Can't Register More Than One Sensor In Android Service

I have a service which is called from an Activity. This Service Registers all Sensors and Registers Listener against them. EDIT: I have removed the two lines in onSensorChange() **

Solution 1:

Your OnSensorChanged event is setting the sensorManager to Null so as soon as a sensor is fired no more can be set.

EDIT

If you want each sensor to use a different listener, use something like this instead of implementing the methods on your activity:

privatevoidSetupSensors() {
    sensorManager.registerListener(MagneticListener, sensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD), SensorManager.SENSOR_DELAY_NORMAL);
}

privateSensorEventListenerMagneticListener=newSensorEventListener() {

    @OverridepublicvoidonSensorChanged(SensorEvent sensorEvent) {
        // Code here
    }

    @OverridepublicvoidonAccuracyChanged(Sensor sensor, int i) {

    }
};
