因此手動通過迅雷下載如下安裝包：
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
下載完成后逐個解壓縮放入SDK目錄，如下：
1、創建SDK目錄，並copy上述文件到sdk目錄
2、platform-tools_r28.0.0-windows.zip直接接受壓縮到本地目錄：Sdk\build-tools
3、platform-28_r04.zip解壓縮后得到android-9文件夾，把android-9修改為android-28，放到本地目錄：Sdk\platforms\android-28
4、build-tools_r28.0.1-windows.zip解壓縮后得到android-9文件夾，把android-9修改為28.0.1，放到本地目錄：Sdk\build-tools\28.0.1
5、google_m2repository_gms_v11_3_rc05_wear_2_0_5.zip解壓縮后得到m2repository文件夾，放到本地目錄：Sdk\extras\google\m2repository
6、emulator-windows-4848055.zip解壓縮后得到emulator文件夾，放到本地目錄：Sdk\emulator
7、3534162-studio.sdk-patcher.zip.bak修改名稱為3534162-studio.sdk-patcher.zip，解壓縮后得到sdk-patcher，修改名稱為patcher放到本地目錄：Sdk\patcher\v4
8、sdk-tools-windows-4333796.zip解壓縮后得到tools文件夾，放到本地目錄：Sdk\tools
9、android_m2repository_r47.zip解壓縮后得到m2repository，放到本地目錄：Sdk\extras\android\m2repository
上述完成后重新啟動Android Studio，創建項目時選擇sdk指定到本地Sdk目錄。Android Studio檢查Sdk目錄的文件並顯示成功。
創建android app時，如果需要下載安裝https://dl.google.com/android/repository/aiasdk-1.3.0-1525823131.zip，也可以使用類似方式，通過迅雷下載aiasdk-1.3.0-1525823131.zip包，然后解壓縮得到sdk文件夾，修改sdk名稱為instantapps，放到本地目錄：Sdk\extras\google\instantapps
