Best way to get user-defined custom name for an Android device

I have posted this answer before:

Use

String ownerInfo = Settings.Secure.getString(getContentResolver(),
        "lock_screen_owner_info");

Make sure to catch SettingNotFoundException

Update

As of Android 4.4.2 the owner info value is moved to lock screen database,/data/system/locksettings.db, to which 3rd-party apps have no read/write access. That's, there is no reliable way of reading owner info for later Android versions.
