Question

我正在创建测试用途的paypal应用程序。我已经创建了测试paypal帐户，并在我的活动中按下了我的按钮点击了下面的代码。但没有任何东西可以展示并获得例外：

09-26 13:52:51.908: E/NetworkHandler(540): postXML caught exception doing I/O, mobileclient.sandbox.paypal.com

代码：

float ammount = Float.parseFloat(_details.get(_G_no)
            .get_product_price());
     PayPalPayment newPayment = new PayPalPayment();
     newPayment.setSubtotal(BigDecimal.valueOf(ammount));
     newPayment.setCurrencyType("USD");
     newPayment.setRecipient("account@gmail.com");
     newPayment.setMerchantName("Merchant");
    PayPal pp = PayPal.getInstance();
     if(pp==null)
     pp = PayPal.initWithAppID(this, id, PayPal.ENV_SANDBOX);

    final Intent paypalIntent = pp.checkout(newPayment, this);
        this.startActivityForResult(paypalIntent, 1);

我的应用中有互联网许可。请帮帮我。

我不知道，这是否正确。但我通过在您的代码之前创建互联网连接找到了解决方案，并与Vikalp patel联系以识别Have you found the solution of NetworkHandler Error。

            PayPal pp = PayPal.getInstance();

            // If the library is already initialized, then we don't need to initialize it again.
            if(pp == null)

                pp.setDynamicAmountCalculationEnabled(false);
                // --
            }

            if (pp.isLibraryInitialized())

            else 
            {

        protected void onPostExecute(String result)
        {
            initializationStatus ( result ) ;

    }

    asynctaskToInitLibrary object = new asynctaskToInitLibrary() ;
    object.execute("") ;
