I finally got some time to set up one of my machines for the Android development environment, and I'm a bit confused. When I started reading up a few weeks ago, I was under the impression that I could use OpenJDK as the Java component, but, when I got to the installation requirements I see this:
Supported Development Environments
Eclipse 3.4 (Ganymede) or greater
Eclipse JDT plugin (included in most Eclipse IDE packages)
If you need to install or update Eclipse, you can download it from http://www.eclipse.org/downloads/.
Several types of Eclipse packages are available for each platform. For developing Android applications, we recommend that you install one of these packages:
Eclipse IDE for Java Developers
Eclipse Classic (versions 3.5.1 and higher)
Eclipse IDE for Java EE Developers
JDK 5 or JDK 6 (JRE alone is not sufficient)
Android Development Tools plugin (recommended)
Not compatible with Gnu Compiler for Java (gcj)
The last 3 lines seem to me to say that one needs Oracle/Sun Java JDK. Can anyone confirm this for me? I was hoping to stay Open Source.
