如何在Android中使用Java将图像上传到Amazon s3存储桶？

Question

I am trying to upload an image I took from the camera to the s3 bucket.

CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
getApplicationContext(),
"us-west-2:xxxxxxxxxxxxx",
Regions.US_WEST_2
);

 AmazonS3Client s3Client = new AmazonS3Client(new AWSCredentials() {
        @Override
        public String getAWSAccessKeyId() {
            return "XXXXXXX";
        }

        @Override
        public String getAWSSecretKey() {
            return "XXXXXXX";
        }
    });


    TransferUtility transferUtility = new TransferUtility(s3Client,getApplicationContext());

transferUtility.upload(MY_BUCKET,file.getName(),file);

My pool is in us-west-2 but my bucket region is in Asia pacific Sydney.

Running the above code crashes and gives me the error below.

I have added permissons and services in the manifest file. How can I fix this and send an image to s3 bucket in Asia pacific sydney.

I have these permissions under manifest file -

   <uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="ANDROID.PERMISSION.ACCESS_NETWORK_STATE" />

正如错误明确指出的那样，您需要在清单中添加android.permission.ACCESS_NETWORK_STATE权限
