Known Direct Subclasses ActivityResultContracts.CreateDocument, ActivityResultContracts.GetContent, ActivityResultContracts.GetMultipleContents, ActivityResultContracts.OpenDocument, ActivityResultContracts.OpenDocumentTree, ActivityResultContracts.OpenMultipleDocuments, ActivityResultContracts.PickContact, ActivityResultContracts.RequestMultiplePermissions, ActivityResultContracts.RequestPermission, ActivityResultContracts.StartActivityForResult, ActivityResultContracts.StartIntentSenderForResult, ActivityResultContracts.TakePicture, and 2 others. ActivityResultContracts.CreateDocument An ActivityResultContract to prompt the user to select a path for creating a new document, returning the content: Uri of the item that was created. ActivityResultContracts.GetContent An ActivityResultContract to prompt the user to pick a piece of content, receiving a content:// Uri for that content that allows you to use android.content.ContentResolver#openInputStream(Uri) to access the raw data. ActivityResultContracts.GetMultipleContents An ActivityResultContract to prompt the user to pick one or more a pieces of content, receiving a content:// Uri for each piece of content that allows you to use android.content.ContentResolver#openInputStream(Uri) to access the raw data. ActivityResultContracts.OpenDocument An ActivityResultContract to prompt the user to open a document, receiving its contents as a file:/http:/content: Uri. ActivityResultContracts.OpenDocumentTree An ActivityResultContract to prompt the user to select a directory, returning the user selection as a Uri. ActivityResultContracts.OpenMultipleDocuments An ActivityResultContract to prompt the user to open (possibly multiple) documents, receiving their contents as file:/http:/content: Uris. ActivityResultContracts.PickContact An ActivityResultContract to request the user to pick a contact from the contacts app. ActivityResultContracts.RequestMultiplePermissions An ActivityResultContract to request permissions ActivityResultContracts.RequestPermission An ActivityResultContract to request a permission ActivityResultContracts.StartActivityForResult An ActivityResultContract that doesn't do any type conversion, taking raw Intent as an input and ActivityResult as an output. ActivityResultContracts.StartIntentSenderForResult An ActivityResultContract that calls Activity#startIntentSender(IntentSender, Intent, int, int, int). ActivityResultContracts.TakePicture An ActivityResultContract to take a picture saving it into the provided content-Uri. ActivityResultContracts.TakePicturePreview An ActivityResultContract to take small a picture preview, returning it as a Bitmap. ActivityResultContracts.TakeVideo An ActivityResultContract to take a picture saving it into the provided content-Uri.

A contract specifying that an activity can be called with an input of type I and produce an output of type O Makes calling an activity for result type-safe.
