我自己一直在解决这个问题，虽然我没有你所有问题的答案，但我已经找到了一些。
UMP 将其输出写入此处SharedPreferences概述的某些字符串。您可以编写一些辅助方法来查询这些字符串，以查明用户给予的广告许可级别或用户是否是 EEA。
如何检查用户是否是 EEA？您可以检查IABTCF_gdprAppliesSharedPreferences 中的整数，如果它是 1，则用户是 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。此处的 Google 文档概述了个性化和非个性化广告所需的权限。为此，您需要查看 SharedPreference 中的 4 个字符串：IABTCF_PurposeConsents、、IABTCF_PurposeLegitimateInterests和IABTCF_VendorConsentsIABTCF_VendorLegitimateInterests. 正如其他人所指出的，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字母组织的供应商来查找并选择“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，他们无需支付任何费用。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找到这些状态。
