communication between the client and the service:

Eclipse will automatically create the interface IService for the Service[2] The Client connects to the Service, connects to the Stub exposed to the Client by IService, and obtains the stub object. In other words, the Service provides services to the client through the Stub in the in

Note: In the code above, we pass the basic data type. for basic data types, such as Int and String, you can directly read the data as above, however, if a complex object is sent, the object must implement the Serializable or Parcelable interface.For example, we define a SendData object as the passing object, which implements the Parcelable interface:
public class SendData implements Parcelable{ int id; String content; public int getId
The Art of net unit testingOpening : Previous we learned basic unit Testing Basics and introductory examples. But how do we write tests if the method we're testing depends on an external resource, such as a file system, a database, a Web service, or something that's hard to control? To solve these problems, we need to create test stubs , pseudo-objects , and mock objects . In this article we will begin to touch on these core technologies, using stubs to break dependencies, use mock objects for i

Theoretically, we can still use other protocols, but HTTP is currently the most widely used.What does a Web Service Application look like?OK, you have a concept about what Web service is, and you may be expected to write WEV service immediately. before you do this, you may be like what kind of structure of the web service-based application is. If you have written a CORBA or RMI, this structure will look like
First, you should know that although t

What does the Web Service application look like?
OK, now that you have a concept of what a Web service is, you may be expected to start writing Wev service immediately. Before you do this, you might be like the structure of a web-based service application
I have finally translated it into Chinese, but I don't know much about it.Generate a chart from the GT-ITM topology Generator

The GT-ITM topology generator can create a flat random chart and two hierarchical charts, N-level and transit-stub. let's take a look at the example on the homepage Daniel Zappala (in fact this hyperlink is useless ). also look at some documents in the directory under the GT-ITM dir
AsInterface parsing in Binder, binderasinterface
When AIDL is used for communication, an asInterface function is generated in Stub class. The example in Android development art exploration is analyzed. The source code of the asInterface function is:

A remote object must include at least 4 class files: The remote object, the interface of the remote object, the stub of the object that implements the remote interface, and the 4 class files for the skeleton of the object.
At least 10 classes are included in the EJB:
Bean class, specific app server Bean implementation class, Bean's remote interface, specific app server remote interface implementation class, specific app server remote interface imple
