Design + Code an Android App from Scratch
This video talks about what is context in Android. 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. There are 4 different Context objects in existence, the Activity itself, the Application Context, the Base Context and the raw Context object that the device manufacturer has implemented.
