Get all captured Videos in Android as a list

问题:

I am trying to get all video available in gallery with below code,

 String[] proj = { MediaStore.Video.Media._ID,MediaStore.Video.Media.DATA,MediaStore.Video.Media.DISPLAY_NAME,MediaStore.Video.Media.SIZE };
 videocursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,proj, null,null, null);
int count = videocursor.getCount();

But I always get count = 0, where was I made mistake ?

I also tried

Cursor videocursor = managedQuery(MediaStore.Video.Media.INTERNAL_CONTENT_URI, proj, null, null, null);

Do like this -

String[] proj = { MediaStore.Video.Media.DATA,
                MediaStore.Video.Media._ID, MediaStore.Video.Media.TITLE,
                MediaStore.Video.Media.DISPLAY_NAME,
                MediaStore.Video.Media.MIME_TYPE,
                MediaStore.Video.Media.DURATION,
                MediaStore.Video.Media.SIZE,};

 String orderBy = android.provider.MediaStore.Video.Media.TITLE;

 Cursor videocursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
               proj, null, null, orderBy);

To get the size, you can use

 int count = videocursor.getCount();

EDIT managedQuery() is deprecated
