Android Support Library Build v26.X.X Build Error: Attribute “fontFamily” already defined with incompatible format

Question

我将我的支持构建库从 25.4.0 更新到 26.x.x，我得到

AGPBI: {"kind":"error","text":"Original attribute defined here.","sources":[{"file":"/Users/me/AndroidStudioProjects/Mail/mail/build/intermediates/res/merged/dev/debug/values/values.xml","position":{"startLine":40}}],"original":"","tool":"AAPT"}
/Users/me/AndroidStudioProjects/Mail/mail/build/intermediates/res/merged/dev/debug/values/values.xml:373: error: Attribute "fontFamily" already defined with incompatible format.
/Users/me/AndroidStudioProjects/Mail/mail/build/intermediates/res/merged/dev/debug/values/values.xml:41: Original attribute defined here.

我确实清理了项目->重建，使工作室无效并重新启动工作室，从 android:fontFamily 中删除前缀 android（现在项目中只有 fontFamily），从其他库中排除模块（存在冲突） .

我的styles.xml:

如果为了正确的答案我应该给你更多的信息，告诉我。

Answer 1

我发现支持库版本不正确的库。我在其中排除了支持库组（示例 this）（或者我可以删除该库或更新它），但它对我不起作用，我更新了库和（但我认为排除也应该有效）我的项目建成了。

问题：
抛出错误的库如下所示：
我的日志没有向我显示问题出在哪里（间接地，在生成的文件中提到了 roboto）。

决定：
1）您可以排除抛出错误的组：
2) 或更新：

希望我的回答对大家有所帮助。
