How to get the screen density programmatically in android?

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

Answer 1

The following answer is a small improvement based upon qwertzguy's answer.

double density = getResources().getDisplayMetrics().density;
if (density >= 4.0) {
   //"xxxhdpi";
}
else if (density >= 3.0 && density < 4.0) {
   //xxhdpi
}
else if (density >= 2.0) {
   //xhdpi
}
else if (density >= 1.5 && density < 2.0) {
   //hdpi
}
else if (density >= 1.0 && density < 1.5) {
   //mdpi
}
