Thanks a lot for this man... Please, can u make a video on subscription and also, can the same code in the server be used to verify subscription purchase?
Bro! Please, when will you make a tutorial on subscription billing... We really need the video... No video has been comprehensive and efficient as the one you did for the in app purchase... We are hoping that you will release the subscription billing very soon
Excellent tutorial. Upgraded existing subscription code that I had become unfamiliar with overtime to Billing Lib 4 quite easily with your video. A lot of nasty legacy code to the bin..!
Very good and detailed tutorial. I have one comment though. From what you have accomplished here it is clearly visible that Firebase service, which is paid service in BLAZE plan after all, is not needed at all. Its whole functionality is just to log the purchases. Probably Firebase (or other external backend server) is needed when handling the subscriptions, but this type of purchase you haven't dealt with in this video. Am I correct? Although it is very good to learn how to work with the backend server anyway 🙂
As i understand, we need to give item to user instead of toast message. Question is... If I have 2+ different products, how can I figure out which product the user bought?
Hello, all you have to do is to loop through all the product ids that was processed in the verifyPurchase() method: AcknowledgePurchaseParams acknowledgePurchaseParams = AcknowledgePurchaseParams.newBuilder().setPurchaseToken(purchase.getPurchaseToken()).build(); billingClient.acknowledgePurchase( acknowledgePurchaseParams, new AcknowledgePurchaseResponseListener() { @Override public void onAcknowledgePurchaseResponse(@NonNull BillingResult billingResult) { if(billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) { for(String sku: purchase.getSkus()) { Log.e("MainAct", "Product ID" + sku); } } } } );
This tutorial helped me alot, thank you! Very well made. I´m new to programming so i have a question, i want to give my users coins via purchases. so i put the method to collect coins into the onPurchaseUpdated method (hope thats right). It works with one InApp Item, but if ill add another i dont know where to put in the collectable coins.. :/ i´ve put the second item into the getProductDetails method and made a new textView, Button and itemInfo for it (again, hope thats the correct way). how can i get different items for different purchases?
Hello, If the purchase was not acknowledged yet, you just have to wait 3 minutes and that message will go away. Or if you want to test purchasing an item multiple times, use consumeAsync() instead.
Hi great tutorial everything is very clear, thanks!, I am facing a problem that the products do not show on the activity, Did exactly the same as you did, I do not have any errors either, what can I do?
Can you do a part two that uses a mysql server for verification? My goal (and I'm sure the same can be said for others) is max ROI, using firebase pay as you go can eat into that ROI. If a user owns their own server(s), then by using php scripts to communicate with the MySql database, that work can be done with owned resources and cut out third party services. Great video and easy to follow!
Thank you. This is mainly for In-App products. For subscriptions, it requires some modifications and additional steps. A video on that will be released soon.
Sometimes my purchases can't be consumed... usualy when i make first purchase after cold starting app. Any idea? Logs says: W/BillingHelper: Couldn't find purchase lists, trying to find single data.

Thanks a lot for this video ! I just did not understand in what part of the process you handle the product to the user. For instance, if I offer a simple purchase to remove ads from the app, based on a user profile param (e.g. boolean isPremium = true), where do I set the "isPremium = true", and also how do I retrieve the item that got purchased that was made ? Thanks in advance :)
Hello, if your app constantly have new products, their info should be stored in a database. Then you will retrieve each product info from the data base. When the user purchase an item, you will compare the purchased product with all the other products and determine whether they are consumable or non-consumable. If your app products do not change often and do not want to use a database, then you can put all your product information in the app and do the same.
How can I fix this error in functions logs>>> : Value for argument in documentPath must point to a document, but was "purchases/$(purchasesInfo/purchasesToken)" . Your path does not contain an even number of components.

Hi. Great tutorial. My question is that the database rules allow any user to delete or overwrite the database. Any ideas or help on how to configure the rules to prevent this from happening without affecting the validation of the purchase tokens? Thanks in advance.

Hello, 1) Add the account you are using for the test in the Google Play Console 2) Uninstall the app on the device 3) Go to the app settings on the phone and clear all the data/cache for the Google Play app 4) Go to the Google Play App and log in with the testing account you added on the Google Play Console 5) Run the app again Extra: Make sure the device has the Google Play app.
@@lanreakintayo3443 Ok. Are you using the emulators? It happens sometimes when you are using the emulators - simple fix should just be emptying the memory and cache from the Google Play App. Try on a phone first to see if it is working properly. Then: 1) Rebuild the project with a different version code and upload a new release. 2) Repeat the steps from earlier, but this time, run the new version first then uninstall it manually on the emulator.
You are not correctly verifying the in-app purchase. You should call the Google API to check if the purchase token is valid. When you not check this, I can send random tokens to your backend, and it responds that the purchase is valid.
@@akashdeepkashyap9806 The concept is the same as Firebase, you'll need to use AWS Lambda + API Gateway for the API logic and maybe AWS RDS for data storing. 1. Create AWS Lambda functions that accept incoming data and store it in a database like RDS 2. Create API using API Gateway 3. When the API is called, it'll trigger the Lambda and then everything is similar to Firebase.
@@Codeible As In FireBase Integration we setup our application in it. Now my ques is how this API gateway's API will be triggered if we go with your API-gateway & lambda function approach .
As of January 1, 2022, that service fee is equivalent to: For developers who are enrolled in the 15% service fee tier, the service fee is: 15% for the first $1M (USD) of earnings each year, 30% for earnings in excess of $1M (USD) each year.

