RxSensor

A lightweight wrapper around SensorManager which introduces reactive stream semantics to Sensor and Trigger data.

Usage

To use RxSensor, an RxSensorManger object must be constructed from a standard SensorManager.

SensorManager sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);

RxSensorManager rxSensorManager = new RxSensorManager(sensorManager);

observeSensor()

This reactive implementation of a SensorManager exposes methods to listen to a specific Sensor as an Observable<SensorEvent> stream. These methods correspond roughly to SensorManager's various supported [registerListener](http://developer.android.com/reference/android/hardware/SensorManager.html#registerListener(android.hardware.SensorEventListener, android.hardware.Sensor, int, int)) methods.

Observable<SensorEvent> sensorObservable =
        rxSensorManager.observeSensor(Sensor.TYPE_ACCELEROMETER, SensorManager.SENSOR_DELAY_NORMAL);
sensorObservable.subscribe(new Action1<SensorEvent>() {
    @Override public void call(SensorEvent event) {
        // TODO react to event...
    }
});

observeTrigger()

In addition to observing SensorEvent streams, RxSensorManager also provides the functionality to observe a TriggerEvent. This method roughly corresponds to SensorManager's [requestTriggerSensor](http://developer.android.com/reference/android/hardware/SensorManager.html#requestTriggerSensor(android.hardware.TriggerEventListener, android.hardware.Sensor)) method.

NOTE: While this library targets API 9 and above, TriggerEvents are only supported on API 18 and above. This means that observeSensor also targets API 18 and will throw an exception if used on a low API level.

Observable<TriggerEvent> triggerObservable =
        rxSensorManager.observeTrigger(Sensor.TYPE_SIGNIFICANT_MOTION);
triggerObservable.subscribe(new Action1<TriggerEvent>() {
    @Override public void call(TriggerEvent event) {
        // TODO react to event...
    }
});
