to the lack of flexibility and reliability of the standard IPC on Linux, Google has implemented binders based on Openbinder's design and vision.This article simply introduces its implementation and focuses on binder security-related content. Detailed Binder design and impleme

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

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

1. binder communication OverviewBinder communication is a client-server communication structure,1. On the surface, the client directly calls the server by obtaining a proxy interface of the server;2. In fact, the methods defined in the proxy interface correspond one to one with those defined in the server;3. When the client calls a method in a proxy interface, the proxy interface method packs the parameters passed by the client into a Parcel object;4.

BinderBinder as a mechanism for IPC in Android, is used everywhere in Android. Contains three layers (Java, c++/c, driver).The purpose of binder is to implement communication between multiple processes, with data passed between the basic data type, binder type, and this wrapper in parcel.In the C + + tier, use multiple classes to encapsulate:The main classes are: RefBaseAbout reference counting

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
