simulation - How to simulate HAND GESTURES using code in Android -

i developing user guide tutorial app (a softkeyboard) , in tutorial need programmatically simulate set of several hand gestures including "click", "swipe", "long press , swipe" etc. have no basic idea how achieve , have searched through internet still did not useful findings.

so there 1 kindly give me advice on how achieve this, if possible, please give me simple code example on this. much, please help.

you don't need simulate hand gestures tutorial. pretend hand gestures executed. instance, want teach user long press on button trigger action. in case, display graphic or animation directs users button , indicates long press. could, instance, show image of finger presses on button. then, trigger action directly. don't need simulate gesture, go ahead , trigger action directly.
