Re: [android-developers] can I get system service in a my personal service?
Make sure that code is run AFTER onCreate() is called. It isn't clear where
it runs, but the Service class is only fully function from onCreate() to
onDestroy(); you should not use Context methods like this in the constructr.

Re: [android-developers] can I get system service in a my personal service?
Thanks for the reply, I uses the permission as:
I had test the code TelephonyManager tel =
(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE) in an activity
and it works well.

Maybe permission in AndroidManifest.xml is required? On TelephoneManeger
website is information: "Note that acess to some telephony information is
permission-protected. Your application cannot access the protected
information unless it has the appropriate permissions declared in its
manifest file. Where permissions apply, they are noted in the the methods
through which you access the protected information."
