Esse exemplo identifica um local no mapa com marcador avançado e demonstra alguns dos recursos dos marcadores avançados.
Para mais detalhes, consulte a documentação.
Vamos começar
Antes de testar um exemplo de código, é preciso configurar o ambiente de desenvolvimento. Confira mais detalhes em Exemplos de código do SDK do Maps para Android.

Clonar e executar as amostras
O Git é necessário para executar esta amostra localmente. O comando a seguir clona o repositório do aplicativo de exemplo.
git clone git@github.com:googlemaps-samples/android-samples.git
Importe o projeto de amostra no Android Studio:
- No Android Studio, selecione File > New > Import Project.
Acesse o local onde você salvou o repositório e selecione o diretório do projeto para Kotlin ou Java:
- Kotlin:
PATH-REPO/android-samples/ApiDemos/kotlin - Java:
PATH-REPO/android-samples/ApiDemos/java
- Kotlin:
- Clique em Open. O Android Studio cria seu projeto usando a ferramenta Gradle.
- Crie um arquivo
secrets.propertiesem branco no mesmo diretório do arquivolocal.propertiesdo seu projeto. Confira mais informações em Adicionar sua chave de API ao projeto. Adicione a seguinte string a
secrets.properties, substituindo YOUR_API_KEY pelo valor da sua chave de API:MAPS_API_KEY=YOUR_API_KEY- Execute o app.
