I was playing around in my phone settings when I found This. Look Middle left and there is a Pie with a lemon on top( I think) could that be a clue to what android L will be called???
There seems to be a lime on top. It might be a reference to how the last version would have been called Key Lime Pie, but ended up being changed to KitKat. You might be right though. Who knows?
According to the leaked SDK source code, the next Android release is touted to be codenamed Lemon Meringue Pie (LMP) after the delicious baked food that's usually served for dessert.
The code extract from the leaked SDK document further ascertains that the current preview builds of Android L meant for Nexus 5 and Nexus 7 are better known as "lmp-preview-release" that can be found in the SDK file located in the directory path: extras/android/m2repository/com/android/support/cardview-v7/21.0.0-rc1/cardview-v7-21.0.0-rc1.aar.
