I right click on my project in eclipse, android tools , 'Rename application package'.
Pick any name and it will fail, directing you to the error log for details.
There i find the following:

Does this tool work for anyone? If so, please let me know what version of eclipse you are using.
I'm using the latest versions of eclipse (64bit) on windows 7 with the latest ADT eclipse plugin.
I was facing the same problem. I just was was not able to rename the package using package > right click > rename package. It appeared the package references in some xml templates, using custom controls were not updated, so the R file could not be generated. After looking at the xml and renaming the references, the R file was generated and I could continue renaming.
