问题 So I have a billing client which I instantiate with billingClient = BillingClient.newBuilder(this).setListener(this).build(); I then call billingClient.startConnection(new BillingClientStateListener() { @Override public void onBillingSetupFinished(int responseCode) { //TODO: use this for stuff com.android.billingclient.api.Purchase.PurchasesResult result; result = billingClient.queryPurchases(BillingClient.SkuType.SUBS); Timber.d(result.toString()); } @Override public void

问题 I just started beta testing the 2.0 update to the billing library for the Play Store and a lot of my users are getting this error Google Play In-app Billing API version is less than 3 .

问题 I'm very confused on how in-app billing works. I've read the documentation and I must have missed something because I don't understand the final step I need to implement into my application to make this work. The in-app billing works great, however, if a user uninstalls my app and installs it again at a future date, my application doesn't know how to determine if the in-app purchase has previously been made. Here's a snippet from my main class where I attempt to handle all of this: @Override

问题 I'm trying to add in-app purchase for my existing published app that didn't previously have billing permission. I've uploaded an updated APK with billing permission, but didn't activate it since I don't want to publish this draft. However, I can't add in-app product - it still says "the current application version does not use the BILLING permission". Any way to solve/work around this problem? 回答1: Change Android version code in Androidmanifest.xml file. android:versionCode="1" suppose if

问题 I was wondering how to detect a refund, or any type of cancelation of an in-app purchase(not a subscription and not a consumable). I'm currently making my test and when I refund a test in google like that : The purchase is still present in billingClient.queryPurchaseHistoryAsync() (even in queryPurchase() ). How can I detect such changes and how can I disable my app for refunded users? Thanks in advance. 回答1: Have to tried this function PurchasesUpdatedListener Listener interface for purchase

问题 I have two version of my app Paid Version Free Version Now in free version I disabled some features that are available only in the paid version. So what i want is when user taps on any of those disabled features, the in-app purchase window should pop up and when the transaction completes the free version of the app should get replaced by the paid version. Can you please tell me what would be the right way to do that. 回答1: Free version to paid version scenario: To understand why you should

问题 I am looking at the Android in-app billing tutorial here: http://developer.android.com/guide/google/play/billing/billing_integrate.html and they have an instruction to implement the iMarketBillingService. But I saw in another example that the ServiceConnection method was implemented. Which one should it be? I am having confusion because I am trying to do something like this: Bundle request = makeRequestBundle("CHECK_BILLING_SUPPORTED"); Bundle response = mService.sendBillingRequest(request);
