    SIZE_HDPI="72x72"
    SIZE_XHDPI="96x96"
    SIZE_XXHDPI="144x144"

The error message means that the file c.png doesn't exist. I can reproduce your error message with a non-existent file:

$ convert nonexistent.png -resize 48x48 a/b/whatever.png
convert: unable to open image `nonexistent.png': No such file or directory @ error/blob.c/OpenBlob/2702.
convert: unable to open file `nonexistent.png' @ error/png.c/ReadPNGImage/3913.
convert: no images defined `a/b/whatever.png' @ error/convert.c/ConvertImageCommand/3241.

Probably you are in the wrong directory when you run the script. cd to the correct directory where the file exists, and also where the sub-directories mipmap-*dpi exist.

You can add a check before calling the resizing function like this:

if [ ! -f "$original" ]; then
    echo fatal: file does not exist: $original
    exit 1
fi
