将Libgdx项目从Eclipse迁移到Android Studio时出错

Question

我正在尝试将我现有的游戏(用libgdx编写)从Eclipse迁移到Android Studio.迁移我的桌面项目后正常工作,但我的Android项目有问题.在android我正在使用Admob广告.

我收到以下错误消息:

如您所见,Android Support Repository已安装

我的项目结构:

在Project Gradle文件中,我有这个:

    }

}

                }
            }
        }


    }
}

我试图将android支持更改为其他版本,但我得到同样的错误.

任何帮助,将不胜感激.

谢谢

最后我找到解决方案

我使用与之前的设置相同的包创建了空白的新 libGDX 项目libGDX project setup，并将所有类从旧项目复制到这个新项目。完成后，我得到了代码的工作版本。

我没有注意到 buld.gradle 作为评论和@piotrek1543答案提交的任何差异。

我不知道到底是什么问题，但我的项目现在可以工作了。

我希望这对将来的任何人都有帮助！
