Question

I have an application developed for Honeycomb (initially 3.0) and after the ICS is released the users can install it to theirs phones with ICS, not just to tablets. How can I filter these phones? I have tried with the <support-screens> but that is not working. Also an interesting (at least to me) thing my application won’t scale down to smaller screens. I used fixed sized controls but the size is in dp.

In short:

1. Somebody knows how can I filter the ICS phones? (preferably from code)
2. What should I do to support ICS phones? (I guess I need to implement a whole new layout for the ICS phones, but it is still a question to me how can I determine what kind of device is it, phone or tablet?

Answer 1

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);
}

You will also probably want to restrict Android Market from enabling users to install this on phones with http://developer.android.com/guide/topics/manifest/supports-screens-element.html in your manifest.
