ResourceNotFoundException error when accessing image in Android Titanium module - titanium

Question

I'm developing an Android Module for a Titanium app and I have to generate a Notification. Android SDK forces me to do a setSmallIcon() call to include a png asset as icon for the notification. I've put icon_notification.png asset in /platform/android/res/drawable folder of my module and (tryed to) got it in the code calling
TiRHelper.getResource("drawable.icon_notification")
but when I build module calling ant, the following error is raised:
[javac] Note: [KrollBindingGen] Running Kroll binding generator.
[javac] Note: [KrollBindingGen] No binding data found, creating new data file: org.appcelerator.titanium.bindings/connecthings.json
[javac] Note: [KrollBindingGen] Found binding for proxy Beacon

[javac] Note: /Users/***/Development/***/modules/android/***/android/src/***/***/ti/***/BeaconProxy.java uses or overrides a deprecated API.

seems that raising a ResourceNotFoundException exception, builder doesn't find the assset
Have I placed the file in the wrong place?

Answer 1

The platform folder also has to sub-folder of android folder.The full directory is "android/platform/android/res/drawable/". You can also check if the resources are created in the build folder.

Answer 2

Error posted is trowed during build step of the module.
In this step I think that resources are not already put in place, so, wrapping the TiRHelper method in a try...catch statement as written in the wiki suggested by #Saeed Sharman resolve the problem.
So, the working version is simply:
try {
TiRHelper.getResource("drawable.icon_notification");
catch (ResourceNotFoundException e) {
...
}
