[Android Study Notes] 01-build and familiarize yourself with the android Development Environment

On the morning of October 1st, I introduced various smartphone operating systems, including Android, IOS, and windowns phone. Then I started my experiment in the afternoon.

Android development environment. The steps are not complex. It took a whole afternoon, mainly because the network speed of the data center was too slow, and the installation process could not avoid access to the Internet.
