The project is divided into three steps:
1, save acquired from the official website of the epidemic latest data to the database.
2, web server deployed to end.
3, Android end request to the server database data acquisition and display.
data collection:
I use pycharm compiled crawler, get data from Lilac Park epidemic official website and saved to the server database; taking into account the relatively small server, so once every 24 hours crawling.
web-side deployment:
When you click to confirm, on the left there will be Chinese epidemic distribution right will be distributed in the form of foreign epidemic. 
Android end of the show:
HttpUrlConnection request with the deployed Web Servlet project data, to show resolve in the local WebView after obtaining Json string; drawback is a bit slow.
Summary: The first relatively complete a complete project, while the use python, android, web and other languages, but also first learned request data HttpUrlConnection, feeling suddenly open a lot of eyes (although unable to speak ...).
