Hi,
regarding the Android 7.0 bug. This line solved the problem for me:
final Spatial model = assetManager.loadModel(resource.path);
if(model==null){
return -1;
}
SkeletonControl skeletonCtrl = model.getControl(SkeletonControl.class);
if(skeletonCtrl!=null) {
skeletonCtrl.setHardwareSkinningPreferred(false);// for Android 7 bug
}
Cheers!
Adi
