Content Providers in Android manage access to a structured set of data and allow applications to share data with each other. They act as an interface to query, insert, update, or delete data. Key Features: Data Sharing: Apps can share data with other apps securely using content providers. Data Sources: They can provide access to SQLite databases, files, or even data from the web. Uniform API: They use a common URI structure and methods for interaction. Methods: query(): Retrieve data. insert(): Add new data. update(): Modify existing data. delete(): Remove data. getType(): Return the MIME type of the data.
