The Chromium issue tracker is often a good place to spot a new Nexus device or build of Android, and today appears to be our lucky day. Sported by a device known as the “New Nexus7” – make of that what you will – a certain build of Android has been spotted with build number LRW50D. We know it is Google convention to always start the build number with the letter of its code name, at this point suspected to be Android Lemon Meringue Pie. What follows is usually a series of unique identifiers that let us know exactly when the build was created. In this case, it appears the build is from the 19th of August, 2014 and is the fourth version of the build that day. Naturally, the date isn’t an exact science due to some code inheriting dates, but it’s definitely in the right ballpark.
The “New Nexus7” part of this story is probably of no consequence – this is most likely just the 2013 Nexus 7 – however it’s clear that it was running some form of Android L when this issue was made. Myce.com, who found this issue, also notes that numerous references to “lmp-dev” were made in the code; we know that “lmp” is also referenced within the Android SDK itself, which originally gave birth to the Lemon Meringue Pie rumours.
