Amplify and Cognito

AUTHENTICATION

• Amplify Auth category provides an interface for authenticating a user. Behind the scenes, it provides the necessary authorization to the other Amplify categories.
• Comes with default, built-in support for Amazon Cognito User Pool and Identity Pool.
• The Amplify CLI helps you to create and configure the auth category with an authentication provider.
• Setup
  • Prerequisites - Android application targeting at least Android SDK API level 16 with Amplify libraries integrated
  • Configure Auth Category with the command: amplify add auth
  • Enter the following when prompted: ? Do you want to use the default authentication and security configuration? Default configuration ? How do you want users to be able to sign in? Username ? Do you want to configure advanced settings? No, I am done.
  • To push your changes to the cloud, execute the command: amplify push
  • Install Amplify Libraries: dependencies { implementation ‘com.amplifyframework:aws-auth-cognito:1.17.1’ }
  • Initialize Amplify Auth - Add the Auth plugin before calling Amplify.configure. Update the code you added in Prerequisites: // Add this line, to include the Auth plugin. Amplify.addPlugin(new AWSCognitoAuthPlugin()); Amplify.configure(getApplicationContext());
  • Check the current auth session: Amplify.Auth.fetchAuthSession( result -> Log.i(“AmplifyQuickstart”, result.toString()), error -> Log.e(“AmplifyQuickstart”, error.toString()) );
