Android RxJava wrapper for startActivityForResult

## RxIntent 

#### Setup

Add to root build.gradle

```groovy

    allprojects {

        repositories {

            jcenter()

            mavenCentral()

        }

    }

```

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

```groovy

    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

```java

    Observable 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.

```java

    final Observable rxIntentObservable = RxIntent.observeActivityForResult(RxIntentActivity.this, REQUEST_CODE);

    

    final Observable result = RxView.clicks(view)

            .flatMap(new Func1>() {

                @Override

                public Observable call(Void aVoid) {

                    return RxIntent.startAndObserveActivityForResult(RxIntentActivity.this, intent, REQUEST_CODE);

                }

            });

    final Observable rxIntentResultObservable = Observable.merge(rxIntentObservable, result);

    //handle the events from the rxIntentResultObservable

```
