App fails to connect to API/ Install but does not run

Hello everyone,


I am building an app for blackberry devices using HTML 5 with Webworks SDK. I pull data from an API, the domain of which is set in my config file. So far development is going great and the app runs without a glitch on my Ripple Emulator. Now when I package and sign the app and install it both on a Blackberry Simulator and a Physical Blackberry device this is what I experience:


Blackberry Simulator:

The app installs and loads, but fails to connect to my API, hence even the simple login does not work. When I output the responses I get an internal server error. But this same code works on the Ripple Emulator with actual expected payload on every call.


Physical Blackberry Devices:

The app installs but does not run. But it is the same package as was installed on the Simulator


So I am wondering, is there anything I may be missing out or anything I need to set in place. Do I need to get a new app signing key? Or a different SDK version?.


Does anyone know what I can do next. I have been told that it is not an issue with the signing keys.

Re: App fails to connect to API/ Install but does not run

You do not need to sign an application to run it on a simulator.  However you DO need to sign it to run on a live device.


Are you correctly whitelisting the domain in your config.xml file?  Make sure you have something like this:

<!-- whitelist all domains -->
<access uri="*" subdomains="true"/>

<!-- whitelist a specific domain -->
<access uri="http://www.MYURL.com" subdomains="true"/>
