How to get the screen density programmatically in android?

I mean: How to find the screen dpi of the current device?

Answer 1

If you want to retrieve the density from a Service it works like this:

WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
DisplayMetrics metrics = new DisplayMetrics();
wm.getDefaultDisplay().getMetrics(metrics);
