Android content provider-create a content provider (intent object and data access)

ApplicationProgramYou can use an intent object to indirectly access a content provider. The application does not call any contentresolver or contentprovicer method. On the contrary, it sends an intent object to the activity that starts it. This intent object is usually part of its own application. The target activity obtains and displays data in its UI. Depending on the action in intent, the target activity can also prompt the user to modify the data of the provisioner. The intent object can also contain the additional data displayed by the target activity in the UI. Then, before you use it to modify the data in the provisioner, you have the option to change the data.

You may want to use the access to the intent object to ensure data integrity. Your providers may rely on strictly defined business logic to insert, update, and delete data. If so, allowing other applications to directly modify data may result in invalid data. If you want developers to use intent objects for access, you must have detailed documents to explain to them why intent objects are used for access in their own application UI.CodeTo modify data.

Processing an input intent object for which you want to modify the data of the provider is different from processing other intent objects, in the "Intents And intent filters" topic, you can learn more about using intent objects.
