There can be many ways of doing this. What I regularly use, is to have
my own Activity class, say, MyActivity which extends the Activity
class.

All the other activities in my application extend MyActivity instead
of Activity. In Activities, I have a few methods, which I think would
be used by almost all my activities, like firing intents, showing
toasts, dialogs, etc.

So, in MyActivity, you can have a method, startIntent(Class class),
and write these three lines of code here.

Now whenever you need to trigger an intent, just call this method with
the target activity class.
