At Google I/O 2014 on Wednesday, after announcing Android L , the next version of Android, Google said that the developer preview will be made available the next day. As said, the Android L developer Preview is now available for the Nexus 5 and Nexus 7 (2013 Wi-Fi only) devices.
Google also released the SDK for the Android L and also Android Wear which indicates developers can work on their apps being compatible on Android L and also Android smartwatches.
Chet Hasse from Google mentioned that “Android L is a preview release where things work pretty well, but it’s not done yet.” So that indicates some features and functions might not be fully developed so we do not know how stable or reliable the developer preview is.
Knowledge improves by mutual sharing of information. So share it.
