My analysis and solution steps are as follows:
Error Description:
1. After the SDK manager is opened, the following error is reported when reload, or in the process of using, resulting in the failure to update the SDK
2. Click this connection, the browser can’t download
https://dl.google.com/android/installer_ r24.3.4- windows.exe
3. The error reported by the SDK manager is as follows
Cause Description:
1. Can’t connect dl.google.com , because the DNS did not resolve the address or the resolved address is wrong, resulting in the access timeout. (correct)
2. This link doesn’t need a ladder. The actual download speed is 10MB/s without setting. Don’t be misled
Solutions
Step 1, query an available IP address
http://ip.tool.chinaz.com/
Input dl.google.com
Step 2. Select one of the IP addresses and Ping the IP address on the console
(usually within 50ms)
3. Modify host
In this path, find the hosts file and open it with Notepad +
C:\Windows\System32\drivers\etc
Add the following, IP address with the one you Ping
203.208.50.69 dl.google.com
Save, close
4. Back to error description 2, if it can be downloaded, Congratulations, OK
