在代码之后,我在论坛中看到了与“返回”相同的问题
if (listener != null) listener.onIabPurchaseFinished(r, null);
但是我的代码中有“ return”语句,但仍然给出相同的错误。
错误代码:
act.startIntentSenderForResult(pendingIntent.getIntentSender(),
requestCode, new Intent(),
Integer.valueOf(0), Integer.valueOf(0),
Integer.valueOf(0));
完整的launchPurchaseFlow方法:
public void launchPurchaseFlow(Activity act, String sku, String itemType, int requestCode,
OnIabPurchaseFinishedListener listener, String extraData) {
checkNotDisposed();
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.");
flagEndAsync();
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));
flagEndAsync();
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();
flagEndAsync();
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();
flagEndAsync();
result = new IabResult(IABHELPER_REMOTE_EXCEPTION, "Remote exception while starting purchase flow");
if (listener != null) listener.onIabPurchaseFinished(result, null);
}
}
最佳答案
检查pendingIntent
是否为空:
PendingIntent pendingIntent = buyIntentBundle.getParcelable(RESPONSE_BUY_INTENT);
if (pendingIntent == null)
Log.E(TAG, "pendingIntent is null");
