Android Task Automation

Hello; In simple words what I am looking for is "android task automation script or app" The task I need automated is very simple and straightforward... I want a program script that search and scans for specific NUMBER I tell it to find in the background wait till it appears on the android screen (e.g... $1.05) and then click on it literally in nanoseconds as soon as it appears on the device screen .. Basically I want to win auction bids on this android app that I am using to buy things. (JUST FIND THE NUMBERS I WANT AND CLICK ON IT THEN CLICK "YES" THAT IS IT) Task/> 1/ Find Number (input box) 2/ Click Number (Very fast) 3/ Click yes as soon as it appears on screen (Very fast)... DONE >/ FYI.. I can send you screen shot of what the bidding app looks like and what the numbers look like when they appear on my screen. Any question??? Is this something you can do?
