Android RxJava wrapper for startActivityForResult

RxIntent

Setup

Add to root build.gradle

    allprojects {
        repositories {
            jcenter()
            mavenCentral()
        }
    }

In your module build.gradle file add to the dependencies block

    dependencies {
        compile "com.twistedequations.rx:rx-intent:1.0.0"
    }

If its giving an error about not finding a jar file use com.twistedequations.rx:rx-intent:1.0.0@aar instead

Usage

To listen for onActivityForResultEvents

    Observable<RxIntentResult> observable = RxIntent.observeActivityForResult(activity, requestCode);

The Observable will emit one event when the result activity returns and then will finish with an onCompleteEvent.

To start the activity for result use the RxIntent.startActivityForResult(activity, intent, options, requestCode) method. this will start the activity and any RxIntent.observeActivityForResult(activity, requestCode) observables will emit the result of the callback as log as the request codes are the same.

Use RxIntent.startAndObserveActivityForResult(activity, intent, options, requestCode) method to start the activity

To Handle activities being recreated while in the next activity is visible you can merge the results of observeActivityForResult() with a startAndObserveActivityForResult() call into a single stream.

    final Observable<RxIntentResult> rxIntentObservable = RxIntent.observeActivityForResult(RxIntentActivity.this, REQUEST_CODE);
    
    final Observable<RxIntentResult> result = RxView.clicks(view)
            .flatMap(new Func1<Void, Observable<RxIntentResult>>() {
                @Override
                public Observable<RxIntentResult> call(Void aVoid) {
                    return RxIntent.startAndObserveActivityForResult(RxIntentActivity.this, intent, REQUEST_CODE);
                }
            });

    final Observable<RxIntentResult> rxIntentResultObservable = Observable.merge(rxIntentObservable, result);
    //handle the events from the rxIntentResultObservable
