I want to learn

[arima0k]

There are many sites on the internet to learn, I am using codecademy, but i would like a recommendation of the experts about methods, pages, or other thread where you have dealt with this topic or similar.
I'll not ask again, I am self-taught and excuse my English.
Thank you.

Welcome to XDA! For app development I would recommend checking out Google's official tutorial on building your first app https://developer.android.com/training/basics/firstapp/index.html. Google also has a free Udacity course for learning Android app development which can be found here https://www.udacity.com/courses/android. As far as ROM development I would suggest taking a look at Google's building Android from source guide here https://source.android.com/source/initializing.html. Let me know if you have any other questions !
