如何在 android 中关闭或释放 AWSAppSyncClient

Question

我正在使用 AWSAppSyncClient 服务，这是我在应用程序中使用的单一对象

client = AWSAppSyncClient.builder()
        .context(context)
        .awsConfiguration(awsConfiguration)
        .credentialsProvider(
            CognitoCachingCredentialsProvider(
                context,
                ...
            )
        ).build()

而且我在使用 StrictMode 时发现内存泄漏，这是已记录问题的完整堆栈跟踪：

E/StrictMode: A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks.

我必须使用最新更新的appsync版本，我使用的是2.6.+版本，所以我现在使用的是versoin 2.9.0，内存泄漏消失了。
