[android-developers] Re: Warning users of strong magnetic field

How about using the field strength values: determine a reasonable range and put up a Toast if the field strength is too large?

Does anybody know how to warn users of string magnetic field? I'm creating a compass application. But when there are magnetic items around, the north direction is going wrong.

Using SensorEventListener#onAccuracyChanged doesn't help.

Is there any tutorial telling me how to handle this problem?

FYI, I followed this tutorial to create this compass app: http://stackoverflow.com/questions/4819626/android-phone-orientation-overview-including-compass
