It used to be an amazing experience, and when the news came out that Google was going to switch to IDEA for their official tools instead of going with that Eclipse I was thrilled. Finally everybody was going to able to know just how fast and efficient Android development can be.
How wrong I was. When Android Studio came out, it was incredible slow. Even today, after years of improvement to the developer experience it still isn't as efficient as plain IDEA was before Google created Android Studio.
I actually lay most of the blame on Gradle, which became mandatory around the same time. I never thought that someone would create a buid tool I dislike more than Maven, but it seems they succeeded.
