AWS AppSync SDK for Android v2.9.0

New Features

• Support multiple authorization modes for a single AWS AppSync GraphQL endpoint.
• Introduced clientDatabasePrefix(String) that accepts a prefix that will be used in the construction of database name for caching query responses, offline mutations and subscriptions metadata. The usage of the prefix can be enabled by the flag useClientDatabasePrefix(true). When the prefix is used, the name of the database would look as follows:

Purpose of cache	No prefix	Valid prefix
Query responses	appsyncstore	<ClientDatabasePrefix>_appsyncstore
Offline Mutations	appsyncstore_mutation	<ClientDatabasePrefix>_appsyncstore_mutation
Subscriptions metadata for Delta Sync	appsync_deltasync_db	<ClientDatabasePrefix>_appsync_deltasync_db

• The ClientDatabasePrefix can be passed via awsconfiguration.json that is generated from the AWS AppSync Console and Amplify CLI.

     "AppSync": {
        "Default": {
          "ApiUrl": "https://xyz.appsync-api.us-east-2.amazonaws.com/graphql",
          "Region": "us-east-2",
          "AuthMode": "API_KEY",
          "ApiKey": "da2-xyz",
          "ClientDatabasePrefix": "MyAppSyncAPIName_API_KEY"
        }
      }
  

  The AWSAppSyncClient object can be constructed as follows:

      AWSAppSyncClient awsAppSyncClient = AWSAppSyncClient.builder()
                .awsConfiguration(awsConfiguration)
                .useClientDatabasePrefix(true)
                .build();

• Alternatively, the ClientDatabasePrefix can be passed via the AWSAppSyncClient.Builder.

     AWSAppSyncClient awsAppSyncClient = AWSAppSyncClient.builder()
                    .context(getApplicationContext())
                    .apiKey(new BasicAPIKeyAuthProvider("da2-apiKey"))
                    .serverUrl(serverUrl)
                    .region(region)
                    .useClientDatabasePrefix(true)
                    .clientDatabasePrefix("MyAppSyncAPIName_API_KEY")
                    .build();

Misc. Updates

• AWSAppSync now depends on AWSCore version 2.13.4 instead of 2.13.2.
