Android Google Map Pins display with different sizes on different phones

Question

I am trying try implement display of pins on Android Google Maps.

I've successfully implemented it. However I'm abit confused as to why the pins are displayed in different sizes on different phones.

I am currently using the same R.drawable png file, which is stored under /res/drawable folder. Why is this happening? Is there a way to standardize this?

Below is a comparison for example, between a Samsung and HTC phone:

Answer 1

• small screen phones -> 36 x 36 px (ldpi)(120dpi)image size(keep under res/drawable-ldpi folder)
• normal screen phones-> 48 x 48 px (mdpi)(160dpi)image size(under res/drawable-mdpi)
• large screen phones/tablets-> 72 x 72 px (hdpi)(240dpi)image size(under res/drawable-hdpi)
• extra screen tablets-> 96 x 96 px (xhdpi)(320dpi)image size(under res/drawable-xhdpi)

if you have 4 PNG files with above mentioned size in appropriate folders, then it should look fine on all phones/tablets.
