My information is a few years old, but at the time I was writing a VOIP app and ran into a similar issue. The problem I faced is that when the screen goes off, the WiFi goes into a low power mode called power save polling (PSP), where the WiFi is still active, but latency is very high (which kills a VOIP app). As in your case, none of the solutions you tried worked other than keeping the screen on. The best I could do was set the screen color to black, and dimmed the screen to it's lowest setting.
PSP mode is discussed here: http://code.google.com/p/android/issues/detail?id=9781. Your case seems slightly different in that the TCP connection is actually closed. This sounds like a device specific problem, or a particular incompatibility between your device and router. Have you tried a different router to see if it helps? Also, if it is the PSP issue, I recall it being fixed in some custom ROM (sorry, I don't recall where anymore). Hope this helps, Dirk -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
