    How I do IAP?

    I should have asked this BEFORE starting with Gideros... But now the app is almost done anyway...

    So, how I do IAP? What I want to do is that you download the full app, and use IAP to unlock the demo version to full version (our game is a story-based game, you will see roughly 2/7 of the story, and then must pay to see the remaing 5/7)

      Well from logical point of view, most probably you will have a file saved in the |D| folder which stores values, including if the game is unlocked or not.
      Upon app start you load values and check if game is unlocked
      Upon IAP purchase you store value true to unlock the game there
      Additionally you may choose to encrypt this file (there are plenty of lua based encryption libs/modules, most probably some members can suggest something).

      But if you mean from implementation point of view, then go to Gideros Labs and download IAB interface:
      http://giderosmobile.com/labs/iab

      It provides store detection and same interface and workflow for different stores.
      The docs and state of stores can be seen here:
      http://docs.giderosmobile.com/interface/iab

      And here is a draft code to support GooglePlay, Amazon and IOS
      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 iab is available/loaded
	iab:addEventListener(Event.AVAILABLE, function(e)
		iab.loaded = true
		--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)
	iab:isAvailable()
end
 
--some where in your code to make a purchase
stage:addEventListener(Event.MOUSE_UP, function()
	if iab and iab.loaded then
		iab:purchase("p1")
	end
end)

      Hi @ar2rsawseen

      I'm trying to get IAB working but I have one issue that I'm not sure how to resolve.

      I have followed the installation instructions (on Github) and I've also double checked all the lib and src files. The APK compiles without any errors but when I install it on a device it crashes. The reason for the crash is on:
      require "iab"
      It must be something very simple. Maybe something is not being exported or referenced correctly.

      I also noticed that the instructions specifically for Google billing are as follows:

      Google

      src\com\android\vending\billing folder
      src\com\giderosmobile\android\plugins\iab\google folder
      src\com\giderosmobile\android\plugins\iab\IabGoogle.java

      However, the files are located in the frameworks folder. Is this correct?

      Should it be?:

      Google

      src\com\android\vending\billing folder
      src\com\giderosmobile\android\plugins\iab\frameworks\google folder
      src\com\giderosmobile\android\plugins\iab\frameworks\IabGoogle.java

      Many thanks in advance.

      PS. I will be testing Fortumo in the future so I will be more than happy to tell you about my experience.

      From further research it looks as if there is a file dependency/linking issue. Can someone help me find the file(s) that are missing? I removed Google billing v2, so I ave may have removed files that are still required. Please help me!

      Have you copied libiap.so file into libs/arm and libs/armv7 folders?

      Have you loaded iap library from main Activity: System.loadLibrary("iap")?

      @jdbc I followed all the instructions several times but I couldn't get it to work, so I decided to start over.

      I created a new export from Gideros and after I added the IAB plugin. This resolved my issue. I must have messed up the previous project some how. At the moment I only have the IAB plugin but I need to add flurry and ads plugin to completely test everything.

      Apple has changed the way to define product ID.

      Now prefix with app bundle id is not needed, you only have to provide the product ID as Google does. You can test the list of products in your device emulator from Xcode.
