Cannot understand Android WebView documentation

Question

I find it's hard to follow Android WebView documentation. For example, what is the difference between setMinimumLogicalFontSize and setMinimumFontSize?

According to documentation:

setMinimumLogicalFontSize: Sets the minimum logical font size. The default is 8.

setMinimumFontSize: Sets the minimum font size. The default is 8.

Basically, it tells nothing, and I have no idea what is font size and what is logical font size.

Can anyone explain the meaning?

Answer 1

I found the explanation not for android, but for iOS. I think it's the same thing:

The minimum logical font size is the smallest font size that will display in a web view when the content’s font size is imprecisely specified. This includes content with logical sizes (such as small) or with a font size specified as a percentage of the default.

and

minimumFontSize

This sets the minimum display font size for the web view, overriding all content-specified styles, including explicitly specified font sizes.
