Amazon S3 is a cloud storage service where you can store any number of objects from anywhere on the internet. We’ll use S3 in this tutorial to store an image uploaded from our Android app and then download and display the image in our app.
Cognito is a sign-up, sign-in, and access control service. We’ll use it in this tutorial to control access to our S3 images. We’ll only allow signed-in users to upload images to our S3 bucket while both signed-in and guest users will be able to download images.
You can add sign-in using the Google API but there is an alternative. You can use Amazons’ Cognito, “Simple and Secure User Sign-Up, Sign-In, and Access Control. Amazon Cognito lets you add user sign-up, sign-in, and access control to your web and mobile apps quickly and easily. Amazon Cognito scales to millions of users and supports sign-in with social identity providers, such as Facebook, Google, and Amazon, and enterprise identity providers via SAML 2.0.”
We’ve created a series of quick and easy tutorials showing you how you can add sign-up and sign-in to your Android up using Cognito. Here’s the first of the series, check it out:
