Android Alipay Payment Integration: Video Tutorial54

Introduction

Alipay is one of the most popular mobile payment platforms in China. It allows users to make payments, transfer money, and perform other financial transactions. If you're developing an Android app that targets Chinese users, integrating Alipay is a must-have feature.

Prerequisites

Before you can start integrating Alipay, you'll need the following:
An Android device running Android 4.0 or higher
An Alipay account
The Alipay SDK

Step 1: Download the Alipay SDK

The Alipay SDK can be downloaded from the Alipay developer website. Once you've downloaded the SDK, extract it to a convenient location on your computer.

Step 2: Add the Alipay SDK to your Android project

To add the Alipay SDK to your Android project, open your project in Android Studio and import the SDK as a module. You can do this by clicking File > New > Import Module and selecting the Alipay SDK directory.

Step 3: Configure the Alipay SDK

Once you've imported the Alipay SDK, you'll need to configure it. To do this, open the file for your project's app module and add the following lines to the dependencies section:```
dependencies {
implementation ':alipay-sdk-core:3.7.43.20180907'
}
```

You'll also need to add the following lines to your file:```






```

Replace "your_app_id" with the app ID that you registered with Alipay when you created your account.

Step 4: Initialize the Alipay SDK

In your MainActivity, initialize the Alipay SDK as follows:```
public class MainActivity extends AppCompatActivity {
private AlipaySDK alipaySDK;
@Override
protected void onCreate(Bundle savedInstanceState) {
(savedInstanceState);
setContentView(.activity_main);
alipaySDK = new AlipaySDK(this);
}
}
```

Step 5: Create the Alipay payment request

To create the Alipay payment request, you'll need to use the Alipay SDK's PayTask class. The following code shows how to create a payment request for a product with a price of 100 yuan:```
PayTask alipayTask = new PayTask(this);
Map orderInfo = new HashMap();
("partner", "your_partner_id");
("seller_id", "your_seller_id");
("out_trade_no", "your_out_trade_no");
("subject", "your_subject");
("body", "your_body");
("total_fee", "100");
("notify_url", "your_notify_url");
String orderParam = (orderInfo);
String sign = (orderParam, "your_private_key");
```

Replace "your_partner_id", "your_seller_id", "your_out_trade_no", "your_subject", "your_body", "your_notify_url", and "your_private_key" with the appropriate values.

Step 6: Send the Alipay payment request

Once you've created the Alipay payment request, you can send it to Alipay by calling the PayTask's pay() method:```
Map result = (sign);
```

The result map will contain the status of the payment. If the payment was successful, the result map will contain the following key-value pairs:
resultStatus: "9000"
memo: "Success"

If the payment was not successful, the result map will contain the following key-value pairs:
resultStatus: "4000"
result: "Order paid failed"
memo: "The order was paid failed."

Conclusion

Integrating Alipay into your Android app is a great way to make it more accessible to Chinese users. By following the steps in this tutorial, you can easily add Alipay payment functionality to your app.
