OPENIAB in-app purchases

jdbc · March 2014

Hi all again.

I am asking what about a plugin for http://www.onepf.org/openiab. This is a project that enables to use several in-app with same API.

I know Gideros Labs http://giderosmobile.com/labs/iab provides for OUYA, Google Billing and Amazon, but this provides more app stores with same API.

ar2rsawseen · March 2014

oh but there is one

But OPENIAB provides a java wrapped API for Yandex, Samsung and T-Store. Less effort to Lua - java plugin.

And what about "OpenIAB Lib detects which appstore installed the app."

ar2rsawseen · March 2014

But ours supports also IOS (under the same API and workflow) and additionally OUYA, and also detects available stores.
Here is the full code working crossplatform with every supported store:

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)

What IAB Interface provides:
Same API through all supported In-app billing frameworks on all platforms
Completely same workflow for all In-app Billing frameworks
Can dynamically detect which stores are installed on device and return the list to you in prioritized order, so you can have one single binary for all stores
Provides internal product ID usage through all In-app Billing frameworks, which might use different product IDs
Provides unique Receipt ID even if In-app Billing does not support it
Manages all the confirmation and consumption internally

Yes it might need some more work and polishing and testing now, but the end result will be better and easier to add new additional stores

jdbc · March 2014

Cool

It was one idea for reduce development effort on Gideros Labs IAP plugin :-)

I suppose we can use

iab:setProducts({p1 = "prod1", p2 = "prod2", p3 = "prod3"})

with the same product Ids for all stores:

ar2rsawseen · March 2014

yes, that was the idea, since ios and Google have different formats for product Ids you can set up and use same ids internally and let plugin handle store specific ids

SinisterSoft · March 2014

I added IAB with the lib from labs - I removed the gideros google billing stuff first.

But when I try iab:restore() I get a crash with this in the eclipse log:

03-01 21:46:41.755: D/HeyzapSDK(30234): Tracking heyzap-start event.

IabHelper is in the set of files included in the src folder, etc...

Any ideas?

SinisterSoft · March 2014

Ahh - figured it out:

--if there was an error
iab:addEventListener(Event.PURCHASE_ERROR, function(e)
AlertDialog.new("Purchase Cancelled",e.error,"Ok"):show()
end)

iab:addEventListener(Event.RESTORE_COMPLETE, function(e)
AlertDialog.new("restore iab","","Ok"):show()
end)

iab:addEventListener(Event.AVAILABLE, function(e)
iab:restore()
end)

iab:isAvailable()
--call restore on each app starts
--or make a button to allow users to restore purchases
--iab:restore()
end

If you just do an iab:restore() then it will fail (and fail with a crash!)- you have to see if it's available and do the restore in that event. You instructions don't mention that you should check availablity first.

ar2rsawseen · March 2014

Hmm, true will implement also internal check

hgvyas123 · March 2015

Hi

google has stopped support for version 2 and forcing us to use version 3 now so instead of googlebilling plugin i am using iab plugin now but have some problem in it just my understanding is not clear so please help me with below points

how can i buy android.test.purchased multiple time as i am intending this to test to purchase coins? it was working fine i can purchase multiple time with android.test.purchased with version 2 but with version 3 it can be purchased only one time

also is it like managed product will purchased only on 1 time and un managed product can be purchased any number of time means i dont have to do anything in code

hgvyas123 · March 2015

ok now as per google doc it says,

Unmanaged products behave differently if you are using in-app billing v3 rather than in-app billing v2. If you are using in-app billing v3, Unmanaged products are treated as Managed products and will need to be explicitly consumed. Learn more

so how can i consume item or plugin is doing this for me automatically

ar2rsawseen · March 2015

you need to use setConsumables method
http://docs.giderosmobile.com/interface/iab

to specify that this item is consumable

Thanks bro it worked

Hi again in this thread.

I was trying to use in-app purchases with SlideMe appstore, so I was studying again OpenIab:
https://github.com/onepf/OpenIAB

I have created a new class IapOpen implementing IabInterface and it seems it works also for Google Play, and I have add a new method startSetup Iad and IabInterface to call mHelper.startSetup().

I also was trying to use the strategy searching:

 
OpenIabHelper.Options.Builder builder = new OpenIabHelper.Options.Builder();
builder.addStoreKey(OpenIabHelper.NAME_SLIDEME, key)			.setStoreSearchStrategy(OpenIabHelper.Options.SEARCH_STRATEGY_INSTALLER_THEN_BEST_FIT)
.setVerifyMode(OpenIabHelper.Options.VERIFY_SKIP);

In the lua part I use:

iab = IAB.new("open")
iab:setUp(slideme_key)

I suppose there is one way to specify IAB.new("open", "slideme")...

