android上大气被裁减掉，有人遇到过没

成功编译运行osgearth到android上，发现其他的还ok，但是大气始终显示不出来，不知道什么原因，pc上正常的。
大神建议看源码写渲染测试，硬啃之前，想问问有人遇到过没？

我的代码如下：
osgEarth::Map *map = new osgEarth::Map();
        createImageLayers(map);
        _mapNode = new osgEarth::MapNode(map);
        _viewer->setCameraManipulator(new EarthMultiTouchManipulator());
        EarthMultiTouchManipulator* manip = dynamic_cast<EarthMultiTouchManipulator*>(_viewer->getCameraManipulator());
        osgEarth::Util::EarthManipulator::ActionOptions options;
        manip->getSettings()->setMouseSensitivity(0.30);
        manip->getSettings()->setThrowingEnabled(true);
        manip->getSettings()->setThrowDecayRate(0.1);
        manip->getSettings()->setLockAzimuthWhilePanning(false);
        manip->getSettings()->setArcViewpointTransitions(false);
        manip->getSettings()->bindTwist(osgEarth::Util::EarthManipulator::ACTION_NULL, options);
        manip->getSettings()->bindMultiDrag(osgEarth::Util::EarthManipulator::ACTION_NULL, options);
        manip->getSettings()->setMinMaxPitch(-90.0, -90.0);

       osgEarth::Util::SkyOptions sOptions;
        sOptions.ambient() = 1.0;
        osg::ref_ptr<osgEarth::Util::SkyNode> sky = osgEarth::Util::SkyNode::create(sOptions, _mapNode);
        sky->setDateTime( osgEarth:ateTime(2011, 3, 6, 12.0) );
        sky->attach(_viewer, 0);
        if ( _mapNode->getNumParents() > 0 )
        {
                osgEarth::insertGroup(sky.get(), _mapNode->getParent(0));
        }
        else
        {
                sky->addChild( _mapNode );
        }
        osg::Group* root = new osg::Group();
        root->addChild(sky);

osg::Material* material = new osg::Material();
        material->setAmbient(osg::Material::FRONT, osg::Vec4(0.4,0.4,0.4,1.0));
        material->setDiffuse(osg::Material::FRONT, osg::Vec4(0.9,0.9,0.9,1.0));
        material->setSpecular(osg::Material::FRONT, osg::Vec4(0.4,0.4,0.4,1.0));
        root->getOrCreateStateSet()->setAttribute(material);
        root->getOrCreateStateSet()->setMode(GL_LIGHTING, osg::StateAttribute::OFF | osg::StateAttribute::OVERRIDE);
        root->getOrCreateStateSet()->setAttribute(_viewer->getLight());

        _viewer->setSceneData(root);

        _viewer->realize();
