Use existing Amazon Location resources
You can also use Amplify Geo with your existing Amazon Location Service resources if you'd like, there's just some manual setup that you need to do.
Authorization permissions
To use your existing Amazon Location Service resources, i.e. maps and place indices, with Amplify Geo, you need to ensure your role has the right authorization permissions through Cognito. If you set up your Cognito resources in any way other than the Amplify CLI or Amplify Studio, the roles will need to be given permission to access the map and place indices.
Note: Here is a guide on Creating an Amazon Cognito identity pool for use with Amazon Location Service
There are two roles created by Cognito: an Auth_Role that grants signed-in-user-level access and an Unauth_Role that allows unauthenticated access to resources. Attach the following policies for the appropriate resources and roles (Auth and/or Unauth). Replace {region}, {account-id}, and {enter Map/PlaceIndex name} with the correct items. Note that certain actions cannot be performed with unauthenticated access. The list of actions allowed for the Unauth role is in the Granting access to Amazon Location Service guide.
{ "Version": "2012-10-17", "Statement": [ { "Sid": "GetTiles", "Effect": "Allow", "Action": [ "geo:GetMapTile", "geo:GetMapSprites", "geo:GetMapGlyphs", "geo:GetMapStyleDescriptor" ], "Resource": "arn:aws:geo:{region}:{account-id}:map/{enter Map name}" }, { "Sid": "Search", "Effect": "Allow", "Action": [ "geo:SearchPlaceIndexForPosition", "geo:SearchPlaceIndexForText" ], "Resource": "arn:aws:geo:{region}:{account-id}:place-index/{enter PlaceIndex name}" } ]}In your app configuration
Amplify Geo is dependent on your Amplify Auth category. If it is not already configured, then you will have to manually configure it as well. In order to manually configure Amplify Geo category, you must edit amplifyconfiguration.json in your project's src/main/res/raw directory with your information from existing Amazon Cognito and Amazon Location Service resources.
{ "UserAgent": "aws-amplify-cli/2.0", "Version": "1.0", "geo": { "plugins": { "awsLocationGeoPlugin": { "region": <YOUR_REGION>, "maps": { "items": { <YOUR_MAP_NAME>: { "style": <YOUR_MAP_STYLE> } }, "default": <DEFAULT_MAP_NAME> }, "searchIndices": { "items": [ <YOUR_INDEX_NAME> ], "default": <DEFAULT_INDEX_NAME> } } } }, "auth": { "plugins": { "awsCognitoAuthPlugin": { "UserAgent": "aws-amplify-cli/0.1.0", "Version": "0.1.0", "IdentityManager": { "Default": {} }, "CredentialsProvider": { "CognitoIdentity": { "Default": { "PoolId": <YOUR_IDENTITY_POOL_ID>, "Region": <YOUR_REGION> } } } } } }}Now you can proceed to displaying a map or adding location search to your app.
