Hi, the description of getRotationMatrix() on the Android web says "The matrices returned by this function are meaningful only when the device is not free-falling and it is not close to the magnetic north. If the device is accelerating, or placed into a strong magnetic field, the returned matrices may be inaccurate."
I wanted to get the rotation matrix first and then the orientation by using getOrientation(). But what i'm dealing with is the phone accelerating case (i.e. the phone is moving constantly), so how am I supposed to get the phone's orientation data during the moving process??? Thank you! PS. I wonder how the airplane actually determines its orientation when it's flying??? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
