更新了安卓SDK的tools之后发现打安卓包报如上述错误。google之后发现新的tools中android命令不能使用。

解决方案是去下载老版本的tools替换之后重新打包就可以解决。tools在SDK根目录下。实验发现25.2.3版本及以下都可以正常打包。

下载地址  SDK Tools r24.1.2版本的下载路径是：http://dl.google.com/android/android-sdk_r24.1.2-windows.zip

将r24.1.2修改为 想要的版本后即可下载。下载完把压缩包中的tools单独拉出来替换自己SDK根目录下的tools。（最好把自己的tools备份一下免得以后要用）。
