Context in Android refers to the environment or setting in which an application is running. It provides information about the application's state and allows access to application-specific resources and classes. There are two main types of Context in Android:
Application Context
It is tied to the lifecycle of the entire application.
It is a singleton instance that can be accessed via getApplicationContext().
Use Application Context when you need a Context whose lifecycle is separate from the current Context or when passing a Context beyond the scope of an Activity[1][2].
Example: Creating a singleton object for your application that needs a Context[1].
Activity Context
It is tied to the lifecycle of a specific Activity.
It is available within an Activity and should be used when passing a Context in the scope of an Activity or when you need a Context whose lifecycle is attached to the current Context[1][2].
Example: Creating an object whose lifecycle is attached to an Activity[1].
Some key points about Context:
It allows you to access resources, databases, shared preferences, etc.[2]
