I have a GDATA link that I want to use in my App. This link contains a playlist and I want that playlist to be displayed in a ListView. The user will then select the video he/she wants and will then be able to play it in side the app using the local Youtube App.
Please point me to a tutorial that is intuitive. I know that the YouTube API page contains all the info, but I can make heads or tails of it.
I hope this will give you an idea try this (just a sample) and if you have better solutions pls let me know too.
