Get absolute path from home page

I am newbie to appium.
to get idea of problem I will explain you my scenario.
I gave settings package in apppackage and appactivity.This opens appium settings. Here I will use find_element_by_id and pass the values I got from android uiautomator. Then I will store this webelement object in a variable. Then I click on back button and it goes to home page. Now by using previously stored webelement object I use click method on it. and it gives me error.

So my question is there is any way I can click on given webelement when I am on different screen.
I am using appium 1.12.1 and python client version 0.4 and google nexus 5 device with android version 6.0.1 and uiautomator 2
