Answer 1

I made a project with a drawable that is only in the "res/drawable" folder, tested it on my One X, and confirmed the image is displayed:

Layout:

Resources:

res/drawable/drawableonly.png  
res/drawable-hdpi  
res/drawable-hdpi/ic_launcher.png  
res/drawable-ldpi  
res/drawable-mdpi  
res/drawable-mdpi/ic_launcher.png

res/values/strings.xml  
res/values/styles.xml  
res/values-v11

res/values-v14  
res/values-v14/styles.xml  

You can try to figure out what you are doing different that might be triggering some other behavior. Keep in mind that having a "drawable" folder and a "drawable-mdpi" folder is a little odd, because the drawable folder is mdpi density by default. It may be not be deterministic which of those two will get used. I know using a density specifier does automatically append a -v4 in modern build tools to fix problems with Android 1.5 not understanding these specifiers and handling them correctly, so drawable-mdpi-v4 might be considered to have more specifiers and match in precedence compare to drawable. Both folders have a mdpi density class anyway, however, so keep in mind your drawable from either folder will be scaled up automatically if used from there.
