Intercepting screen taps and emulating taps at a specific location

You need to write an application for Android, which will intercept the pressing at any place on the screen of the device (being rolled up, or with sizes reduced to one pixel) and then emulate the pressing at a certain predetermined place on the screen of the device.
Roughly speaking: the application waits for tap on the screen and, upon detection of such, reacts by emulating a press at a predetermined place on the screen.
