How to setup IAB in 2019?

Apollo14 · November 2019

Hi guys!

I've never tried to setup in-app purchases for GooglePlay.
Some questions raised:
1) Why I can't add events PRODUCT_COMPLETE & PRODUCT_ERROR? (are they deprecated from old googlebilling plugin?)
2) What does 'Iab:confirm()' do? I totally don't get what is that.
3) Is that code enough to integrate in-app purchase in my release version?
Or something essential is missing?

if application:getDeviceInfo() == "Android" then
	require "iab"
 
	IAB_GOOGLE=IAB.new("google")
	IAB_GOOGLE:setUp("VERY_LONG_API_KEY_FROM_GOOGLEPLAY_CONSOLE")
	IAB_GOOGLE:setProducts({remove_ads = "remove_ads"}) 
	IAB_GOOGLE:isAvailable()
 
	IAB_GOOGLE:addEventListener(Event.AVAILABLE, function(event)
		print("Event.AVAILABLE")
		IAB_GOOGLE:requestProducts()
	end)
 
--trying to add these two events result in lua error:
	IAB_GOOGLE:addEventListener(Event.PRODUCT_COMPLETE, function(event)
		print("Event.PRODUCT_COMPLETE:", event.productId, event.title, event.description, event.price)
	end)
	IAB_GOOGLE:addEventListener(Event.PRODUCT_ERROR, function(event)
		print("Event.PRODUCT_ERROR:", event.error)
	end)
--init.lua:213: bad argument #1 to 'addEventListener' (string expected, got nil)
--stack traceback:
--	init.lua:213: in main chunk
 
	IAB_GOOGLE:addEventListener(Event.PURCHASE_COMPLETE, function(event)
		print("Event.PURCHASE_COMPLETE", event.productId, event.receiptId)
 
		--User successfully purchased "no_ads", now I gotta reward him:
		SETTINGS.adsAllowed=false; SETTINGS.interstitialAllowed=false
 
		IAB_GOOGLE:confirm(event.productId) --what does it do?
	end)
	IAB_GOOGLE:addEventListener(Event.PURCHASE_ERROR, function(event)
		print("Event.PURCHASE_ERROR:", event.error)
	end)
end
 
--after "NoAds" button pushed, I'll have to call:
--IAB_GOOGLE:purchase("remove_ads")

Many thanks, guys!
P. S. btw how can we make test transanction without paying money to google?

This is my iab code from my game - it works fine for me.

if not tv then
	pcall(function() require "iab" end)
end
if IAB then
	if android then
		if kindle then
			iab=IAB.new("amazon")
			iab:setProducts({credit50="credit_50",credit100="credit_100",credit500="credit_500",credit1000="credit_1000"})
		else
			iab=IAB.new("google")
			iab:setUp(googleLicence)
			iab:setProducts({credit50="credit50",credit100="credit100",credit500="credit500",credit1000="credit1000"})
		end
	elseif ios then
		iab=IAB.new("ios")
		iab:setProducts({credit50="credit50",credit100="credit100",credit500="credit500",credit1000="credit1000"})
	end
 
	if iab then
		iab:setConsumables({"credit50","credit100","credit500","credit1000"})
		iab:addEventListener(Event.AVAILABLE,function(e)
			print("iab is available")
			iabCheck=false
			iab:requestProducts()
		end)
 
		--usually here we would set a flag that it is possible to make purchases
		--basically you can allow doing all the iap stuff after this event is called
 
		--[[ REQUESTING PRODUCTS ]]--
		--if this event is called, we received the list of products and information about them
		iab:addEventListener(Event.PRODUCTS_COMPLETE,function(e)
			print("Product list completed")
			for i = 1, #e.products do
				local p=e.products[i]
				--id, title, description and price
				print(p.productId,p.title,p.description,p.price)
				if p.productId=="fullgame" then
					iabCheck=true
					iabFullGame=false
				end
				for loop=1,#creditText do
					local c=creditText[loop]
					if p.productId==c[1] then
						c[2]=p.price
						c[3]=true
					end
				end
			end
			iab:restore()
		end)
 
		--else we could not retrieve information about products now
		iab:addEventListener(Event.PRODUCTS_ERROR,function(e)
			print(e:getType(),e.error)
		end)
 
		iab:addEventListener(Event.PURCHASE_COMPLETE,function(e)
			--purchases successfully completed 
			--here you need to check if receiptId was not already saved previously
			--as in if purchase was not already made
			--then you can unlock the item here
			--and store receiptId presistently to know 
			--that you have already provided this item to user
			print("Purchase completed")
			if remainingCredits<0 then remainingCredits=0 end
			if e.productId=="credit50" then
				remainingCredits+=50
				saveSettings()
			elseif e.productId=="credit100" then
				remainingCredits+=100
				saveSettings()
			elseif e.productId=="credit500" then
				remainingCredits+=500
				saveSettings()
			elseif e.productId=="credit1000" then
				remainingCredits+=1000
				saveSettings()
			elseif e.productId=="fullgame" then
				iabCheck=true
				iabFullGame=true
			end
			print(e:getType(),e.productId,e.receiptId)
		end)
 
		iab:addEventListener(Event.PURCHASE_ERROR,function(e)
			--it was not possible to complete the purchase, 
			--inform user
			--if e.error=="Unable to buy item (response: 7:Item Already Owned)" then
				iab:isAvailable()
			--end
	--		print(e:getType(),e.error)
		end)
 
		iab:addEventListener(Event.RESTORE_COMPLETE,function(e)
			--restore successfully completed 
			--here you need to check if receiptId was not already saved previously
			--as in if purchase was not already made
			--then you can unlock the item here
			--and store receiptId presistently to know 
			--that you have already provided this item to user
			if iabCheck then
				fullgame=iabFullGame
				saveSettings()
			end
			print("restore complete")
			--iab:purchase("credit500")
		end)
 
		iab:addEventListener(Event.RESTORE_ERROR,function(e)
			--it was not possible to complete the restore, 
			--inform user
		--	print(e:getType(),e.error)
 
		end)
		iab:isAvailable() 
	--		iab:purchase("credit100")
	else	
		print("iab provider not available")
	end
else
	print("iab not available")
end</pre>

To make a purchase I would:

if iab then	iab:purchase("credit50")

Okay I was slightly misguided by old Iab example from wiki. https://wiki.giderosmobile.com/index.php/Iab
@SinisterSoft I've replaced old example with your code

Thanks a lot, guys!

P. s. For some reason this stuff is not printed:<pre class="CodeBlock">

iab:addEventListener(Event.PRODUCTS_COMPLETE,function(e)
			print("Product list completed") --This line gets printed, but everything below does not (though I did setup products earlier:
--iab:setProducts({remove_ads="remove_ads"})
			for i = 1, #e.products do
				local p=e.products[i]
				--id, title, description and price
				print(p.productId,p.title,p.description,p.price)
				if p.productId=="fullgame" then
					iabCheck=true
					iabFullGame=false
				end
				for loop=1,#creditText do
					local c=creditText[loop]
					if p.productId==c[1] then
						c[2]=p.price
						c[3]=true
					end
				end
			end
			iab:restore()
		end)

@Apollo14 Glad to help. btw I can see that code in my browser. I'm using Brave browser (based on Chrome but better).
