                "Density: " + String.valueOf(dm.density) + "\n" +
                "DensityDPI: " + String.valueOf(dm.densityDpi) + "\n" +
                "Scaled Density: " + String.valueOf(dm.scaledDensity) + "\n" +
                "X DPI: " + String.valueOf(dm.xdpi) + "\n" +
                "Y DPI: " + String.valueOf(dm.ydpi) + "\n");
