Known Direct Subclasses

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:` `Uri`s.
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 video` 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.

Summary

	`SynchronousResult` The wrapper for a result provided in `getSynchronousResult`

Public constructors
`<init>()` 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.

Public methods
abstract Intent	`createIntent(@NonNull context: Context, input: I)` Create an intent that can be used for Activity#startActivityForResult
open ActivityResultContract.SynchronousResult<O>?	`getSynchronousResult(@NonNull context: Context, input: I)` An optional method you can implement that can be used to potentially provide a result in lieu of starting an activity.

createIntent

@NonNull abstract fun createIntent(
    @NonNull context: Context, 
    input: I
): Intent

Create an intent that can be used for Activity#startActivityForResult

getSynchronousResult

@Nullable open fun getSynchronousResult(
    @NonNull context: Context,

An optional method you can implement that can be used to potentially provide a result in lieu of starting an activity.

Return
`ActivityResultContract.SynchronousResult<O>?`	the result wrapped in a `SynchronousResult` or `null` if the call should proceed to start an activity.
