| 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. per-network configuration files live in assets |
| folder. Two ways to configure per-network configuration. Preferred way is |
| carrier_config_carrierid_<carrierid>_<carriername>.xml |
| AOSP carrier ID assignments can be found at |
| https://android.googlesource.com/platform/packages/providers/TelephonyProvider/+/master/assets/latest_carrier_id/carrier_list.textpb |
| use carrier_config_mccmnc_<mccmnc>.xml only if there is no matching carrier id. |
| |
| 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 |
