| Content providers manage access to a structured set of data. They encapsulate the |
| data, and provide mechanisms for defining data security. Content providers are the standard |
| interface that connects data in one process with code running in another process. |
| </p> |
| <p> |
| When you want to access data in a content provider, you use the |
| {@link android.content.ContentResolver} object in your |
| application's {@link android.content.Context} to communicate with the provider as a client. |
| The {@link android.content.ContentResolver} object communicates with the provider object, an |
| instance of a class that implements {@link android.content.ContentProvider}. The provider |
| object receives data requests from clients, performs the requested action, and |
| returns the results. |
| </p> |
| <p> |
| You don't need to develop your own provider if you don't intend to share your data with |
| other applications. However, you do need your own provider to provide custom search |
| suggestions in your own application. You also need your own provider if you want to copy and |
| paste complex data or files from your application to other applications. |

| Android itself includes content providers that manage data such as audio, video, images, and |
| personal contact information. You can see some of them listed in the reference |
| documentation for the |
| <code><a href="{@docRoot}reference/android/provider/package-summary.html">android.provider</a> |
| </code> package. With some restrictions, these providers are accessible to any Android |
| application. |
