Hi, What I infer from your code is that you haven't added the APN first into the database. You need to first write the APN settings into the database before updating the preferred APN code. The following links will be helpful in making you understand and resolve the issue:

But if you are developing your app for Android versions prior to Android 4.0 then you need not worry. :) I hope this solves your problems.
