Thanks Frank, I found when setting the property the system will check the calling ID and refused my access. That should be the reason, thanks again.

( better android-platform ) But nevertheless: It depends from the name scheme of the system property which rights you need. But I assume that this property can only be set by a system app and theirfore your app must be signed with the platform key. Good luck !
