All about Context: How to Use context? : <p>As a newbie I am trying to make an app thorough watching some tutorials. I am approaching further and getting more and more confused about "Context". About its definition as well as its contribution. Most puzzling part is when to put the "context" as a parameter.</p>

<p>Which types of classes take "context" as parameter?
What can/should I suppose to do with it?</p>
