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

Question

我看到三星 Galaxy S5 和 Android 4.4.2 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。现在它也在 27.0.0 上发生，尽管我预计此类问题已在其中得到解决。在将应用程序提交到 Google Play 后不久，我在 Crashlytics 中看到一次崩溃(我正在向一小部分用户推出)。我不知道重现的确切步骤是什么。到目前为止，我假设它可能是应用程序启动的时间。

相关报道:

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

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

我正在使用支持库 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？...)

我可以看到在支持库中使用了 ViewStructure:

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

但是，我没有在项目的任何地方使用 ViewStructure。

导致此问题的最可能原因是用户不是普通用户，因为这“只有在连接了 hierarchyviewer/ddm 时才会发生。”
