执行此操作时，我没有收到任何错误，但出现了一个对话框，标题为无法播放视频"，并显示消息抱歉，无法播放此视频".有什么想法为什么我的代码无法正常工作吗?
On executing this, I'm not getting any error but I'm getting a dialog box with title "cannot play video" and with message "Sorry, this video can't be played". Any ideas why my code is not working?
推荐答案
首先检查您是否已在清单中添加了INTERNET权限.
First check that you have added INTERNET permission in your manifest.
下一步，检查视频格式的扩展名是什么.
Next check that what is the extension of your video format.
此链接显示了Android手机和哪些文件平板电脑支持，同时提供编解码器和文件扩展名信息.但是，Android应用程序可以使用由任何Android设备提供的媒体编解码器，也可以使用第三方公司开发的其他媒体编解码器.因此，如果要在Android上播放视频，请找到一种多格式的视频播放器或将视频转换为Android兼容的格式.
This link shows what files Android phones and tablets support, with both codec and filename extension information provided. However, an Android application can use media codecs either provided by any Android-powered device, or additional media codecs developed by third-party companies. Therefore, if you want to play videos on Android, find a multi-format video player or convert videos to Android compatible formats.
请参阅以下Android支持的媒体格式链接.
