Android is based on linux, so it is best under ubuntu. Of course, it is also possible under windows. But the kernel of android is based on linux, and it is very powerful and more convenient than cmd.

The general development environment is as follows: ubuntu system, formerly windows, and then install ubuntu virtual machine. The development of android is mostly application development from the middle layer to the top layer, so it is basically java development.

The table is as follows: 1eclipse is an essential tool for developing java and android. (Of course, the premise is to install JDK 1.6 first.)

Download SDK and ADT for android. This is an essential tool for developing android, adb, ddms, mksdcard, aapt and debug.

A After installing eclipse, install ADT through help to install new software.

B then window=preference sets the path of SDK.

If developed in C, you can install CDT.

Now you can install the api on the platform you want through AVD manager, such as android2.3.4, and you can build a 2.3.4 simulator to run the simulator. It is researched and developed through tools such as ddms of ADB. For convenience, add the path of adb to the environment variable.

What can Android mobile phone software development do? What can Android mobile phone software development do? Seek an answer

One of the advantages of Android mobile phone system lies in its openness and free service. Android is a completely open third-party software platform, and developers have more freedom when developing programs for it, breaking through the constraint that only a few fixed software such as iPhone can be added. At the same time, unlike Windows Mobile, Symbian and other vendors, the Android operating system is provided to developers for free, which can save nearly 30% of the cost. The Android project has received strong support from mobile phone operators, mobile phone manufacturers, developers and consumers. Open handset alliance members listed below can show their great strength: open handset alliance members: 1. Mobile phone manufacturers: 1, Nokia 2, Samsung 3, Motorola 4, HTC 5, Sony Ericsson 6, RIM 7, LG 8, Blackberry 9, Apple 10, ZTE 2, semiconductor companies: Semiconductor: 1, SMIC 2, TSMC 3, Dalian Intel 4, Suzhou Hejian 5. 0. Ningbo BYD III. Software Company 1, Huawei Technologies Zhejiang University Network New Technology Co., Ltd. 6. Panda Electronics Group Co., Ltd. 7. Beijing Peking University Founder Group Co., Ltd. 8. Tongfang Co., Ltd. 9. Alcatel Shanghai Bell Co., Ltd. 10, and Inspur Group Co., Ltd. Android also received a lot of developer support. According to Google, within two months after its launch, programmers have downloaded this software development platform more than 250,000 times. Although only a small number of developers actually started to write actual applications in such a huge download volume, we can see amazing developer interest from it. In contrast, one year after the launch of Symbian operating system, its operation guide was downloaded only about 70,000 times. Zhou Yongming, CEO of HTC, said that the shipment of T-MobileG 1 mobile phones based on Google's Android platform is expected to reach 1 10,000 units by the end of this year, compared with the previous forecast of 600,000 units. It seems that "Google mobile phone" is selling well and its prospects are optimistic, although it is low-key publicity. Android is in China. You should understand that as an initial member of open handset alliance, China Mobile began to recruit and develop its own Android phones as early as last year. In addition, various cottage manufacturers are also vigorously transplanting Android, and the so-called Kiki i6, the first Android phone in China, has been exposed.

How to learn Android and develop Android mobile phone software

Android applications present users with the most interfaces, so whether the interface is beautiful or not is an important factor for users to choose to use. It is very important for engineers to improve their own aesthetics and then integrate their understanding of beauty into their applications. If you are interested in Android hair, you can come to Wuhan Siwei DreamWorks to find out.

Is there no foundation to learn android mobile phone software development?

If you don't have a foundation, you have to get started. Programming can't be finished quickly. You have to start with java applets, including installing jdk and jre. You can learn the basics of Java from scratch and gradually advance to development projects. The quickest way is to participate in android development training, which can be zero-based and trained for four months.

Who can talk about the development of Android mobile phone software?

China Boda 3G College has a good response, and the teachers there all have development experience in this field.

Have a real online application, and then pay after employment.

How to recruit a group of Android mobile phone software developers?

Personal understanding is that for an enterprise that needs to make its own Android client, profit is not necessary ~ for example, Kingdee's Notes, its greater role is to improve brand awareness and cultivate user habits.

It's as if adobe is deliberately not doing so well in anti-piracy in order to cultivate user habits and brand awareness.

I have been reading. Do you know how to ask questions in the forum?

What should be paid attention to when developing mobile phone software to meet functional requirements? How about Tian Ruidi 'an mobile phone software development?

Generally, we should pay attention to the level and ability of development, whether there are successful cases, how to deal with bugs found in the later stage of the developed APP, how to upgrade the version and so on. If you need to develop a mobile app, you can @ me.

Is there a training place for Android mobile phone software development in Jinhua?

"Tell you a true story. An accident missed the best opportunity for fresh graduates to find jobs. Because we have been expecting to engage in the embedded industry, and the starting point of banks is relatively high, companies generally do not recruit fresh graduates, but only professionals with work experience or basic technicians with training experience. So I took a year off after the operation and chose Power Node or Wang Yong java. During these four months' study, I not only consolidated the language foundation of software development, but also made up for the lack of exam-oriented education in college classroom. Because during the training period, although video teaching is often used, the learning mode of tapping code while listening to the class not only deepens the classroom understanding, but also strengthens the ability of hands-on and brain. Here, I would like to express my sincere thanks to all the teachers and classmates who have helped me in Power Node or Wang Yong java! Y

Is mobile phone software development difficult to learn?

