android imageView doesn't like my .png file

Question

I am trying to load a .png file for for things in my app that do not have images.

I have my noImage.png in the res>drawable directory and try and set it with:

//set image
        ImageView im1 = (ImageView) findViewById(R.id.image);
        if(e.largeLabel.equals("N/A")){
            //set image as png
            im1.setImageResource(R.drawable.noImage.png);
        }

        else{
            ImageDownloadTask imageD = new ImageDownloadTask(im1);
            imageD.execute(e.largeLabel);
        }

I get the error:

png cannot be resolved or is not a field

Update:

Based on some answers below I changed my code to this:

im1.setImageResource((Integer) R.drawable.noImage);

But I get this force close error:

I get an error otherwise: The method setImageResource(int) in the type ImageView is not applicable for the arguments (Object) — Mike, Jun 25 '13 at 01:09
wooooow. wait what? Object? what the hell have you done with the R file? R.drawable.(...) should return an integer. I think you have messed the imports. — Diogo Bento, Jun 25 '13 at 01:17
@DiogoBento where can I find it so I can try and fix it? Eclipse suggested an edit to it earlier when I was trying to get my png to work... — Mike, Jun 25 '13 at 01:20
look at the imports, the R file should be a reference to a class **inside** your project. not the android one neither anything else. You dont have to create an R file because it is generated automatically. — Diogo Bento, Jun 25 '13 at 01:23
and btw, I truly recommend you to read some book about android.. — Diogo Bento, Jun 25 '13 at 01:26
I know eclipse edited the r file when I said yes to one of its suggestions, how can I undo it? — Mike, Jun 25 '13 at 01:27

In Netbeans all I need to do is "clean and build" to regenerate the R file, I believe there is something similar in Eclipse, and you should really never manually modify R file — Chor Wai Chun, Jun 25 '13 at 02:00

My problem was the name of my image. I can not have uppercase letters in the res folder. I had to change the name from noImage.png to noimage.png and everyone was correct in that I do not use the .png when calling it in android.

this should be the accepted answer, we cannot have any unique character for the resource naming, allowed: `lowercase & underscore` cmiiw – mochadwi Feb 03 '20 at 01:15

You don't specify the file extension when accessing resources. Use R.drawable.noImage instead.
