| <p>A mobile operator may wish to exclude specific network types from the |
| total data usage calculated by a device. For example, network traffic |
| over an MMS APN may be “zero-rated” by a mobile operator. To support |
| this, the set of network types used to calculate total data usage can |
| be configured through the <code>config_data_usage_network_types</code> resource |
| at build time.</p> |
| <p>Some mobile radio implementations may have unique Linux network |
| interfaces for each active APN, while other radios may force multiple |
| APNs to coexist on a single interface. Android can collect network |
| statistics from both designs, but <code>config_data_usage_network_types</code> is |
| not be effective at excluding APNs forced to coexist on a single |
| interface.</p> |
