Android Amazon S3文件上传不起作用

智者不为愚者谋，勇者不为怯者死。这篇文章主要讲述Android Amazon S3文件上传不起作用相关的知识，希望能为你提供帮助。
我正在尝试将sd卡上的文件上传到我的amazon s3存储桶。这是班级：

public class FileUploadDownload { Context context; boolean transferComplete = false; float transferPercentage = 0; public FileUploadDownload(Context context) { this.context = context; }public void uploadFile(File file , String nameOfFile) { CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider( context, "cognito_identity_pool_id", // Identity Pool ID Regions.EU_WEST_1 // Region ); AmazonS3 s3 = new AmazonS3Client(credentialsProvider); TransferUtility transferUtility = new TransferUtility(s3, context); TransferObserver observer = transferUtility.upload( "s3_bucket",/* The bucket to upload to */ nameOfFile,/* The key for the uploaded object */ file/* The file where the data to upload exists */ ); observer.setTransferListener(new TransferListener() { @Override public void onStateChanged(int id, TransferState state) { Toast.makeText(context,"State changed to : "+state.toString(),Toast.LENGTH_SHORT).show(); }@Override public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {//transferPercentage = (float)bytesCurrent/(float)bytesTotal; if(bytesCurrent == bytesTotal) { //transferComplete = true; Toast.makeText(context,"Upload completed!",Toast.LENGTH_SHORT).show(); } }@Override public void onError(int id, Exception ex) { Toast.makeText(context,"Upload Unsuccessful due to `"+ex.toString(),Toast.LENGTH_LONG).show(); } }); } }

这是我在Activity的OnCreate（）方法中实现的代码片段：

File sdCard = Environment.getExternalStorageDirectory(); File dir = new File (sdCard.getAbsolutePath() + "/EpisodeRecorder/User1/Episode1/User1e1p1.jpg"); FileUploadDownload fud = new FileUploadDownload(this); fud.uploadFile(dir,"trialFileUpload.jpg");

这是清单的顶部：

【Android Amazon S3文件上传不起作用】

< uses-permission android:name="android.permission.CAMERA" /> < uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> < uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> < uses-permission android:name="android.permission.RECORD_AUDIO" /> < uses-permission android:name="android.permission.INTERNET" /> < uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> < application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/CustomActionBarTheme" > < service android:name="com.amazonaws.mobileconnectors.s3.transferutility.TransferService" android:enabled="true" /> .....

我通过toasts显示所有调试消息。最初它显示“IN PROGRESS”，稍后，它显示“FAILED”错误消息“java.lang.IllegalStateException”在DEBUG LOG中它说：

10-12 21:01:01.1381252-14041/? E/CloudSettingsConnection﹕ Connection failed : SERVER_ERROR

我无法弄清楚发生了什么。如果你能指出错误那就太棒了。或者，如果您能够确定错误是在Amazon s3 / cognito / IAM设置还是代码中，我会很高兴。谢谢！
这是要求的整个堆栈跟踪：

答案我不确定这对你有用，但我遇到了同样的问题，我发现该文件的名称最后有“.png”，所以我删除它并且它有效，在删除之前我检查currentBytes，在它给我FAILED状态之前，currentBytes的数量等于totalBytes但是我的状态仍为FAILED，所以
