Messenger and handler for service and client interaction.The server establishes the Messenger object by onbind the server Messenger object to the client by placing it in Ibind, so that the client can get the server Messenger object and use the Server Messenger object to send the message to the service end.After the client connection on the server side, you can establish a client Messenger object, the clien

user experience is better. Remote services are used between applications within the Android system. It can be programmed to operate through interfaces that are defined and exposed by itself. The client establishes a connection to the service object and invokes the service through that connection. The connection is established by calling the Context.bindservice

provides the getservice () method to the client, which can be used to obtain the current instance of the LocalService. This allows the client to call public methods in the service. For example, a client can call the getrandomnumber () method of the server. The following activity code binds the LocalService and calls the getrandomnumber () method of the service when you click a button: Public class bindinga

The Android service is something that runs in the background, with the same level of activity. Since the service is running in the background services, then it is not visible, there is no interface of things. You can start a service to play music, or log changes in the location of your geographic information, or start

Android learning _ Service, android_service Description: one of the modules of the Service application can be seen from the official documents. When an application needs to perform operations that require long running time (processing time-consuming logic in the background ), in addition, you do not need to interact with users. In this case, you can use services

application and other applications to execute actions and generate events. Using intent, You can activate three core components of the Android app: Activity, service, and broadcast receiver. Intent can be divided into explicit intent and implicit intent: 1 ). explicit intent: Call intent. setcomponent () or intent. the setclass () method specifies the component name or the intent of the class object as the

This article focuses on some of the basics of getting Started with Android service and wants to take you to the door of Android Service.1. What is a serviceThe service is a solution in Android that runs in the background of the pr

Now, to create an application, you need to push the notification to the client. I thought of using c2dm. However, the test was not very reliable and the efficiency was not high. But the occasional opportunity to find this site: http://www.push-notification.org/index.php First, we need to declare that many Android apps in China now have the push notification function, but most of them arePull ModeThat is, the client actively requests data from the ser

Life cycle of Android serviceManaging the Lifecycle of a ServiceThe life cycle of a service, from the time it is created, to the time it is destroyed, can have two different paths:A started serviceThe service that is opened is created by calling StartService () from another component.This service can run indefinitely,

implementation. The implementation of the method is completed in the subjectimpl class, the proxy class implements forwarding some method calls to the subjectimpl class. When the client accesses the client through a unified subject object, the forwarding is actually completed through the proxy class. In this way, interface access and interface implementation will be isolated, and only through the basic interface class subject for interaction, thus reducing the design coupling. The following fig

activity, and the service provider activity should meet the conditions. Then it is about the Android system. It is responsible for identifying qualified activity service providers and giving intent to the activity service providers. Then, this acitivity performs corresponding operations based on the remaining informat

The main functions of the service are as follows:A. perform an operation that requires a long time to run. This operation does not interact with users, such as network downloads, large file I/O, and complex computing. B. data communication within or between applications. Each Android Application runs in its own dalvik Virtual Machine. One application cannot access the memory information of other application

ServiceWhen the binding service and all clients unbind, the Android system will destroy it (unless it is also turned on by the Onstartcommand () method).Therefore, if your service is a purely binding service, then you do not need to manage its life cycle.However, if you choose to implement the Onstartcommand () callba

When the android init process is initialized, in addition to some necessary initialization of the system, it is to start the service. The service is defined in the init script, so it is necessary to understand how to process the service in init.Struct serviceThe data structure stores
