Personalisation
Apps may be personalised by developers. This is an initial approach to identifying such changes in the UI using static methods.
Extracting Colour changes
Apps can use different colours in different territories.
One way of finding changes is to extract the colours from the XML files and compare them.
colours_xml_file = apk_name
personal = Personalisation()
all_colours = personal.get_colours(apk_name)
This will return a list of app against the colours and values.
