Hello :) I am working on an application that uses the compass and location to draw an arrow at the direction of a location. My problem is when I run my code on the emulator, all the arrows point the correct directions, and when I change the orientation of the emulator to landscape, all the arrows are still correct. But when I run the same application on my Nexus One, the arrows are all correct when the phone is vertical, but when it turns to landscape all of the arrow are off by 90 degrees. It keeps the "top" of the phone as the reference to North. Thus you must correct the compass for the orientation of the phone. Does this happen on all real phones and the emulator is the different one? Or is this just the Nexus One? Thanks :)
