ResultReceiver
open class ResultReceiver : Parcelable
Generic interface for receiving a callback result from someone. Use this by creating a subclass and implement onReceiveResult, which you can then pass to others and send through IPC, and receive results they supply with send.
Note: the implementation underneath is just a simple wrapper around a Binder that is used to perform the communication. This means semantically you should treat it as such: this class does not impact process lifecycle management (you must be using some higher-level component to tell the system that your process needs to continue running), the connection will break if your process goes away for any reason, etc.
Summary

From class Parcelable
Int |
CONTENTS_FILE_DESCRIPTOR
Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.
|
Int |
PARCELABLE_WRITE_RETURN_VALUE
Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Public constructors
ResultReceiver
ResultReceiver(handler: Handler!)
Create a new ResultReceive to receive results. Your onReceiveResult method will be called from the thread running handler if given, or from an arbitrary thread if null.
Public methods
describeContents
open fun describeContents(): Int
send
open fun send(
resultCode: Int,
resultData: Bundle!
): Unit
Deliver a result to this receiver. Will call onReceiveResult, always asynchronously if the receiver has supplied a Handler in which to dispatch the result.
| Parameters |
resultCode |
Int: Arbitrary result code to deliver, as defined by you. |
resultData |
Bundle!: Any additional data provided by you. |
writeToParcel
open fun writeToParcel(
out: Parcel,
flags: Int
): Unit
Protected methods
onReceiveResult
protected open fun onReceiveResult(
resultCode: Int,
resultData: Bundle!
): Unit
Override to receive results delivered to this object.
| Parameters |
resultCode |
Int: Arbitrary result code delivered by the sender, as defined by the sender. |
resultData |
Bundle!: Any additional data provided by the sender. |
