Unity Android IAP "Purchase failed because Purchasing was not initialized correctly"

What I have
IAP button is working perfectly in unity editor. After purchasing, i'm getting debug message "ProcessPurchase: PASS. Product: 'full_version'" . But the button does nothing when I try to make a purchase on the device.
Don't have any errors when purchasing product in editor
What have i done so far
Automatically initialize UnityPurchasing checkbox is switched ON screenshot from unity IAP catalog
I've checked that the product ID, and price are the same in unity and Play console
My IAP product is showing active in play console IAP in play console
setup the Codeless IAP like this
Unity IAP button component
LogCat error when I press the button on the device

You are mixing Codeless and Scripted IAP unfortunately. You should avoid Codeless IAP altogether, it has not been updated in some time and has issues, as you are seeing. Instead, use Scripted IAP (only). Read: this forum

Error You Already Own This Item

I have a new android app in which I am adding in-app billing and I am tearing my hair out with frustration.
I have uploaded a signed APK and published to alpha. I created a set of in-app products and activated them all. I have created a new gmail account and defined them as a tester for the app on the app apk page.
I have factory reset my android phone and initialised it with the new gmail account. I have entered the /apps/testing link in to chrome and signed up as a tester. I then downloaded and installed my app. Inside my app I asked for the in app products that were available and was shown the set i created above. I selected one to buy and went through the following purchase process.
1. Screen shows product to be purchased and price and requests press continue which i do
2. Screen shows payment methods and I select redeem code
3. Screen shows redeem your code and I enter one of the promotion codes I set up in the developer console earlier (not mentioned above - sorry) and press redeem
4. Screen shows product again, this time with price crossed out and offers option to add item which I select (very strange being asked to add again buy hey ho)
5. Screen shows item added
6. After a fews seconds screen shows Error you already own this item.
How can this be, this user did not exist before ten minutes ago and has only used this app once as described above.
I have seen many questions in stack overflow and elsewhere similar to this and tried everything, clearing google play store cache, clearing google play store data etc. This sequence described above is my latest attempt with a completely clean user on a completely clean phone.
I could upload my app code used but that misses the point, which is how can this gmail account already own an item when this gmail account have never purchased anything before from anyone. Surely this is a bug.
All clues very welcome as to how to proceed. Code now added, note this is a hybrid android app, with the user purchase decisions code in javascript/html and the in app actions in the wrapper code below

String command = commandJSON.getString("method");

};

I have found that this error does not occur when using paypal (i.e. real money) to make the purchase, so I believe that this "Error you already own this item" message is in some way connected to using a promotion code for the test. And (so far) my paypal account has not been charged (as I am a resgistered tester for the app).

How to debug in-app billing on Android 4.1 and 4.2?

New to Android dev and I have this very annoying, and familiar problem.
Short version: how can I test my app on multiple physical devices w/o buying them? Specifically, I'm trying to test on 4.1 and 4.2 running devices. I can't use an emulator because this involves in-app billing.
Long version:
Today, I got a crash report from a user (android version = 4.2, on device = A1-811 (mango)).
The issue is: IAB helper is not set up. Can't perform operation: queryInventory . I tested the app on 4.3, 5.0, 5.1 and it's fine.
I KNOW that the actual crash happened because I wasn't quitting when I was checking for (!result.isSuccess()) in mhelper.startSetup().
My question is, how do I solve the underlying issue of IabHelper not being set up?! I don't have access to Android 4.2 device...
MY CODE:
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener () {
public void onIabPurchaseFinished (IabResult result, Purchase purchase) {
if (mHelper == null)
return;
if (result.isFailure ()) {
Log.d (PURCHASE_TAG, "Google's response is a failure.");
} else {
Log.d (PURCHASE_TAG, "Response is successful. purchase.getSKU = " + purchase.getSku ());
premium = true;
}
}
};
IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener () {
public void onQueryInventoryFinished (IabResult result, Inventory inventory) {
Log.d (PURCHASE_TAG, "Processing Google's response.");
// Check if user has existing purchase.
if (result.isFailure ()) {
Log.d (PURCHASE_TAG, "Google's response is a failure. Response = ");
} else {
Log.d (PURCHASE_TAG, "Google's response is success! getPurchase() = " + inventory.getPurchase (THE_SKU));
if (inventory.getPurchase (THE_SKU) == null) {
premium = false;
} else {
premium = inventory.getPurchase (THE_SKU).getSku ().equals (THE_SKU);
}
}
// Show price if user is not premium, thank you note if the user is premium
if (premium == true) {
Log.d (PURCHASE_TAG, "3 premium = " + premium);
priceView.setText ("Thank you for the purchase!");
} else {
if (inventory != null) {
String pro_price = inventory.getSkuDetails (THE_SKU).getPrice ();
priceView.setText ("" + pro_price);
}
}
}
};
private void startPurchaseQuery () {
String base64EncodedPublicKey = "the key is generated ...";
mHelper = new IabHelper (this, base64EncodedPublicKey);
Log.d (PURCHASE_TAG, "Purchase query started.");
mHelper.startSetup (new IabHelper.OnIabSetupFinishedListener () {
public void onIabSetupFinished (IabResult result) {
Log.d (PURCHASE_TAG, "IabHelper Setup successful. Querying inventory.");
if (!result.isSuccess ()) {
Log.d (PURCHASE_TAG, "Error with IabHelper setup.");
return;
}
if (mHelper == null) return;
// IAB is fully set up. Now, let's get an inventory of stuff we own.
// Build the SKU list
List<String> additionalSkuList;
additionalSkuList = new ArrayList<String> ();
additionalSkuList.add (THE_SKU);
// Make the query
mHelper.queryInventoryAsync (true, additionalSkuList, mQueryFinishedListener);
Log.d (PURCHASE_TAG, "Query finished. Premium status = " + premium);
}
});
}
#Override
protected void onActivityResult (int requestCode, int resultCode, Intent data) {
Log.d (PURCHASE_TAG, "onActivityResult(" + requestCode + "," + resultCode + "," + data);
// Pass on the activity result to the helper for handling
if (!mHelper.handleActivityResult (requestCode, resultCode, data)) {
// not handled, so handle it ourselves (here's where you'd
// perform any handling of activity results not related to in-app
// billing...
super.onActivityResult (requestCode, resultCode, data);
} else {
Log.d (PURCHASE_TAG, "onActivityResult handled by IABUtil.");
}
}
#Override
public void onDestroy () {
super.onDestroy ();
if (mHelper != null) mHelper.dispose ();
mHelper = null;
}

