a certain third-party jar's classes is missing after release build

[SangHee]

I'm building a native extension for the Android platform using several third-party jar files.

I exportd a jar file from Android project that include classes implementing the FREExtension interface.

And I merged A exported jar file and third-party jar files into a single jar file.

I package a ANE file and I build a APK file using a ANE file.

Strangely a certain jar's classes of the third-party jar files are missing in APK after release build.

( I am using Flash Builder 4.6. )

I changed a ANE file to .zip and check jar file using jd-gui tool.

This time I saw missing classes clearly.

I tried many ways but did not find a solution.

If anyone else know about this or experience this problem,

plese give me a advice.

Thanks.

The jar file which classes are missing in APK is the "sdk4game.jar".

Its package is "eu.inn.sdk4game".

The android-support-v4.jar is same.

I check android-support-v4.jar's classes in ANE.

But they are missing in APK after release build.

I don't know why.

I use Flash Builder 4.6 and Flex SDK 4.6.0 + AIR SDK 15.0.0.356.

Is there anyone else know about this???
