Android receives and sends text messages1. Android sends text messagesThe android API provides the smsmanager class for text message processing. The sendtextmessage (Num, null, content, pend, null) function is to sendText message method.

Why do Android apps use MulticastSocket to listen for multicast? Why do they connect to different routes and run on different mobile phones? Some of them cannot receive multicast messages. ---------------------------!!

1: Android SMS sending can be simulated in the simulator. For example, if the ID of the first simulator is 5554, Run cmd Telnet local host 5554 Enter help to see many functional commands used in simulators.
