This seems to be a common problem but I've been searching the internet for awhile and I none of the many solutions seem to work. Here are the errors that are output by either eclipse or running android.bat in a cmd window.
[2014-02-01 19:36:45 - SDK Manager] [SDK Manager] The system cannot find the file specified.
[2014-02-01 19:36:45 - SDK Manager] [SDK Manager] Error: Error parsing the sdk.
[2014-02-01 19:36:45 - SDK Manager] [SDK Manager] Error: com/google/common/collect/Maps
[2014-02-01 19:36:45 - SDK Manager] [SDK Manager] Error: Unable to parse SDK content.
So how fix?
