What is Content providers in Android SDK?

Content providers are a crucial component of the Android SDK that enable applications to share data with each other securely. They provide a standard interface for connecting to data sources, whether it be a database, file system, or any other type of data storage. By using content providers, apps can manage shared data in a consistent way while maintaining data security and integrity.

Content providers are often used for accessing shared data, such as contacts, images, or even custom data between apps or within an app itself. They follow a set of predefined methods to perform operations such as querying, inserting, updating, or deleting data.
