Android message push is basically implemented in the form of long links. The principle is that the client actively establishes a long TCP link with the server. After the long link is established, the client sends heartbeat packet to the server regularly to keep the link. When there is a message to send, the server can send the message directly to the client through the established long link.

Android can push messages in two ways, one is self-built push platform, but this way is time-consuming and laborious, and the stability and survivability of long links are difficult to guarantee; The other is to directly choose a third-party message push provider such as Twitter. Developers only need to integrate a push message SDK to realize the message push function of Android platform simply and quickly, effectively improving product activity and increasing user retention. In addition, personal push message push also has advantages in the basic performance of message push, such as saving electricity and traffic, long link stability, push rate, security and so on.
