因此手动通过迅雷下载如下安装包：
https://dl.google.com/android/repository/platform-tools_r28.0.0-windows.zip
https://dl.google.com/android/repository/platform-28_r04.zip
https://dl.google.com/android/repository/build-tools_r28.0.1-windows.zip
https://dl.google.com/android/repository/google_m2repository_gms_v11_3_rc05_wear_2_0_5.zip
https://dl.google.com/android/repository/emulator-windows-4848055.zip
https://dl.google.com/android/repository/3534162-studio.sdk-patcher.zip.bak
https://dl.google.com/android/repository/sdk-tools-windows-4333796.zip
https://dl.google.com/android/repository/android_m2repository_r47.zip
下载完成后逐个解压缩放入SDK目录，如下：
1、创建SDK目录，并copy上述文件到sdk目录
2、platform-tools_r28.0.0-windows.zip直接接受压缩到本地目录：Sdkuild-tools
3、platform-28_r04.zip解压缩后得到android-9文件夹，把android-9修改为android-28，放到本地目录：Sdkplatformsandroid-28
4、build-tools_r28.0.1-windows.zip解压缩后得到android-9文件夹，把android-9修改为28.0.1，放到本地目录：Sdkuild-tools28.0.1
5、google_m2repository_gms_v11_3_rc05_wear_2_0_5.zip解压缩后得到m2repository文件夹，放到本地目录：Sdkextrasgooglem2repository
6、emulator-windows-4848055.zip解压缩后得到emulator文件夹，放到本地目录：Sdkemulator
7、3534162-studio.sdk-patcher.zip.bak修改名称为3534162-studio.sdk-patcher.zip，解压缩后得到sdk-patcher，修改名称为patcher放到本地目录：Sdkpatcherv4
8、sdk-tools-windows-4333796.zip解压缩后得到tools文件夹，放到本地目录：Sdk ools
9、android_m2repository_r47.zip解压缩后得到m2repository，放到本地目录：Sdkextrasandroidm2repository
上述完成后重新启动Android Studio，创建项目时选择sdk指定到本地Sdk目录。Android Studio检查Sdk目录的文件并显示成功。
创建android app时，如果需要下载安装https://dl.google.com/android/repository/aiasdk-1.3.0-1525823131.zip，也可以使用类似方式，通过迅雷下载aiasdk-1.3.0-1525823131.zip包，然后解压缩得到sdk文件夹，修改sdk名称为instantapps，放到本地目录：Sdkextrasgoogleinstantapps
