1. 2014.8.9
the demo edition is over,and may have some bug ,so i will find time
to do somr test!
1. added an code that when the current point is too far from the
early point,then the current point is drop
1.bug fix: sometimes your total_dis data is lost.
 reason: the app's save code is write in the btn_stop's click listener
 so when you close the app without click the btn_stop,then you data
 is lost.
 ~solve: just put the save function code to the activity's onDestroy()
1. add the start_pos icon and stop_pos icon
2. the filter is comment,because someyimes it will freeze the app.
pos1 (0m)
"ok"->9
pos2 (9m)
-----------10m
"no"->11
pos3 (20m)
-----------10m
then the app draw process is stop
