Unable to create android .apk with SDK revison 23

I’ve tried doing some research into the issue and I’ve seen people having issues with the 22nd revision of the Android SDK. More specifically this link said to downgrade my android sdk to revision 21 with the provided link. Unfortunately the link they provided isn’t up anymore, and I can’t find a mirror anywhere.

If the issue is not with the 23rd revision, but something I haven’t downloaded in the SDK manager, please help me as well.

If the issue you are experiencing is similar to this one: Error on android game building, Win32Exception: ApplicationName='F:/Android SDK\tools\zipalign.exe', CommandLine='4 - Unity Answers

The solution is to upgrade to Unity 4.5.2 if you are using 4.5, there was a bug with SDK 23.
