Default Carrier Config App ========================== This app works as part of com.android.phone.CarrierConfigLoader to configure telephony features based on the subscriber's network. It replaced many XML resource overlays in frameworks/base and frameworks/opt/telephony. The current framework allows per-network configuration that uses CarrierIdentifier objects, rather than just mcc/mnc. This app uses a CarrierIdentifier to read the appropriate config snippets from the assets folder. If you make changes to the XML files, run the unit tests to ensure they can still be parsed: runtest carrierconfig-unit
