Having promised monthly updates to Android M at the Google I/O 2015 conference earlier this year, the Developer Preview of the latest version of Android has received its first update.
Preview 2 includes the new platform code, some additional APIs for testing as well as a few developer reported fixes such as Camera Permission and TextInputLayout issues.
How to Get the Update
If you are already running the M developer preview launched at Google I/O (Build #MPZ44Q) on a supported Nexus device (e.g. Nexus 5, Nexus 6, Nexus 9, or Nexus Player), the update can be delivered to your device via an over-the-air update. It is expected that all devices currently on the developer preview will receive the update over the next few days.
There’s also a new version of the Android M Developer Preview posted here for any new fresh installs for devices.
Google indicates that Android M is still on schedule for a fall release and urges anyone on the Developer Preview to report critical issues as you continue to test and validate your apps on the M Developer Preview.
