Sometime you need to add proxy setting in your SDK Manager GoTO->Windows->SDK Manager->Tool->Otions There give SERVER: proxy and PORT:8080

Answer 3

I got the solution for the Android Studio installation after trying everything that I could find on the Internet. If you're using Android Studio and getting this error:

Find [Path_to_Android_SDK]\sdk\tools\android.bat. In my case, it was in C:\Users\Nathan\AppData\Local\Android\android-studio\sdk\tools\android.bat.

Right-click it, hit Edit, and scroll all the way down to the bottom.

Find where it says: call %java_exe% %REMOTE_DEBUG% ...

Replace that with call %java_exe% -Djava.net.preferIPv4Stack=true %REMOTE_DEBUG% ...

Restart Android Studio/SDK and everything works. This fixed many issues for me, including being unable to fetch XML files or create new projects.

Answer 4
