我正在尝试在我的 android 应用程序中实现应用程序购买。我正在使用应用内计费 API v3 来实现 IAP(应用内购买)。作为参考,我正在关注 Google 提供的 trivialdrive 示例。在launchPurchaseFlow
方法
public void launchPurchaseFlow(Activity act, String sku, String itemType, int requestCode,
OnIabPurchaseFinishedListener listener, String extraData) {
checkSetupDone("launchPurchaseFlow");
flagStartAsync("launchPurchaseFlow");
IabResult result;
if (itemType.equals(ITEM_TYPE_SUBS) && !mSubscriptionsSupported) {
IabResult r = new IabResult(IABHELPER_SUBSCRIPTIONS_NOT_AVAILABLE,
"Subscriptions are not available.");
if (listener != null) listener.onIabPurchaseFinished(r, null);
return;
}
try {
logDebug("Constructing buy intent for " + sku + ", item type: " + itemType);
Bundle buyIntentBundle = mService.getBuyIntent(3, mContext.getPackageName(), sku, itemType, extraData);
int response = getResponseCodeFromBundle(buyIntentBundle);
if (response != BILLING_RESPONSE_RESULT_OK) {
logError("Unable to buy item, Error response: " + getResponseDesc(response));
result = new IabResult(response, "Unable to buy item");
if (listener != null) listener.onIabPurchaseFinished(result, null);
return;
}
PendingIntent pendingIntent = buyIntentBundle.getParcelable(RESPONSE_BUY_INTENT);
logDebug("Launching buy intent for " + sku + ". Request code: " + requestCode);
mRequestCode = requestCode;
mPurchaseListener = listener;
mPurchasingItemType = itemType;
act.startIntentSenderForResult(pendingIntent.getIntentSender(),
requestCode, new Intent(),
Integer.valueOf(0), Integer.valueOf(0),
Integer.valueOf(0));
}
catch (SendIntentException e) {
logError("SendIntentException while launching purchase flow for sku " + sku);
e.printStackTrace();
result = new IabResult(IABHELPER_SEND_INTENT_FAILED, "Failed to send intent.");
if (listener != null) listener.onIabPurchaseFinished(result, null);
}
catch (RemoteException e) {
logError("RemoteException while launching purchase flow for sku " + sku);
e.printStackTrace();
result = new IabResult(IABHELPER_REMOTE_EXCEPTION, "Remote exception while starting purchase flow");
if (listener != null) listener.onIabPurchaseFinished(result, null);
}
}
在上面的代码getBuyIntent
中并不期望nonce
,我们有额外的数据,我们在其中传递 developerpayload(特定于每个购买项目)。在这里,我无法弄清楚如何传递 nonce,因为它是在 API V2 中传递并作为成功购买的响应而收到的。nonce
V3中不需要吗?
谢谢
