android - Galaxy Nexus 4.0.2 在 WebView.onTouchEvent 上出现异常

Question

我的 ACRA 的挤压报告告诉我，Galaxy Nexus 4.0.2 在我的应用程序中至少出现了 4 次如下所示的异常情况。我怀疑用户在横向的 WebView 上进行了一些多点触控操作(从 ACRA 的报告中得知)，但我不知道为什么会导致这种情况。

我从粉碎报告中看不到与我的代码相关的任何内容。我在应用程序的许多地方使用了 WebView，但不确定哪里出了问题。

我相信用户对此不满意，他/她可能认为我的应用程序设计得很糟糕。有什么我可以做的吗？有人有这个问题吗？任何信息将不胜感激。

Android 的 ITS 上也报告了同样的问题。 WebView 相关修复将在未来版本中推出。截至目前，我们还没有解决办法。

WebView related issues are fixed. Don't know about MapView. Also note that this problem may occur if an application has a touch listener that passes some but not all events down to the ScaleGestureDetector. It's important that ScaleGestureDetector sees the entire stream of events.
