Android Development || Android Development History

Android development refers to the production of the application on the android platform. Android was founded by Andy Rubin, the father of Android.

In 2005, Google acquired the high-tech enterprise Android, which was established only 22 months ago, and launched SMS and mobile search. 

Positioning and other services, the general platform based on Linux entered the development.

Software development needs to master the knowledge system: Unix/Linux platform technology, enterprise-level database technology, Java language core technology, software engineering and design patterns, Android application development foundation, Internet core technology, Android system-level development, JavaEE core technology.

In the domestic mobile phone market, the Android operating system has occupied a market share and is the undisputed king.

Bringing very strong demand to the market, Android development engineers are undoubtedly hot posts on the recruitment website. The first question facing development enthusiasts is how to master the Java language.

Among the languages ​​popular in the market, the Java programming language is a simple grammar, but the object-oriented ideas included are profound and profound.

Introduction

 

Google officially announced the operating system on November 5, 2007. In 2008, Patrick Brady gave a lecture on "Anatomy & Physiology of an Android" on Google I/O and proposed the Android HAL architecture.

HAL exists in the form of *.so files, which can separate the Android framework from the Linux kernel.

Name source

The word "Android" first appeared in the science fiction "Future Eve" published by the French writer Lier Adam in 1886. He named the machine like a human being as Android.

On February 3, 2010, Linux kernel developer Greg Kroah-Hartman removed the Android driver from the Linux kernel "state tree" ("staging tree"). From then on, Android and Linux core development parted ways.

Android introduction

Android is an open source mobile operating system based on Linux developed by Google. It includes the operating system, user interface, and applications—all the software that mobile phones need to work, and there are no proprietary barriers that have previously hampered innovation in the mobile industry.

Google has partnered with the Open Handset Alliance to develop Android, a consortium of more than 30 technology and wireless applications including China Mobile, Motorola, Qualcomm, HTC and T-Mobile.

Through deep partnerships with operators, equipment manufacturers, developers and other interested parties, we hope to form an open ecosystem within the mobile industry by establishing a standardized, open mobile phone software platform.

We believe this move will promote better and faster innovation and provide unpredictable applications and services to mobile users.

As an important part of Google’s corporate strategy, Android will further advance the corporate goal of “providing information to everyone, anytime, anywhere”.

We have found that many mobile phone users around the world have never used any Android-based phones. Google's goal is to make (mobile communications) independent of devices and even platforms.

For this purpose, Android will complement, and will not replace, Google's long-standing mobile development strategy: develop a useful and attractive mobile service by partnering with handset manufacturers and mobile operators around the world. And promote these products.

The establishment of the Open Handset Alliance and the launch of Android are major changes to the status quo, and require considerable patience and high investment before bringing initial benefits.

However, we believe that the potential benefits that global mobile users can derive from it are worth the effort. If you are also a developer and interested in our ideas, please give us another week, when Google will be able to provide the SDK.

If you are a mobile user, just wait a little longer and some of our partners plan to launch a phone product based on the Android platform in the second half of 2008.

If you already have a phone that you know and love, make sure you have Google Maps for mobile, Gmail, and other great apps for your phone. Google will continue to work hard to make these services even better, while also adding more attractive features, applications and services.

Development History

In October 2003, Andy Rubin and others created Android and formed the Android team.

On August 17, 2005, Google acquired a low-key Android company and its team that was only 22 months old. Andy Rubin became vice president of engineering at Google and continued to be responsible for the Android project.

On November 5, 2007, Google officially showed the operating system called Android, and on this day Google announced the establishment of a global alliance organization consisting of 34 mobile phone manufacturers, software developers, The telecom operator and chip makers are formed together with 84 hardware manufacturers, software developers and telecom operators to form the Open Handset Alliance to jointly develop and improve the Android system. This alliance will support Google's release. Mobile operating system and application software, Google released the Android source code with the Apache free open source license.

In 2008, at the Google I/O conference, Google proposed the Android HAL architecture map. On August 18 of the same year, Android was approved by the Federal Communications Commission (FCC). In September 2008, Google officially released Android 1.0. System, this is also the earliest version of the Android system.

In April 2009, Google officially launched the Android 1.5 mobile phone. Starting with the Android 1.5 version, Google began to name the Android version as a dessert, and Android 1.5 was named Cupcake. The system has been greatly improved compared to Android 1.0.

In September 2009, Google released the official version of Android 1.6, and launched the mobile phone HTC Hero (G3) with the official version of Android 1.6. With its excellent design and new Android 1.6 operating system, HTC Hero (G3) became the most popular mobile phone in the world at the time. Android 1.6 also has an interesting dessert name called Donut.

In February 2010, Linux kernel developer Greg Kroah-Hartman removed the Android driver from the Linux kernel "state tree" ("staging tree"). From then on, Android and Linux development mainstream will part ways. In May of the same year, Google officially released the Android 2.2 operating system. Google named the Android 2.2 operating system Froyo, translated as frozen yogurt.

In October 2010, Google announced that the Android system reached its first milestone, that is, the number of Android applications that have obtained official digital certification in the electronic market has reached 100,000, and the application of Android system has grown very rapidly. In December 2010, Google officially released the Android 2.3 operating system Gingerbread (Gingerbread).

In January 2011, Google said that the number of new Android devices per day reached 300,000. By July 2011, the number had increased to 550,000, while the total number of Android system devices reached 135 million. The Android system has already become the most occupied system in the smart phone field.

On August 2, 2011, Android phones accounted for 48% of the global smartphone market and dominated the Asia-Pacific market, ending the dominance of Symbian (Saipan System) and ranking first in the world.

In September 2011, the number of applications for the Android system has reached 480,000, and in the smartphone market, the Android system has reached 43%. Continue to rank first in the mobile operating system. On September 19th, Google will release a new Android 4.0 operating system, which is named "Ice Cream Sandwich" by Google.

On January 6, 2012, Google Android Market has 100,000 developers launching more than 400,000 active apps, most of which are free. The Android Market app store directory exceeded 400,000 benchmarks in the first week of the New Year, only 4 months away from the 300,000 app. In the early 2011, it took four months for the Android Market to increase from 200,000 to 300,000 applications.
