Re: [android-developers] Re: When to set android:anyDensity to what value?
Our application is used when driving, and spends most of its life as a service, Not a single user has yet complained about grainy or jagged images, menu icons or some such in the UI part. The service occasionally shows custom toasts that cover the whole screen, and for these we use 300x300 pixel images . Looks perfect across all devices (although it has a bit of a performance hit on the older phones, but then again it is infrequent). YMMV -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: When to set android:anyDensity to what value?
That's exactly the point. Mobile utility applications have very short UI usage cycles. Users usually don't take the time to look for that jagged edge, they get the information they need and carry on. (Having said that I still get wound up each time I look at the built in Android web browser because I can't help noticing the horizontal misalignment between the address text field and the load progress bar... Pathetic, I know.) -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: When to set android:anyDensity to what value?
So I should set it to true even when my app doesn't include resources to accommodate any screen density (suppose I'm lazy so I don't create any size- or density specific resources)? I'm wondering this because taken from: http://developer.android.com/guide/topics/manifest/supports-screens-element.html it says that if you set anyDensity to true it means the application includes resources to accommodate any screen density. But I'm not including any of these explicitly, so what happens then scaling wise when anyDensity=true? On 5 apr, 23:09, Dianne Hackborn hack...@android.com wrote: 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.

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/5... 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'...

[android-developers] Re: When to set android:anyDensity to what value?
In short: am I always safe with anyDensity=true as long as I use dp and sp as I read in Table 2 here: http://developer.android.com/guide/practices/screens_support.html: 'That is, as long as your application uses density-independent units (dp) for screen layout sizes, then it will perform properly on different densities when this attribute is set to true'? Even for a 1.5 app? Or are there more rules like *having* to provide resources to accomodate any screen density (as it says here: http://developer.android.com/guide/topics/manifest/supports-screens-element.html: setting anyDensity to true means the application includes resources to accommodate any screen density?) -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: When to set android:anyDensity to what value?
There are really two related things here: 1 - Setting anyDensity to true or minSdk/targetSdk to 4 or above means that your application sees the real screen size/resolution/density at runtime. Android will scale your images as needed when they are loaded, so you won't get missing resource exceptions, but they may not always look very good, especially when scaling up, say from -mdpi to -hdpi density. You can look at Android's own resources as an example of this scheme: android-sdk-windows\platforms\android-X\data\res has drawable-mdpi and drawable-hdpi, but no drawable-ldpi, relying on runtime scaling from -mdpi to -ldpi. 2 - Using sp and dp units in your layouts makes them scale with density, so one layout should work for all densities (although you should still test them on a variety devices, because of different screen aspect ratios, this is especially apparent with QVGA screens). -- Kostya 10.04.2011 23:10, MarcoAndroid пишет: In short: am I always safe with anyDensity=true as long as I use dp and sp as I read in Table 2 here:http://developer.android.com/guide/practices/screens_support.html: 'That is, as long as your application uses density-independent units (dp) for screen layout sizes, then it will perform properly on different densities when this attribute is set to true'?

I have minSDK set to 3, anyDensity to true, and have just a single resource folder.

Re: [android-developers] Re: When to set android:anyDensity to what value?
Well you'll get 2x doubled images... but the screen itself is 2x the density of an mdpi screen, so the app's icons will mostly just look like they are on an mdpi screen. :} On Sun, Apr 10, 2011 at 5:49 PM, Zsolt Vasvari zvasv...@gmail.com wrote: Can't imagine that would look very good on an XHDPI screen.
