Thanks for the reply, I uses the permission as:
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"
/>
I had test the code TelephonyManager tel =
(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE) in an activity
and it works well.
