Does the Android SDK allow developers to leverage Swing or SWT for the GUI of apps? I'm assuming "no" for SWT since I do not believe there is an SWT port for Android, but Swing would still be interesting for a GUI.
It's neither, really. I haven't built anything on Android other than a lot of example code, but the UI is all custom, and centered around an API that makes it easy to write for the limited and varying screen space mobile devices provide. I found the XML GUI build system much easier to understand and work with than swing.
Thank you all for your responses. So, I can begin experimenting with the SDK since it provides its own GUI framework. And an added bonus of other GUI toolkits possible in the future certainly makes things interesting. It would just really be nice to leverage an existing codebase from the Java world for Android development.
