Android studio made easy work for us to make android app in no time. It have many features like syntax highlight, Code completion and so much more. It comes with it sown emulator in which you can debug you app without actual device
It very slow during startup and compilation time. But There is no option other then using Android studio.It occupies more memory.
I advise students and working guys to shift to Android studio for app development It makes you work way more easy compared to traditional way.
I have learned making android application using android studio . after that i have developed sample demo apps. I have worked on Big Android project in my company
