The diagram of the linear sensor coordinate system here <http://developer.android.com/reference/android/hardware/SensorEvent.html> seems to be wrong. I have a test program running on my HTC Desire (Android 2.2), showing me values from the accelerometer. As it lies horizontally, face-up on my desk, the Z value is positive (around 9.8, as you would expect). But that diagram says that positive Z is up, not down. I tilt the phone to the left, and the X value increases. Tilt to the right, it decreases. But the diagram says positive X is to the right, not the left. Tilt it up, the Y value increases. Hold it vertical, with the display upside down, and the Y value shows negative. Again, completely the opposite to the diagram.
