hi I am a newbie. currently I am trying to make a program using android sensors .
I hope to get accelerations of 3 axis in earth coordinate system. It is easy to get 3 accelerations and orientation angles in phone coordinate system. So I made 3d transformation using equations as http://planning.cs.uiuc.edu/node102.html However it seems that it's not accurate and android provides easier and more accurate way. from android dev doc "It is preferable to use getRotationMatrix() in conjunction with remapCoordinateSystem() and getOrientation() to compute these values; while it may be more expensive, it is usually more accurate. " But I don't know how to using them. Can any one give me some more detailed guidance or sample code using these methods?
