如果需要,这是我的DropBox日志

事实上,我甚至不建议在我的网页视图中与HTML5视频进行交互.我猜,用户从页面打开他们,也没有提供互动.此外,我认为尝试禁止用户与其他网页进行交互是一个糟糕的方法(如果我的应用程序可能真的很难).而且,用户对于我的应用程序绝对不会感到温暖的感觉,当他出现崩溃对话框时…
所以我想阻止用户在我的网页视图中与HTML5视频的交互,或者正确地捕获异常(似乎不是很好的方法).最好的方法是什么？

以下是我们的Webview设置,如果需要的话：

webView.getSettings().setJavaScriptEnabled(false);
webView.getSettings().setUserAgentString("Some user agent");
