getting the screen density programmatically in android?

Question

How to get the screen density programmatically in android?

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

Answer 1

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

switch(metrics.densityDpi) {
     case DisplayMetrics.DENSITY_LOW:
         break;

     case DisplayMetrics.DENSITY_MEDIUM:
         break;

     case DisplayMetrics.DENSITY_HIGH:
         break;
}

This will work on API level 4 and higher.
