Futurice RxJava exercise

Your job is to implement the exercises grouped in each packages

You can run all the unit test and see it fail:

./gradlew test

or do it per exercise and run test by packages:

./gradlew test --tests com.futurice.rxandroidtest.craneexercise.*

Crane exercise

1. Make an RxJava chain that uses Crane.fromPaper to process the paperStack and at the end call subscriber with the finished list. Give the Crane.fromPaper function the same scheduler that the function receives. You do not need to worry about in which order the cranes are.

2. Because some colors more difficult to fold than others, the execution time of Crane.fromCrane varies. Make sure your solution retains the order. If the papers are in list ["yellow", "orange", "red"] the resulting list of cranes should be so that i. e. first crane is if color "yellow".

3. We need to fold faster! Make all makeCrane operations run simultanously while still retaining the order in which the papers are given.

4. Make the chain work with a source of type Observable<List<Paper>> that does not complete. The time limit is the same as for function 3.

article Exercise

1. Create an observable which combine two source of ids, for each id, fetch the actual article.

multicasting exercise

1. find the right combination of pulish/autoconnect/connect/refcount/replay for each exercise
