Android learning _ 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 in the background

Service is one of the four components of Android, which differs from activity in that it has been running in the background without a foreground interface. Once the service is started, he has the same life cycle as the activity.first, create service, define a subclass that inherits the serviceA series of life cycle met

problem with the Socket initialization error. This error occurs because the initialization of the SOKCET is placed in the onCreate of the first Activity.Since the service was used to make the music player, it should be no problem to think of using serivce to handle the Socket. But is there any other way to do it? Since the individual is just touching Android programming, it is not possible to determine thi

1. What is service? The service can be used in multiple applications. For example, when the user starts other activities during multimedia playback, the program must continue playing the video in the background, for example, detecting file changes on the SD card, or record the changes in your location in the background. In short, the service is always stored in t

Bind service can bind application components to local services, or bind services of other applications. In Android, each application runs on In your own virtual machine, each virtual machine corresponds to a process in the Linux kernel. Therefore, you can bind the service of other applications to implement inter-process communication. Binder is a base class for o

this time.Managing the Lifecycle of a Bound 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 choo

First, Android system servicesAndroid offers a lot of system services: such as Activitymanger,powermanger,windowmanger,wifimanger and so on.These services are always available at the beginning of the system startup, and if the app needs to use the appropriate system services (such as getting the status of the current WiFi), it needs to access the system services via binder.For example: Wifimanager Mwifimanager = (wifimanager) context.getsystemservice

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
