使用 Android Studio 实现 Paypal SDK - 无法从应用程序登录

如何解决使用 Android Studio 实现 Paypal SDK - 无法从应用程序登录

调用 PaypalService.class 的活动：

\

 //PAYPAL SDK VARIABLES
    public static final int PAYPAL_REQUEST_CODE = 7171;
    private static PayPalConfiguration config = new PayPalConfiguration()
            .environment(PayPalConfiguration.ENVIRONMENT_SANDBOX)
            .clientId(Config.PAYPAL_CLIENT_ID);

Config.java 位于不同的文件夹中。它能够连接到应用程序（Client_id 是一个有效的密钥）

 Intent payPalIntent = new Intent(this,PayPalService.class);
        payPalIntent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION,config);
        startService(payPalIntent);


        payment = (Button) findViewById(R.id.payment);
        payment.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                processPayment();
            }


        });

    }//END OF ON CREATE

    @Override
    protected void onDestroy() {
        stopService(new Intent(this,PayPalService.class));
        super.onDestroy();
    }

    @Override
    protected void onActivityResult(int requestCode,int resultCode,@Nullable Intent data) {
        super.onActivityResult(requestCode,resultCode,data);
        if (requestCode == PAYPAL_REQUEST_CODE) {
            if (resultCode == RESULT_OK) {
                PaymentConfirmation confirmation = data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
                if (confirmation != null) {
                    try {
                        String paymentDetails = confirmation.toJSONObject().toString(4);

                        startActivity(new Intent(this,GetTheBike.class)
                                .putExtra("PaymentDetails",paymentDetails)
                                .putExtra("PaymentAmount",amount_to_pay)
                        );


                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            } else if (resultCode == Activity.RESULT_CANCELED) {
                Toast.makeText(this,"Cancel",Toast.LENGTH_SHORT).show();
            } else if (resultCode == PaymentActivity.RESULT_EXTRAS_INVALID)
                Toast.makeText(this,"Invalid",Toast.LENGTH_LONG).show();
        }
    }

    private void processPayment() {
        PayPalPayment payPalPayment = new PayPalPayment(new BigDecimal(amount_to_pay),"USD","Pay for parking",PayPalPayment.PAYMENT_INTENT_SALE);
        Intent intent = new Intent(this,PaymentActivity.class);
        intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION,config);
        intent.putExtra(PaymentActivity.EXTRA_PAYMENT,payPalPayment);
        startActivityForResult(intent,PAYPAL_REQUEST_CODE);


    }
}

我使用有效的客户沙箱帐户登录（在 sandbox.paypal.com 上测试登录），这是登录后出现的错误

package com.example.becoapk21.Config;

public class Config {
    public static final String PAYPAL_CLIENT_ID="CLIENT_ID";
}

注意：paypal 沙盒帐户位于 IL 。我也尝试过创建美国帐户，但没有用

解决方法

这似乎是一个已弃用的 Android SDK，适用于现已终止的服务。

请参阅新的 Native Checkout SDK。
