# android.support.v4.content added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) # android.support.v4.content | This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings). ## Interfaces |----------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------| | [Loader.OnLoadCanceledListener](https://developer.android.com/reference/android/support/v4/content/Loader.OnLoadCanceledListener)\ | Interface that is implemented to discover when a Loader has been canceled before it finished loading its data. | | [Loader.OnLoadCompleteListener](https://developer.android.com/reference/android/support/v4/content/Loader.OnLoadCompleteListener)\ | Interface that is implemented to discover when a Loader has finished loading its data. | ## Classes |-------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [AsyncTaskLoader](https://developer.android.com/reference/android/support/v4/content/AsyncTaskLoader)\ | Static library support version of the framework's[AsyncTaskLoader](https://developer.android.com/reference/android/content/AsyncTaskLoader.html). | | [ContentResolverCompat](https://developer.android.com/reference/android/support/v4/content/ContentResolverCompat) | Helper for accessing features in[ContentResolver](https://developer.android.com/reference/android/content/ContentResolver.html)in a backwards compatible fashion. | | [ContextCompat](https://developer.android.com/reference/android/support/v4/content/ContextCompat) | Helper for accessing features in[Context](https://developer.android.com/reference/android/content/Context.html). | | [CursorLoader](https://developer.android.com/reference/android/support/v4/content/CursorLoader) | Static library support version of the framework's[CursorLoader](https://developer.android.com/reference/android/content/CursorLoader.html). | | [FileProvider](https://developer.android.com/reference/android/support/v4/content/FileProvider) | FileProvider is a special subclass of[ContentProvider](https://developer.android.com/reference/android/content/ContentProvider.html)that facilitates secure sharing of files associated with an app by creating a`content://`[Uri](https://developer.android.com/reference/android/net/Uri.html)for a file instead of a`file:///`[Uri](https://developer.android.com/reference/android/net/Uri.html). | | [IntentCompat](https://developer.android.com/reference/android/support/v4/content/IntentCompat) | Helper for accessing features in[Intent](https://developer.android.com/reference/android/content/Intent.html). | | [Loader](https://developer.android.com/reference/android/support/v4/content/Loader)\ | Static library support version of the framework's[Loader](https://developer.android.com/reference/android/content/Loader.html). | | [Loader.ForceLoadContentObserver](https://developer.android.com/reference/android/support/v4/content/Loader.ForceLoadContentObserver) | An implementation of a ContentObserver that takes care of connecting it to the Loader to have the loader re-load its data when the observer is told it has changed. | | [LocalBroadcastManager](https://developer.android.com/reference/android/support/v4/content/LocalBroadcastManager) | Helper to register for and send broadcasts of Intents to local objects within your process. | | [MimeTypeFilter](https://developer.android.com/reference/android/support/v4/content/MimeTypeFilter) | Provides utility methods for matching MIME type filters used in ContentProvider. | | [PermissionChecker](https://developer.android.com/reference/android/support/v4/content/PermissionChecker) | This class provides permission check APIs that verify both the permission and the associated app op for this permission if such is defined. | | [SharedPreferencesCompat](https://developer.android.com/reference/android/support/v4/content/SharedPreferencesCompat) | *This class was deprecated in API level 27.1.0. This compatibility class is no longer required. Use[SharedPreferences](https://developer.android.com/reference/android/content/SharedPreferences.html)directly.* | | [SharedPreferencesCompat.EditorCompat](https://developer.android.com/reference/android/support/v4/content/SharedPreferencesCompat.EditorCompat) | *This class was deprecated in API level 27.1.0. This compatibility class is no longer required. Use[SharedPreferences.Editor](https://developer.android.com/reference/android/content/SharedPreferences.Editor.html)directly.* | | [WakefulBroadcastReceiver](https://developer.android.com/reference/android/support/v4/content/WakefulBroadcastReceiver) | *This class was deprecated in API level 26.1.0. As of[Android O](https://developer.android.com/reference/android/os/Build.VERSION_CODES.html#O), background check restrictions make this class no longer generally useful. (It is generally not safe to start a service from the receipt of a broadcast, because you don't have any guarantees that your app is in the foreground at this point and thus allowed to do so.) Instead, developers should use android.app.job.JobScheduler to schedule a job, and this does not require that the app hold a wake lock while doing so (the system will take care of holding a wake lock for the job).* | - ## Interfaces - [Loader.OnLoadCanceledListener](https://developer.android.com/reference/android/support/v4/content/Loader.OnLoadCanceledListener) - [Loader.OnLoadCompleteListener](https://developer.android.com/reference/android/support/v4/content/Loader.OnLoadCompleteListener) - ## Classes - [AsyncTaskLoader](https://developer.android.com/reference/android/support/v4/content/AsyncTaskLoader) - [ContentResolverCompat](https://developer.android.com/reference/android/support/v4/content/ContentResolverCompat) - [ContextCompat](https://developer.android.com/reference/android/support/v4/content/ContextCompat) - [CursorLoader](https://developer.android.com/reference/android/support/v4/content/CursorLoader) - [FileProvider](https://developer.android.com/reference/android/support/v4/content/FileProvider) - [IntentCompat](https://developer.android.com/reference/android/support/v4/content/IntentCompat) - [Loader](https://developer.android.com/reference/android/support/v4/content/Loader) - [Loader.ForceLoadContentObserver](https://developer.android.com/reference/android/support/v4/content/Loader.ForceLoadContentObserver) - [LocalBroadcastManager](https://developer.android.com/reference/android/support/v4/content/LocalBroadcastManager) - [MimeTypeFilter](https://developer.android.com/reference/android/support/v4/content/MimeTypeFilter) - [PermissionChecker](https://developer.android.com/reference/android/support/v4/content/PermissionChecker) - [SharedPreferencesCompat](https://developer.android.com/reference/android/support/v4/content/SharedPreferencesCompat) - [SharedPreferencesCompat.EditorCompat](https://developer.android.com/reference/android/support/v4/content/SharedPreferencesCompat.EditorCompat) - [WakefulBroadcastReceiver](https://developer.android.com/reference/android/support/v4/content/WakefulBroadcastReceiver)
