Answer 2

The reason sudo works on linux and Mac OS X is that sometimes the permisions in ~/.android get misconfigured. If you are having this problem over and over again, and you would rather not type sudo every time you want to update your sdk, go to ~/.android and ensure that your account owns and has permissions to read and write all the files.

In my case I found that root owned several folders including the cache directory, cd ~/.android sudo chown -R <yourusername> * fixed the problem for me. If you are touchy about the security of your system, you can also specify a group like: sudo chown -R <yourusername>:<yourgroup> * AND

you could also specify the individual files and directories that need to be changed if you don't like the wild card. sudo chown --R <yourusername> cache for instance.

Thanks to the folks here for figuring it out.

And one more...the only thing working for me here on Windows 10 inside vmWare:

• Right click "This Computer"
• "Properties"
• "Extended system properties"
• "Environment Variables"
• Add a new key "ANDROID_SDK_HOME" and point it to "c:\users[username].android"

I solved this issue by adding ipaddres of my server in to Http:Proxy server and port number 80 And Sdk got updated withing fraction of second.

To get ip address of your proxy server Go to internet options Under connection tab > lan settings > check if Use automatic configuration script is checked> if its checked copy only ip address from address textbox and past it in Http:proxy server text box in sdk manager tools option :) .

good luck Happy coading

I have solved this by:

1. Giving full permissions to the sdk dir (Right Click->Properies->Security->Edit)
2. Checking the "Force https to http" and clicking on "Clear Cache" in the "Options" dialog window
