in-app-billing

问题 I would like to know what the maximum number of items that can be placed in In App billing for both Android and iphone. I seem to remember reading around 3000 but I cannot find the reference. Also if 3000 is the maximum what are the legitimate way to get around this. My app will sell content and I thought a possible way around the problem would be to have a central app that shows the content, then a number of different libraries where you can purchase the content. Would that be a viable work

问题 I'm attempting to make a free app upgradable to the "paid" version using in-app billing. I used code from this tutorial to handle the billing as the one on the official developer site is too complex and messy to follow for a simple flow like mine. My code to do the upgrade works fine. The problem comes when I try to add something to check if the user has already purchased but has lost their purchase data either by reinstalling or by clearing the data (I don't care which). On app startup I

问题 I am using in-app billing from Google for Android for the first time. However, if a user doesn't have an internet connection or no google framework installed (e.g. with custom roms) and probably other occasions (like wrong/old market version etc.) This method (inside the provided IabHelper class): mContext.bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"), mServiceConn, Context.BIND_AUTO_CREATE); Doesn't work and no service get's established.

问题 I spent a week looking for solution to upgrade/downgrade subscriptions on Android InAppBilling . There's a reference page about this function: http://developer.android.com/google/play/billing/billing_reference.html Google said that we could use getBuyIntentToReplaceSkus() method, but I couldn't found any documentation about that in its signature. I can't also see it in IInAppBillingService.aidl file that Google provided. Is there any one who may help me? 回答1: Just use my aidl file and be

问题 I'm currently testing my InApp billing mechanism (using the InApp Billing version 3 API, therefore taking the TrivialDrive example as reference). I have one managed item, which is upgrade to premium version. Now, purchasing the item with my test account works, but when I do a cancellation of the entire order in Google checkout afterwards, my code still tells me that the item is purchased an therefore grants the premium features. Here is how I check for the purchase in my MainActivity. I do

问题 On this bug report on github https://github.com/googlesamples/android-play-billing/issues/2#issuecomment-305380836 we were asked to raise the issue here. The issue is simple.

The app updates and now the app is under abc@gmail.com and the user has lost the purchase. This happens a lot when using staged rollouts. Main issue, as
