We've received quite a few emails in the last 24 hours excitedly pointing to the following tag in the Nexus 5's repository on the Android project as evidence Google plans to bring Android N to the phone. Specifically, there is a tag in the Nexus 5 repo called "android-n-preview-1" - which many are taking to be a signal that Google is actively developing Android N for the Nexus 5.

Unfortunately, such interpretations are not supported by the existence of this tag. As a result of the tools Google uses as part of building Android, pretty much any device that is currently supported (note that current support does not mean future support) by Google will generate tags for new versions of the operating system regardless of whether or not they'll actually get them.
