ContentProviderClient

Kotlin |Java

open class ContentProviderClient : AutoCloseable

kotlin.Any
↳	android.content.ContentProviderClient

The public interface object used to interact with a specific ContentProvider.

Instances can be obtained by calling android.content.ContentResolver#acquireContentProviderClient or android.content.ContentResolver#acquireUnstableContentProviderClient. Instances must be released using close() in order to indicate to the system that the underlying ContentProvider is no longer needed and can be killed to free up resources.

Note that you should generally create a new ContentProviderClient instance for each thread that will be performing operations. Unlike ContentResolver, the methods here such as #query and #openFile are not thread safe -- you must not call close() on the ContentProviderClient those calls are made from until you are finished with the data they have returned.
