Hello
I try to use Appium for testing android mobile app created using Unity3d.
I have coordinates of my element (using openCV)
My environment:
v1.1.0-beta.2
android emulator (4.4 or 5.1)
python 2.7.13
appium-python-client (installed ‘pip install appium-python-client’)
I run this code:
…
a1 = TouchAction(self.driver)
a1.tap(element, coordinates[‘x’], coordinates[‘y’], 2).perform()
and I see that pressing in center of element always
Help me pls 
Why I can’t click using coordinates of element?
Below log from appium :
