Common In App Billing Interface

ar2rsawseen · October 2013

Updated IAB interface:

version 0.4
Added alpha code for IOS StoreKit

ar2rsawseen · October 2013

Specially for @moopf (inspired by his idea)

version 0.5
Added auto store detection with prioritization option

IAB.detectStores(priority1, priority2, ... priorityN) -- returns table with stores, that are available on device in provided priority order

example:

local stores = IAB.detectStores("google") -- will return table with google 
-- as first element if its available, 
-- and other supported stores, which are installed on device
 
local iab = IAB.new(stores[1])
 
--etc

So you can have single binary for all supported stores

@ar2rsawseen can you provide an example where we have 2 or 3 products with purchasing, please?
From setContent till purchase.complete.
And when you plan to finish with iOs in-apps?
Thanks.

ar2rsawseen · November 2013

Sure, this should cover all the available stores:

require "iab"
local iaps = IAB.detectStores()
iab = nil
if iaps[1] == "google" then
	iab = IAB.new(iaps[1])
	iab:setUp("google-key")
	--using google product identifiers
	iab:setProducts({p1 = "googleprod1", p2 = "googleprod2", p3 = "googleprod3"})
elseif iaps[1] == "amazon" then
	iab = IAB.new(iaps[1])
	--using amazon product identifiers
	iab:setProducts({p1 = "amazonprod1", p2 = "amazonprod2", p3 = "amazonprod3"})
elseif iaps[1] == "ios" then
	iab = IAB.new(iaps[1])
	--using ios product identifiers
	iab:setProducts({p1 = "iosprod1", p2 = "iosprod2", p3 = "iosprod3"})
end
 
--load previous purchases
purchases = dataSaver.loadValue("purchases")
--if there were no purchases
if not purchases then
	--create and store empty table
	purchases = {}
	dataSaver.saveValue("purchases", purchases)
end
 
--if we have a supported store
if iab then
	--set which products are consumables
	iab:setConsumables({"p1", "p2"})
 
	--if purchase complete
	iab:addEventListener(Event.PURCHASE_COMPLETE, function(e)
		--if it was not previousle purchases
		if not purchases[e.receiptId] then
			--save purchase
			purchases[e.receiptId] = true
			dataSaver.saveValue("purchases", purchases)
 
			if (e.productId == "p1") then
				--p1 was purchased
			elseif (e.productId == "p2") then
				--p2 was purchased
			elseif (e.productId == "p3") then
				--p3 was purchased
			end
			AlertDialog.new("Purchase Completed", "Purchase successfully completed", "Ok"):show()
		end
	end)
 
	--if there was an error
	iab:addEventListener(Event.PURCHASE_ERROR, function(e)
		AlertDialog.new("Purchase Canceled", e.error, "Ok"):show()
	end)
 
	--call restore on each app starts
	--or make a button to allow users to restore purchases
	iab:restore()
end
 
--some where in your code to make a purchase
stage:addEventListener(Event.MOUSE_UP, function()
	if iab then
		iab:purchase("p1")
	end
end)

Oh and about IOS, I tested it with test account and it seems to work great, now I submitted Mashballs with ios inapps using Common iab interface to see how it works in real life environment (and also to test that other rejection you mentioned in other thread) and now waiting for approval or rejection from them

unlying · November 2013

--using google product identifiers
iab:setProducts({googleprod1 = "p1", googleprod2 = "p2", googleprod3 = "p3"})

p1 - google product identifier

--set which products are consumables
iab:setConsumables({"p1", "p2"})

p1 - also google product identifier?

if (e.productId == "p1") then
--p1 was purchased

iab:purchase("p1")

- everytime google product identifier?

ar2rsawseen · November 2013

@unlying I see
in the table you pass to setProducts, key is the internal product identifier, while value is your in-app market specific product identifier.

for example, you can have a 100 coin in-app purchase, which in GooglePlay is called:
100ofCoins, in ios market its called com.yourdomain.yourapp.coins100, and in samsung market its called x0000000yvz.

Inside your app you just want to refer to it as coins100

Then for GooglePlay you provide:

iab:setProducts({oins100 = "100ofCoins"})

For IOS you provide:

iab:setProducts({coins100 = "com.yourdomain.yourapp.coins100"})

For samsung you provide:

iab:setProducts({coins100 = "x0000000yvz"})

And then in your app you use it as:

iab:purchase("coins100")

Hope that helps

unlying · November 2013

Khm. Gideros doesn't allow to use names like 100ofCoins. My google product has name 500coins. So i can't use this plugin for this product?

unlying · November 2013

And on app start i have this crash:
"11-13 23:10:57.785: E/IabHelper(18570): In-app billing error: Illegal state for operation (queryInventory): IAB helper is not set up"
Do i miss something?

ar2rsawseen · November 2013

@unlying ah sorry, lua stuff, you can write it as:

t = {}
t["100Coins"] = "some other value"
iab:setProducts(t)

and about error, it seems that you query products, before you set up the iab, like first you need to provide key, then set products, then set consumables and only then you can use the other iab functionality

unlying · November 2013

How is it possible? I'm using code that you provide without any changes except setting values for my project.

ar2rsawseen · November 2013

Ok let me check, also, there seem to be an upgrade for the lib, so let me also upgrade and retest

ar2rsawseen · November 2013

I've updated the lib and tested the code and can't reproduce the issue.

