最新發現Paypal的官方SDK已經不再維護了，所以需要把項目的支付做一下升級。

根據文檔來看Paypal支付的集成相比以前簡單了許多，下面我們講一下集成步驟：
1：在 build.gradle 中添加以下內容
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：從服務器獲取Token
根據後臺提供的 url 獲取到Token 後臺 集成鏈接
4：初始化
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_paypal);
//初始化並添加監聽
try {
mBraintreeFragment = BraintreeFragment.newInstance(this, mAuthorization);
mBraintreeFragment.addListener(new ConfigurationListener() {
@Override
public void onConfigurationFetched(Configuration configuration) {
}
});
// 支付完成監聽
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();
}
}
});
// 取消監聽
mBraintreeFragment.addListener(new BraintreeCancelListener() {
@Override
public void onCancel(int requestCode) {
}
});
// 錯誤監聽
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：調起支付
yourButton.setOnClickListener(new View.OnClickListener(){
@Override public void onClick (View view){
setupBraintreeAndStartExpressCheckout();
}
})
public void setupBraintreeAndStartExpressCheckout() {
PayPalRequest request = new PayPalRequest(“價格”)
.currencyCode("貨幣符號")
.intent(PayPalRequest.INTENT_SALE);
PayPal.requestOneTimePayment(mBraintreeFragment, request);
}
這裏注意三種Intent的意思 INTENT_SALE 表示立即到賬。
5：付款成功後訪問服務器驗證
private void postNonceToServer(String nonce) {
final Map<String, String> dataMap = new HashMap<>();
dataMap.put("nonce", nonce);
dataMap.put("amount", price);
}
驗證的接口由後臺給這裏邏輯由後臺處理，這裏返回成功，說明支付並驗證成功。
大家測試的時候一定要用美國地址的paypal進行測試哈。
