Please help for starting and is it possible to greate android services?

Hi,
I want to start programing for android via Qt. Please help me first to know every thing that I need to download and install on my Windows8.1(32 bit) and also please give me some document for study. And please tell me that can android services be created by Qt for android? My friend told me it is imposible to create services (running backround) for android by Qt.
