Intent.action_view invalid issue in Nokia XL

When the video was tested today, it was found that the video app list could not pop up in the Nokia XL model.

My Code is:

Intent Intent = new Intent (Intent.action_view);

Intent.setdataandtype (Uri.parse (Videopath), "Video/mp4");

StartActivity (Intent);
Later found the reason, Uri.parse (Videopath) Here is a problem, Videopath is a string type of video path, there is no "file://" file header. So it is not recognized as a file.

workaround : Uri.parse (Videopath) should be changed to Uri.fromfile (New File (Videopath)). Add file://Head, and then use Uri.parse also line, such as Uri.parse ("File://sdcard/download/1.mp4").
