Using the SDK tester, I have no sense for how long it takes for these APIs to return results. Should we put up an indeterminate progress indicator when waiting for results to come back from either initiateItemDataRequest, or initiatePurchaseUpdatesRequest?
Hi Thibault, The SDK tester is a developer tool that allows users of the Amazon Mobile App SDK to test their implementation in a production like environment before submitting it o Amazon for publication. Returning results of Amazon API's in Testing or production environment is almost similar. It depends on the factors of Internet speed and connectivity. We don't support any indeterminate progress indicator when waiting for your results from Amazon API's.
