hi.At last I fix the problem.
I found that in the logcat
16016 D/MediaScanner( 1033): opendir /system/media/audio/alarms/
Alarm_Rooster_02.ogg/ failed, errno: 20
16017 E/MediaScanner( 1033): Error processing '/system/media/audio/
alarms/Alarm_Rooster_02.ogg/' - skipping
16018 D/MediaScanner( 1033): stat() failed for /system/media/audio/
alarms/Alarm_Rooster_02.ogg/: Not a directory
16019 D/MediaScanner( 1033): stat() failed for /system/media/audio/
alarms/Alarm_Rooster_02.ogg/: Not a directory
16020 D/MediaScanner( 1033): stat() failed for /system/media/audio/
alarms/Alarm_Rooster_02.ogg/: Not a directory
After copying a media dir which contain the needed files to system.
Then the system can bootup ,and I can enjoy the musics.
Thanks
