Android client communication device and method allowing Android client communication device to connect and communicate with server

Abstract

The invention relates to an Android client communication device and a method allowing the Android client communication device to connect and communicate with a server. The method includes: a persistently-connected socket channel is built between a client background and the server, wherein the socket channel is the only connection and communication channel between a client and the server; the client background receives a message pushed by the server through the socket channel; when a client foreground is online, the client background transmits the pushed message to the client foreground in a UNIX system process communication manner, and the client foreground displays the pushed message in an application program; when the client foreground is offline, the client background displays the pushed message through the notification mechanism of a system. The method has the advantages that the back-end server constantly communicates with the client background, the back-end server program does not need to respectively process according to the different conditions of online and offline, and development complexity is lowered greatly.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an Android client communication device and a method for connecting and communicating with a server. Background technique [0002] Android (Android) is an open source smartphone operating system. Due to its free and open nature, it soon became the mobile operating system with the largest market share, providing a strong infrastructure for the development and popularization of the mobile Internet. Various mobile phone applications (Applications or APPs for short) developed based on the Android system provide great convenience for our lives. Generally speaking, mobile phone applications are C / S (client / server) architecture, the client is installed on the user's mobile phone, and the server is on the server of the reference provider. After the application is started, it needs to connect to the Internet, obtain a connection with the server, and go to the server to obtain the late...

Problems solved by technology

[0006] 2) SMS (Push) method: By intercepting SMS messages and analyzing the content of the message to understand the server's command, but this method is generally difficult for users to bear economically, and few products adopt this method

[0011] 1. The problem of keeping the background process alive: the background process used by the mobile client for communication will die due to some reasons such as system recycling and user triggers. If the process dies, the long connection with the background server will be disconnected, and the backend server Real-time messages cannot be pushed to the user's mobile phone

[0012] 2. The problem of switching between online and offline communication methods: the unreasonable architecture leads to separate processing of online and offline push

When the user starts the application, he will request data from the backend server, and at this time the background process can also obtain the data from the server. In order not to cause confusion, both the client and the backend server need to do some switching processing, that is, the application The online and offline situations are distinguished and processed separately, resulting in a more complex architecture and prone to problems
