There's plenty of indication that the next version of Android, dubbed project L for now, will actually be called "Lemon Meringue Pie". Google introduced the Android L framework with the new Material Design language, and now we are waiting on a retail build to hit the shelves, most likely debuted on an HTC-made Nexus 9 tablet first, with a 64-bit Tegra K1 processor, and allegedly 4 GB of RAM.
Meanwhile, a Lemon Meringue Pie Android build, codenamed LRW50D, has been noticed in the Chromium issue tracker. Ever since Android Cupcake, Android builds have carried such short internal titles, which follow their development chronologically. "L" here stands for the Lemon Meringue Pie in question, "R" is for the code branch that the build originates from, "W" indicates the third quarter of the year, and, finally, the number 50 are the days going into the quarter, which would peg the LRW50 release happening on August 19th, while "D" is the fourth edition for that same day.
The Build was runiing on the "New Nexus 7" which refers to the current Nexus (2013) from ASUS. Will this be the final Name for Android L ? Let's wait and see...
