在 Android 中集成 paypal 时出错？

Question

我正在尝试将 paypal 集成到我的 Android 应用程序中。我正在遵循这种方法 http://sunil-android.blogspot.in/2013/10/paypal-android-sdk-with-multiple-in-app.html

我在我的应用中添加了 Paypal Android SDK 库。

但是它给我一个错误，很多像PaymentActivity.ENVIRONMENT_LIVE;这样的方法都无法解决。

感谢您的帮助

如果您使用的是安卓工作室。然后只需将 paypal sdk 添加到您的应用级 build.gradle 文件中。

compile 'com.paypal.sdk:paypal-android-sdk:2.14.2'

现在您可以使用以下代码接受付款。请记住，您还需要您的贝宝客户端 ID。您可以通过在 developer.paypal.com 上创建一个应用来获取它

private void getPayment() {
    //Getting the amount from editText
    paymentAmount = editTextAmount.getText().toString();

    //Creating a paypalpayment 
    PayPalPayment payment = new PayPalPayment(new BigDecimal(String.valueOf(paymentAmount)), "USD", "Simplified Coding Fee",
            PayPalPayment.PAYMENT_INTENT_SALE);

    //Creating Paypal Payment activity intent 
    Intent intent = new Intent(this, PaymentActivity.class);

    //putting the paypal configuration to the intent 
    intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, config);

    //Puting paypal payment to the intent 
    intent.putExtra(PaymentActivity.EXTRA_PAYMENT, payment);

    //Starting the intent activity for result
    //the request code will be used on the method onActivityResult 
    startActivityForResult(intent, PAYPAL_REQUEST_CODE);
}

活动结果代码将是

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    //If the result is from paypal 
    if (requestCode == PAYPAL_REQUEST_CODE) {

        //If the result is OK i.e. user has not canceled the payment 
        if (resultCode == Activity.RESULT_OK) {
            //Getting the payment confirmation 
            PaymentConfirmation confirm = data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);

            //if confirmation is not null 
            if (confirm != null) {
                try {
                    //Getting the payment details 
                    String paymentDetails = confirm.toJSONObject().toString(4);
                    Log.i("paymentExample", paymentDetails);

                    //Starting a new activity for the payment details and also putting the payment details with intent 
                    startActivity(new Intent(this, ConfirmationActivity.class)
                            .putExtra("PaymentDetails", paymentDetails)
                            .putExtra("PaymentAmount", paymentAmount));

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

那篇博文指的是 SDK 的 1.x 版本，但您很可能使用的是 2.x。我建议您使用我们的latest GitHub docs 获取最新的集成信息。

检查您导入的库 只需导入 Ravi tamanda android hive 演示中给出的库 http://www.androidhive.info/2015/02/android-integrating-paypal-using-php-mysql-part-2

并在您的 Paypal 帐户中导入 jniLibs 库
