I came across your library the other day because I need to update my billing library and yours seemed to be straight forward. I'm able to receive callbacks with product info ie. pricing and product ids, but when I initiate billingConnector.purchase or .subscribe neither go anywhere. Checked all cases as well, even copied your logic to a T & the only thing I can seem to get working is getting the info.

Hope to get some help, thank you.

Thanks for your work

I see your commit lastest a2e27e53c80edbd8fe18cd7d5899d6f435d876e8 but still does not release in jitpack

Could you please build lastest jitpack ?

onNoPurchasedProductsFetched listener is great listener, I want using this callback to trigger data

Please build jitpack help me.

• The deprecated methods have been replaced with the ones that came with Billing v5.
• With the offer options, the purchase is included.
• Upgraded compileSdkVersion to API 33
• Upgraded dependencies.

I recently updated the lib to version 1.0.6 and I am getting an error building with proguard, the error is as follows: Compilation failed to complete, origin: /storage/emulated/0/.sketchware/mysc/601/bin/classes_proguard.jar

In version 1.0.5, proguard worked normally.

What could be happening?

Thanks for creating this wrapper, it looks very useful. One question I have, is how can I use this library to correctly handle those new Cash payments that are now happening in Indonesia, Malaysia, etc? In those cases the user makes the purchase, then later goes to a convenience store to make the actual payment. Google recommends using the PurchaseToken to store information about a consumable on our own servers, which can then be granted later when the cash payment is made. It would be super helpful if you could add some sample code that correctly handles this type of situation. Thanks!

First of all, I'm new to the subject of programming, I managed to implement in-app-purchase almost successfully, but I'm facing some problems:

I have a problem that when I make a test purchase that will be denied after a few minutes, it already calls the OnProductPurchase event and gives the user the title of the product. How to solve? I would like to verify that the user has actually purchased by validating the purchase information before granting entitlement.

Also would you like to implement queryPurchasesAsync() is the library compatible? I didn't find any information in the README

Oh, one more thing, Lucky Patcher makes the purchase easily with just one click, does anyone have an efficient system against that?

Thank you very much in advance.

I have some app, which have subscription. User can buy subs, but how I can check is subs currently active.

Android App :- https://play.google.com/store/apps/details?id=com.shiv.shambhu

I'm testing the library 1.06 with an app installed on a device where the user has a non-consumable purchase already made in the past. This purchase is not restored. Restored purchase 1 out of 50 attempts

Hello. Thanks for your work! I ask you to call the onPurchasedProductsFetched event with an empty list if the user hasn't bought anything or the subscription has ended. This will greatly simplify the work, as well as reduce the amount of code, as it will make it possible to check the purchase correctly.

@Override
public void onPurchasedProductsFetched(@NonNull List<PurchaseInfo> purchases) {
    //   not called if there are no purchases
    boolean subscribedPremium = purchases.stream().anyMatch(a -> a.getSku().equals(InAppConstants.SKU_SUBSCRIBE_PREMIUM_ONE_YEAR));
}

The current implementation results in a double check.

@Override
public void onProductsFetched(@NonNull List<SkuInfo> skuDetails) {
    for(SkuInfo skuInfo : skuDetails) {
        if (skuInfo.getSku().equals(InAppConstants.SKU_SUBSCRIBE_PREMIUM_ONE_YEAR)) {
            // mBillingConnector.isPurchased(skuInfo) return PURCHASED_PRODUCTS_NOT_FETCHED_YET 
            // because purchases have not been synced yet
            // We cannot know for sure whether a purchase was made, 
            // so the subscribedPremium value will be false regardless of whether something was purchased or not.
            // If not, then everything is fine, but if yes, then we will disable the user's purchase 
            // and will wait for the onPurchasedProductsFetched event
            boolean subscribedPremium = mBillingConnector.isPurchased(skuInfo) == PurchasedResult.YES;

            // subscribedPremium == false
            // We cannot assign a value other than false, 
            // because we are not sure that the onPurchasedProductsFetched event will fire
        }
    }
}
@Override
public void onPurchasedProductsFetched(@NonNull List<PurchaseInfo> purchases) {
    // Reassigning a value to the subscribedPremium variable
    boolean subscribedPremium = purchases.stream().anyMatch(a -> a.getSku().equals(InAppConstants.SKU_SUBSCRIBE_PREMIUM_ONE_YEAR));
}

Is it possible to do this?

