Welcome to the Treehouse Community
Looking to learn something new?
Could i use NeatBeans?
for my IDE?
You can make Android Apps with alsmost any Java IDE these days. Maybe you might want to use this plugin: http://plugins.netbeans.org/plugin/19545/nbandroid
I would still highly recommend Android Studio 2 since most Tutorials (not only Treehouse) out there are created with it.
Also all parts of the Android "Getting Started" are created in Android Studiohttps://developer.android.com/training/index.html
by the way. Android Studio is build on the Intellij IDEA from Jetbrains...a widely used Java IDE that is pretty common today.
