嘿伙计们我是Android新手。我在webview中的视频无法在移动设备上播放。但它确实在平板电脑上播放。 会有什么问题？以下是我的代码。请帮帮我。

并且还向我解释了WebViewClient和WebViewChromeClient之间的区别是什么？
答案 0 :(得分：0)
请在您的android清单文件中添加hardwareaccelerated设置为true。 android 3.0+我们必须启用此功能，然后才支持视频。你当然可以使用它们，它们只是具有不同的功能。设置您自己的自定义WebViewClient可以处理onPageFinished，shouldOverrideUrlLoading等，WebChromeClient允许您处理Javascript的alert（）和其他功能。
