Getting started with Android development for Windows (1)

Seeing extensive publicity on csdn and the Internet, I decided to get involved in the Android mobile development field based on my existing Java experience. I found the relevant learning materials one morning, later, I downloaded the Android app development secrets ebook on the Internet, which has been uploaded to my resources. If you are interested, you can download the ebook.

Because Google has recently closed Open Source Access to android3, the android open website cannot be used, and Android JDK and ADT cannot be downloaded from the official website, you can search for and download it from a dog. Of course, because it is based on Java, We need to download JDK or later and eclipse3 or later. The specific address is not mentioned, because I use eclipse, so I didn't download it. You searched a lot on the Internet.

If you have any problems, you can use Baidu to provide graphic configuration tutorials.
