在lenovo IdeaPad上的 webview 中加载facebook.com时应用程序崩溃，并出现以下异常
这不是来自我的应用程序，而是系统抛出的异常。
当 facebook 在 lenovo 提供的标准浏览器中加载时，会观察到同样的崩溃。
在我运行应用程序时崩溃之后，没有观察到崩溃并且能够加载 facebook 页面，但这是随机行为，因为我可以在标准浏览器和我的 webview 上多次看到崩溃
这个异常是从我的应用程序中处理的吗？如何 ？
通常onPageFinished()在调用 webview 时会引发此异常，但有时会引发此异常onPageStarted()
以下是logcat日志
