title: How to set an imageView's image from a string?
body: <p>I have a list of entries and some bitmap files in the res/drawable-mdpi directory. I'm trying to load the image corresponding to the string value selected from the list by generating a path string and using bitmap factory. The problem is I don't think my path is right because the bitmap is always null, even for the default image.</p>
  
  <pre><code>String name = entries.get(position);
              String img = "res/drawable/logo_" + name.toLowerCase() + ".png"; // create the file name
              icon.setScaleType(ImageView.ScaleType.CENTER_CROP);
  
              // check to see if the file exists
              File file = new File(img);
              if (file.exists()){
  
                  bm = BitmapFactory.decodeFile(img);
              }
              else{// use the default icon
                  bm = BitmapFactory.decodeFile("logo_default.png");
              }
  
              // set the image and text
              icon.setImageBitmap(bm);
  </code></pre>
  
  <p>Does the res directory even get copied onto the device? What is the correct path I should be using, or should I be going about this differently?</p>
  
  <p>Thanks</p>
