title: Facebook mobile web application started throwing API Error Code:196
body: <p>I have a web application which is configured as a canvas web application in facebook and also has provided a mobile url where mobile specific page is served from the web server.  Application has been running for about 3 months and starting last week (I believe the issue started last week, there was no application deployment for the last 3 months ) when I access the application from my android phone , from the apps short cut in the native android facebook application , facebook throws the below error</p>
  
  <p>API Error Code:196
  API Error Description: Cannot redirect to desktop web canvas URL on a mobile device.
  Error Message : redirect_uri is not owned by this application.</p>
  
  <p>I can see that the request is coming to my web server and after I send the redirect url to the mobile, it throws the above error.</p>
  
  <p>Since there was no code changes, I'm a bit confused about this new error, and googling this api error number didn't return any hits except for one japanese website where someone has mentioned about this error last week, but don't see any solutions.</p>
  
  <p>The error message "cannot redirect to desktop web canvas..." seems to be sort of self explanatory but I can't figure out what is wrong , especially since the samething was working before, unless FB has changed any of their code which introduced a new issue or exposed an existing issue in my application configuration.</p>
