Native Extension for iOS

Question

I have downlaoded a 3rd party native extension for iOS. The ditribution provides the the source, ANE, and the native extension (*.a) file. I have added the ANE to the build path and see it referenced under the Native Extension tab under the iOS packaging (though I had to manually select the "Package" checkbox). I also have the extension.xml associated with the project and I can see the nartivelibrary *.a file referenced. However, I am not sure what I should so with the native library? Is there something I need to do to import or reference the file?

When I try to package the app for the iphone to I get an error saying that the implementation for the native extension <name of extension> was not found for the target platform. This is with the "Package" check box unselected under the Native Exrensions tab.

If I select the check box and then package for the iPhone, I get an exception "Error within Debug UI" and details of "java.lang.reflect.Inovation.TargetException".

Any ideas on what I am doing wrong?

All you need is the .ANE file. It works like a .SWC and should contain everything you need, including the .a file.

You need to add a few lines to your app descriptior XML:

<extensions> 
    <extensionID>com.company.extensionid</extensionID> 
</extensions>

The ANE should come with some documentation on what needs to go in there. If not, look in the extension.xml file for the correct extensionid.
