(ioschedから抜粋)

public static boolean isHoneycomb() {
// Can use static final constants like HONEYCOMB, declared in later versions
// of the OS since they are inlined at compile time. This is guaranteed behavior.
return Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB;
}

public static boolean isTablet(Context context) {
return (context.getResources().getConfiguration().screenLayout
& Configuration.SCREENLAYOUT_SIZE_MASK)
>= Configuration.SCREENLAYOUT_SIZE_LARGE;
}

public static boolean isHoneycombTablet(Context context) {
return isHoneycomb() && isTablet(context);
