Several FXG - Error #2136 no valid data in swf file

Hello,

I have problem with a flex mobile project with 72 FXG files created with Illustrator CS6.

When I insert some FXG in the project the building is ok but if I run on Android air simulator, show me  an Error #2136 no valid data in swf file.

My code is like this:

<s:Application

  ...

  xmlns:comps="comps.*">

<comps:MyGraphicComp id="graphic1"/>

I tried embebbed the FXG files in SWC libraries but I obtained the same error.

I use Flash Builder 4.7 (64 bits) and Apache Flex SDK 4.16.1 AIR version 29.0.

any idea?

Many thanks

Dan