Please retry with updated lib (you can also try out the example project provided with the IAB plugin in the Labs)

But if issue still persists, might the reason be that you are using old version of Google Play?
In-app billing V3 needs 3.9.16 or higher (http://developer.android.com/google/play/billing/versions.html).

unlying · November 2013

No luck for me. Returned to standart...

ar2rsawseen · November 2013

Hmm, what Android OS version?

bml · December 2013

Support for receipt verification on a remote server would be much appreciated. Mainly exposing the required data and supporting the ability to manually finalize the purchase.

Thanks,
bml

ar2rsawseen · December 2013

Sure, will check which frameworks support remote server verification and will think on how to integrate it in the API

kredor7 · December 2013

Sure, this should cover all the available stores:

Thanks for this example helped a lot with initial setup on the in app billing process. I was having so many issues until I think it turned out to be Google's play store servers needed time to update. Was using the same code and getting issues until about 4-5hours in and everything was working smoothly.

SinisterSoft · February 2014

@ar2rsawseen On iOS when I add the iab folder to plugins then add it to the project, the app will crash - if I remove it it will work. Should I be removing some legacy storekit stuff if I use the iab plugin on ios?

ar2rsawseen · February 2014

Ok will check

SinisterSoft · March 2014

On Kindle (not tried proper Android) I have tried the Amazon store, the auto detect works fine, the available event fires but the iab:restore doesn't work - neither do any purchase requests (I get no events).

On Android the same program detects google play and all works great.

Any ideas?

Edit: Tried amazon on normal android and same result as Kindle.

Edit:

It looks like it's something to do with com.amazon.testclient.iap.purchase ???

03-07 22:27:50.280: W/ActivityManager(2356): Unable to start service Intent { act=com.amazon.testclient.iap.purchase flg=0x10000000 (has extras) } U=0: not found
03-07 22:27:53.035: W/ActivityManager(2356): Unable to start service Intent { act=com.amazon.testclient.iap.purchase flg=0x10000000 (has extras) } U=0: not found

SinisterSoft · March 2014

Ahhh.....

"Amazon differs from Google's PlayStore in that you cannot test purchases with Amazon's servers at all, until your app has been approved and published:

Only apps that have been approved and published through the Distribution Portal can communicate with the Amazon Client.
https://developer.amazon.com/sdk/in-app-purchasing/documentation/testing-iap.html

So until that point, your only option for debugging and testing purchases is to use the Amazon Tester app which emulates the Amazon store.

This line means the Amazon API is requesting Amazon's SDK tester App but it is not installed on your device:

11-26 11:16:29.033: W/ActivityManager(61): Unable to start service Intent{ act=com.amazon.testclient.iap.purchase flg=0x10000000 (has extras) }: not found"

ar2rsawseen · March 2014

@SinisterSoft yes, I have used that to test Amazon IAP interface, you simply install the tester app and prepare a json file with responses, that you put in the root of your Android.

But I also have a published app with iaps on amazon through same interface and they work great

zaniar · April 2014

I have played around with iab plugin and found this issue.

This code doesn't work on iOS:

iab:setProducts({p1 = "iosprod1", p2 = "iosprod2", p3 = "iosprod3"})

But, this one works:

iab:setProducts({"iosprod1" = p1, "iosprod2" = p2, "iosprod3" = p3})

I think this issue should be fixed for the sake of consistency. Isn't it? :-?

ar2rsawseen · April 2014

@zaniar ah I was catching a bug and could not understand what happens wrong, and that could make sense. I mixed up them.
Thank you so much

ar2rsawseen · April 2014

Hmm but again looking at the code I don't see anything reversed. Still thanks for the clue, now at least I have something to work with

zaniar · April 2014

I have got other issues on iOS.

* event.productId is reversed. The value is com.something.coin1000 instead of coin1000. I believe this issue is related to previous issue I reported.

* requestProduct called automatically. Is this the correct behaviour? Android doesn't behave this way though.

I hope the update will come soon 8->

I have workaround for the productId issue but not for the requestProduct issue.

lsouchet · April 2014

Hello,
I also have issues with iOS.

* When I do a setProducts it calls requestProducts and does not retrieve any remote product.
* The product Id also seem inverted when I debug the plugin in XCode.
* When I requestProducts() and use the xCode debugger, I see that the request is sent, no product is received and then the app displays a popup requiring to log in. When I log in with my test user account no new event is raised and still no products are received.

I used basically the example provided by @ar2rsawseen, my app is on iTunes connect in "waiting for upload" status and the in app products are "waiting for review".
Did I make something wrong?
Could somebody make IAB interface working on iOS?

Thanks

ar2rsawseen · April 2014

Will work on it today

ar2rsawseen · April 2014

Updated IAB interface:

version 0.6
Added initial version of Nokia Store
Fixed IOS internal key and store key mix
Fixed IOS requesting products upon setting
