SDKs

hello, I am currently developing with flutter.  All the steps below have been completed and the APK has been uploaded to the Google Play Store and tested in closed testing https://www.revenuecat.com/docs/creating-play-service-credentials#1-link-to-a-google-developer-project The payment screen does not appear and an error occurs. ```e.details: {code: 4, message: One or more of the arguments provided are invalid., readableErrorCode: PurchaseInvalidError, readable_error_code: PurchaseInvalidError, underlyingErrorMessage: There is no current Activity}```I've deleted all Google Play Store accounts on my device and adde

I am currently trying to handle purchases using RevenueCat. Everything seems to work fine, except my completion handler does not execute properly. I am currently running iOS16 -- the last of my logs look like this:  2023-07-07 21:46:29.274573-0400 main[1521:253544] [purchases] INFO: 💰 Finishing transaction 'x' for product 'x'2023-07-07 21:46:29.274658-0400 main[1521:254084] [network] DEBUG: ℹ️ Serial request done: POST receipts, 0 requests left in the queue2023-07-07 21:46:59.258445-0400 main[1521:254760] [tcp] tcp_output [C6.1.1.1:3] flags=[R.] seq=4201476122, ack=584019737, win=2047 state=CLOSED rcv_nxt=584019737, snd_una=4201476045As you can see, the transaction does not completely finish and thus I cannot properly set the user’s state to subscriptionActive = true. The purchase however, will successfully show up on my dashboard. Does anyone know a way around this? I’v

Hi there,I’m running into a problem where purchases do succeed, but the Purchases.shared.purchase(...) completion block is never called.I do see INFO: 💰 Finishing transaction in the logs, but the completion block itself is never called.Purchases.shared.purchase(package: package) { (transaction, customerInfo, error, userCancelled) in // Never called}I’m trying with a sandbox account on a real device. The same code seems to work for one of my other apps. I’m using purchases-ios 4.17.9. If after a purchase I do a restore purchase action, the entitlement is there for this customer. This confirms that the purchase does succeed.Any idea why this is happening?

Does the RevenueCat SDK cache products between app starts? I can’t find anything in the documentation about this. Use case: user opens app while device is offline and hits a paywall. While they won’t be able to proceed with the purchase, it would still be great to display prices.

 Hi, RevenueCat skd is not able to fetch the offers packages, I already check the id and there are the same ( I imported from appStore connect)I ran the app in a device and the simulator,  I’m able to fetch the customer info but not the offers.In the logs I can see the offers name but RevenueCat is no able to bring them.See Xcode Logs with the name of the offers:2023-06-07 17:43:31.500572-0500 RevenueCatSharpen[24587:4211535] [Purchases] - DEBUG: ℹ️ No existing products cached, starting store products request for: ["year_subscription", "sharpen_threeM_5M_0"]RevenueCatSharpen[24507:4202388] [Purchases] - DEBUG: ℹ️ Found an existing request for products: ["sharpen_threeM_5M_0", "year_subscription"], appending to completion Se

I am using android kotlin sdk for fetching the offerings (google play, IAP products). But the fetching of offering is very slow (~15s). In my application users can see the list of products as soon as they open the app. So showing a loading screen for 10-15 seconds until i can show products is giving a bad user experience. I tested the public revenuecat apis separately and they are pretty fast (<0.3s).I am using `Purchases.sharedInstance.getOfferingsWith` as instructed in the docs.I am initializing the SDK at application start.From logs i can see a 10s delay “Updating pending purchase queue” and “starting http requests”Logs:21:55:08.744 D/[Purchases]: ℹ️ Debug logging enabled21:55:08.745 D/[Purchases]: ℹ️ SDK Version - 5.0.0-rc221:55:08.745 D/[Purchases]: 👤 Initial App User ID - null21:55:08.745 D/[Purchases]: 👤 Identifying App User ID: $RCAnonymousID:QQQQQQ21:55:08.745 D/[Purchases]: ℹ️ Deleting

