A class that can call startActivityForResult-style APIs without having to manage request codes, and converting request/response to an Intent

Summary

Public methods
abstract @NonNull ActivityResultLauncher<@NonNull I>	<I, O> registerForActivityResult(     @NonNull ActivityResultContract<@NonNull I, @NonNull O> contract,     @NonNull ActivityResultCallback<@NonNull O> callback ) Register a request to start an activity for result, designated by the given contract.
abstract @NonNull ActivityResultLauncher<@NonNull I>	<I, O> registerForActivityResult(     @NonNull ActivityResultContract<@NonNull I, @NonNull O> contract,     @NonNull ActivityResultRegistry registry,     @NonNull ActivityResultCallback<@NonNull O> callback ) Register a request to start an activity for result, designated by the given contract.

Extension functions

final @NonNull ActivityResultLauncher<Unit>	<I extends Object, O extends Object> ActivityResultCallerKt.registerForActivityResult(     @NonNull ActivityResultCaller receiver,     @NonNull ActivityResultContract<@NonNull I, @NonNull O> contract,     @NonNull I input,     @NonNull Function1<@NonNull O, Unit> callback ) A version of ActivityResultCaller.registerForActivityResult that additionally takes an input right away, producing a launcher that doesn't take any additional input when called.

Public methods

registerForActivityResult

@NonNull
public abstract ActivityResultLauncher<@NonNull I> <I, O> registerForActivityResult(
    @NonNull ActivityResultContract<@NonNull I, @NonNull O> contract,
    @NonNull ActivityResultCallback<@NonNull O> callback
)

Register a request to start an activity for result, designated by the given contract. This creates a record in the registry associated with this caller, managing request code, as well as conversions to/from Intent under the hood. This *must* be called unconditionally, as part of initialization path, typically as a field initializer of an Activity or Fragment.

Parameters
<I>	the type of the input(if any) required to call the activity
<O>	the type of output returned as an activity result
@NonNull ActivityResultContract<@NonNull I, @NonNull O> contract	the contract, specifying conversions to/from Intents
@NonNull ActivityResultCallback<@NonNull O> callback	the callback to be called on the main thread when activity result is available

Returns
ActivityResultLauncher<@NonNull I>	the launcher that can be used to start the activity or dispose of the prepared call.

@NonNull ActivityResultRegistry registry	the registry where to hold the record.
@NonNull ActivityResultCallback<@NonNull O> callback	the callback to be called on the main thread when activity result is available

Returns
ActivityResultLauncher<@NonNull I>	the launcher that can be used to start the activity or dispose of the prepared call.
