Which part of the Android system provides data exchange between your application and other applications?

In Android, a component called Content Provider is used for data sharing between applications. It provides a standard interface for data access, allowing applications to read and write data of other applications while respecting access rights.

Content Provider manages structured data and implements methods for CRUD operations (create, read, update, delete). The ContentResolver class is used to interact with it.

An example of using a Content Provider is accessing the user's contacts via ContactsContract.
