My channel does have a deep linking/search feed that has been approved (a couple years ago), but I'm having trouble figuring out the right URL to bring up a specific program or episode.
An example url I'm using would be:
http://[my device IP]:8060/launch/[my published channel ID]?mediaType=series&contentID=[name-of-series]
And I run this command:
curl -d '' 'http://[my device IP]:8060/launch/[my published channel ID]?mediaType=series&contentID=[name-of-series]'
On my device, my channel DOES launch, but it does not launch that specific series-- it just brings up my channel's home screen. I have also tried this with a specific episode, replacing mediaType with 'episode', and contentID with the ID of that episode, but have the same result.
From the docs at https://sdkdocs.roku.com/display/sdkdoc/Deep+Linking, is your channel looking for args[contentID] and args[mediaType] and using it to change it's behavior? Can you add logging code to show those in the Brightscript console to make sure they're what you expect?
