@youssefsherif, when you post code don't do a screenshot, do a copy and paste into a code block.  The icon looks like </> when you expand the toolbar when you make a post.  It will open a popup for you to paste your code into.

Just replace the text in the code with the proper object property from the parsed JSON.

Instead of:

m.tile.descriptionText = "This is a description"

You would have:

m.tile.descriptionText = json[2].description

 

json[2] is third entry of json and is an object with several parts:   title, poster, and description.  Just "json" is an even larger object (an roArray) with, in this case, 3 entries each of which is an object itself (an roAssociativeArray).  Array indices start from 0, so in this example json[3] doesn't exist.  There's only json[0], json[1], and json[2].  You need to understand these concepts or you're going to have a tough time with BrightScript.

By "local" do you mean it's part of the channel pkg/zip file?

When you use ParseJason you'll get an object back (or invalid if the JSON isn't valid), so you'd do something like this:

json = ParseJson(ReadAsciifile("pkg:/dir/file.json"))
' check json:
if json <> invalid then
   print json.Count();" entries"
   for i = 0 to json.Count()-1
      print i,"Title is ";json[i].title
   end for
end if

You don't need to do that as you will only get row #3
