Thank you so much for the post!
Though, it has been explained earlier by many masters of this forum, but posting it again for the reference.
For those, who does not know the meaning/resolution of hdpi, xhdpi, etc. terms. Here is the explanation:
•A set of six generalized densities:
1] ldpi (low) ~120dpi
2] mdpi (medium) ~160dpi
3] hdpi (high) ~240dpi
4] xhdpi (extra-high) ~320dpi
5] xxhdpi (extra-extra-high) ~480dpi
6] xxxhdpi (extra-extra-extra-high) ~640dpi
So, chose wisely as per your device.
