Android集成Paypal支付Braintree

最新发现Paypal的官方SDK已经不再维护了，所以需要把项目的支付做一下升级。

根据文档来看Paypal支付的集成相比以前简单了许多，下面我们讲一下集成步骤：

1：在 build.gradle 中添加以下内容

    compile 'com.braintreepayments.api:braintree:2.+'

2：在你的 AndroidManifest.xml  中添加

<activity android:name="com.braintreepayments.api.BraintreeBrowserSwitchActivity"
    android:launchMode="singleTask">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="${applicationId}.braintree" />
    </intent-filter>
</activity>

3：从服务器获取Token

     根据后台提供的 url 获取到Token  后台 集成链接

4：初始化

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_paypal);  
//初始化并添加监听
 try {
     mBraintreeFragment = BraintreeFragment.newInstance(this, mAuthorization);


    mBraintreeFragment.addListener(new ConfigurationListener() {
        @Override
        public void onConfigurationFetched(Configuration configuration) {

        }
    });
    // 支付完成监听
    mBraintreeFragment.addListener(new PaymentMethodNonceCreatedListener() {
        @Override
        public void onPaymentMethodNonceCreated(PaymentMethodNonce paymentMethodNonce) {
            // Send nonce to server
            String nonce = paymentMethodNonce.getNonce();
            postNonceToServer(nonce);
            if (paymentMethodNonce instanceof PayPalAccountNonce) {
                PayPalAccountNonce payPalAccountNonce = (PayPalAccountNonce) paymentMethodNonce;
                // Access additional information
                String email = payPalAccountNonce.getEmail();
                String firstName = payPalAccountNonce.getFirstName();
                String lastName = payPalAccountNonce.getLastName();
                String phone = payPalAccountNonce.getPhone();
                // See PostalAddress.java for details
                PostalAddress billingAddress = payPalAccountNonce.getBillingAddress();
                PostalAddress shippingAddress = payPalAccountNonce.getShippingAddress();
            }
        }
    });
    // 取消监听
    mBraintreeFragment.addListener(new BraintreeCancelListener() {
        @Override
        public void onCancel(int requestCode) {
         
        }
    });
    // 错误监听
    mBraintreeFragment.addListener(new BraintreeErrorListener() {
        @Override
        public void onError(Exception error) {
            if (error instanceof ErrorWithResponse) {
                ErrorWithResponse errorWithResponse = (ErrorWithResponse) error;
                BraintreeError cardErrors = errorWithResponse.errorFor("creditCard");
                if (cardErrors != null) {
                    // There is an issue with the credit card.
                    BraintreeError expirationMonthError = cardErrors.errorFor("expirationMonth");
                    if (expirationMonthError != null) {
                        // There is an issue with the expiration month.
                        LogUtils.e("paypal",expirationMonthError.getMessage());
                    }
                }
            }
        }
    });
    // mBraintreeFragment is ready to use!
} catch (InvalidArgumentException e) {
    // There was an issue with your authorization string.
}
}

5：调起支付

yourButton.setOnClickListener(new View.OnClickListener(){
    @Override public void onClick (View view){
    setupBraintreeAndStartExpressCheckout();
}
})

public void setupBraintreeAndStartExpressCheckout() {
    PayPalRequest request = new PayPalRequest(“价格”)
            .currencyCode("货币符号")
            .intent(PayPalRequest.INTENT_SALE);
    PayPal.requestOneTimePayment(mBraintreeFragment, request);
}

这里注意三种Intent的意思  INTENT_SALE 表示立即到账。

5：付款成功后访问服务器验证

private void postNonceToServer(String nonce) {
    final Map<String, String> dataMap = new HashMap<>();
    dataMap.put("nonce", nonce);
    dataMap.put("amount", price);
   
}

验证的接口由后台给这里逻辑由后台处理，这里返回成功，说明支付并验证成功。

大家测试的时候一定要用美国地址的paypal进行测试哈。
