Android 将多个文件上传到 AWS S3 失败

Question

我从https://github.com/awslabs/aws-sdk-android-samples 下载了 S3TransferUtilitySample。启动 S3TransferUtility |管理上传 |上传图片 选择一个图像（我的测试图像是一个大约 23M 的文件）。然后它开始传输。这是日志：

然后没有更多的日志，进度永远停止！

在我下载并使用 [sdk 源代码] (https://github.com/aws/aws-sdk-android/) 进行调试之后。我在UrlHttpClient.java中找到了无限的程序块：

private void write(InputStream is, OutputStream os) throws IOException {
    byte[] buf = new byte[1024 * 8];
    int len;
    while ((len = is.read(buf)) != -1) {
        os.write(buf, 0, len); //block at this line!
    }
}

顺便说一句，我使用的 sdk 版本是 2.1.17。 有朋友可以帮忙吗？谢谢。

Answer 1

几种可能性： - 侦听器未注册。示例应用在上传活动暂停时取消注册监听器，以防止内存泄漏。我没有代码，也不知道您的用例。但请确保侦听器仍处于注册状态。 - 较早的 SDK 版本存在保持侦听器活动的问题。请使用最新版本 v2.2.14（如果遇到 NPE，请使用 2.2.13）。
