If you recently started to develop applications for the Android platform (or any other mobile platform) it is likely that you will encounter the problem of designing user interfaces. Have you realized the importance of ListView control in developing android applications? That is what I learned the hard way. Don't allow this to happen to you too.

If you found that your R (resource) generated class in Android project have errors you will want to force Eclipse to rebuild that class. To force Eclipse to rebuild generated resource class (R), you just need to click on Project->Clean menu, and then select which projects you want to clean. 

In my case rebuilding generated class did not helped because there was error in my XML layout file and class again had the same error. So if you ever have error in your R (resource) generated class, it is better to first check your error log and find where in the layout or resource files you have error. Usual error is wrongly named resource id of control. After you fix that error and save changes error in R class will usually disappear.

Re: GIMP script for creating Android icons at once
Wow, thanks! I tried to hack your original script to add it in there but I don't know anything about script-fu and it ended up horribly.
Just a couple of notes: the ouya name and location matters so I changed it to:

(set! newName (string-append folder "/drawable-xhdpi/ouya_icon.png"))
(set! rawName "ouya_icon.png")
and this for banner (the name here is just a personal preference)
(set! newName (string-append folder "/drawable-xhdpi/banner.png"))
(set! rawName "banner.png")
Thanks again!
Re: GIMP script for creating Android icons at once
Dear Wildy,ouya and banner icons are completly different icons then standard android icons, and many of standard options don't apply to them, so I decided to write new script for you:

Installation procedure is the same as for the first script.
Re: GIMP script for creating Android icons at once
ouya_icon and banner both are 1.777777777777778 aspect ratio. I usually start with a 720p or 1080p bitmap maybe it would be possible to check for the correct aspect ratio before offering that option? Or before converting the bitmaps?
Thanks for the other fix though, it'll also save me a bit of manual renaming.
