All the purchases you make are synced across all the devices which are logged in with same google account i.e. if you make a purchase on 1 device that purchase will be available with you on all other devices which are configured to same google account and if you try to purchase the same item again IAP takes care of that and won't let you do that. Still if you want to purchase the an item multiple time(like any healthpack in case of a game) then you need to inform playstore about the consumption of that item even if you haven't consumed it and in that case you need to keep track of that item yourself(use servers to keep track of the items) check this video: [this video]

Hey I'm also working on InApp Purchase since 10 days and I've successfully integrated in my existing app and ready to make it live. Initially when i had started doing this I've downloaded google InApp Billing Example called "Trivial Drive" from here [LINK] .

Recommends fips · 2015-11 · Stack Overflow · on “in-app subscription - is there a limit of inventory queries from apps?”

Not sure if you have found a solution to this, but this may help others: Yes there is a quota on the number of queries per day per application, the 2nd link you are referring to ( [LINK] ) states that there is a quota of 200,000 requests per day but you can request more if you run out of that. Also it is actually recommended by google to check every time your application starts using getPurchases as defined in v3 - that's why they optimized it. It is explained very well in this presentation which also provides example code: [this video] at 08:10.

Updating Your Application's Manifest In-app billing relies on the Google Play application, which handles all communication between your application and the Google Play server. To use the Google Play application, your application must request the proper permission. You can do this by adding the com.android.vending.BILLING permission to your AndroidManifest.xml file. If your application does not declare the In-app Billing permission, but attempts to send billing requests, Google Play will refuse the requests and respond with an error. To give your app the necessary permission, add this line in your Android.xml manifest file: <uses-permission android:name="com.android.vending.BILLING" /> Ref Im

I'm starting to make some in-app purchases on my future app, and i wish to ask some questions regarding the new API (3) of the in app billing library (shown here [LINK] ): google says ( here [this video] ) that there are no more unmanaged items. this means that in order to have multiple consumable items, the play store cannot hold a counter, so you need to either consume the purchase right when you put it in the app, or only when you need it. My question about it is how would you get the consumable items stay on multiple devices ? for example, if the user purchased 2 health potions, and because of the new limitations, they both are stored only on the app itself of one device, how could the end us
