of Android Activity.
2.Almost for all applications it is important to know how does the screen work,
i.e the X and Y coordinator.
3.Some developers will require the multi touch support of a phone to develop
the apps.

accelerometer many innovative apps/games can be developed,so
this app just shows how it works with respect to ground.
