Android is a complete mobile platform which contains an operating System, Middle ware and a powerfully API. But the most interesting thing is that, the total mobile platform is Open Source and purely based on free and open source software. Google has released a SDK for Android application development and for easy use, there is an Android plugin for eclipse which is already done by Google.
