Before analyzing the bind mechanism, I found that an article had been explained very clearly and raised a lot of questions.Address: http://my.oschina.net/keeponmoving/blog/64218I. What are the methods of inter-process communication between Linux systems? 1.socket; 2.name pipe name pipe; 3.message queue message queue; 4.singal semaphore; 5.share memory shared; two. What is the way the Java system communicates? 1.socket; 2.name pipe; Iii. What is the mode of communication for Android systems?

The transformation of the application factory leads to the complexity of routing. In a single script application, the application instance is global, so it is easy to use the app. route modifier to define routes. But now the application is created at runtime, an

In fact, after the Init process starts, the ServiceManager process starts much earlier than the zygote because the ServiceManager process service is needed to start the zygote process. ServiceManager is a daemon that maintains the binder communication between the system service and the client.The most common communication mechanism in Android is that Binder,binder
The previous response briefly describes the principle of inter-process transfer of class objects. before talking about parcel, we should first talk about something: ibinder.What is ibinder? First, you must understand that android remote calls (cross-process calls) are implemented through ibinder. The following is a translation of Android development documentation.Ibinder is the basic interface of remote objects and is the core part of the lightweight Remote Call mechanism designed for high perfo
object returned by Service. onBind (). However, if it is a cross-process, it returns a BinderProxy object. Therefore, we can see that the class generated by AIDL has the following judgment:
if (((iin != null) (iin instanceof MyPrinterInterface))) {Log.e(TAG, "we have local interface, so we use it"); return ((MyPrinterInterface) iin);}
This is actually to determine whether the communication is in the same process or across processes, because the object returned by the same process is Ser
the nature of model bindingsThe execution of any controller method is controlled by the Action Invoker component (hereinafter replaced with Invoker). For each action method's arguments, the invoker component gets a model binder object (ModelBuilder). The role of Model Binder involves looking for a possible value (from the HTTP request context) for the action method parameter. Each parameter can be bound to

The factory function returns the instance of the application created, but note that applications created using the factory function in the current state are incomplete because they do not have a Routing and custom error page handler. This is the subject of the next section.

Therefore, as soon as possible to master JavaScript scripting language programming method is the growing concern of our customers.
One, what is JavaScript
JavaScript is a scripting language that is object-based (object) and event-driven (driven) and has a secure perform
signature to be able.The Android system allocates a separate virtual machine for each process, and different virtual machines have different address spaces on memory allocations, which results in multiple replicas of different virtual machines accessing objects of the same class.Using multiple processes can cause the following problems:
Static variables and single-instance invalidation
