What are the response codes (values) returned by the Google Play server in a license response?

Question

I want to cater for LICENSE_OLD_KEY in my android license policy. I was going to modify the ServerManagedPolicy as it doesn't cater for this, as far as I can tell, it just seems to look for Policy.LICENSED or Policy.NOT_LICENSED in processServerResponse method:

public void processServerResponse(int response, ResponseData rawData) {

    // Update retry counter
    if (response != Policy.RETRY) {
        setRetryCount(0);
    } else {
        setRetryCount(mRetryCount + 1);
    }

    if (response == Policy.LICENSED) {
        // Update server policy data
        Map<String, String> extras = decodeExtras(rawData.extra);
        mLastResponse = response;
        setValidityTimestamp(extras.get("VT"));
        setRetryUntil(extras.get("GT"));
        setMaxRetries(extras.get("GR"));
    } else if (response == Policy.NOT_LICENSED) {
        // Clear out stale policy data
        setValidityTimestamp(DEFAULT_VALIDITY_TIMESTAMP);
        setRetryUntil(DEFAULT_RETRY_UNTIL);
        setMaxRetries(DEFAULT_MAX_RETRIES);
    }

    setLastResponse(response);
    mPreferences.commit();
}

I'd like to know what the response code is for LICENSE_OLD_KEY because that doesn't exist in Policy:

public static final int LICENSED = 0x0100;
public static final int NOT_LICENSED = 0x0231;
public static final int RETRY = 0x0123;

I had a look here, but I can't find anywhere that lists the name and values.

I can see that there are a list of server response codes in LicenseValidator but they don't match up to those in Policy:

    // Server response codes.
private static final int LICENSED = 0x0;
private static final int NOT_LICENSED = 0x1;
private static final int LICENSED_OLD_KEY = 0x2;
private static final int ERROR_NOT_MARKET_MANAGED = 0x3;
private static final int ERROR_SERVER_FAILURE = 0x4;
private static final int ERROR_OVER_QUOTA = 0x5;

private static final int ERROR_CONTACTING_SERVER = 0x101;
private static final int ERROR_INVALID_PACKAGE_NAME = 0x102;
private static final int ERROR_NON_MATCHING_UID = 0x103;

Answer 1

Giving it some thought I decided to try displaying the reason codes returned by the Google Play server on my phone, using AlertDialog's. Here is what I found:

Selecting LICENSED, in the Developer console profile, returned the number 256, as per Policy.LICENSED.

Selecting NOT_LICENSED returned the number 561, again as per Policy.NOT_LICENSED.

Finally selecting LICENSED_OLD_KEY returned the number 256, which is the same as Policy.LICENSED.

So it would seem that LICENSED_OLD_KEY is no longer used, or rather there is no distinction between LICENSED and LICENSED_OLD_KEY. Which is a bit confusing given the information that google provide in their documentation here.

Just to note, I did try uninstalling my app and selecting the different options in the developer console a few times, but it always resulted in the same answer!
