Use, DisplayMetrics to get screen info from your device.

Some sample code,

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);

final int height = dm.heightPixels;
final int width = dm.widthPixels;

EDIT:

float xDpi =   dm.xdpi;
float yDpi =   dm.ydpi;

float density = dm.density;
