ah, ok, just have to enable the capability in the exporter in projucer [edit as explained in the metatdata ]
Donate to charity.
What is the best way to retry a failed InAppPurchases::Download? To call startDownloads or resumeDownloads, I need a Download* pointer.
Initially, if I call restoreProductsBoughtList with includeDownloadInfo, I get Download* pointers and can call startDownloads. 
But when a download fails, Listener::productDownloadFinished gets called, and the Download gets destroyed. From that point, how do I get a fresh Download* pointer, so I can call startDownloads or resumeDownloads again to retry the failed download?
It seems that the only two ways are:
-
purchaseProduct->productPurchaseFinished. But I don’t want to prompt the user to purchase again. -
restoreProductsBoughtList->purchasesListRestored. This is what I’m doing right now, but I don’t really want to restore IAP purchases.
Is there a better way? And is it possible to resume the download from the progress at which it failed?
[EDIT]
A different issue, but: Often when I use a Download* pointer in the purchasesListRestored callback, I get an EXC_BAD_ACCESS when calling Download::getStatus(). I’m calling it synchronously, but the Download* pointer already seems to be dangling.
