Android 支持 v7 TestActivity 的 ClassNotFoundException

Question

我刚刚收到了一个应用程序的崩溃报告。我现在没有完整的堆栈跟踪，但它来自 ActivityLoader.performLaunchActivity。

它试图启动的 class 是 android.support.v7.widget.TestActivity。我当然从来没有尝试在我的应用程序的任何地方加载这个 activity 。

该设备是 Samsung Galaxy Nexus 运行 4.1.1 root。堆栈跟踪对我来说看起来很正常（没有 xposed 或类似的东西）。

有人见过这样的东西吗？

编辑： 这是堆栈跟踪

Answer 1

在 Android issue tracker 中发布后，我收到回复说这是 Gradle 的一个问题，该问题已经解决，并且会反映在支持库中重新更新。

Answer 2

今天早上，我的 BugTracker 系统在几秒钟内收到了几个设备的相同异常

Google Nexus 5 与 Android 4.4.2
Galaxy Nexus Android 4.1.1

看起来有人提取了 APK 并安装在某些模拟器中（我怀疑这也是因为报告的屏幕尺寸是 480x800，这不是 nexus 5 的屏幕尺寸。

所以我认为这不是真正的异常（或者至少是我们的应用程序抛出的异常），而是某人所做的一些测试。

收到的异常是
