问题
I have an Android app with in-app subscriptions.
While testing, I used a google account to "buy" a test subscription - the ones that last for 24 hours and don't incur in actual billing. It worked fine a few times, but my last "purchase" is stuck and I can't cancel it.
When I try cancelling it via Google Play store, either the app or the website, I get these extremely unhelpful error messages: "An unexpected error occurred. Please try again later".
When I try cancelling it via Google Play Developers API (https://developers.google.com/android-publisher/api-ref/purchases/subscriptions/cancel) it just returns a 500 HTTP response code and no messages.
That subscription has been active for over a month. It renews itself every 24 hours and seems like it will never stop.
Also, the getPurchases() method returns me the subscription ID in the INAPP_PURCHASE_ITEM_LIST array, but its corresponding item in the INAPP_PURCHASE_DATA_LIST array is completely empty. There's no orderId, no purchaseToken, nothing. And I don't mean these fields are null or empty strings. I mean they aren't even listed in the JSON array.
Unfortunately this is happening on my main Google account. So now, every time I need to test something related to subscriptions in my app, I need to remove my main account from my device and use another Google account. Otherwise, my app will try to load this bugged subscription and give an error. It's very annoying.
Has anyone experienced this before? Any ideas how to make this test subscription disappear for good?
P.S.: I tried posting this on the official Android Developer forums, but the moderators seem to have either rejected my post or they haven't got around to it yet. It's been a month, though.
