What is context in Android?

I don't understand what context is in Android. I know we generally put "this" in the context parameter, but I don't understand what context is or what "this" is doing.

this represents the current object.

So your class is a kind of factory whose role is to build objects on the same model and then you can refer to a newly created object or instance with the keyword this.

An object is an instance of a class in which properties were assigned with fresh values.