I am getting the following error with the code below: ‘java.lang.NullPointerException: Attempt to invoke virtual method 'boolean com.revenuecat.purchases.EntitlementInfo.isActive()' on a null object reference’ Purchases.getSharedInstance().getCustomerInfo(new ReceiveCustomerInfoCallback() { @Override public void onReceived(@NonNull CustomerInfo customerInfo) { Log.i("RevenueCat", String.valueOf(customerInfo.getEntitlements())); Log.i("RevenueCat", String.valueOf(customerInfo.getEntitlements().getAll())); if (customerInfo.getEntitlements().get(premiumEntitlementID).isActive()) { sharedPreferences.edit().putBoolean("premium", true).apply(); } else { sharedPreferences.edit().putBoolean("premium", false).apply(); } }

Hi, I have been developing an app for iOS, and I can get the free trial as intro price in getOfferings response of the SDK. Now, I have upgraded to SDK 6 and trying to do the same on Android. The free trials are there in intro price, but they are returning wrong numbers. There are free trials as subscription options which have right number of days. Is this a bug or expected? Thank you in advance!

We are using visitorId from Fingerprint to identify the user. and it is used as the only user account on our system.Purchase setupPurchases.configure({             apiKey: REVENUECAT_API_KEY,             appUserID: visitorId, //We are using Fingerprint to identify the user.             observerMode: false,             useAmazon: false,             usesStoreKit2IfAvailable: true,           });User A using device1 with identifier visitorID1 and AppleID1 makes the paymentIn case of used User A using device 2 with identifier visitorID2 and AppleID1 can restore the purchase. On the backend we can swap subscriptions between visitorID1 and visitorID2

I’m adding iOS Introductory Offers, and I would like to test before going live. However, when following the guide in the docs, the `discounts` field on the product is an empty array. How do I test this introductory offer before going live? Example of the code I’m using for reference:const purchaseDiscountedIOSPackage = async (purchasePackage) => { const product = purchasePackage.product; const discount = product.discounts?.[0]; // product.discounts is empty if (!discount) { throw new Error('No discount found on producct'); } const paymentDiscount = await Purchases.getPromotionalOffer(product, discount); if (!paymentDiscount) { throw new Error('No payment discount'); } try { const purchaseMade = await Purchases.purchaseDiscountedPackage(pkg, paymentDiscount); return purchaseMade.customerInfo; } catch (e) {

 Hi,I ran into an issue while implementing subscription for Android. I am trying to allow user to upgrade one a Basic plan ($10) to Pro plan ($40). Here, both Basic and pro plan is a monthly plan.I bought Basic plan, then I wanna upgrade it to Pro plan, but it returns me “Couldn't find existing purchase for SKU”.In my understanding, the product id (entitlement) is the SKU. Please correct me if am wrong. Any help would be greatly appreciated. 

Thank you for creating a crazy useful package.I use this android library com.revenuecat.purchases:purchases:6.4.0.Unexpected crash in some users.The error log is here.Fatal Exception: org.json.JSONException: Value  of type java.lang.String cannot be converted to JSONObject       at org.json.JSON.typeMismatch(JSON.java:112)       at org.json.JSONObject.<init>(JSONObject.java:172)       at org.json.JSONObject.<init>(JSONObject.java:185)       at com.revenuecat.purchases.common.diagnostics.DiagnosticsFileHelper.readDiagnosticsFile(DiagnosticsFileHelper.kt:39)       at com.revenuecat.purchases.common.diagnostics.DiagnosticsSynchronizer.getEventsToSync(DiagnosticsSynchronizer.kt:86)       at com.revenuecat.purchases.common.diagnostics.DiagnosticsSynchronizer.access$getEventsToSync(DiagnosticsSynchronizer.kt:19)       at com.revenuecat.purchases.common.diagnostics.DiagnosticsSynchron

There is a delay of about 5 seconds from function call and popup displayed on ios. Is there solution for this?

