#Realtime Storage SDK for React-Native Android

Realtime Cloud Storage is a fully managed NoSQL database service based on Amazon DynamoDB that provides fast and predictable performance with seamless scalability.

If you are a developer, you can use Realtime Cloud Storage to create database tables that can store and retrieve any amount of data, and serve any level of request traffic.

##Installation

You are ready to go.

Example

This example uses the Realtime Cloud Storage React Native Android SDK to save and retrieve todo lists from the cloud. It can be also used with the other Realtime Todo samples, including the on-line example.

Data will be synced in real-time between devices and browsers.