Mobile phone software development is highly technical. Only by receiving a good education and having a good learning attitude will it be difficult.

What do you mainly learn in Android software development? In the past six months, Android software development, mobile phone Android system and ios system are the mainstream mobile phone systems. What is the main purpose of Android software development? IT training found that there are many technologies developed by Android, and it is unrealistic to learn them well at one time, but the following foundations should be learned well.

1, activity life cycle

Although Android has four components, it is undeniable that Activity is the most commonly used. Therefore, it is necessary to master the life cycle of Android. In fact, the life cycle is to remember when those active methods are called by the system, so that the corresponding logic code can be written into the appropriate methods.

As for the service and broadcast components, we can slow down a little and study them when they are actually used.

2. Interface development technology

Interface development is a basic technology, which is needed by almost all programs. There are three kinds of interface development in Android development:

1) uses xml file layout.

It is the most common application software development technology to use xml to lay out interfaces first and then refer to them in activities. This method is used the most and needs to be learned the most. You need to be familiar with:

A) Five layouts

A deep understanding of the five organization modes of controls is a basic foundation, so that you can flexibly use each layout structure in the actual interface and construct the required interface.

B) public control

There are many controls, at least you need to know what each control does, and you can look up specific parameters and methods when you need to learn.

C) interface beautification

In many cases, the control of the system can not meet the requirements, and it needs to be beautified by adding background and changing pictures. You should be familiar with how to beautify each control.

Mastering the above contents of android software development, you can make various interfaces through nested layout. If you are familiar with the use of include, you can reduce the repetition of xml and facilitate the later modification and maintenance of android software development.

2) Dynamic creation using code

Sometimes you need to create some layouts and controls dynamically, so you need to use LayoutInflater to create some dynamic interfaces.

3) Draw your own interface

Commonly used in the game, inherit SurfaceView and draw it yourself.

3. Data storage technology

There are three ways to store data in Android:

1) shared preferred storage

Simple data can be stored in this way, and some basic data can be stored in the form of key-value pairs.

2) File storage

Store data in the form of a file, which can be the storage of the mobile phone itself or the SD card. The data format of the file is defined by itself.

3)SQLite database storage

Operating with standard SQL statements is the first choice for complex data.

4, network programming

There are not many Android programs that don't need to be connected to the internet now. So network programming is also necessary. General companies will have their own network architecture, but they should be familiar with the basic network.

1)HTTP networking

Using Http networking +Json data format is the first choice for many clients now.

2) Socket network

As for the connection methods such as Bluetooth, you can learn when the project needs it.

For the system functions of mobile phones, such as making phone calls, sending text messages, reading system parameters, etc. You can study on demand without any trouble.

Secondly, mobile phone software is related.

Android development is different from ordinary computer software development, and it needs to know the operating habits of mobile phones, such as small screen, limited memory and limited battery. Therefore, it should be considered as much as possible in the actual development and design.

Java Training of Beida Jade Bird: What is the development prospect of Android software? What is the development prospect of Android software? In today's society where intelligent hardware is rampant, various black technologies emerge in an endless stream, Android systems are constantly updated and iterated, mobile phone production is increasing, and users are also growing.

What is the development prospect of Android software? Now Android is developing very well. Whether it's post-80s or post-90s, there is more and more love for Android phones.

It has also driven a lot of employment in the Android industry. Why does Android have such great magic? The reason is his source code development. Google has been innovating and updating its products for a long time to stay alive. According to the previous data, Android has shown a strong advantage. In two years, it surpassed Saipan at that time and became the most popular system, occupying most of the mobile phone market.

Android system is widely used, not only on mobile phones, but also on tablet computers.

And now domestic mobile phones all use Android system, such as Huawei, ZTE, Xiaomi and so on. , accelerating the development of Android system, making its users more and more, and the technical personnel about Android are also needed by enterprises.

What is the development prospect of Android software? The general training institutions in the market only train one of them, and the knowledge of the professors is very narrow.

Some only teach you one-sided knowledge, which cannot be widely used in companies and enterprises. They can only go to the company for a lot of secondary study, and their wages are rising again and again. Our country is really short of talents in this field.

Computer training found that in order to develop this industry more quickly, both schools and society need to contribute their own strength.

What language is used for Android software development? Android uses Java as the programming language.

The communication bridge between operating system and application is divided into two layers: functional layer and virtual machine. Bionic is an improved version of libc for Android.

Android also includes Webkit, the engine behind Apple's Safari browser. Surface flinger displays 2D or 3D content on the screen. Android uses Google's self-made bionic Libc tool chain.

Android is based on OpenCORE, open core. OpenCORE can be divided into seven modules: PVPlayer, PVAuthor, Codec, Packet Video Multimedia Framework (PVMF), Operating System Compatibility Library (oscl), Common and OpenMAX.
