If you need the actual lcd pixel density you can get it from the metrics.xdpi and metrics.ydpi properties for horizontal and vertical density respectively. — Giridharan, Feb 06 '15 at 07:14

You could also try accessing through the Display class.

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);

String strOpt = "PIXEL：" + size.x + " × " + size.y;
