targetController.SourceType = ImageTargetController.DataSource.Target;
Optional<ImageTarget> fromImageFile = ImageTarget.createFromImageFile(path, StorageType.Assets, name, "", "meta",0.1f);
targetController.TargetSource = fromImageFile.Some;
这个方法是这么使用的么?为什么控制台一直报Error: invalid trackable 14: 2222错?
