我尝试使用Amazon Mobile SDK Android下载文件。我创建了我的存储桶，在我设置的权限中，每个人都可以写和读。在amazon Cognito中，我将所有内容都保留为默认值。
尝试从我的存储桶下载任何文件时出现此错误...

答案 0 :(得分：0)
你必须在gradle中包含以下库
compile 'com.amazonaws:aws-android-sdk-core:2.2.13'
compile 'com.amazonaws:aws-android-sdk-s3:2.2.13'
在创建存储桶并使用该信息下载或上传文件时获取池ID和存储桶名称。如需更多使用链接https://www.numetriclabz.com/integrate-amazon-s3-to-android-tutorial/
