Making the Google Mail Chrome app work with mail on your domain in Google AppEngine

More recently, a note appeared that the next dev-build of Google Chrome began to support Chrome Apps. Undoubtedly, this is good news, only the Google Mail application by default only works with standard @ gmail.com mail , and it has no settings. This problem is easy to fix.

Find the manifest.json file that corresponds to the application (in ubuntu, it lies in the / opt / google / chrome / resources / gmail_app directory). Now in this file you need to replace the value of web_url from the standard one to mail.google.com/a your_domain / .
If you want the browser to open a tab with the application when clicking on any link to mail in your domain, right after the line

"urls": [

add line

" *: //mail.google.com/a/ your_domain / ",

Under the cut version of manifest.json "before" and "after".

manifest.js before editing:
