Screen size, in terms of small/normal/large/xlarge, will be determined by device manufacturers based upon physical screen size and the distance that screen will be from the user. A phone is held closer to the user's eyes than is a tablet, and both are held closer to the user's eyes than is an LCD TV. At best, Google might come up with a size guideline per form factor -- 10 tablets are xlarge, for example. However, in the end, the device manufacturer will choose the value for the device. How the device manufacturer makes that choice, AFAIK, is up to the device manufacturer. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to *Advanced* Android Development_ Version 1.9 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: How to detect tablet devices
Is there any numeric size about XLARGE screens? AFAIK there could be
smartphone devices with xlarge screens, or not? I don't see any
documentation which says that XLARGE screens are 6 inches
Does xlarge refer to the phisical size? or resolution?

No no no no no.
getResources().getConfiguration() tells you this kind of stuff about the
device.
Look for LARGE or XLARGE screen size, depending on what you want to do.
And of course you can have your resources adjust automatically by using
things like layout-xlarge.

Here is the code I use for my app:

try {
// Compute screen size
DisplayMetrics dm =
context.getResources().getDisplayMetrics();
float screenWidth = dm.widthPixels / dm.xdpi;
float screenHeight = dm.heightPixels / dm.ydpi;
double size = Math.sqrt(Math.pow(screenWidth, 2) +
Math.pow(screenHeight, 2));
// Tablet devices should have a screen size greater than 6

Re: [android-developers] Re: How to detect tablet devices
Dianne, I'm confused.
If your response had six no's, I'd know not to do this for sureĊ but with
just five ?
This appears to be a grey issueĊ :)

Re: [android-developers] Re: How to detect tablet devices
In fact, you really shouldn't think target a tablet. What does tablet mean? You will quickly find that this is an incredibly nebulous term. Target screen size: adjust your UI for xlarge (or large). Target other specific hardware aspects that make sense for you (does it have a hardware keyboard? Phone radio? Etc).
