How to Accessing the Tesseract Cloud-Service from Android

As the question title suggests, I am trying to implement Tesseract Cloud-Service into my app. This is the tutorial I am currently using. For the type of app I am making, the best way to implement this into my app is through the Cloud Service. I am VERY new to the world of OCR, in any form. Can anybody provide like an example of this being implemented? I am having error after error with this after downloading and importing the http clients library. (And yes, I am 100% positive I have imported them correctly). Any and all help is appreciated. Thanks everyone!
