Searching the web and the Android Team announcement I couldn\'t find The answer. Will Eclipse ADT be deprecated when Android studio reach its first stable version? The funni
Personally I could not find the right answer about this. To be honest I feel very comfortable with eclipse and find it much more simple/clean/user-friendly that Android Studio or intellij. For me I will continue develop with Eclipse, is this a good decision?
Maybe you haven't used it that much. Let's be clear with this: IntelliJ is far better than Eclipse in almost any aspect. I also was an eclipse user for years, and I was in your position some time ago. But I must admit that IntelliJ simply works better. It's a better Java IDE, it has great support for things like Maven or Gradle, it's faster, it's smart (code completion, refactoring, etc.), it kind of understands you as a developer, it has also an Open Source version, and the list goes on and on.
So, the only reason not to switch, IMHO, is either laziness or fanaticism or you are color blind (this is the only reason I respect).
