我想将paypal集成到我的应用中。在我看到这个时,我快到了那里:https://developer.paypal.com/webapps/developer/support/faq#non-US-dev Paypal不允许非美国开发人员使用REST API。所以我留下的选择是经典的api。这就是问题所在。我不知道如何使用它们。
我打算使用NVP api。我不知道怎么做但下面是我计划做的方式的流程图。我需要在checkout.java上设置项目编号,描述,价格等,这将发送到www.domain.com/setsessions.php
我不确定它是否会起作用。但即便如此,我也不知道新的'意图'如何检测用户是否已成功付款,付款失败或取消付款。
我需要帮助。这真是令人沮丧......已经尝试将paypal整合近2周。感觉非常无益......
这甚至可以吗?还是有更好的方法? 我的要求是设置发票编号,项目编号,描述,价格,位置,这些都是应用程序所需的。

MainActivity.java
public class PizzaMain extends Activity implements OnClickListener {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
PayPal ppObj = PayPal.initWithAppID(this.getBaseContext(), "APP-80W284485P519543T", PayPal.ENV_NONE);
CheckoutButton launchPayPalButton = ppObj.getCheckoutButton(this, PayPal.BUTTON_152x33, CheckoutButton.TEXT_PAY);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.CENTER_HORIZONTAL);
launchPayPalButton.setLayoutParams(params);
launchPayPalButton.setOnClickListener(this);
((RelativeLayout) findViewById(R.id.mRlayout1)).addView(launchPayPalButton);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
PayPalPayment newPayment = new PayPalPayment();
char val[] = { '5', '0' };
BigDecimal obj_0 = new BigDecimal(val);
newPayment.setSubtotal(obj_0);
newPayment.setCurrencyType("USD");
newPayment.setRecipient("my@email.com");
newPayment.setMerchantName("My Company");
Intent paypalIntent = PayPal.getInstance().checkout(newPayment, this);
this.startActivityForResult(paypalIntent, 1);
}
@SuppressWarnings("unused")
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (resultCode) {
case Activity.RESULT_OK:
// The payment succeeded
String payKey = data.getStringExtra(PayPalActivity.EXTRA_PAY_KEY);
// Tell the user their payment succeeded
break;
case Activity.RESULT_CANCELED:
// The payment was canceled
// Tell the user their payment was canceled
break;
case PayPalActivity.RESULT_FAILURE:
// The payment failed -- we get the error from the EXTRA_ERROR_ID
// and EXTRA_ERROR_MESSAGE
String errorID = data.getStringExtra(PayPalActivity.EXTRA_ERROR_ID);
String errorMessage = data.getStringExtra(PayPalActivity.EXTRA_ERROR_MESSAGE);
// Tell the user their payment was failed.
break;
}
}
}
并在AndroidManifest.xml文件中提供以下权限。
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
将Activity添加到AndroidManifest.xml文件中。
<activity
android:name="com.paypal.android.MEP.PayPalActivity"
android:configChanges="keyboardHidden|orientation"
android:theme="@android:style/Theme.Translucent.NoTitleBar" />
将PayPal_MPL.jar Jar文件作为参考库添加到您的应用程序中
