Android App will not POST via AJAX

[Marcelo]

Hello,

I was automatically upgraded from Icenium Graphite (Windows 7) to AppBuilder today. Now, when I try to launch my Android app on device for testing (local USB connection) my ajax requests made with plain-ol Jquery are failing. I used the experimental debugger so I could see what was going on in the device and I get a 404 error when executing the XHR call (which I use for logging into my app).

I tested the exact same thing on the AppBuilder "Simulator" on desktop and on an iPhone device and it works fine. What is going on with my Android device? I am using Nexus 5 purchased directly form Google. Unfortunately, I have not been able to test on another Android device yet, but I strongly suspect this bug has something to do with the transition from Icenium to AppBuilder since things were working perfectly on Friday (when I last touched the app code).

Anyone else experiencing issues with and built and deployed for testing on Android???

Cheers,

Marcelo

Hi Marcelo,

Actually it sounds like you've hit a Cordova breaking change that was introduced in Icenium (now AppBuilder) as part of its previous release, namely:

Apache Cordova 3.1 introduces unified whitelist for Android. To reflect this change, the declaration of the whitelisting rules in the Android config.xml template in Icenium is changed to <access origin="*"/>.
If you have existing projects in which you have already manually modified Android config.xml, you might need to manually change the whitelisting rules declaration to <access origin="*"/>.

Please note that you should also rebuild and redeploy your app to the Nexus after this change. Let me know the name of your app if the problem persists.

Hello Hanna,

Can you confirm that you have enabled the INTERNET permission in your project's Android settings:
Project Properties for Android Devices

Without it, your app won't have access to the device's internet connection.
