Hi Weber: I have met this problem before .First you should make sure that you have configed the "power manage function" and you kernel driver fully support it .A few days before,our team suffered this ,because we do not fully support it .When an input action happening, Android will check if screen is on and decide send this MSG to system or not .And we change the source code of java ,and it works . Good luck! fanday 2009/12/2 Michael Trimarchi <trimar...@gandalf.sssup.it>
