The final release of Android M won't be here until this fall, but the good news for developers and other adventurous users is that Google is distributing early developer preview builds for a handful of Nexus devices. The company tells us that it will provide Android M Developer Preview images for the Nexus 5 and Nexus 6 smartphones, the Nexus 9 tablet, and the Nexus Player set-top box. As with last year's L preview, that support list may expand for the final consumer release.
