android SensorEventListener problem

Question

I am trying to create an application which reads data from digital compass. I tried to reuse the code from the book Professional Android Application Development but the IDE

Answer 1

The method is just deprecated, you have to use

registerListener(SensorEventListener, Sensor, int) 

instead.

Answer 2

There is a separate SensorEventListener class you need to use. See here.

Answer 3

You actually need to pass in a Senor object, not just the ID of it.

Sensor sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION); sensorManager.registerListener(sensorListener, sensor, SensorManager.SENSOR_DELAY_FASTEST)

Answer 4

I had the same problem but when I casted the first 2 parameters as (SensorEventListener) and (Sensor) it worked. I then realised the problem was that for some reason I had declared the Sensor as type "Object" and not "Sensor", so Eclipse failed to identify the types of parameters.

This worked for me:

mSensorManager.registerListener((SensorManager)this, (Sensor)mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);

But now I have correctly declared mAccelerometer as type Sensor I no longer need the casts.
