messenger binder

A lot of people say that the binder is a proxy model, more than the same, can understand the essence of less. This article analyzes Java Layer Binder design objectives from a design perspective, as well as design ideas, design flaws, and thus harness it.For "Bond son" understanding, from the communication point of view, is a way of communication, and socket is no different. Client transact, server-side ontr

Binder is the basis and key of IPC on Android. In most cases, we can see the structure of the client and the server, that is, the server creates a service to provide services to the client, and the client starts communication by binding to the binder object. The specific method for obtaining the binder object is also related to the service call method:1. Usestart

Once this object is created, a hidden thread is started internally. This thread will then receive messages sent by the binder driver ."I have two questions:1: where is

If your service is only used by your own application and does not need to work across processes, You can implement your own binder class so that your client can directly use the public interface method of the service. Note: This only works when the client and service are in the same application and process. This is the case in most cases. for example, this method works well when a music application needs to bind its activity to its own background serv

The modelbinder function is to replace the values and URL parameters in these forms with objects, and then bind these objects To the parameter of the action. I simply drew a picture, which looks more intuitive. In

First look at an Android system startup flowchart:One of the two most important indicators of a process is the initiation of the binder thread pool, which is the ability to process binder interprocess communication. Another is the launch of the handler message loop, which enables the use of the message loop mechanism.1. When did the Systemserver process implement the above two mechanisms? See Code:The

3. Any inter-process communication (Socketpair_binder)Each time the process executes open open file, it will have a structure of file in the kernel to represent it;For each process in the kernel there will be a task_struct representation process, the structure of the body has a files_struct structure, the structure has a fdtble structure, the structure has a struct file **fd,fd is the number of groups, fd[ The handle returned at open] is the file structure of the corresponding files savedTherefo

Today's instant messaging software dazzling, we are familiar with nothing more than Tencent's QQ, Microsoft's MSN Messenger and NetEase's bubble, in terms of user volume, the three should be among the top. But Tencent's QQ and NetEase's bubble did not disclose its client-server communication protocol, which makes it difficult for developers to use this huge user group to open up additional service channels.
