Subject:Re: [android-developers] Changing the "scaled pixel" size

This is for a global system setting, which is not currently available to users. If you want to have a local font scale setting in your app, you will need to implement that yourself.

In a number of places the documentation recommends specifying font sizes in "sp" (scaled pixels) because the size can then be adjusted by "user preference". However, AFAIK there is no global way to do this. So if I want to allow users to increase or decrease the font size in my app, I assume that I'll have to implement my own app-specific preference.

The problem is that I can't see how to change the setting. DisplayMetrics has a "scaledDensity" field that is obviously the scaling factor that affects font specified in "sp", but I don't see any way to change that value. Am I missing something?
