I primarily program in Python and have always tried to steer clear of Java (no particular reason, really). Now I find myself in a position where I have to build an app for Android.
My question is, is there any inherent difference in terms of speed, resource-consumption, access to hardware features etc if I build the app in Python, using SL4A or Kivy or some other platform(I still need to explore those options in detail)? Or should I Download the SDK Bundle and go about learning to build apps for Android exclusively?
