How to merge two microsoft sample apps

[zallia2]

How can I join https://github.com/Microsoft/Cognitive-Vision-Android with https://github.com/Microsoft/Cognitive-Face-Android so that both apps are combined into one. As I was looking to make an app which combined both technologies to help blind people familiarise themselves with certain things by letting them know what it is. Can you please send me the file/folder with the solution by providing a link to it and how and where I can use it as I'm pretty new to android app development. When someone provides the code I need to know where to add it and test it that it works. So basically I am trying to create a similar app to Seeing AI. All help is well appreciated. Thanks
