Question

当我在我的Galaxy Nexus上切换到4.2并且持续使用我的Nexus 4时，这种情况就开始发生了。我的应用程序随机崩溃（软重置）设备，即使没有用户输入也是如此。

这是崩溃前的Logcat：

01-17 12:54:24.960: E/AccessibilityManager(10497): Error during sending EventType: TYPE_WINDOW_CONTENT_CHANGED; EventTime: 151405384; PackageName: com.ntasher.homeconII; MovementGranularity: 0; Action: 0 [ ClassName: android.widget.FrameLayout; Text: []; ContentDescription: null; ItemCount: -1; CurrentItemIndex: -1; IsEnabled: true; IsPassword: false; IsChecked: false; IsFullScreen: false; Scrollable: false; BeforeText: null; FromIndex: -1; ToIndex: -1; ScrollX: -1; ScrollY: -1; MaxScrollX: -1; MaxScrollY: -1; AddedCount: -1; RemovedCount: -1; ParcelableData: null ]; recordCount: 0

之后设备软复位（直接发光到“X”）。

这里发生了什么？是一些未处理的例外吗？我怎么能抓住它？感谢。

您尚未提供任何代码，但我怀疑这是问题所在。

在创建绑定到系统的某个对象时，您正在传递Activity上下文。因此，当您关闭应用程序并且对象停留时，它将成为一个死引用。对不再活着且可见的活动的引用。

在某些地方你会有像以下几行：

SomeClass object = new SomeClass(this); //Or getActivity() or something.

在这里，将Context参数更改为getApplicationContext()（除非该代码正在创建并显示对话框，在这种情况下，请使用“活动”上下文。）

我的应用程序使用AccessibilityManager未处理事件使设备崩溃（Galaxy Nexus和Nexus 4）
