How to open a specific application using intent in android?

Question

I want to open a .ics file and I want to make sure that this application should do this with the intent

Answer 1

To open another application:

Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage("package.name.of.destination.app"); startActivity(LaunchIntent); 

Create a control there for this application, so if you want to give some effects, you have to do it in the target application.
