AndroidSensors_Example

AndroidSensors is a simple library, that acts as a wrapper around the Android Sensor's system, converting the stream of sensor data, into a Flowable that emits the same events, so that you can combine more sources of data for more complex operations, RxJava2 compatible, Dagger 2.

Example Sensor data

• If we want to obtain shake value from ax gravity we can use the method getShakeSensors

Disposable mShakeDisposable = mSensorHelper.getShakeSensors(Sensor.TYPE_ACCELEROMETER, shakeObserverResult);

` /** * Method used to return shake value from ax gravity * * @param sensorType * @param resultObserver * @return */

public Disposable getShakeSensors(int sensorType, CoreObserverResult<Boolean> resultObserver) {
    return mCoreSensors.observeSensor(sensorType)
            .subscribeOn(mSchedulersFacade.computation())
            .observeOn(mSchedulersFacade.ui())
            .filter(CoreSensorFilter.filterSensorChanged())
            .map(coreSensorEvent -> {
                SensorEvent event = coreSensorEvent.getSensorEvent();
                float ax = event.values[0];
                float ay = event.values[1];
                float az = event.values[2];
                double magnitudeSquared = ax * ax;
                float linear = az * az + ay * ay;
                if (magnitudeSquared >= linear) {
                    return magnitudeSquared > DEFAULT_ACCELERATION_SHAKE ? true : false;
                }
                return false;
            })
            .subscribe(coreSensorEvent -> resultObserver.onNext(coreSensorEvent), throwable -> {
                if (throwable instanceof SensorNotFoundException) {
                    SensorNotFoundException sensorNotFoundException = (SensorNotFoundException) throwable;
                    resultObserver.onError(sensorNotFoundException);
                }
            });
}
