如何使用Google Play Developer API Client Library for Java将扩展文件上传到草稿Apk？

<dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-androidpublisher</artifactId>
    <version>v3-rev20220117-1.32.1</version>
</dependency>

import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.services.androidpublisher.AndroidPublisher;
import com.google.api.services.androidpublisher.AndroidPublisherScopes;

// 加载服务帐户密钥文件
GoogleCredential credential = GoogleCredential.fromStream(new FileInputStream("path/to/service-account-key.json"))
        .createScoped(AndroidPublisherScopes.all());

// 创建AndroidPublisher对象
AndroidPublisher androidPublisher = new AndroidPublisher.Builder(
        GoogleNetHttpTransport.newTrustedTransport(),
        JacksonFactory.getDefaultInstance(),
        credential)
        .setApplicationName("Your Application Name")
        .build();

import com.google.api.services.androidpublisher.model.Bundle;
import com.google.api.services.androidpublisher.model.BundleExpansionFile;

// 创建BundleExpansionFile对象
BundleExpansionFile expansionFile = new BundleExpansionFile();
expansionFile.setReferencesVersion(1); // 设置引用版本号
expansionFile.setFile("path/to/your/extension-file"); // 设置扩展文件路径

// 创建Bundle对象
Bundle bundle = new Bundle();
bundle.setVersionCode(1); // 设置版本号
bundle.setExpansionFiles(Arrays.asList(expansionFile)); // 设置扩展文件列表

// 上传扩展文件到草稿APK
AndroidPublisher.Edits.Bundles.Upload uploadRequest = androidPublisher.edits().bundles()
        .upload("your-package-name", editId, bundle);
Bundle uploadedBundle = uploadRequest.execute();
