Welcome to the Treehouse Community
Looking to learn something new?
You're bad explain...
i don't understand half of your explanation... Or maybe this course is not for beginners.
Have some patience... there are many things nobody understands the first time... but after a lot of practice it will start making sense.
You need to understand a little bit of JAVA to learn android. I would suggest to start going through Java courses and finish the track. Once you understand OOP, you will understand android development.
