Cleaning up your AWS account after using Amplify

The Amplify tools create a lot of resources in your AWS account. When you stop using Amplify, you'll want some way to remove it all. This document discusses some various strategies to cleanup your AWS account when offboarding Amplify.

The commands below will call the AWS CLI (and not the Amplify CLI.)

Removing Apps

Fortunately, most of the Amplify stack if managed through CloudFormation under the hood. This means that you can cleanup most of the outputs just by deleting the Amplify "app."

A collection of some seminal pieces of customer feedback.

Regarding production-readiness:

1. Cognito Feedback
2. Amplify should be built for Amazon first, then developers!
3. Frank Discussion on Amplify Quality, Reliability
4. "I don't want more Amplify platforms, I want them to fix the existing issues"
5. AWS Cognito & Amplify Auth - Bad, Bugged, Baffling

Using the V2 AWS Java SDK from Android

The V2 AWS Java SDK can be used from Android, with a few caveats.

Note: currently, this is limited to API 26 and higher (60% of production devices, as of 06JUL2020.)

Other Note: this document is not production guidance for application builders. These are some of my personal notes after some study and expirementation.

Hitting AWS AppSync from Apollo Android 2.2.0

This document describes howto setup an AppSync endpoint, and talk to it using the Apollo Android 2.2.0 client.

Deploy an AppSync endpoint

In the AWS AppSync console, I created a new endpoint here, by selecting the "Event app" under "Start from a sample project."

The goal of this exercise is to show how a simple functional interface could be used to return a Result value type. The Result value type can contain an error (getError()), or a value (getValue()), depending. A user is able to figure this out by inspecting the Result.Type, and exhausting the potential values of this enum via a switch.

Consuming a multi-values result type:

package com.amplifyframework.ioscbs;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
