paypal android SDK与我的应用程序集成不起作用

Question

您好我正在尝试将Paypal AndroidSDK与我的Android应用程序集成.我按照paypal集成文档,并尝试按照说明进行集成.但是当我按下购买按钮屏幕时,导航到下面显示的paypal屏幕.

但是当使用PaymentConfirmation结果完成付款流程后,当我按下购买按钮而不是RESULT_OK时,onActivityResult回调将立即返回结果为0(RESULT_CANCELED).

以下是我的代码段.

  public void initPaymentService() {
    try {
        Intent intent = new Intent(this, PayPalService.class);

        intent.putExtra(PaymentActivity.EXTRA_PAYPAL_ENVIRONMENT, CONFIG_ENVIRONMENT);
        intent.putExtra(PaymentActivity.EXTRA_CLIENT_ID, CONFIG_CLIENT_ID);

    //  intent.putExtra(PaymentActivity.EXTRA_RECEIVER_EMAIL, CONFIG_RECEIVER_EMAIL);

        startService(intent);
    } catch (Exception e) {
    }
}

public void onBuyPressed(String amount) {
    PayPalPayment thingToBuy = new PayPalPayment(new BigDecimal("1.75"), "USD", "hipster jeans");

    Intent intent = new Intent(this, PaymentActivity.class);

    intent.putExtra(PaymentActivity.EXTRA_PAYPAL_ENVIRONMENT, CONFIG_ENVIRONMENT);
    intent.putExtra(PaymentActivity.EXTRA_CLIENT_ID, CONFIG_CLIENT_ID);
    intent.putExtra(PaymentActivity.EXTRA_RECEIVER_EMAIL, CONFIG_RECEIVER_EMAIL);

    // It's important to repeat the clientId here so that the SDK has it if Android restarts your 
    // app midway through the payment UI flow.
    intent.putExtra(PaymentActivity.EXTRA_CLIENT_ID, "AL7neK4uQk1xTc-YsELHpTAvdkjscvGNJDGHhashc8BLL8nkaTesRWkHOczSmqMkKT"); // **Clientid** from **developer.paypal.com**
    intent.putExtra(PaymentActivity.EXTRA_PAYER_ID, "testpaypal@gmail.com");

    intent.putExtra(PaymentActivity.EXTRA_PAYMENT, thingToBuy);

    startActivityForResult(intent, 0);
}

@Override
protected void onActivityResult (int requestCode, int resultCode, Intent data) {

     if (resultCode == Activity.RESULT_OK) {
        PaymentConfirmation confirm = data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
        if (confirm != null) {
            try {
                Log.i("PaypalTestActivity", confirm.toJSONObject().toString(4));

                // TODO: send 'confirm' to your server for verification.
                // see https://developer.paypal.com/webapps/developer/docs/integration/mobile/verify-mobile-payment/
                // for more details.

            } catch (JSONException e) {
                Log.e("PaypalTestActivity", "an extremely unlikely failure occurred: ", e);
            }
        }
    }
    else if (resultCode == Activity.RESULT_CANCELED) {
        Log.i("PaypalTestActivity", "The user canceled the Transaction.");
    }
    else if (resultCode == PaymentActivity.RESULT_PAYMENT_INVALID) {
        Log.i("PaypalTestActivity", "An invalid payment was submitted. Please see the docs.");
    }
}

如果我的Activity,initPaymentService()方法调用来自onCreate.我的按钮位于片段中,活动继承自v4支持库中的FragmentActivity.

请让我知道我做错了什么,为什么立即调用onActivityResult而不是通过确认信息完成付款流程.

如果您知道我的问题的解决方案,请告诉我.任何帮助将不胜感激.

最后我找到了解决方案.

PayPal androidSDK集成不起作用如果Current(我放置Buy按钮)活动的android:launchMode ="singleInstance".当我将launchMode移除到该活动时,其工作正常.
