Android unity plugin

I wonder if its possible to start activity directly from C# code

I dont mean getting object of a class but actually staqrting Activity class with the life cycle

Something equivalent to java code

Intent intent = new Intent(context,some_activity.class);

Application.OpenURL( “tel://5555551212” ) should work as well if I am not mistaken.

OpenURL( you can put uri of other application like Skype,music player etc)
