How to create basic Android app?

At last,I learn how to create a simple Android application..3 days I sit in front of my laptop,searching in Google for tutorial's and understand the tutorial I found.Out of all tutorials in Internet only 2 tutorials I managed to understand.So,I try n error to building an app by applying what i learned from these two tutorials.Not perfect but close enough.Before I show you the website of the tutorial,here is the screenshot of the app I made.(Not for showing off,but to show that anyone can do it.it is simple!)click the image to view clearly.
