Android development exercise assignment: paper, gold, and silver real-time price query app

From: http://www.techolics.com/android/software/20121204_322.html

I recently learned how to develop the Android mobile phone system, so I want to find some practical examples to learn and practice. I just found that there was an app on the iPhone that could query paper gold and silver prices in real time. It should be a very small tool. It should not be difficult to make it, so I decided to use it for practical practice, write a Real-Time paper, gold, and silver price query software similar to Android. So the application of the first Android platform was born :)
