Android - Difference between ContentProvider and ContentResolver in android?

To create a complete content provider, both applications should implement complete set of rules that the Content Provider functionality requires.

So, which means that the app A that provides some content has a specific type of URI to provide the content over this URI with the help of ContentProvider.

Now if the app B wants to get the data it should will first use the ContentResolver to resolve the URI of the app A to get the data that the app A's ContentProvider provides.

So the ContentProvider provides the way to query the content that it is allowed to provide to other apps for example, and the ContentResolver is used to resolve the URI of the app that is using the ContentProvider to provide the content on that resolved URI.

Without ContentProvider you cannot provide content to other apps.
Without ContentResolver you cannot access content from other apps.

Jude provide Excellent answer. ContentProvider is used to provide the content to other apps and ContentResolver is used to resolve the uri of other apps that provide the content.
