How to open activity from extension?

As the title states, how would I open an activity that is built into my extension from my extension and then open the screen that opened my activity with a start value?

Example:

public static class MyNewActivity extends Activity

Found my solution for opening the activity:

Intent i = new Intent(context.getApplicationContext(), MyNewActivity.class);  
context.startActivity(i);

Hi @KodedScorpius
Sounds good that you found the solution yourself.
But I would like to share something with you:
