AndroidOreo字体系列NPE崩溃

然后我在我的活动布局中将它设置在TextView上,如下所示:

这可以在运行Marshmallow的Nexus 5上使用正确的字体呈现TextView(使用支持库).但是当我尝试在具有以下堆栈的Pixel Oreo设备上运行它时崩溃了:

Caused by: android.view.InflateException: Binary XML file line #44: Binary XML file line #44: Error inflating class TextView
Caused by: android.view.InflateException: Binary XML file line #44: Error inflating class TextView

看起来像膨胀字体有些错误,但不能推断出更多.
