1) First, download the android SDK. Introduce a very simple method to download eclipse together. Enter android SDK in Baidu to enter the search interface. Check the first item.

After entering the download interface, select the SDK suitable for your computer to download. What I downloaded here is an android development tool, which is very simple and practical. We don't need to download eclipse again. In this download package, we will bring an eclipse FOR android development tool in which we can develop android directly.

Decompress after downloading. After decompression, we enter the folder named eclipse. Click the eclipse application and run it. Running as shown in the figure is different from eclipse, because it is an android development tool, which is only suitable for developing android. There are good plug-ins that have been provided to us, and there is no need to install them.

After entering the eclipse interface, start creating new android projects. Enter a name for the new project. If there are no special requirements, please click Next until you are finished. The initial configuration is just a general framework structure, which we can modify later. The most important thing is to write code.
