在全屏webview nokia x中输入视频时出现NullPointerException

Question

嗨,我在过去两天搜索此问题的解决方法,但我仍然没有得到任何解决方案.在webview我正在播放YouTube视频时,我点击它时视频工作正常,但如果我点击Full Screen图标,应用程序崩溃时出现以下错误.我试图重写onShowCustomeView的WebCromeClient,但它没有工作.我尝试了WebView和HTML5 <video>线程的所有解决方案.解决方案适用于Android手机我在Lg g2和xperia p和nexus 7上测试过,但在诺基亚x上它仍然崩溃.有什么方法可以阻止视频播放全屏或播放.

看看这个

重写该方法以返回一个非空 View 对象（例如，布局中的虚假 0x0 View）并查看是否仍然崩溃

         @Override
         public View getVideoLoadingProgressView() { 
           FrameLayout frameLayout = new FrameLayout(getSherlockActivity());    
           frameLayout.setLayoutParams(new LayoutParams( LayoutParams.MATCH_PARENT,    
          LayoutParams.MATCH_PARENT));
           return frameLayout;
         }
