I had the same issue before. You can download a zip file of the components you need and manually install them in Eclipse. Follow this link - https://developer.android.com/sdk/installing/installing-adt.html#Troubleshooting
I know that this applies to Android Studio and not Eclipse, but in case someone stumbles across it:
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.
