How to Open specific application using intent in android?

Question

I want to open an .ics file & i want to make sure that particular app should do that using intent

Answer 1

For opening another app:

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

Form there the control goes to that app, so if you wanna give some effects, you have to do it in the target app
