Common lightweight server communication architecture based on mobile phones

1. XML + HTTP

This communication method is widely used in the instant messaging protocol XMPP and other RSS resources such as podcast;

The advantage of this method is that the server business and interface design will be clearer and simpler;

2. JSON + HTTP

One of the most popular and common ways to interact with servers on mobile phones;

The advantage of this method is that it saves more traffic than the first method, but the interface design and parameter transmission are comparatively more troublesome;

3. Protocol buffer + HTTP

Protocol buffer is a cross-language binary transfer protocol of Google;

This method is obviously efficient, but it will introduce external libraries to increase the package size of the android client. It is not especially performance-demanding and generally not used;

4. TCP

This Protocol is often used when we transmit a variety of large files, or where the performance and traffic requirements are high;

5. UDP

As a heartbeat packet transmission protocol, it is the best option (for example, when pushing data to Alibaba Cloud)
