Several friends tried to hook the ioctl of system_process to intercept the IPC communication of the system. The disadvantage of this solution is that it is too low-layer. After successful interception, it is quite troublesome to parse the communication data. in addition, there are also a bunch of compatibility issues. Due to different Android
If you only use services locally in an application and do not need to work across processes, You can implement your own binder class, use it to directly provide your client with the ability to access public methods in the service.
Note:Generally, the client and server only work in the same application and process. For example, for an application that needs to play music well, you need to bind the music playing service working in the background to an a
Binder mechanism is An important means of cross-process communication in Android system. the interaction betweenService and Activity is used in this mechanism. To this end, I have written a small service case, in order to facilitate a better understanding of binder communication mechanism. Service Code: Public classMyServiceextendsService { Public Booleanflag=true; intcount; //Instantiate a binderServicebi
I. Introduction to the messenger of communication between Android processes(1) Introduction :usually a talk between the process of communication, we will think of aidl, in fact, Messenger and Aidl function, can carry out inter-process communication. It is a message-based interprocess communication, just like a sub-thread and a UI thread sending a message, isn't it simple to write a aidl file, or is it a
In fact, there are not many Messenger actually used in actual use, but the examiner still wants to examine your basic skills during the interview. Now let's take a look at the use cases of Messenger. If you need your Service to communicate with a remote thread, you can use a Messenger interface for your Service. This technology allows you to perform inter-process

First, let's take a look at the sequence chart for running the android binder system:
(This figure is from Google Search)
From the time sequence diagram, the entire android binder system is still somewhat complicated, but careful analysis may find that the operating mechanism of the entire android binder seems to be similar to a common system architectu

1. Messager Interaction Structure and Message Type
In the previous article, Messeger is the meaning of a messenger. As the name suggests, Messeger is used to notify and receive messages between View and ViewModel and between ViewModel and ViewModel.
The Messenger class is used for application communicatio
1. What is binder?
Intuitively, Binder is a class in Android that inherits the IBinder interface
From the perspective of IPC (inter-process communication, interprocess communication), Binder is a cross-process communication in Android, and Binder can be understood as a virtual physical device whose device driv
Service Use binding:There are two messengers that define a service side, Smessenger = new Messenger (new Handler () {});Get the client's message in this messenger, get the messenger Cmessenger of the client in the received message,Sending a message to a client is a message sent through the client Messenger Cmessenger.C
If you need to communicate between different processes, you can use Messenger in the Service to implement communication in the process.
If this method is used, the Service needs to define a Handler object (responsible for responding to the Message sent from the client ).
Messenger can share an IBinder object with the client. The client sends a Message to the Service through this IBinder object, and the Hand
If you run a Full-screen program, such as PPT, MSN Messenger can transform your work status to "busy" and block the pop-up notification window. The user clicks the Action menu in the main window of Messenger, point to options, on the Personal Information tab, locate my status, select the check box to display my status as busy and block notifications when I run a full-screen program, such as a slide show. ”
Read a lot of articles on the internet on binder, but I still want to record their own mental journey, some are following the footsteps of others to appreciate the steep scenery, some of their own alone into the code deep salvage of the harvest. I'm not sure I'm all over it, but I'm more worried about the way I'm going to be at a two-month time. The best way to verify and retain them is to write them down and read them back in a few months to see if t
model receives parameter issuesThe general answer is the solution I said above, which seems to be not what I want.Try to think for a moment.The standard HTTP request is received when, for MVC, he is just a form or a querystring (if you understand the error, please correct), then how does the MVC framework do to bind a form to a model?Why did the corresponding field in HttpContext.Request.Form complete the string concatenation?Why is the assignment of the form and the model different? Can I use
Currently, many network management software are capable of transmitting information on the network in real time. Although some network communication software are powerful, some software can not only transmit text information, but also binary files. However, they all have an insurmountable disadvantage, that is, distribution is difficult. Both Computers of information transmission must install the client and server software of the communication software, information can be transmitted only when t
No need for aidl or complex contentprovider, and no need to sharedpreferences or share storage files!Just the simple Messenger, which is also known as the Messenger, through which you can pass a message object in a different process, put the data that we need to pass in the message and you can communicate and pass data across processes. Nonsense not much to say, directly on the code.The first is the service

Preface:
Activity, Service, BroadcastReceiver, and Content Provider are four application components of Android. These components that constitute a complete application can be in the same process or not in the same process, when these components are not in the same Process and data interaction is required, an Inter-Process Communication mechanism (IPC) is required, the
