What is the role and purpose of the Content Provider component in Android development?

Content Provider in Android is used for data sharing between applications. It provides a standard interface for accessing structured data (such as SQLite databases, files, or other storage) and manages access security.

Main tasks of Content Provider:

• Allows one application to read and modify data of another application if permitted.
• Encapsulates data access logic and ensures consistency.
• Used by the system to access shared data, such as contacts, calendar.

Example: an application can use a Content Provider to read user contacts via URI without gaining direct access to the contacts database.

Thus, Content Provider is an abstraction for secure and standardized data exchange between applications in Android.
