I have a problem with the sensor manager and errors in the logcat. When I register the listener with this line :
sensorMgr.registerListener(this, sensorMgr.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
I recieve theses lines in the logcat with three errors.

It works great, there is no problem but how can I avoid these errors ?
PS : I don't use the deprecated version.
It's not an error, this is a normal behavior, they marked it as error by mistake. You can run it on an ICS device and see the same log line in a "debug" log-type.
