I updated Eclipse with the new SDK tools (rev. 23), but now when Eclipse starts I receive the error:

Don't try to upgrade from previous version because it doesn’t work at all. If you have got problems with zipalign, it's now under build-tools and no more under tools/ so you can do a symbolic link or just copy it into the expected folder.
