This sort of tells me that your x,y co-ordinate is fine for Android,
but the press&release events are not in-line with what Android
expects. It may be a good idea to check if your touch driver reports
BTN_TOUCH with a valid value for touch-down and BTN_TOUCH with 0 as
value for touch-up events. Also the ABS_PRESSURE value must be
reported properly in the driver.

I presume you have built the ts_calibrate dynamically (with the
library being shared object). Android linker will not be able to
launch the process as the symbol resolution fails. Hence the simple
trick would be to build the ts_calibrate statically.
