I’m continuing Rxfication of the Android. Recently I released brand new library called ReactiveAirplaneMode. As you may guess, it allows listening Airplane mode on Android device with RxJava observables. A usual I’ve hidden all implementation details, BroadcastReceivers and rest of the Android related stuff behind RxJava abstraction layer, so API is really simple. Just take a look on that:

1
2
3
4
5
ReactiveAirplaneMode.create()
    .observe(context)
    .subscribeOn(Schedulers.io())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(isOn -> textView.setText(String.format("Airplane mode on: %s", isOn.toString())));

In the code above subscriber will be notified only when airplane mode changes. If you want to read airplane mode and then listen to it, you can use the following method:

1
2
3
4
5
ReactiveAirplaneMode.create()
    .getAndObserve(context)
    .subscribeOn(Schedulers.io())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(isOn -> textView.setText(String.format("Airplane mode on: %s", isOn.toString())));

If you want to check airplane mode only once,
you can use get(context) method, which returns Single<Boolean> value:

1
2
3
4
5
ReactiveAirplaneMode.create()
    .get(context)
    .subscribeOn(Schedulers.io())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(isOn -> textView.setText(String.format("Airplane mode on: %s", isOn.toString())));

If you want to check airplane mode only once without using Reactive Streams, just call isAirplaneModeOn(context) method:

1
boolean isOn = ReactiveAirplaneMode.create().isAirplaneModeOn(context);

You can add this library to your project via Gradle:

dependencies {
  compile 'com.github.pwittchen:reactiveairplanemode:0.0.1'
}
