What is Android Content Providers for? Explain its Additional Components.

 

Android Content Providers

 

In android, Content Providers are used to exchange the data between the apps based on the requests. The Content Providers can share the app data that store in the file system, SQLite database, on the web or any other storage location that our app can access.

 

By using Content Providers, other apps can query or modify the data of our app based on the permissions provided by content provider. For example, android provides a Content Provider (ContactsContract.Data) to manage contacts information, by using proper permissions any app can query the content provider to perform read and write operations on contacts information.