Wow impressive, care to submit PR in Github?

jdbc · June 2015

For Google Play app store, it works using the following java code in the IapOpen class and init method:

<a href="https://forum.giderosmobile.com/profile/Override" rel="nofollow">@Override</a>
	public void init(Object parameters) {
 
		SparseArray<byte[]> p = (SparseArray<byte[]>)parameters;
		try {
			String key = new String(p.get(0), "UTF-8");
			OpenIabHelper.Options.Builder builder = new OpenIabHelper.Options.Builder();
			builder.addStoreKey(OpenIabHelper.NAME_GOOGLE, key)
					.setStoreSearchStrategy(OpenIabHelper.Options.SEARCH_STRATEGY_INSTALLER_THEN_BEST_FIT)
					.setVerifyMode(OpenIabHelper.Options.VERIFY_SKIP);
					//.setVerifyMode(OpenIabHelper.Options.VERIFY_EVERYTHING);
			mHelper = new OpenIabHelper(sActivity.get(), builder.build());
 
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		}
 
	}

In the lua part

iab = IAB.new("open")
iab:setUp(googleplay_key)

I suppose the only difference with the rest of app stores (Amazon, Yandex, AppMall, SlideMe, Aptoide,...) is this init method and productId list. But Google Play and SlideMe productId list is the same. :-)

So the only difference is the app public key :

builder.addStoreKey(OpenIabHelper.NAME_GOOGLE, key)

Wow impressive, care to submit PR in Github?

I will when I finish my OpenIAB integration, the Android project with java code and jar files will be submitted to Github, may be to allow integration with current Gideros IAB plugin.

I have discovered we must to use the following command to allow app store SlideMe discovery using OpenIAB java classes.

adb install -i com.slideme.sam.manager /path/to/YourApp.apk

¿How does Gideros Iab plugin detect the stores?

ar2rsawseen · June 2015

Yes basically app must be installed by slideme store to be detected

Gideros provides a method in each Iab[Store] class to detect if this store is available
like:

https://github.com/gideros/gideros/blob/master/plugins/iab/source/Android/src/com/giderosmobile/android/plugins/iab/frameworks/IabGoogle.java#L30

like:

https://github.com/gideros/gideros/blob/master/plugins/iab/source/Android/src/com/giderosmobile/android/plugins/iab/frameworks/IabGoogle.java#L30

After a little investigating OpenIab API I know how to detect app stores:

OpenIab calls to OpenIapHelper.startSetup method depending on the OpenIapHelper.Options object. This Options object contains all app stores keys and app lookup strategy (installer or billing provider), so my IabOpen could be the same for all Open app stores (SlideMe, Yandex, AppMall, Aptoide) if I could provide a list of app stores key from lua and the product id will be the same as Google Play.

ar2rsawseen · June 2015

@jdbc thats great

iab:setup method supports passing multiple arguments

as you call

iab:setup(value1, value2, value3)

which will get SparseArray on Android side with all values in same sequence

so you can also provide all needed keys that way

About look up strategy, then IAB, uses something similar, when you call

IAB.detectStores(priority1, priority2, ... priorityN)

you provide a priority list of stores to detect, so it returns the table of supported stores in this priority order, skipping the ones it does not support.

Maybe it can be used in OpenIab case too

jdbc · June 2015

@ar2rsawseen I know IAB plugin provides a look up strategy, but I do not know if it is better than detect stores will be transparent for user.

I mean, from Lua it was easier to do something as:

  local iap = IAB.new("open")
  iap.setup({"googleplay" = googleplay_key, "slideme" = slideme_key, "yandex", yandex_key, "appmall", appmall_key}
  iap.setPreferred("slideme")

in one step and later java code detects stores to avoid if .. then lua code.

ar2rsawseen · June 2015

well if then is needed either way, because device might not support any of the stores at all.

jdbc · June 2015

well if then is needed either way, because device might not support any of the stores at all.

Anyway the point I want to use the same IabOpen class to support all Open app store, so I am trying to make something like:

  iab = IAB.new("open")
  iab:setUp("SlideME", slideme_key, "Yandex", yandex_key)

and from IapOpen.init method retrieve the list of app keys for each app store. Another solution could be created a new IapSlideMe class extending IapOpen and only overriding the init and isInstalled methods. This second option will follow your design in IAB plugin.

jdbc · June 2015

Wow impressive, care to submit PR in Github?

I have submit Gideros project and Android source code to https://github.com/jdbcdev/GiderosOpenIab

This provides the integration of OpenIab and Gideros IAB plugin. Finally in the Lua part you need to provide a list of (app_stores_names, app_key)

 
	iab = IAB.new("open")
	iab:setUp(NAME_GOOGLE, google_key,
                          NAME_SLIDEME, slideme_key,
			  NAME_APPLAND, appland_key
			)

I provided an example working on Google Play, SlideMe and AppLand, but it should work with Yandex and Aptoide too.

jdbc · June 2015

I was trying to integrate OpenIAB and Fortumo with Gideros IAB plugin.

It seems that IabFortumo class sets up the prices to "0.00".

How can I set up prices in Fortumo for my products?
