如何从Android中的.mov文件获取缩略图？

我使用下面的代码来获取JPG和AVI文件的缩略图，但我无法从.mov文件中获取缩略图。如何从Android中的.mov文件获取缩略图？

String[] projection_image = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID, }; 
      String[] projection_video = { MediaStore.Video.Media.DATA, MediaStore.Video.Media._ID, }; 

      File file = new File(viewTag.mFileNode.mName) ; 
      String tempfilePath = file.getPath(); 

      String whereClause_image = MediaStore.Images.Media.DATA + " = '" + tempfilePath + "'"; 
      String whereClause_video = MediaStore.Video.Media.DATA + " = '" + tempfilePath + "'"; 

      ContentResolver cr = getActivity().getContentResolver(); 
      Cursor image_cursor = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection_image, whereClause_image, null, null); 
      Cursor video_cursor = cr.query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, projection_video, whereClause_video, null, null); 

      try { 

       if(image_cursor.moveToFirst()){ 
        long thumID = image_cursor.getLong(image_cursor.getColumnIndex("_ID")); 
        Bitmap bitmap_image = MediaStore.Images.Thumbnails.getThumbnail(getActivity().getContentResolver(), thumID, Images.Thumbnails.MICRO_KIND, null); 

        viewTag.mThumbnail.setImageBitmap(bitmap_image) ; 

       } 

       if(video_cursor.moveToFirst()){ 
        long thumID = video_cursor.getLong(video_cursor.getColumnIndex("_ID")); 
        Bitmap bitmap_video = MediaStore.Video.Thumbnails.getThumbnail(getActivity().getContentResolver(), thumID, Video.Thumbnails.MICRO_KIND, null); 
        viewTag.mThumbnail.setImageBitmap(bitmap_video) ;    
       } 

      } catch (NullPointerException e) { 
       // TODO: handle exception 
       Log.i(TAG, "cursor---NullPointerException"); 

       image_cursor = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection_image, whereClause_image, null, null); 
       video_cursor = cr.query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, projection_video, whereClause_video, null, null); 

      } finally{ 
       image_cursor.close(); 
       video_cursor.close(); 
      }

是否有人知道如何在Android中使用MediaStore摆脱传送文件的缩略图？

我认为不支持在Android .mov文件，请对支持的媒体类型看看这里[支持的媒体格式（http://developer.android.com/guide/appendix/media-formats.html ） – 2014-02-11 06:02:49

Bitmap thumb = ThumbnailUtils.createVideoThumbnail(path, 
    MediaStore.Images.Thumbnails.MINI_KIND);