Answer from comments above
It's better to catch the error and patch own code first. Trying to reproduce exact issue why was IAB not set up may not be possible, because of all kinds of modifications user can do on his device (could be bug with specific version of distro user is running, which is almost impossible to find out, or similar). As you suggested, using Analytics to find out how many users have this issue is good approach.
To answer original question, you can create Alpha or Beta versions in Developer Console and invite users with specific versions of Android you'd like to target into testing group. This was you could test issues and crashes directly from Dev. Console even when not directly being owner of the device.

InAppBilling v3 IabResult response code BILLING_RESPONSE_RESULT_ITEM_ALREADY_OWNED

Following the docs on developer site , i have implemented InAppBilling v3 in my app recently . I have used the classes in the utils package provided in the TRIVIAL DRIVE sample.
The problem i am facing is if a user has purchased an in app product already on launching purchse flow again on another device the play store dialog shows ITEM ALREADY OWNED but the response code returned by IabResult does not match to the constant IabHelper.BILLING_RESPONSE_RESULT_ITEM_ALREADY_OWNED . The response code returned is actually one of the error codes in IabHelper class (-1005 User cancelled).
I would really like to know how can i get the actual response code instead of error code. Any help would be appreciated.
Below is the code for callback
// Callback for when a purchase is finished
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener =
new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
if (result.isFailure()) {
if (result.getResponse() ==
IabHelper.BILLING_RESPONSE_RESULT_ITEM_ALREADY_OWNED) {
//already owned
boolean isPremium = true;
SharedPrefsUtils.setPremium(BaseActivity.this, isPremium);
EventBus.getDefault().post(new InAppBillingUiUpdateEvent(isPremium));
//setWaitScreen(false);
return;
}
//handle error
complain(result.getResponse() + " " + "Error purchasing: " + result);
//setWaitScreen(false);
return;
}
if (!verifyDeveloperPayload(purchase)) {
//corrupted
complain("Error purchasing. Authenticity verification failed.");
//setWaitScreen(false);
return;
}
//successful
if (purchase.getSku().equals(NO_ADS_PRODUCT_ID)) {
// bought the premium upgrade!
alert("Thank you for upgrading to premium!");
boolean isPremium = true;
SharedPrefsUtils.setPremium(BaseActivity.this, isPremium);
EventBus.getDefault().post(new InAppBillingUiUpdateEvent(isPremium));
//setWaitScreen(false);
}
}
};

I finally managed to find the problem in the IabHelper code , So here it goes whenever an Activity.RESULT_CANCELED result code is returned in handleActivityResult method the IabResult for all such cases is fixed with user cancelled (-1005) no matter what the reason is. So in order to get the correct actual response code replace the following code in handleActivityResult
else if (resultCode == Activity.RESULT_CANCELED) {
logDebug("Purchase canceled - Response: " + getResponseDesc(responseCode));
result = new IabResult(IABHELPER_USER_CANCELLED, "User canceled.");
if (mPurchaseListener != null) mPurchaseListener.onIabPurchaseFinished(result, null);
}
with this
else if (resultCode == Activity.RESULT_CANCELED) {
logDebug("Purchase canceled - Response: " + getResponseDesc(responseCode));
result = new IabResult(responseCode, null);
if (mPurchaseListener != null) mPurchaseListener.onIabPurchaseFinished(result, null);
}
hope it will saves someones time

My products are Managed products in developer account In-app Products
EDIT:
When I use android.test.purchased as a SKU then it works fine and as I change my sku with my product_id then it giving me Error Authentication is required. You need to sign into your Google Account.

Please make sure your product id on playstore for in app purchase which is "test_product" you should use the same sku in your code. And if you change the sku from your application, then all that possible sku names must exists on PlayStore as in-app Products. I once run into this problem and the reason was my SKU item was not exists on Google Playstore in-app products i just add it on Playstore and it was resolved.

Android IAB Error - Authentication required
It seems that you need to publish the APK. I stuck with this problem too.

It is a bit of a longshot, but your "Google Play store" app could be malfunctioning.
I have a report from a customer that he cannot make an In-App purchase and he is getting this same error. I also know that we are still getting purchases. So I don't think you necessarily configured anything wrong. IAB v3 could simply be malfunctioning with your "Google Play Store" app.
Try going to Settings open the Application manager and choose the "Google Play store" application in the list, and click on "Uninstall updates" button which appears there. Next try to do the purchase again. If your old Google Play application supports In-App billing v3 it will work. If it doesn't, try to update the "Google Play store" app again, perhaps you will get a newer/different version of the store app and you will be able to make the purchase.
As an alternative you can try and configure a second test device with a different Google account... or ask a friend to join a beta test group and make a test purchase.
I am not really happy with IAB v3. It feels a little clunky. V2 had fewer features but felt solid.
