Before the official release of Android, there were two beta versions at first, named after famous robots, namely Astro Boy and Bender. It should be noted that the version codes of Android 1.0 and 1. 1 are not these two, and the entry of "Android version history" in Wikipedia is wrong.

Later, due to copyright issues, Google changed the naming rules to use dessert as their system version code. Android 1.0 was the first version of Android officially released on September 23rd, 2008. Android 1. 1 was released on February 2nd, 2009, but there are actually more variants of 1. 1 in Google. The dessert naming method started from the third edition of Android 1.5 (actually, it is the fourth edition, because there are actually two versions of Android 1.0). Starting with Android 1.6 Donut doughnut, the project team officially decided to continue the initial letter of Android development code starting from "C". It is worth mentioning that the internal code name of Android 1. 1 is Petit Four, but the project director likes delicious snacks and finally ended this naming method.

So Astro Boy and Bender are real, but they are related to ultra-early landmark buildings. The complete timetable is as follows: Android landmark buildings (Astro Boy and Bender are floating somewhere here.
