Hi,

I can tell you that the R class only contains the predefined strings , layouts, drawables etc.
For example (string): Every string name you see in the string.xml will get an id in pointed automatically in the R class.
For example (drawable): An image thats held in the drawable folder will get an id pointed automatically in the R class.

What value(s) are you holding in that String Array ? Is it an URI and where do you get it from?

Yours sincerely,
Mike Jesmiatka

Hi,

I do not know for sure what you mean, but you should not edit the R class yourself. It will be generated.
If you want to use a drawable just place it in that directory and you will be able to call it's ID by using:
R.drawable.<name>

Again, I'm not sure what your intention or problem is so sorry if I give you useless information.

Hi,

just use windows for copying and pasting it in your project directory.
The directory to place it in is the following:
%project%/res/drawable/


Just paste the needed file there, be sure to refresh your project. The R file will now update himself and you will be able to call the image with. R.drawable.<name>

You can also paste the file in eclipse, same directory

Note:
You don't need the .jpg for calling the file. For example:
image.jpg will be called with R.drawable.image
