java.lang.IllegalStateException 仅在 Android TV 设备上崩溃

Question

我只在 Android TV 设备上看到了很多以下崩溃：

由于运行该应用的 Android TV 设备很多，因此崩溃仍然很少见。堆栈跟踪确实表明了任何应用程序的源代码，所以我现在对崩溃一无所知。

我想知道是否有人可以对这次崩溃有所了解，为我指明寻找罪魁祸首的正确方向。

以下图表显示了发生此崩溃的设备：

我不确定您使用什么日志系统来聚合崩溃，但如果您能够查看它的单个实例，IllegalStateException 应该会告诉您方法名称、视图类型和 ID正在发生。

如果这对您不可用，您需要在 XML 文件中查找 android:onClick 的实例。 AppCompatViewInflater 使用反射来找到触发的方法，但这是懒惰的，因为反射很昂贵。换句话说，您将在 XML 布局中拥有类似 android:onClick="handleMyClick" 的内容。当用户触发点击时，AppCompatViewInflater 会尝试使用给定的 Context 查找 handleMyClick(view) 方法，遍历任何 ContextWrappers 直到找到匹配的方法。如果它没有找到匹配的，它会抛出你看到的异常。

最有可能的罪魁祸首是有一个适用于移动设备的 Activity 实现了在 XML 布局中声明的 onClick 方法，而适用于电视的 Activity 没有。另一种选择是具有 onClick 属性的视图只能通过 dpad 轻松/明显地访问。
