There is no way. You can set a boolean inside res/values

<bool name="isHandest">false</bool>

inside values-sw600dp, values-sw720dp and values-xlarge

and

<bool name="isHandest">true</bool>

in res/values

what about tablet 7 inch running 3.0 OS, this will not work – Mahmoud Jorban Jun 02 '13 at 14:53
It should be on values-large. Imho a 7" with android lower.than 3.2 it is not a tablet – Blackbelt Jun 02 '13 at 15:41

Use the Smallest-width Qualifier:

The Smallest-width qualifier allows you to target screens that have a certain minimum width given in dp. For example, the typical 7" tablet has a minimum width of 600 dp, so if you want your UI to have two panes on those screens (but a single list on smaller screens), you can use the same two layouts from the previous section for single and two-pane layouts, but instead of the large size qualifier, use sw600dp to indicate the two-pane layout is for screens on which the smallest-width is 600 dp

You can use different layouts or set a boolean in these folders:

<resources>
    <bool name="is_tablet">true</bool>
</resources>

From official doc: http://developer.android.com/training/multiscreen/screensizes.html

but if the OS is less than 3.2 its useless – Mahmoud Jorban Jun 02 '13 at 14:52 — Mahmoud Jorban, Jun 02 '13 at 14:52

If you define tablet as device with screen bigger than 7"

public static boolean isTablet() {
    return screenSize >= 7;
}

public static double getScreenSize(Activity activity){
    DisplayMetrics dm = new DisplayMetrics();
    activity.getWindowManager().getDefaultDisplay().getMetrics(dm);
    double x = Math.pow(dm.widthPixels/dm.xdpi,2);
    double y = Math.pow(dm.heightPixels/dm.ydpi,2);
    screenSize = Math.sqrt(x+y);        
    return screenSize;
}

I believe "smallest width" resources qualifier like sw600dp does not work for Android version below 3.2? I cannot use layout-large as devices with screen size 5.4, 5.8, 6.3 fall into that category as well (while the first Samsung Galaxy Tab thinks it has normal layout). This is the problem I face in my project, beside calculating the screen size, no other way works for me. – Ethan Jun 02 '13 at 13:27