For automatically renewing subscription products purchased by subscribers, the service fee is 15%. support.google.com/googleplay/android-developer/answer/112622?hl=en
I wonder if keep acknowledge code in client side. it possible that someone could prevent acknowledgePurchase() ( reverse engineering ) they could easily get refund and the server considers them as a legit purchase.

Please, how am I going to solve this issue? I've checked stackoverflow and I've followed all the steps needed. Yet, It is still bringing out this same error message
Hello,
1) Add the account you are using for the test in the Google Play Console
2) Uninstall the app on the device
3) Go to the app settings on the phone and clear all the data/cache for the Google Play app
4) Go to the Google Play App and log in with the testing account you added on the Google Play Console
5) Run the app again
Extra: Make sure the device has the Google Play app.
I've done what you said I should do, but the error persists
@@lanreakintayo3443Did it work before? and then this issue occur?
It didn't work at all.. But the products were able to load from the google play console
@@lanreakintayo3443 Ok.
Are you using the emulators? It happens sometimes when you are using the emulators - simple fix should just be emptying the memory and cache from the Google Play App.
Try on a phone first to see if it is working properly. Then:
1) Rebuild the project with a different version code and upload a new release.
2) Repeat the steps from earlier, but this time, run the new version first then uninstall it manually on the emulator.
what a great tutorial, thanks for the info :D
You are not correctly verifying the in-app purchase. You should call the Google API to check if the purchase token is valid. When you not check this, I can send random tokens to your backend, and it responds that the purchase is valid.
ya.. I was also thinking about that.....

Hi 😊🎉 38:28
Can we use AWS cloud instead of firebase
Yes
@@Codeible could you please eloborate how do we integrate aws cloud function for RTDN with google play billing.
@@akashdeepkashyap9806 The concept is the same as Firebase, you'll need to use AWS Lambda + API Gateway for the API logic and maybe AWS RDS for data storing.
1. Create AWS Lambda functions that accept incoming data and store it in a database like RDS
2. Create API using API Gateway
3. When the API is called, it'll trigger the Lambda and then everything is similar to Firebase.
@@Codeible As In FireBase Integration we setup our application in it. Now my ques is how this API gateway's API will be triggered if we go with your API-gateway & lambda function approach .
@@akashdeepkashyap9806 The same way as in the video.
Once you have the API, you call it.
Is it good for google play billing v5?
please help
The concept is similar with minor adjustments
@@Codeible can you tell me the changes please...
@@Rohan_is_discovering Sure, this post gives all the code changes.

How much Google charges for InApp purchases?
As of January 1, 2022, that service fee is equivalent to:
For developers who are enrolled in the 15% service fee tier, the service fee is:
15% for the first $1M (USD) of earnings each year,
30% for earnings in excess of $1M (USD) each year.
For developers who are not enrolled in the 15% service fee tier, the service fee is 30%.
For automatically renewing subscription products purchased by subscribers, the service fee is 15%.

Good afternoon.
Tell me why all payments are returned after three days
Hello, payments may be returned after 3 days if you have not acknowledged the payments.
@@Codeible Right. Question. In the video, the payment confirmation code was described?
@@ЕвгенийВорожбянов-г7б Yes,
@@Codeible As I understand it, what you wrote in onResume is payment verification
@@ЕвгенийВорожбянов-г7б You need to do it in the onPurchasesUpdate callback
Video reach is 200 like
Can you provide source file of this please
Hello, you can download the project here: codeible.com/coursefiles/googleplayinapp
can you please create a subscription?
Pleaseee, make the subs video
like the video
doesnt work at all
Yuck, Java
I wonder if keep acknowledge code in client side. it possible that someone could prevent acknowledgePurchase() ( reverse engineering ) they could easily get refund and the server considers them as a legit purchase.
why the toast message not show in onAcknowledgePurchaseResponse ? thank you
Oh, that is because the toast is overridden by the purchase flow. You can use Log to display message in console.
@@Codeible thank you !
