Android was not originally a mobile phone system


Earlier this year, Android's father Andy Rubin said at a conference that the original purpose of developing Android was to develop a camera platform, but then Android was transformed into a mobile phone because of the explosive growth of smartphones. Operating system. Google acquired Android in August 2005, and Rubin joined Google.




Not optimistic after the announcement


On November 5, 2007, Google officially announced an operating system called Android, and announced the establishment of the Open Handset Alliance, which is operated by 34 mobile phone manufacturers, software developers, and telecommunications companies. Manufacturers and chip manufacturers together. The alliance will support Google's mobile operating system and application software, and will jointly develop open source code for the Android system.




But at the time Saipan, Blackberry, Palm and Windows Mobile were the main operating systems in the industry, and Apple only released the first generation of iPhone. Most people think that Android will not do much. At the time, a Nokia spokesperson said that they did not regard Android as a "threat", and a Windows Mobile manager of Microsoft said he "does not understand that Android can have How big is it."


The world's first Android phone


In October 2008, the world's first truly "Android phone" - HTC Dream (G1) came out. It is equipped with a 3.2-inch capacitive touch screen, processor and other configurations, retaining the QWERTY side-sliding full keyboard, which was still very advanced at the time.

This is also the first time that the Android system really appears on the hardware, which integrates a large number of Google services and built-in software stores; at this time, Apple has just released iPhone OS 2.0, AppStore came into being, and the Android iOS war is about to start.

According to a 2013 data set, Android has 1 billion active users in 5 years, making it the fastest growing operating system. In contrast, it took Apple six years to have 700 million users, while Saipan had 450 million users for 11 years.




Not long ago, data research institute IDC said that the sales of Android phones in the global market will reach about 85% in 2018. In the next five years, sales of Android phones are expected to reach a compound annual growth rate of 2.4%, and will reach 1.41 billion by 2022.


Transitional two upgrades


The Android system has been updated by more than ten major versions so far, and each upgrade makes the experience better and the UI look better. In so many versions of the change, Xiaobian thinks that the two most important updates are Android 4.0 and Android 5.0.

Android 4.0 unifies all the features of the previous 2.3 and 3.0, optimizing the system UI and adding smoother animations. In addition, Android 4.0 also has the ability to adapt to the interface on different sizes of devices. Starting with Android 4.0, Android is no longer a pure "mobile operating system"



Android 5.0 is the first 64-bit Android system, and the first system to support OpenGLES 3.1, with special emphasis on graphics performance. It is also the first show of Google's "Material Design" UI style. In addition, Android 5.0 opens the art mode by default. Although the storage space occupied by the app will increase a part, the running speed and smoothness are greatly improved.

I believe many of my friends will think of a green robot pattern when they mention Android, and this is the logo of Android. This image was designed in 2007 by the then Google designer Irina Blok, and the source of inspiration is said to be the male and female logo on public toilets.

In addition, Android has a unique naming scheme, and each major version is named after a Western-style dessert. But Android 1.0 did not actually have a real code name. Until Android 1.1 in 2009, it was called "Petit four" (a French dessert) inside Google, so from Android 1.5 "Cupcake" (cookies), Google began to officially use dessert to name the version, and started The letters are in alphabetical order.




The version names starting with Android 1.5 are:


Cupcake Cupcake (Android 1.5), Donut Donut (Android 1.6)

Muffin (Android 2.0/2.1), Frozen Yogurt (Android 2.2), Gingerbread (Android 2.3)
