This question already has an answer here:
Couldnt explain it better:
"Context allows access to application-specific resources and classes, as well as calls for application-level operations such as launching activities, broadcasting and receiving intents, etc. Context in Android is an interface to global information about an application environment." - From one of the thread in stack overflow".
"Context is context of current state of the application/object.Its an entity that represents various environment data . Context helps the current activity to interact with out side android environment like local files, databases, class loaders associated to the environment, services including system-level services, and more. A Context is a handle to the system . It provides services like resolving resources, obtaining access to databases and preferences, and so on. An android app has activities. It's like a handle to the environment your application is currently running in. The activity object inherits the Context object."
