trojan 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

Tags: Android AR for SP art problem code: Ad BS =============== Problem description ==================== Recently I saw this sentence in a book: "A binder server is actually a binder Class Object. 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

Model binder is very simple in Asp.net MVC. Simply put, the Action Method in your Controller requires parameter data. The parameter data is contained in the HTTP request, Including values in the form and parameters in the URL. 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

It is simple to understand that an application can have multiple processes, but the need for data exchange requires IPC, or data exchan

Before writing this article, I have been thinking about these issues: Question 1: Why do I need IPC? Question 2: What is binder? Question 3: What is aidl? Question 4: What are the differences and connections between IPC and activity intent, broadcast, content provider, and service? If you can easily answer all the questions, congratulations! You have learned to answer the question ^-^. The answer is as follows: 1. Why do I need IPC? IPC refers to inte

The communication mechanism of the Binder is simple, but some problems have been encountered in the use process. Finally, we have solved the problem. Here we will summarize the problems and share them with you: 1. To use Binder for communication, first define the interface, and then implement the BnInterface *** on the server and the client BpInterface ***. In the end, one is to unpackage the parameters, a

Binder communication mechanism is simple, but in the use of the process encountered a number of problems, finally resolved, in this summary, together to share with you: 1, to use binder communication, first to define the interface, and then implement the server bninterface*** and client bpinterface***, after all, one is to unpack the parameters, one is to package the parameters. 2, the server should be able
