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

So hurry up today to write the next article, in fact, things are not many. Hurry to t

Accidentally get a copy of the code on the Erlang Web page ServerI have to say it is very elegant, the document is very good, but I see his scene management in the broadcast algorithm, have to say that the writing is very beautiful, but very low efficiency.Each time the global traversal of all online players in a scene of the toy ID, such an algorithm, I do not know how much a service can prop up the number

description of the intent, passes the intent to the called component, and calls the component. Intent can be used not only between applications, but also between activities/services within the application. Therefore, intent acts as a media intermediary here, providing information about component calls to each other to decouple callers from callers. The function of intent is shown in the SDK as follows: · Start an activity through context. startactivity () javastivity. startactivityforresult; ·

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.

The difference between Service and Activity is:(1) The Service has been running in the background and there is no user interface. (2) once the service is started, it is the same as the activity. H

In a distributed system, in addition to common end-to-end communication, there is also one-to-many broadcast communication. When it comes to broadcast, it may be reminiscent of IP multicast or IP multicast. This is not the topic of this article. This article will talk about TCP-based application layer broadcast. As follows: The rounded rectangle represents a pro

In addition to ibinder, you can also use broadcast receiver for communication between activity and service.Case: send a request to the remote server through the service and dynamically update the master node based on the results returned by the serverProgramUi. The main program can shut down or restart the service in real time. Register a broadcastreceiver in t

I monitored Weibo data through the backend service. After I found that the data was updated, I notified the foreground program and sent the blog data list to the foreground activity.The broadcastreceiver object is used to register a broadcast in the act

If the system only sends one-time broadcast (such as boot), the receiver only recognizes the broadcast once because the system does not send the broadcast any more; in this case, you need to enable the Service (start the service at startup) and continuously listen for change

Broadcast and service are one of Android's four main components.The broadcast here is dynamic and registers itself with a broadcast.The most typical use is to use the power-on broadcast, and then start their own services, that is, in the Android phone to open the boot.Service and broadcastpublic class MyService extends
