The last time we talked about how to implement an updatable progress notification, we started a thread to simulate a download task, and then sent a progress message to the UI thread Message Queue according to the task progress, the UI thread updates the UI of the notification based on the progress message. However, in practical applications, we generally run background tasks that are time-consuming, such as upload and download, in the form of services, and update progress notifications are also
This example describes the service usage of the four Android components. Share to everyone for your reference, specific as follows:

To handle this background process, Android introduces the concept of service.
The service that is triggered by the command is implemented through the inheriting class of intentservice, or it can be implemented directly through the inheritance class of the service. In the example of Intentservice, we added the StopService () method to the experiment. In practical application, Intentservice is often used for one-time operation, automatic end of the situation, do not need to stop manual
This example and the activity code for the following local Service Controller are defined in Localserviceactivities.java, as implemented by the Localserviceactivities inner class. The service invoked is LocalService.LocalService can be either a "Started" service or a "Bound" service.A "Bound" service can provide

We have two methods (start and bind) to start a Service. The Service life cycle of each method is different. This post mainly describes start service.
There are only three stages in its lifecycle: onCreate, onStartCommand (replacing the original onStart method), and onDestroy. For example:

RMI and Spring
RMI is a way for the Java platform to implement remote invocation, introducing the Java platform to JDK1.1. "Spring simplifies the RMI model and provides a proxy factory Bean that allows us to assemble our RMI services into our Spring applications like local JavaBean." "Here's one more thing, RMI is a way to implement RPC on the Java platform." Considerations for RMI use
