I did build my android game on version Android 5.0 'Lollipop' (API level 21) but plenty of devices is not supported after upload what is the best build version that support most devices
If you target API 17, you should get a good spread of devices. You will have to test though, looking at performance impact and requirements of your game.
You may even be able to lower the API level to 14, but then though the game can install on a device, there may be many devices it doesn't work on.
Just a note, Android works on providing a minimum and target API Level. It is recommended to have the target API level be newest (or as new I guess), so you can have that set to 21, but minimum to 14 or 17.

I hope that helps...
