  • Problem Description

    By following the recommended tutorial and exporting Crosswalk using Intel Xdk there are many problems with the Official IAP Plugin. These are the 6 I came across, there might be more.

    Bug 1. IAP expression: ProductName(productid). Does not display product name (when not purchased product)

    Bug 2. IAP expression: ProductPrice(productid). Does not display price. (when not purchased product)

    Bug 3. When purchasing product and googles purchase page opens, closing the googles page causes the whole app to freeze (Not every time. It might be 2nd time the purchase screen is opened or more). Clicking the purchase button works and the purchase screen pops up, the rest of the app freezes when the Googles purchase screen is closed.

    Bug 4. IAP properties: Test mode. Test mode is not working and purchases the product when Test Mode is set to yes.

    Bug 5. IAP conditions: Has product is continued to be returned when product has been refunded through google play.

    Bug 6. IAP conditions: Invert Has product continues to be returned when user does have product.

  • Bug 1 & Bug 2: Store available and store listing have to come back true in order to get these. When first starting up the project they don't always get returned immediately. I put in a loop where it would attempt to get the listing. If it failed, it would wait 2 seconds and try again. If it failed 5 times, it would assume that the store simply wasn't there and proceed. Yes it's an issue but I could find no other way to get it to work consistently.

    Bug 3: don't have this problem

    Bug 4: Correct AFAIK. I've tried with test mode on and off and makes no difference. If you want to do test purchases, you'll have to set up beta testers and add the email they use to log into google. Then, it will do the purchases but not deduct money from any account.

    Bug 5. I believe this has to do with Android caching the purchase info. If you cancel the purchase in the Google Dev Console it may take a while for it to get to the Android device. One test I haven't done is to cancel the purchase then turn the phone off and back on to clear that cache. Otherwise, it will eventually come back as false.

    Bug 6. I haven't tried an 'inverse' as I can't even consistently get the has product result on starting my app.

    Here's the thread I've been trying to get help on:

  • Ashley, bump since the other thread was closed down.

  • Just spent like 30 minutes making a bug report about IAP but I got logged out so I'm just going to reply here. When I have the IAP in a project I can no longer preview on android (over wifi) at all, it just crashes. This is sudden and I can reproduce the error in a completely empty capx with the IAP plugin added in the project. As soon as I remove it it works fine. This problem doesn't show up in preview on PC or iOS. It seems to have something to do with the cws-buy.js file generated by the IAP plugin.

    Furthermore I had to switch to a 3rd party IAP plugin because I was experiencing many of the bugs in this post. It's a shame because 3rd party plugins don't have the best support and I would really like to use the included plugins exclusively.

    I know this isn't proper bug report format but I hope this info helps resolve this.
