In my app I have list of movies, that updates dynamically. Is it possible when user click on movie item, to start installed Imdb app and to show movie description?
You can try to use
imdb:///name/<nameID>
imdb:///find?q=<search_query>
imdb:///title/<titleID>
as an URI parameter in your intent. For example
startActivity(android.intent.action.VIEW, imdb:///title/<titleID>);
