After receiving ,it must click “send” to receive the next message？
No matter how much the sender sends, it will not be printed automatically. It will only be printed once after clicking “send”.

Chat example of #35 is working better than old version: Both Server and client (Android) can send multiple messages, and the messages are received and displayed for the recipient as fast as possible.
