Answer 1

When measuring movement there is generally no concept of orientation. A multi-axis accelerometer measuring static acceleration (acceleration due to gravity) could be used to calculate the angle relative the earth.

Most androids phones comes with a number of sensors such as gyroscope etc which can interfaced. See the javadocs for SensorManager and the various types of SensorEvents.
