packageName question when building an Android ANE

Question

Hi,
I'm trying to implement an external library ANE wrapper for Android.
I'm always receiving "class not found" error message in LogCat. No problem accessing native code, but when I try to access to external library functions it fails.
I've tried
External library inside Air native extension for android
How to include additional Jar in Android Native Extension for Adobe Air Mobile - Stack Overflow
Unsuccessfuly.
Reading these docs: Adobe Flash Platform * Including resources in your native extension package I think I could have a problem loading the resources and, because of that, not access to the class properly or crashing somewhere.
My platformoptions file
<platform xmlns="http://ns.adobe.com/air/extension/17.0">
    <packagedDependencies>
        <packagedDependency>my_sdk.jar</packagedDependency>
    </packagedDependencies>
  <packagedResources>
  <packagedResource>
  <packageName>com.my_sdk</packageName>
  <folderName>res</folderName>
  </packagedResource>
  </packagedResources>
</platform>
My question is, how can I know the "packageName", "res" is the folder where I copied and pasted all the resources from the external library, but the package? I've just written randomly "com.my_sdk"
Thanks!

To create Android ANE there is a devnet article Developing and using Adobe AIR native extensions for Android devices | Adobe Developer Connection
Accessing third-party native libraries
The original purpose of native extensions was to provide access to native platform features that were not currently covered by the ActionScript API. However, many ActionScript developers targeting Android have expressed a strong interest in taking advantage of available third-party Android libraries that package together a number of popular Android-specific functions, so that they need not reimplement those functions in ActionScript. To use any third party library jar in your project you can use the R* mechanism. For more information, see Developing Native Extensions Guide.
Working with arbitrary assets
In addition to accessing Android native resources, developers often need to access arbitrary resources for assets such as drawables and sound files. These assets are frequently found packaged in arbitrary dependent JAR files instead of a central location, especially for third-party native libraries. To use such assets in your project you can use the R* mechanism. For more information, see Developing Native Extensions Guide.
