If Google's (NASDAQ:GOOGL) I/O conference isn't enough to draw more developers to its services, the company's Android Studio -- a free integrated development environment that makes Android programming easier -- may do the trick.

Android Studio comes with features such as an advanced code editor, a "smoother and richer" graphical user interface, and greater customization for complex configurations.

Google has also made it easier to add other Google services through Android Studios. For example, developers can now add Google Cloud Messaging or a translation plug-in to help localize their apps' language.

Android Studios is currently in the hands of testers and early adopters. For all other developers, Google will continue to support Eclipse as its primary platform for development.
