安装android studio之后无法直接打开SDK manager

之前安装的android studio之后，SDK Manager和AVD Manager两个运行程序双击都打不开页面了，之前都是正常的，所以java环境变量的问题是不存在的。

SDK Manager本质上是执行tools目录下面的android命令，执行 tools/android 命令发现提示 The "android" command is deprecated.，百度了一下，果然发现Google将原来的SDK Mananger弃用了，官方建议的开启方式是，在Android Studio中打开tools>>SDK manager，见下图：

不过这样使用比较麻烦，所以查了资料，发现只要修改android sdk文件夹下的tools里面的android.bat文件内容就可以恢复成之前的形式。

首先备份下现有android.bat文件

然后替换成如下的内容：

保存之后，双击android sdk文件下的sdk manager就可以打开页面了：
