我自己一直在解决这个问题，虽然我没有回答你所有的问题，但我已经找到了一些。
UMP 将其输出写入SharedPreferences 中的一些字符串，概述here。您可以编写一些辅助方法来查询这些字符串，以了解用户给予了何种级别的广告许可或用户是否为 EEA。
-
如何判断用户是否为EEA？可以查看SharedPreferences中的IABTCF_gdprApplies整数，如果为1，则用户为EEA。如果为 0，则用户不是。
-
如何获得同意类型？这部分变得更加复杂。 Google 文档here 概述了个性化和非个性化广告所需的权限。要获得此信息，您需要查看 SharedPreference 中的 4 个字符串：IABTCF_PurposeConsents、IABTCF_PurposeLegitimateInterests、IABTCF_VendorConsents 和 IABTCF_VendorLegitimateInterests。正如其他人所指出的那样，用户几乎不可能实际选择非个性化广告配置，因为他们不仅必须选择“在设备上存储信息”，而且还必须滚动浏览数百个非按字母顺序组织的供应商才能找到并选择“Google”（这些字符串中的供应商 ID 为 755）。这意味着出于所有实际目的，他们要么选择个性化广告（全部同意），要么拥有一个不错的无广告应用程序，而无需支付任何费用。您至少可以使用这些检查来设置付费墙、禁用云功能或以其他方式处理您认为合适的情况。
我做了一些辅助方法来查找这些状态。
