But it does. As I said, it sends a "FIN" packet - that's a request to close the connection. The server responds with an ACK and.a FIN of its own which Android ACKs. This is the textbook-standard way to close a TCP connection, and it's initiated by Android when the display goes off. We watch it all on our network sniffers and it's 100% reliable and repeatable. The Android device does *not* send a FIN packet as long as the display stays on, no matter how long it stays on. -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
