I am about to start developing an android app and need to get an IDE. Eclipse and the android eclipse plugin appears to be the natural choice. However I am familiar with intelliJ and re-sharper so I would prefer use intelliJ.
Has anyone used https://code.google.com/archive/p/idea-android/? Is this any good?
Should I just bite the bullet and learn Eclipse?
Android Studio has officially come out of beta and been released. It is now the official IDE for Android Development - Eclipse won't be supported anymore. It is definitely the IDE of choice for Android Development. Link to download page: http://developer.android.com/sdk/index.html
As of Google I/O 2013, the Android team has moved to IntelliJ Idea with the new Android Studio IDE: http://developer.android.com/sdk/installing/studio.html
Great to see Google endorse Idea. It is safe to say that Android Studio, and thus Idea, will from now on be the definitive IDE for Android development! :D
If you are used to IntelliJ, I don't think it would be beneficial to switch IDEs just for Android tools. You can work on Android with any text editor (I use Vim). If you're more productive with a specific environment I don't see why you'd have to learn a new one. Not worth it in my opinion. Plus I'm a big IntelliJ fan. The IntelliJ plugin lets you make apk files and push the app to the emulator, that's all you need for Android app development. I'd say you're safe sticking with IntelliJ.
Update: there is now an official free IDE for IntelliJ android dev! http://blogs.jetbrains.com/idea/2010/10/intellij-idea-10-free-ide-for-android-development/
Eclipse is not that hard to learn (I use both Eclipse and NetBeans, and I switch back and forth pretty effortlessly). If you're going to be learning Android development from the start, I can recommend Hello, Android, which I just finished. It shows you exactly how to use all the features of Eclipse that are useful for developing Android apps. There's also a brief section on getting set up to develop from the command line and from other IDEs.
