Always set it to true... or better, just make android:targetSdkVersion =
4. Having it false is only for compatibility with old apps that were
written before there was a concept of density in the APIs. Using this
compatibility mode can cause some undesirable artifacts such as text metrics
being slightly inconsistent with actual rendering.

Hello there,
I've read

and
http://groups.google.com/group/android-developers/browse_thread/thread/ed305e5d08f11202/6b8feb7a05d9ef6b

and more related sources.
Still, what and when to set android:anyDensity to I find hard to
figure out.
So, are these conclusions correct:
1- android:anyDensity has been introduced really only for older apps
(1.6 level 4 or lower) because those were most likely built with
hardcoded density-dependent values like 'px'? And apps with level
before 4 even don't understand density dependent resource directories
like res/drawable-hdpi?
By setting android:anyDensity=false, Android tries to scale those
resources that use px values and in 'res/drawable' to match the
device's real screen density.
From level 5 onwards it is a well-known best-practice to always use dp
and sp and density dependend resource directories, so usually apps
take care themselves of being independent using those. And thus
normally for those apps android:anyDensity=true is sufficient (no
auto-density-scaling).
2- If android:anyDensity=false are these density dependend resource
directories plainly ignored as mentioned in this thread?
http://groups.google.com/group/android-developers/browse_frm/thread/518ee3894af29650
But: how does the android:anyDensity=true or false relate to
resources that you might have put in res/drawable-mdpi and res/
drawable-hdpi etc? Does that setting then only have effect for those
density resources you didn't specify in any configuration specific
density-directory, and how?
3- And what if I'm lazy and for any app I make I don't want to create
density specific resources (like images), so only have the 'res/
drawable' dir, but do use dp and sp everywhere... What should
android:anyDensity be set to then? My guess is false so Android will
alwyas scale my resources from 'drawable'...
Regards,
Marco
