Question

我有一个带有一个Activity的应用程序和多个加载某些子视图的片段和一个用于显示HTML文件的WebView。

WebViews位于片段布局中。现在，当MainActivity扩展 AppCompatActivity 时，应用程序会长按（突出显示文本）而崩溃，但使用 ActionBarActivity 应用程序适用，并显示上下文菜单。

我不知道为什么会这样，但我会感激任何指示。

这是我得到的日志：

崩溃的其余部分是（在问题中添加太久了）here

崩溃发生是因为我从错误的地址得到了什么。我仍在试图弄清楚该参考是什么。

WebView长按崩溃与AppCompatActivity崩溃，但与ActionBarActivity一起工作正常。为什么？
