Can anyone please let me know, does Google app engine channel api be integrated within django-nonrel ? My whole application is in django-nonrel running on GAE but now I need to use the channel api for server push purpose.
I think channel api uses GAE webapp. Will it work with django-nonrel ?
Thanks,
Sunil
No-matter which framework you are using, you can always use the provided appengine api's as they are documented. There is no "django specific abstraction" for the channel api last I checked, but it will work happily alongside anything else you create.

I have been developing an online accounting software which is a web application. We use Secured Google Cloud Endpoints in our project. Now I would like to securely access those endpoints in phonegap. So, for that I would like to do OAuth2.0(google) and access my API securely. I have been struggling for a while to find good JavaScript Client Libraries to access my Secured API in phoneGap.
Please help me...
Any replies would be appreciated.
Finally After some struggle I have figured out the solution. If we are trying to do Google OAuth in phone gap its better to use normal JQuery and for calling the Secured Google Cloud Endpoints we can go with Google JavaScript Client Libraries. I have found a sample project oauth-google-api-gapi-phonegap-childbrowser-jquery which is a very good start for the beginners.
I am trying Python quickstart project (https://developers.google.com/glass/develop/mirror/quickstart/python) and it is implemented on GAE, however, looking at the code it does not seem that there is much dependency on App Engine itself (code is kind of complicated and I still do not understand it all though).
Is this required to host Mirror-based glassware on App Engine?

No, it is not required. What you really need is ability to use Google API's and Mirror API is just one of them.
Java quick start, for example does not run on top of GAE.
I have an AppEngine application which uses Google Accounts as authentication. What is the approach or idea on seeing if someone is online or using the application? And able to chat to online users.
Thanks.
The official way to implement chat on App Engine is using the Channel API. However, the quotas are strange, and it's fairly expensive at $0.01/100 connections.
I would recommend using a hosted web socket service like Pusher, or running your own nodejs server on another host.
You can use the XMPP API to get users status, and send them messages that appear in Google Chat.

I'm using GWT to create a simply app that allows teachers to create easily their own lessons.
The App is going to be on Google App Engine but I want to store lessons in user's Google Docs space .
Is it possible?
As far as I know gwt transforms java into javascript but google docs api is java, do i have to upload the java library to de app engine storage?
any place to start? any advice?
Thanks...
You need server side proxy for GWT client.
Your GWT client communicates with the servlet. The servlet is the actual agent using the google docs API.
Please read my explanation at http://h2g2java.blessedgeek.com/2010/05/accessing-google-userservice-from-gwt.html.
It explains how to get a GWT client could communicate with a Java based Google API. It explains that since GWT requires all Java source involved to be available to the GWT compiler, there are cases that you simply cannot get GWT client to do the task directly.
http://h2g2java.blessedgeek.com/2009/08/tablemgr-gae-gwt-gdata-with-rpc.html similarly explains how to combine gae + gwt + google docs, using the proxy approach. The posting is quite old and therefore the web site it points to does not work anymore because I have not updated the gae app with google mandated authentication measures. But it should work on your local machine.
The above subscribes to a webserver flow paradigm.
However, Google APIs are essentially REST APIs, which allows you to access them directly using your javascript or GWT client. So, instead of using the Java docs for Google APIs, you need to read the Google REST API docs.
http://code.google.com/more/, among other whatnots, provides a list of all the Google cloud APIs. To avoid using the webserver-proxy flow paradigm, choose the javascript or REST version of the API docs.
Here is the google docs/data API:
http://code.google.com/apis/gdata/docs/client-libraries.html.
Choose the javascript API:
http://code.google.com/p/gdata-javascript-client/
I advise you to first practice using these APIs by coding in javascript. Then you would get a good grasp of what you need to do in GWT.
You should use the GWT API for authentication prior to accessing the Google REST APIs.
http://code.google.com/p/gwt-oauth2/.
Essentially, you are obtaining an authenticated token which your client could use to access Google's data thro their REST APIs.
FYI, REST APIs are, in plain speak, URLs in a defined specification, where data transmission is by convention mostly in JSON or XML.
What is the easiest way to use the Amazon Product API on the Google App Engine? How do you work around the socket limitations of Google App Engine?
Are you using the REST API ? If it's purely a REST API, you should be able to make calls using the urlfetch service.
What have you tried so far, and what errors has it given you?
Also, are you using the Java or Python version of App Engine?
I'm using this library together with Beautiful Soup on App Engine. Had no problems so far.
This basic Amazon Product API module is compatible with Google App Engine.
