I'm trying to understand the details of the ConnectivityManager. I noticed there are methods setNetworkPreference() and getNetworkPreference(), but there are no details in the [documentation](http://developer.android.com/reference/android/net/ConnectivityManager.html#getNetworkPreference%28%29) about how they should be used, except that they accept/return an integer, respectively. There is also a constant called DEFAULT\_NETWORK\_PREFERENCE, but that doesn't really provide many hints. Any ideas?

Thanks in advance!
