将运营商 ID 与 CarrierConfig 集成
从 Android 10 开始，运营商配置支持将运营商 ID 用作密钥，从 CarrierService 获取运营商专属配置。

将运营商 ID 与 CarrierConfig 集成具有以下优势：

将每个运营商的所有 MCC/MNC 对整合到一个位置，从而移除重复或不一致的数据。
为每个运营商创建规范标识符并消除歧义。

允许使用单个 ID 标识移动虚拟网络运营商 (MVNO)，而不是将配置作为移动网络运营商 (MNO) 的一部分。

final CarrierConfigManager configManager = (CarrierConfigManager) mContext.getSystemService(Context.CARRIER_CONFIG_SERVICE);

PersistableBundle b = configManager.getConfig();
b.putBoolean(KEY_PREFER_2G_BOOL, false);

b.putBoolean(KEY_DISPLAY_HD_AUDIO_PROPERTY_BOOL, true);
