Full parsing of the Android operating system

Andrew Koenig also wrote a modern Android operating system tutorial "Accelerated C ++". However, has the Android operating system improved over the years? Is the Android operating system really unstable.

I have been idle for some time recently. I can study the development of new mobile phone operating system applications. The next generation of mobile phone built-in functions will no longer be the deciding factor. How to allow a third party to quickly develop applications on mobile phones will be the battle heights of the military.

I am a Windows Mobile programmer and have been working for a long time. Why choose Android in the new Mobile operating system? Because Android and Windows Mobile are so similar, why?

1. Operating System and mobile phone hardware separation modes. The most interesting thing is that the hardware supplier is actually one;

2. You can use managed code for Development (. net cf and Java)

3. Free sdks

4. IDE integrated development environment Visual Studio and Eclipse)

5. powerful Server software supports Windows Server, SQL Server, Exchange, and Google Online Service. Therefore, in terms of technology, Windows Mobile and Android are different implementations of the same technology, it embodies the idea of taking software and online services as the core, and is different from the mobile phone-centric idea of iPhone and Symbian.

It's hard to say who is right or wrong. However, there is another important reason why I don't select the iPhone: I don't have a Mac computer, so I cannot build a development environment. If the iPhone is defeated in the future, this will be a very fatal mistake.

Now, let's first introduce the development environment. my operating system is Windows Vista, and I didn't install Visual Studio development tools, which is not my usual working machine ). The first step is to access the Android homepage, which is easily accessible through Google. It must be admitted that the Android operating system documentation has greatly improved compared to the one I visited half a year ago. You can easily find a guide on how to install the development environment. This is very useful for non-Java developers.

The software I installed includes:

These software links are available on the Android operating system homepage. I first installed JDK 6, decompressed Eclipse 3.4, and did not need to be installed. Next, Android SDK 1.0 does not need to be installed. First, we need to set the Android SDK to the environment variable. The Android SDK directory contains the docs, samples, and tools directories, and we need to set the tools directory to the Path variable in the environment variable.
