ClassNotFound:android.view.ViewStructure with Support Library 26.0.2 - 27.0.0

Question

我看到三星Galaxy S5在Android 4.4.2上出现了崩溃

NoClassDefFoundError: android/view/ViewStructure

自从我将支持库更新到26.0.2以来,这种情况一直在发生.现在它也发生在27.0.0,尽管我预计这些问题已在其中得到解决.在将应用程序提交到Google Play之后不久,我发现Crashlytics发生了一次崩溃(我正在推广给我的一小部分用户).我不知道重现的确切步骤是什么.到目前为止,我已经假设它可能是在应用程序启动时.

相关报道:

java.lang.NoClassDefFoundError:android/graphics/drawable/Icon

ViewDebug.getExportedPropertyMethods java.lang.NoClassDefFound android/graphics/drawable/Icon

我使用的是支持库27.0.0,compileSdkVersion 27,targetSdkVersion 25,buildToolsVersion '26 .0.2',android插件2.3.3,gradle 3.3,Android Studio 3.0.(我猜这个问题与旧版本的gradle和插件无关？...)

我可以在支持库中看到ViewStructure用于:

android.support.design.widget.TextInputLayout 
android.support.design.testutils.ViewStructureImpl

但是,我没有在我的项目中的任何地方使用ViewStructure.

导致此问题的最可能原因是用户不是常规用户,因为"只有在连接了hierarchyviewer/ddm时才会发生这种情况".
