It is easy to inherit the intentservice class to implement a service of the started type, but if you need the service to execute multiple threads (instead of processing the startup request through the work queue ), then you must inherit the service class to process each intent.
For ease of comparison, in the following example, the implementation code of the

First step: Create a WCF Service
We used the service tag of the typed contract to invoke the WCF service in COM, but this has some limitations because the. NET Framework is required because of the need to register the type, but in many cases the COM client's environment does not have the. NET Framework, For example, in Excel, you need to call a WCF

Using Network Service Discovery, showed you how to discover services that are connected to a local network. however, using Wi-Fi Direct trad; Service Discovery allows you to discover the services of nearby devices directly, without being connected to a network. you can also advertise the services running on your device. these capabilities help you communicate between apps, even when no local network or hot
The most important component services and activities of Android are the communication problems between them. Of course, today we will not study the underlying implementation issues. I will study how to use the upper-layer applications.
First, the activity calls the service
This is relatively basic, and there are two common methods;
First, using intent, this is relatively simple. You can specify the package name and class name to call it. The intent. s

Introduction
Web services are designed to address some of the application heterogeneity problems encountered in large enterprises. However, the Web service itself does not provide a complete solution to resolve the heterogeneity problem. In particular, they are not intended to handle a mismatch between the transport protocols used by the service consumer and the servic
