以上是之前没有配置过虚拟机的情况下，此时.android目录下还没有虚拟机，如果之前已经添加过虚拟机，那么在
.android/avd下就会有虚拟机，此时就需要将每个虚拟机的配置文件ini文件进行修改
修改.AndroidStudio位置
关掉Android Studio。来到其安装目录下bin-idea.properties文件，打开
然后将下面idea.config和idea.system开头的两行注释打开，并修改为自己的.AndroidStudio文件所在的位置，修改后保存。
注意：
1.这里的.AndroidStudio目录是.AndroidStudio3.5所以在修改路径时也要是.AndroidStudio3.5，默认打开注释后是.AndroidStudio，所以要根据自己原来C盘下的.AndroidStudio的名字进行修改。
2.这里的D:/Android目录不能是AndroidStudio的安装目录，否则会报错。
修改.gradle位置
首先将C盘下的.gradle目录复制到要另一目录。
然后此时启动AndroidStudio，注意此时先不要删除原来的C盘的目录，AS刚启动还会找原来的位置。
启动后File-Settings-Gradle
然后将gradle位置修改为正确位置。将原来C盘的删掉，重启Android Studio
注意：
最下面的位置是全局设置gradle的位置。上面的Offline work不要勾选，否则就是离线模式。
上面中间的勾选使用默认的，如果勾选使用本地的gradle，如果没有对应版本会报错。
最上面实现保存，不用每次都设置。
