Android reactive programming with Rxjava
summary
Hands-on RxJava on Android: builds an Observable from installed apps, shows emitting with subscriber.onNext, filters with distinct/sample/take/flatMap/map, and transforms app info into names or bitmaps. Demonstrates thread handling with subscribeOn(Schedulers.io()) observeOn(AndroidSchedulers.mainThread()) to avoid UI-thread crashes. Integrates Retrofit (Rx-compatible), RxAndroid, Dagger 2, ButterKnife and an image loader to fetch StackOverflow users and OpenWeatherMap icons; demo app runs and scales (author cites a related app with 100,000 downloads).
