Native Extension ClassNotFound

Hi,

I created a clean air native extension with a simple function that starts an activity from within the ANE, 'DumbActivity'. It worked.

However, after having DumbActivity extend YouTubeFailureRecoveryActivity in order to start using the YouTube API 3.0, I got a ClassNotFoundException on DumbActivity when I run the ANE.

Worth mentioning that when I run the code as a native android app, it runs properly, and I can use YouTube abilities. Also checked, the DumbActivity class is included in the Jar.

Is that some sort of library conflict or something?

Hi,

Have you created a platform-options-android.xml for android to include external jar(Youtube API), it should be like:

<platform xmlns="http://ns.adobe.com/air/extension/4.0">
   <packagedDependencies>
   <packagedDependency>youtubeapi.jar</packagedDependency>
   </packagedDependencies>
   <packagedResources>
   </packagedResources>
</platform>

You need to specify the name of the Youtube jar file name inside "PackageDependency" tag.


And, The adt command to package the ANE should be like:

adt -package [YOUR NORMAL OPTIONS] -platform Android-ARM -platformoptions platform-options-android.xml -C Android-ARM .



Please Verify.


Thanks,

Thank you! Now what am I doing when it bugs me about 'Namespace of platform-options-android.xml should match extension namespace.' ?

Oh the version on extension.xml is 3.1. should I state it as 4?