Hi guys, We’re having issues with the purchase callback never being called for some users. This post came closest to the same issue, but didn’t have a clear answer to how to resolve or what the cause could be.The annoying this is that I can’t reproduce the issue. What happens for certain users, is that they hit our “Subscribe” button, and the loading icon that’s shown gets stuck because the callback never returns. This issue has to have to do with the call to func purchase(package: Package, completion: @escaping PurchaseCompletedBlock) , since in all other cases the loading icon would disappear. Relevant CodePurchasesManagerPurchasesManager is a wrapper Singleton class for called RevenueCat’s Purchases./// Purchase the given package and call co

I’m trying to test the Restore Purchase functionality locally with a sandbox user for my macOS desktop app but nothing seems to happen.  Here is my code: Purchases.shared.restorePurchases { purchaserInfo, error in    if purchaserInfo?.entitlements.all["Premium"]?.isActive == true {        NotificationCenter.default.post(name: NSNotification.Name("SubscriptionActive"), object: nil)        closeAction()    }    isLoading = false}  

currently, the “package.storeProduct.description” will be the translation mathing the device’s language.can i choose another translation (from the google play\app store translations) to show?

I am facing trouble to fetch experiments in flutter. 

I am getting this error initialising the RFevenueCat connection whilst running in Windows in Adroid Studio in an NExus 6 API 33 emulator Billing is not available in this device. DebugMessage: Billing service unavailable on device.. ErrorCode: BILLING_UNAVAILABLE. 

I have an iOS experiment that I’d like to manually test if both control and treatment work and looks as expected before going to production. I’ve made the necessary changes and am ready to release the new version after testing with both offerings returned by Revenuecat.As far as I can see, the only way is to start the experiment as a whole to be able to test different treatments. This means my production customers will be bucketed in this experiment without having necessary changes in their build (previous version).How can I allowlist my userId in an Experiment?Thanks

Hi,I’m using revenue cat in a flutter app to manage subscriptions. Users are not logged in, I’m only using anonymous App User IDs. It works like a charm.However, a user has subscribed on his ipad and cannot use the entitlement on his iphone. He has an error when he tries to subscribe to the same entitlement.If I add the restore purchases method, will that solve this issue ?Or do I need to log in users ?Thank you for your help

Hi all,So i’ve been implementing rev cat recently, and we’re about coming to the end of development ready to push it.But 1 out of 3 of our test devices wasn’t able to fetch offerings for some reason.We left it whilst doing other stuff and then realised another device when logging out of our app with one account and logging back into another was then unable to fetch offerings as well. Even when doing full restarts, new builds etc. That device just wasn’t able to get offerings anymore.To be exact in the console i get “unexpected back end error”.I’ve attempted to redo everything in the list of “why are offerings not showing and trying to look for similar questions asked her but to no avail. Any help?

HiI am stuck in fetching the subscription plans in the android native app. i have followed your documentation but still not able to fetch the subscriptions. Kindly help in thisGetting this error message😿‼️ Error fetching offerings - PurchasesError(code=ConfigurationError, underlyingErrorMessage=There are no products registered in the RevenueCat dashboard for your offerings. If you don't want to use the offerings system, you can safely ignore this message. To configure offerings and their products, follow the instructions in https://rev.cat/how-to-configure-offerings.

I’m somewhat new to this and not a seasoned developer. My app has iOS/Android versions and now a web version. For the web version I’m using the RevenueCat REST API and trying to implement the same functionality as in the mobile versions via the SDK. It seems that while there are similar functionalities between them, but the contents, format, and structure of the response is different. Specifically, I am looking at the following:SDK: Purchases.shared.getCustomerInfoAPI: Get or Create Subscriber (GET v1/subscribers/{app_user_id}) These two items appear to be analogs to get a customer/subscriber. However there is substantially improved information available in the SDK version. For example, the SDK indicates which subscriptions/entitlements are active, whereas in the API I need to manually determine this based on the full list of subscriptions (subscriber.subscriptions.{product_id}.{expires_date}.
