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）。然后它开始转移。这是日志：

然后没有更多的日志，进度永远停止！
使用[sdk源代码]（https://github.com/aws/aws-sdk-android/）下载并调试后。我无限地在UrlHttpClient.java中找到了程序块：
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!
}
}
BTW我使用的sdk版本是2.1.17。 有朋友可以帮忙吗？感谢。
答案 0 :(得分：0)
几种可能性： - 监听器未注册。示例应用程序在上载活动暂停时取消注册侦听器，以防止内存泄漏。我没有代码，也不知道你的用例。但请确保听众仍在注册。 - 早期的SDK版本存在让侦听器保持活跃的问题。请使用最新版本v2.2.14（如果您遇到NPE，请使用2.2.13）。
