title: Android get accelerometers on earth coordinate system
body: <p>I'd like to get accelerometers on Android and have them on the earth coordinate system, just like on this topic <a href="https://stackoverflow.com/questions/11578636/acceleration-from-devices-coordinate-system-into-absolute-coordinate-system">Acceleration from device&#39;s coordinate system into absolute coordinate system</a> or here <a href="https://stackoverflow.com/questions/5464847/transforming-accelerometers-data-from-devices-coordinates-to-real-world-coordi">Transforming accelerometer&#39;s data from device&#39;s coordinates to real world coordinates</a> but these solutions don't work for me. I'm working on Processing. The project is simply to track the phones accelerations in space, no matter how it is (standing, on the side...). I'm new to Android too.
  I'd appreciate your help!
  Thank you. </p>
  
  <p>Edit : I don't need the phones exact position, only accelerations.</p>
