Answer 1

Always use "sp" for font and rest as "dp"

place your image in corresponding folder as below

suppose your are using 36x36 image in for mdpi you need to use

drawable-mdpi - 36 x 36
drawable-hdpi - 48 x 48
drawable-xhdpi  72 x 72

3:4:6:8 ratio

There are some situations in which you might not want Android to pre-scale a resource. The easiest way to avoid pre-scaling is to put the resource in a resource directory with the nodpi configuration qualifier.

For example:

res/drawable-nodpi/icon.png

for example

you are using an font size as 14sp means it will automatically change for 320 DPI as

14×320÷160 =28

so now your font size is 28dp for xhdpi resolution phone.
