Android client-server interaction login example, android example
Today, I learned how the android client interacts with the server, and found that it is actually a bit similar to the web. Then I found a logon example on the Internet based on IntentService.

Client: tsocketconnection and server: scktsrvr-compressed data transmission solution
I have been using socketconnection and the server to transmit data in a three-tier database, and I have never noticed data transmission between them. I just thought about it, and it's a matter of network, some time ago, demos/DAS/intrcpt was found in demos in Delphi. DPR example
this method is very short. In fact, it is just a simple package of the PHP fclose () function. The specific implementation code is as follows:
public function close(){fputs($this->fp,"QUITn");fclose($this->fp);}
The above method sends a "QUIT" command to the POP3 server, which causes immediate interruption of the server and client programs. In ad

to abort the session. If the client program simply hangs, the server "throws" a violation.As you can see here we have taken the same steps to ensure that the network resources represented by the socket are properly cleared, and this is done with a try-finally block.The socket establishes a "private" connection that lasts until it is explicitly disconnected (the
connection is established, then perform logical processing.
Netty can manage multiple ports at the same time and can use the NIO client model, which is necessary for the RPC service.
Netty can process TCP Socket and UDP Socket.
In the process of reading and writing messages, ByteBuffer needs to be used in large quantities. Netty optimizes and abstracts ByteBuffer in terms of performance and ease of use.
