Naming of previous versions of Android:
We all know that the historical names of the Android system are very interesting. The teacher of the Infinity Internet Android training below summed it up: Before the official release of Android, there were two internal test versions at the beginning, and they were named after the famous robot. Name them, they are: Astro Boy (AndroidBeta), clockwork robot (Android1.0). Later, due to copyright issues, Google changed its naming rules to use desserts as the code names of their system versions. Dessert nomenclature began when Android 1.5 was released. The size of the dessert represented by each version is getting bigger and bigger, and then in order of 26 letters:
