我已将我的应用上传到Google Play,并在应用中添加了IAP.我可以成功检索我的应用程序的IAP列表及其价格,但当我实际尝试购买时,我的设备会出现以下错误(没有错误)

This version of the application is not configured for billing through
Google Play. Check the help centre for more information.

以下是检索IAP可用并进行购买的代码

ArrayList skuList = new ArrayList();
        skuList.add("MysqLmanager_pro");

        Bundle querySkus = new Bundle();
        querySkus.putStringArrayList("ITEM_ID_LIST",skuList);
        try
        {
            Bundle skuDetail = mService.getSkuDetails(3,getPackageName(),"inapp",querySkus);
            Log.d("Billing","Response Received");

            int billingResponse = skuDetail.getInt("RESPONSE_CODE");
            if (billingResponse == 0)
            {
                //Get list of IAP's to purcase - NOT NEEDED
                ArrayList responseList = skuDetail.getStringArrayList("DETAILS_LIST");

                Log.d("Billing","Response");

                Bundle buyIntentBundle = mService.getBuyIntent(3,"MysqLmanager_pro","");

                PendingIntent pendingIntent = buyIntentBundle.getParcelable("BUY_INTENT");

                startIntentSenderForResult(pendingIntent.getIntentSender(),Defines.IntentRequestCodes.IAP_PURCHASE_REQUEST,new Intent(),Integer.valueOf(0),Integer.valueOf(0));
                /*for (String thisResponse : responseList)
                {
                    JSONObject object = new JSONObject(thisResponse);
                    String sku = object.getString("productid");
                    String price = object.getString("price");
                }*/
            }

        }
        catch (Exception ex)
        {
            Log.e("Billing",ex.toString());
        }

我的onCreate包含以下内容

mServiceConn = new ServiceConnection() {

            @Override
            public void onServiceDisconnected(ComponentName name) {
                mService = null;
            }

            @Override
            public void onServiceConnected(ComponentName name,IBinder service) {
                mService = IInAppBillingService.Stub.asInterface(service);
            }
        };

        bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"),mServiceConn,Context.BIND_AUTO_CREATE);
