在Android3.2上选择文本时的UnsupportedOperationException (AppCompat 21.0.3)

Question

我只是准备在更新到AppCompat 21.0.3之后发布我的应用程序。在各种模拟器上进行测试时，我发现每当我试图在WebView中选择文本时，Android3.2上就会出现崩溃。

这似乎不会发生在2.3.3或4.0.3模拟器上(在2.3.3上，它选择文本，并允许我触摸复制。在4.0.3中，它显示了操作模式，这也是我在3.2中所期望的)。有人遇到过类似的事吗？是否有任何修复，或者我们必须等待AppCompat更新？

当我试图从工具栏的SearchView中选择文本时，也会发生同样的情况。

编辑：仍在AppCompat v22中发生。我目前的解决方案是简单地禁用为受影响的人选择文本，如下所示：

// There is a bug in Android 3.0-3.2 that causes selecting text to crash.
// Temporary fix is to disable long-click/text-selection for API 11-13.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB && Build.VERSION.SDK_INT <= Build.VERSION_CODES.HONEYCOMB_MR2) {
    myWebView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            return true;
        }
    });
    myWebView.setLongClickable(false);
}

这个问题在支持库22.1.0中得到了修正(参见：https://code.google.com/p/android/issues/detail?id=80434)
