With this simple library use your OnActivityResult results in any class (not just in Activity or Fragment) and use it in a reactive way within your observable chains.

The library attaches one Fragment to the Activity, sends desired intents and listens to OnActivityResult. You can read more about it in this Medium article.

The source code is easy to read and understand. Library code is written in Java to avoid unnecessary dependencies, and Sample code is written in Kotlin to avoid unnecessary boilerplate. :)

Simply instantiate it with an Activity object and use it anywhere, or if you are using Dagger, create it in your Activity scope and provide to all other classes that need to use it.

  RxActivityResult(this) // this -> Activity

To start an activity for result, call the start method and send in the intent you wish to start. The method returns a Single which returns the ActivityResult object.

  rxActivityResult.start(intent) // intent -> bluetooth, gallery, other activity...
        .subscribe({ Log.d("Result", it) }, { it.printStackTrace() })       

The ActivityResult class consists of:

  // Fields
  val resultCode: Int
  val data: Intent?

  // Convenience methods
  fun isOk(): Boolean
  fun isCanceled(): Boolean
  fun isFirstUser(): Boolean

The library also supports sending PendingIntents for Resolutions. See Location button in Sample.
