Dear Hackborn: The Log show nothing. The program I wrote is not an application with activity, more like a system process. I put my code to the android source code directory and then make the android to get my jar file. Then I push my jar file to emulator's system directory, and launch it . This can make my code do something special, but not include force emulator to sleep.
