    return listChildHeader; 
} 

}

любого, что есть решение этого PLS Тил мне об этом

Answer 1

Добавить webview.setWebChromeClient(new WebChromeClient()); и для включения плагинов для вашего видео:

if (Build.VERSION.SDK_INT < 8) { 
     webview.getSettings().setPluginsEnabled(true); 
    } else { 
     webview.getSettings().setPluginState(PluginState.ON); 
    } 

Это сработало для меня. Надеюсь, это поможет.
