Link S3 Bucket with Dynamodb android?

Question

I want to do the following(Android App) :-

1. Upload UserProfile photo to S3 bucket.
2. Connect S3 bucket to Dynamodb(userprofile.png link next to user id in Table).

I have read the Amazon documentation which is quie confusing ?

Can anyone give the sample code of uploading image to AWS S3 and get the image file's S3 bucket url and save it to dynamodb all at once?

Answer 1

There might be two possibilities of doing this:

First possibility:(Done completely internal to app)

1. In the android app upload the image to the s3 bucket using the Java sdk (refer : https://github.com/awsdocs/aws-doc-sdk-examples/tree/master/java/example_code/s3/src/main/java )
2. Once the image is uploaded add the url to the Dynamodb table

Second possibility:

1. Upload the image to S3
2. Enable and Configure Event Notifications for S3 Bucket and send to SNS topic
3. Subscribe a lambda function to SNS topic
4. Execute a lambda function to add s3 object url to dynamodb table
