I wanted to ask what the difference between Google App Engine, Google APIs Console and Google Cloud Console is?
I will deploy a Project which will fetch some Websites and provide the data to my Android Application.
What is the best to use? I do not know what is for what.
Google App Engine lets you run web applications on Google's infrastructure : https://developers.google.com/appengine/docs/whatisgoogleappengine
Google APIs Console is Console to administrate Google API (deprecated)
Google Cloud Console is new version of Google APIs Console.
So for your Project use Google App Engine. And for example use URL Fetch https://developers.google.com/appengine/docs/python/urlfetch/
