Industry Background:
Today, involved in the communication industry chain every link, there is Android figure, Android is the first completely complete the entire communication industry chain operating system, mobile phone solutions, integrators, operators, content providers, users, are playing Android, Are amazed at the explosive growth of Android, Android now has more than 500,000 new Android devices enabled every day.
With the expansion of the Android platform, causing the Android talent shortage, the future talent demand gap will reach millions. But qualified androidproject is a handful, enterprise recruitment difficult to imagine. According to the Beijing News and other media reports Androidproject a year of experience monthly salary of 8000 yuan, on the micro Bo Kai-Fu Lee said students transfer Android software development. We believe that in the next few years, Android development project will be one of the hottest jobs in the 3G industry.
What is android:
Android is a Linux-based open-source operating system that is primarily used in portable devices. There is no uniform Chinese name, and more people in mainland China use Android (unofficial) or Ann (official). The Android operating system was originally developed by Andy Rubin, initially primarily supported by mobile phones. It was funded by Google in 2005, and has been developed and improved by a number of manufacturers to form an open cell phone alliance, gradually expanding into tablets and other areas. At the end of 2010, Android, which has only officially launched its two-year operating system, has overtaken Nokia's Symbian system, the world's most popular smartphone platform, to dominate the decade. industry Salary:
must learn Android for:
Faster pay promotion channels better top jobs Many other industry talent needs the hottest new technology industry
According to the Beijing News and other media reports Androidproject one year work experience monthly salary of up to 8000 yuan. Kai-Fu Lee on the Micro-blog on the students to transfer Android software development. Shang graduated students pay a maximum of 16000 yuan/month (after tax), the minimum 3000 yuan/month (in college), the average starting salary of 4828.84 yuan/month.

Android Development Overall Roadmap:
Basic Learning--javase:
a lot of friends started to learn Android, seems to be too anxious some. Android application development is based on the Java language, so there is no solid basic knowledge of Java, just mechanical copy of other people's code, is no matter what the meaning. So what is the extent of Java learning to be a cross-border? The following Java Basic (javase) syntax knowledge must be fully mastered.

Basic Learning Extension--javaee:
because very many Android applications require server-side support, it is necessary to master some of the server-side development knowledge. Java ee:ssh-struts+spring+hibernate. The advantages of such technology are complete and powerful, have been used for many years, and traditional Internet applications, most of which are made of Java for its construction platform, which allows a large number of content providers can be high-speed learning into the Android product development, And can be based on their own content features a lot of other focus on interactive design and UI expressiveness, greatly reducing the development cycle of mobile Internet applications.

Basic Learning Expands--linux Foundation:
Android is a Linux-based open-source operating system, in the future to learn and work in which we will deal with the Linux command, it is necessary to add some liunx basic knowledge.

Android Development Learning--Basic Theory: System Architecture Analysis:
The Android system has a total of 4 layers from the bottom up and each layer encapsulates the underlying implementation and exposes the calling interface to the previous layer.
| |
1. Linux kernel (Linux Kernel)
android performed on Linux Kernel 2.6, but replaced the Linux-bound part of the GNU protocol so that the Android program could be used for commercial purposes. The Linux kernel is the abstraction layer between the hardware and software layers.
2. Middleware middleware consists of two parts: the
Core library and the execution time (libraries & Android Runtime) Core Library contains , Surfacemanager display System Management Library, responsible for the display of 2D or 3D content to the screen; Media Framework Library, responsible for supporting images, supporting a variety of video and audio recording and playback; SQlite database, a powerful lightweight embedded relational database ; WebKit browser engine, etc.
Dalvik virtual machines:
different from Java virtual machines, each Android application executes in its own process, Have a Dalvik virtual machine of their own, which enables the system to be optimized at execution time, and the impact of the program is greatly reduced. The Dalvik virtual machine does not execute Java bytecode, but rather executes its own byte code. |
3. Application Framework (Application framework)
A rich and extensible view (views) that can be used to build applications that contain lists (lists), grids (grids), TextBox (text boxes), buttons (buttons), and embeddable Web browsers. Content Providers enables applications to access data from an application, such as a contact database, or to share their own data. The Resource Manager (Resource Manager) provides access to non-code resources such as local strings, graphics, and layout files (layoutfiles). The Notification Manager (Notification Manager) enables applications to display their own defined prompts in the status bar. The activity manager is used to manage the application lifecycle and provide the navigation fallback functionality that is often used.
2. Middleware middleware consists of two parts:
The Android system will include some app packages including email client,sms SMS program, calendar, map, browser, contact management program, etc. All the basic applications are now written in the Java language. |
