java.lang.IllegalArgumentException: provider doesn't exist: network

Question

I have compiled an system from AOSP and fastboot it into Nexus 7. I am now trying to write a very simple app to test the location updates through Network provider.

I have a sim card installed and enabled all the settings but I always get the errors shown below. It seems like there is no network provider. But How can I enabled it?? I have been stuck in this for ages and have no clues.(GPS is working fine)

Have you added this to your manifest?

<manifest ... >
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    ...
</manifest>

Also, to be sure you have enable the location update in your phone setting, you can prompt the user to enable it using this method
