Hi guys I need a little help, please. In the tutorial for creating a simple android app I'm trying to set up the emulator for my Fun Facts project. In the SDK manager I need to install the system image and SDK platform, but when I try to install it I get this message: 'Done. Nothing was installed.' I can see there's been a similar question from someone else before, but it seems it hasn't been answered yet. Grateful if you could let me know where I'm going wrong. Thanks, Ben

Initially I couldn't understand what you meant, because the word "image" made me wonder what it looks like, but after googling it out I saw that, system images are packages you install through the SDK manager. That helped me understand what you are saying. Thanks :)

If you can't find a better way, in Windows, in SDK/tools folder find Android.bat file and run it, also as administrator. I think it's a safest way to start SDK Manager with permissions and everything else needed set.

I am having the same issue but on a Mac. Does any one know how to correct this? Since I do not have windows I am not sure if the answer above applies to me?
Thanks in advance!

13,104 PointsThe answer applies to you but with MAC it is more complex than windows. Try to read How to Run GUI Apps as root in Mac OS X, for that.

13,104 PointsWhat do you mean by system image? Also what is your operating system?
