Service as one of the four major Android components, the application is very extensive
This article describes one of the common uses of the service: remote service
If you are not aware of the service, it is recommended to read another article I wrote:Android Four components: the most comprehensive analysis in service history

as your mobile device is connected to the development machine via USB, you can start debugging, and you can view and even modify the structure, scripts and styles until you get a bug-free page that behaves perfectly on all devices. When you debug a Web application on your development machine, you can use port reverse forwarding to allow a mobile device to access a website from the development machine via USB. Port reverse forwarding requires the development machine to install Chrome 29 or later
ULog remote log-making Android debugging more convenient and intuitive
After the U8SDK is released, if you use U8SDK for SDK access, debugging is difficult. This is not a problem with the U8SDK, but a common problem in Android development. For Android development, we usually use logcat for debugging. If it is a native

Permission permission
If the service declares the global mandatory access permission in androidmanifest. XML, other references must declare the permission to start, stop or bind the service.
In addition, the Service can protect her IPC method calling through permissions, and ensure that this operation can be performed by calling the checkcallin

I have DIY one Android remote - all open source1. TrialRemember Song Baohua in the "device-driven development specific explanation" put forward a theory "software and hardware infiltrate each other's territory", this proves to be true, the use of the upper-level APP software with simple and simpler hardware design can complete a remote control.

Android Service is divided into two types:
Local Service: called in the same apk
Remote Service: called by another apk
Remote services must be completed using AIDL.What is AIDL?

This example and the next example of remote Service Controller related documents are Remoteservice.java, Iremoteservice.aidl, Iremoteservicecallback.aidl and Isecondary.aidl.

The previously mentioned Service is a Local Service, that is, the Service and Client are in the same process (that is, within the same application), and the Service lifecycle is subject to the process lifecycle. In practical applications, sometimes you want to use the Service as a background Service, not only by the activity in the same process, but also by other processes. In this case, you need to use bindService, that is, the Remote Service method.
Android uses SOAP to call the remote WebService and androidwebservice
In today's applications, the network cannot be used, and the backend must be supported by servers. Currently, the most common call methods are http get and POST methods, which return JSON or XML data. However, there is also a common form of calling WebService. Now we can call WebService data using the simple SOAP Object Access Protocol on
