Here's some background 1st:
I'm trying to do a proof-of-concept Android application that will check if I can send some APDU commands to a SIM card applet and process the response.
I'm using SEEK for Android as a reference implementation of Open Mobile API.
The application should work on Samsung Galaxy S3 smartphone which comes with Open Mobile API, as stated here.
I am not allowed to use a custom ROM, nor do any modifications to Android source.
What I have done so far:
- I've downloaded Android API lvl 18 with Open Mobile API and Open Mobile API packages.
- I've created a sample application that should try to access an applet on my SIM card, as described here.
On button click, I'm getting SecurityException

I believe I don't have something set up right on my SIM card regarding applet access, but since that part is not my domain, I don't know what to do to fix this.
I've ran into this discussion on Google Groups that sound similar to my predicament, but I'm not sure how to interpret it.
Any help is appreciated!
