Overview Edit
The word Android first appeared in the science fiction of "Future Eve" published by French writer Virie-de-Lille Adam in 1986, and the author Lille Adam named Android as a human-like machine. This is the origin of the android villain name. [1]
The Android operating system is a mobile device operating system developed by Google and the Open Handset Alliance, and its earliest version of Android 1.0 beta was released on November 5, 2007 and has been released with multiple updates to date.

Android Publishing History
These newer versions have fixed bugs on the previous version and added new features that were not available in the previous version.
There were two pre-release builds of the Android operating system, which were codenamed Astro Astro (Astro) and Clockwork Robot (Bender). Due to copyright issues, since May 2009, the Android operating system changed to dessert as a version code, these versions are named in the order of uppercase letters.
Here is the dessert code and translation:
Cupcake: Cupcakes
Donut: Donuts
Éclair: Lightning Puff, French cream sandwich dessert, muffin
Froyo: Frozen Yogurt
Gingerbread: Ginger Cake
Honeycomb: Hive
Ice Cream Sandwich: Ice Cream Sandwich, ice cream sandwich
Jelly Bean: Jelly bean
KitKat: Kit Kat chocolate bar
Lolipop: Lollipop
Marshmallow: Cotton Candy
Development Code Editor
Before the official launch, Android had two internal beta versions, and named them by famous robot names, namely: Astro Astro (Astro Boy, note not Astro Astro) and Clockwork Robot (Bender). It is important to note that Android 1.0 and 1.1 are not the two versions, and the "Android version history" entry in Wikipedia is not part of the error. [3]
Later, due to copyright issues, Google changed its naming convention to use dessert as the code name for their system version. Android 1.0 was released on September 23, 2008 in the first edition of Android, Android 1.1 released on February 2, 2009, but in fact, Google has more than the 1.1 version of the variant. The dessert nomenclature began in the third edition of Android 1.5 (actually the fourth edition, since Android 1.0 actually has two versions). Starting with the Android 1.6 Donut Donut, the project team formally determined that the first letter of the Android Development Code would continue from "C". It is worth mentioning that the internal code for Android 1.1 is Petit four, but the project manager liked the delicious dim sum, which eventually ended the naming method.
So Astro boy and Bender were real, but they went with the super-early milestone builds. The complete timetable is this:

Android logo designer Irina Blok: This logo is to represent the international Android, and is open source, without reference to any cultural role, we have a simple conversation with the Android developers and then study all the Android/robot theme, Then listed, select A, then fine to the pixel, the reality of the cartoon image, it is only the Android spirit of the most basic embodiment. [4]
The core of the Android logo design is to embody the spirit of the product, the perspective of open source, the concept of direct developer-oriented, to achieve the same effect as the Linux Penguin logo.
Finally proved that the logo came out after the developer and the user's strong resonance, but before Google itself is willing to leave the design on the desk to make employees as picky as possible, so in the Google internal release of the source design, a variety of Google engineers are there to put their own views on color, Finally Blok selected green is the PMS 376C, #A4C639十六进制, because this represents the nostalgic code color, and in the black background is very conspicuous.
