I have a nice idea for android application want to make real scale, not like others which are fake i was thinking of how to do it but don't have any idea.
EDIT: want to make real scale (what means) It means for example i wanna calculate how much is the weight of a coin, then i'm putting the coin in the screen and calculates how much is the weight of the coin and if its possible the scale to get the weights to 50 grams
Hope its understood now.
Actually it is possible, just probably not precise enough. Most touch controllers can report touch pressure and it is available via MotionEvent.getPressure() call. So with some luck and tedious calibration you can measure weight of something. It is going to work better with cheaper resistive screen.
