Note: I'll use the terms "back end" and "front end" as practical concepts, as I don't profess know the subtleties of the definitions. I'm an advanced hobbyist programmer, not a professional. I'm using Eclipse Juno for development. Minimum Target is Android 2.3.3
I built a android app which I collect data on. I've deployed the android app to my phone and it's worked fine for a few years. I generated an app-engine back end so I could store the data externally, as well as request the data from the datastore from time to time. All that works fine in the local development app engine environment. I built a Google web app separately with which I access the web, google tools, etc and generate data which I store in datastore. Couple servlets, couple jsp pages. This application works fine. It is deployed to Google App Engine. Next I wanted to get the data that the web app generated to my phone. After researching, experimenting with, and glazing over with Maven, modules, and more documentation overload to wade through and not understand, I found that if I just copied the endpoints from my originally generated app-engine back end to the Google web application, I could communicate with the web app from the android app in the local development server environment - running the android app on the emulator. I then deployed the web application updated with the cloud endpoints to Google App Engine. The "front end" works as before. I've tried to communicate with the deployed Web app from the android app running in the emulator and get the below error stream in the log. It looks to me like the android app tries to connect and the app engine refuses the connection. I realize there's not much concrete stuff to look at here, what should I post? Thanks for your time and interest.
