Launch Apollo Studio

Get started with Java


Apollo Android 3 is available in beta. It is still in active development, and we'd love for folks to test it out. See the v3 documentation and please report any issues!

Add the Gradle plugin

In your app Gradle file, apply the com.apollographql.apollo plugin:

Using the plugins DSL:

plugins {
  // ...
  id("com.apollographql.apollo").version("x.y.z")
}

Or using the legacy syntax:

buildscript {
  // ...
  classpath("com.apollographql.apollo:apollo-gradle-plugin:x.y.z")
}

apply plugin: "com.apollographql.apollo"

The plugin is hosted on the Gradle plugin portal, Jcenter and Maven Central.

Add the runtime dependencies

dependencies {
  implementation("com.apollographql.apollo:apollo-runtime:x.y.z")
}

Download your schema.json file

Apollo Android requires your GraphQL server's schema as a schema.json file. You can obtain the contents of this file by running an introspection query on your server.

Note: If you don't have a GraphQL server yet, you can use the server from the tutorial: https://apollo-fullstack-tutorial.herokuapp.com/graphql.

The Apollo Gradle plugin exposes a downloadApolloSchema task to help you obtain your schema. Provide this task your server's GraphQL endpoint and the output location for the schema.json file:

(shell)
./gradlew downloadApolloSchema \
  --endpoint="https://your.domain/graphql/endpoint" \
  --schema="src/main/graphql/com/example/schema.json"

If your GraphQL endpoint requires authentication, you can pass custom HTTP headers:

(shell)
./gradlew downloadApolloSchema \
  --endpoint="https://your.domain/graphql/endpoint" \
  --schema="app/src/main/graphql/com/example" \
  --header="Authorization: Bearer $TOKEN"

Add your query

  1. Create a directory for your GraphQL files: src/main/graphql/com/example/
  2. Add your schema.json to the directory: src/main/graphql/com/example/schema.json
  3. Put your query in a .graphql file, next to the schema: src/main/graphql/com/example/LaunchDetails.graphql
src/main/graphql/com/example/LaunchDetails.graphql
query LaunchDetails($id:ID!) {
  launch(id: $id) {
    id
    site
    mission {
      name
      missionPatch(size:LARGE)
    }
  }
}
  1. Build your project, this will generate the model

Executing your query

You use an instance of the ApolloClient class to interact with your server and cache.

To make a query using your generated models:

// First, create an `ApolloClient`
// Replace the serverUrl with your GraphQL endpoint
ApolloClient apolloClient = ApolloClient.builder()
        .serverUrl("https://your.domain/graphql/endpoint")
        .build();

// Then enqueue your query
apolloClient.query(new LaunchDetailsQuery("83"))
        .enqueue(new ApolloCall.Callback<LaunchDetailsQuery.Data>() {
            @Override
            public void onResponse(@NotNull Response<LaunchDetailsQuery.Data> response) {
                Log.e("Apollo", "Launch site: " + response.getData().launch.site);
            }

            @Override
            public void onFailure(@NotNull ApolloException e) {
                Log.e("Apollo", "Error", e);
            }
        });
