I add an SKU as an auto-renewable subscription on App Store Connect. I have codes below in the main class.
public static final String SKU_TW_1_YEAR="com.visionx.tw.subscribe.1year.2";
Purchas iap = Purchase.getInAppPurchase();
// Define a receipt loader
iap.setReceiptStore(createReceiptStore());
iap.subscribe(SKU_TW_1_YEAR);
@Override
public void itemPurchaseError(String sku, String errorMessage) {
ToastBar.showErrorMessage("!subscribe_failure:"+errorMessage);
}
The callback procedure itemPurchaseError is called with an error message:
An unknown error occurred
Are there any procedures I can follow to check the settings of App Store connect or debug for solving this problem?
I have a screenshot of the SKU setting on App store connect for checking.
I run my App on my iPhone 7 through Xcode for subscribing my pdoduct. The console on Xcode shows messages below.
