Rumours originally claimed that the next android version will have the codename LIME PIE and it will be android version 5.0. It just turned out that those rumours are not correct and that the next android version will be 4.4 with codename KITKAT (KitKat is the trademarked name of the candy bar made by Nestle)
Let's hope that someday google will come to naija and codename android QUILI QUILI I've compiled a list of all previous android versions, their codenames and release dates.
