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

String      ACCESS_KEY="****************",
            SECRET_KEY="****************",
            MY_BUCKET="bucket_name",
            OBJECT_KEY="unique_id";              
  AWSCredentials credentials = new BasicAWSCredentials(ACCESS_KEY, SECRET_KEY);
                AmazonS3 s3 = new AmazonS3Client(credentials);
                java.security.Security.setProperty("networkaddress.cache.ttl" , "60");
                s3.setRegion(Region.getRegion(Regions.AP_SOUTHEAST_1));
                s3.setEndpoint("https://s3-ap-southeast-1.amazonaws.com/");
                List buckets=s3.listBuckets();
                for(Bucket bucket:buckets){
                    Log.e("Bucket ","Name "+bucket.getName()+" Owner "+bucket.getOwner()+ " Date " + bucket.getCreationDate());
                }
                Log.e("Size ", "" + s3.listBuckets().size());
                TransferUtility transferUtility = new TransferUtility(s3, getApplicationContext());
                UPLOADING_IMAGE=new File(Environment.getExternalStorageDirectory().getPath()+"/Screenshot.png");
                TransferObserver observer = transferUtility.upload(MY_BUCKET,OBJECT_KEY,UPLOADING_IMAGE);
                observer.setTransferListener(new TransferListener() {
                    @Override
                    public void onStateChanged(int id, TransferState state) {
                        // do something
                        progress.hide();
                        path.setText("ID "+id+"\nState "+state.name()+"\nImage ID "+OBJECT_KEY);

                    }

                    @Override
                    public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {
                        int percentage = (int) (bytesCurrent / bytesTotal * 100);
                        progress.setProgress(percentage);
                        //Display percentage transfered to user
                    }

                    @Override
                    public void onError(int id, Exception ex) {
                        // do something
                        Log.e("Error  ",""+ex );
                    }

                });