The error below keeps occurring I've searched online for a solution but nothing is working.

java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/common/collect/ImmutableList; at games.moisoni.google_iab.BillingConnector.purchase(BillingConnector.java:653)

Hey thanks for the update to billing V5, it works perfectly!

Just a small issue i noticed that when i use billing V5 compared to the previous V4 the size of the compiled apk is increased by approx 8mb

is anyone else having the same effect? Thanks

Hello, I recently tried using this library and am having some issues using it. I have one in-app purchase that I want to use your library with. The in-app is a remove ads non-consumable that would only ever be purchased once by the user (If bought in the past then I'd want the purchase to be verified and handled instead of purchased again).

Whenever I try to make a purchase I see this:

I filtered Android Studio to show me only BillingConnector:

? D/BillingConnector: Billing service: connecting...
? D/BillingConnector: Billing service: connected
? D/BillingConnector: Query Product Details: data found
? D/BillingConnector: Subscriptions support check: success
? D/BillingConnector: Query SUBS Purchases: the list is empty
? D/BillingConnector: Query IN-APP Purchases: the list is empty
? D/BillingConnector: Billing API version is not supported for the type requested. Response code: 3 <-- after billingConnector.purchase

I followed the instruction in the readme for setting everything up.

implementation 'com.android.billingclient:billing:5.0.0'
implementation 'com.github.moisoni97:google-inapp-billing:1.1.1'
coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.1.5'

billingConnector = new BillingConnector(activity, LICENSE)
					.setNonConsumableIds(Collections.singletonList(SKU))
					.autoAcknowledge()
					.autoConsume()
					.enableLogging()
					.connect();
...

billingConnector.setBillingEventListener(new BillingEventListener() {
			@Override public void onProductsFetched(@NonNull List<ProductInfo> productDetails) {
				for (ProductInfo pinfo : productDetails)
				{
					Logd("Fetched product " + pinfo.getProductDetails().getProductId());

					...
				}
			}
			@Override public void onPurchasedProductsFetched(@NonNull ProductType productType, @NonNull List<PurchaseInfo> purchases) {
				for (PurchaseInfo pinfo : purchases)
				{
					Logd("Fetched purchased product " + pinfo.getPurchase().toString());

					...
				}
			}
			@Override public void onPurchaseConsumed(@NonNull PurchaseInfo purchase) {}

			@Override
			public void onProductsPurchased(@NonNull List<PurchaseInfo> purchases) {
				for (PurchaseInfo pinfo : purchases)
				{
					verifyPayload(pinfo.getPurchase(), new Runnable() {
						@Override
						public void run() {
							Logd("Handling purchase payload");
							
							...
						}
					});
				}
			}

			@Override
			public void onPurchaseAcknowledged(@NonNull PurchaseInfo purchase) {
				/*Callback after a purchase is acknowledged*/

				verifyPayload(purchase.getPurchase(), new Runnable() {
					@Override
					public void run() {
						Logd("Acknowledge purchase payload");
	
						...
					}
				});
			}

			@Override
			public void onBillingError(@NonNull BillingConnector billingConnector, @NonNull BillingResponse response) {

				Logd(response.toString());
			}
		});

...

billingConnector.purchase(activity, SKU); // I have this elsewhere in my code

I also tried updating to com.android.billingclient:billing:5.1.0 and that didn't change anything.

Do you have any ideas why this issue is happening?

Edit: My minSdkVersion is 23 if that helps

onPurchasedProductsFetched is called twice on connect(). One time with purchases empty and once with purchases as expected (in case the user purchased). The worst thing is that there's a race condition so you can't even write a logic based on skipping the first time as sometimes this is the correct data, followed by the false data.

It doesn't help to connect before setting the listener or after.

So I've successfully loaded all other items but when I activate & load a Subscription it doesn't load. When I try to subscribe it also says it doesn't exist. Do apps that have Subscriptions need to be on the PlayStore to work I've followed all the steps & nothing.

First time using this library, I try to implement it as it says in README. but when I purchase onProductsPurchased was called with empty purchases, this is the only callback I got back.

I setup the billingConnector like this.

billingConnector = BillingConnector(this, base64Key)
            .setConsumableIds(listOf(id1))
            .autoAcknowledge()
            .autoConsume()
            .enableLogging()
            .connect()

what am I missing here?
