Upload an image from Android to Amazon S3?

Question

I need to upload a bitmap to Amazon S3. I have never used S3, and the docs are proving less than helpful as I can\'t see anything to cover this specific requirement. Unfortunate

Answer 1

We can directly use "Amazone s3" bucket for storing any type of file on server, and we did not need to send any of file to Api server it will reduce the request time.

Gradle File :-

 compile 'com.amazonaws:aws-android-sdk-core:2.2.+'
    compile 'com.amazonaws:aws-android-sdk-s3:2.2.+'
    compile 'com.amazonaws:aws-android-sdk-ddb:2.2.+'

Manifest File :-

FileUploader Function in any Class :-

 private void setUPAmazon() {
 //we Need Identity Pool ID  like :- "us-east-1:f224****************8"
        CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(getActivity(),
                "us-east-1:f224****************8", Regions.US_EAST_1);
        AmazonS3 s3 = new AmazonS3Client(credentialsProvider);
        final TransferUtility transferUtility = new TransferUtility(s3, getActivity());
        final File file = new File(mCameraUri.getPath());
        final TransferObserver observer = transferUtility.upload(GeneralValues.AMAZON_BUCKET, file.getName(), file, CannedAccessControlList.PublicRead);
        observer.setTransferListener(new TransferListener() {
            @Override
            public void onStateChanged(int id, TransferState state) {
                Log.e("onStateChanged", id + state.name());
                if (state == TransferState.COMPLETED) {
                    String url = "https://"+GeneralValues.AMAZON_BUCKET+".s3.amazonaws.com/" + observer.getKey();
                    Log.e("URL :,", url);
//we just need to share this File url with Api service request.  
                }
            }

            @Override
            public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {
            }

            @Override
            public void onError(int id, Exception ex) {
                Toast.makeText(getActivity(), "Unable to Upload", Toast.LENGTH_SHORT).show();
                ex.printStackTrace();
            }
        });
    }
