gapi fails to load when use locally (not on a webserver)

Load the code in the linked fiddle as a local webpage (ie file:///home/test.html).
Fiddle: http://jsfiddle.net/glitchtechscience/LsAwT/2/ What is the expected output? What do you see instead? I should see two alerts. I do see two on a web server, but when run locally (html5 app), it fails with the message "Unable to post message to file://. Recipient has origin null.". What version of the product are you using? On what operating system? Latest. Chromium 18 on Ubuntu 12.04.

Try running it using a local-server(XAMPP maybe) so the header will look similar to "http://localhost/yourpath/test.html

Forgot to mention, also specify "http://localhost/ at the "JavaScript origins" in the api access

Thank you for submitting the issue report. The JS Client does not currently support making requests from a file:// origin. I will file this issue as a feature request.

This is a hard block. It means you cannot run any HTML website localy in a device. I know the work-around is to create a local server, but it is like killing flies with a tank.

Do you guys have any date for this?

This is horrible. Can't do webview from Android!

For those who said that it can´t use it on a webview on Android, that´s not true, i´m using PhoneGap and it works just fine

i want to use it in a hta and i am getting the same error
which is pretty wonky as htas have all sorts of elevated privileges
pretty poor coding from google devs to need postMessage between frames for an api instead of using, like, i don't know... http requests, like an api is supposed to...

In your HTA are you able to directly access the API in question using CORS (either XDomainRequest and/or XMLHttpRequest)? See https://developers.google.com/api-client-library/javascript/features/cors if you would like more details on this process. If you try this please follow up to let us know whether it worked in your application.

The postMessage approach does work in some cases where CORS is not feasible (especially in pre-CORS browsers), but I understand that it might not work in your HTA. We are interested in using standard web technology where feasible, but I can't give any sort of prediction about when or whether gapi.client might switch to using CORS internally.
