Android Studio is only in beta, but it’s awesome! It is a huge improvement from the Eclipse development environment. It is my first experience with the IntelliJ IDE so I had to learn all new shortcuts. The wysiwyg works great and they system warns you of Android API compatibility issues in your code and layouts. The main problem I have ran into with the beta version is the new gradle build system. If you start with a fresh install of Android Studio, there probably isn’t any problems, but when upgrading to newer beta releases, they project builds change and that can cause problems with existing projects. Gradle also gives very cryptic error messages which can leave you scratching your head. Overall though, Android Studio has been a good experience and has motivated me in building 3 apps that have been published so far. I will post about each one and some code snippets from them.
