I have experience with Windows, the MacOS, the iPad and Linux UI's like KDE. I have not used an Android device however so I do not really understand how it works and compares. My general understanding is that it is similar to Gnome-like Linux interfaces, but I guess there must be some differences since Android has a layer of Java, the Dalvik/ART virtual machine, between the Linux kernel and the UI elements.
I have read the Android developer overview to the UI but that has not really helped me understand how the UI operates from a workflow basis.
Obviously I could just buy an Android tablet and use it for a few months, but I am hoping there is some way for me to understand the Android UI and how it differs from other major UIs. How can I get this knowledge?
