添加以下依赖项

compile "com.google.apis:google-api-services-androidpublisher:v3-rev103-1.25.0"
compile "com.google.auth:google-auth-library-oauth2-http:0.17.1"

然后从Google Cloud Console 此处启用Google Developer Play Api库

Then enable Google Developer Play Api library from Google Cloud Console here

使用凭据创建具有角色Pub/Sub Admin的服务帐户密钥并保存json文件

In credentials Create service account key with role Pub/Sub Admin and save json file

在Google开发者控制台中此处. 在Settings >> Developer Account >> API Access中，链接您的应用.

然后在代码中执行以下操作以获取订阅信息.

Then in code do following to get subscription info.

GoogleCredentials credentials = GoogleCredentials.fromStream(new FileInputStream("<service-account-key-file>.json")).createScoped(AndroidPublisherScopes.ANDROIDPUBLISHER);

AndroidPublisher pub = new AndroidPublisher.Builder(
        GoogleNetHttpTransport.newTrustedTransport(),
        JacksonFactory.getDefaultInstance(),
        new HttpCredentialsAdapter(credentials)
).setApplicationName("<app-name>").build();
SubscriptionPurchase purchase = pub.purchases().subscriptions().get(
        "<app-package>",
        "<subscription-id>",
        "<purchase-token>"
).execute();
println(purchase);
