Appium(Android Mobile) : Click button using X Y coordinate(if can't find ID or Xpath)?
I would probably find a element you can find and use an offset from that location. See this to get a Point from element: http://appium.io/docs/en/commands/element/attributes/location/
To click on some coordinates:
TouchAction touchAction=new TouchAction(driver); touchAction.tap(xPoint, yPoint).perform();
