1.呼叫播放器播放本地視訊

錯誤演示：

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(Environment.getExternalStorageDirectory() + "/1.mp4"), "video/*");
startActivity(intent);

正確演示：

Intent intent = new Intent(Intent.ACTION_VIEW);
String path = Environment.getExternalStorageDirectory
 
().getPath()+ "/1.mp4";//該路徑可以自定義
File file = new File(path);
Uri uri = Uri.fromFile(file);
intent.setDataAndType(uri, "video/*");
startActivity(intent);

2.呼叫播放器播放網路視訊

String url = "http://www.baidu.com/1.mp4";//示例，實際填你的網路視訊連結
String extension = MimeTypeMap.getFileExtensionFromUrl(url);
String mimeType = MimeTypeMap.getSingleton
 
().getMimeTypeFromExtension(extension);
Intent mediaIntent = new Intent(Intent.ACTION_VIEW);
mediaIntent.setDataAndType(Uri.parse(url), mimeType);
startActivity(mediaIntent);
