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 does the activity or service in the same process communicate? This is the binder interprocess communication mechanism to be described in this article.We know that the Android system is based on the Linux kernel, while the Linux kernel inherits and is compatible with the rich Unix system interprocess communic

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

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? This is the binder interprocess communication mechanism to be described in this article.We know that the Android system is based on the Linux kernel, while

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

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

What is a binder? Binder is a type of IPC. Do not know IPC? Google, the omnipotent Google.In Linux, we know that resources are allocated and managed by processes. Processes run in independent spaces, which are closed and independent from each other. Then the problem arises. In a complicated operating system, what should we do if tasks need to be completed collaboratively between processes? This must inv

Binder is used to complete interprocess communication (IPC), that is, multiple processes are "not" together, from the thread point of view,thebinder driver code runs in the kernel state, the client program calls binders are done through system calls. Binder is an architecture that provides a server-side interface,binder driver, and client interface three module

Windows, Mac OS, Android also has "binder" subsystem. Linux has sockets, FIFO, shared memory and other mechanisms, which are not very good for the application layer. Kdbus attempts to create a mechanism that is similar to other systems for Linux.D-bus is the closest approach to this standard on Linux. Pros:

We know that in Android, every application runs in a separate process, which also guarantees that when one of the programs has an exception, it does not affect the normal functioning of another application. In many cases, we work with the service of various systems, and it is clear that the program we write is definitely not the same process as the system service, but how do they communicate? Binder is one of the ways in which an inter-process communi

RPC (IPC) in Android is implemented by the binder component. Although we use more aidl, we will not directly use binder, however, it can help you better understand aidl and the principles and mechanisms of Android.Binder Architecture Similar to the architecture of other android components, the binder is also composed of Java-layer encapsulation, JNI, libbinder, a

PrefaceIn the ServiceManager of Binder source analysis, we introduce the process of using binder to communicate, that is, after ServiceManager registers itself as "administrator", it is responsible for the add operation of other service, or other client's get operations. In this process, there are some interfaces we do not have in-depth analysis, such as: 1. Open Binde
