clona ed esegui gli esempi

Per eseguire questo esempio in locale è necessario Git. Il seguente comando clona l'esempio un repository di applicazioni.

git clone git@github.com:googlemaps-samples/android-samples.git

Importa il progetto di esempio in Android Studio:

  1. In Android Studio, seleziona File > Nuovo > Importa progetto.

  2. Vai alla posizione in cui hai salvato il repository e seleziona la directory del progetto per Kotlin o Java:

    • Kotlin: PATH-REPO/android-samples/ApiDemos/kotlin
    • Java: PATH-REPO/android-samples/ApiDemos/java
  3. Seleziona Apri. Android Studio crea il tuo progetto utilizzando la build Gradle lo strumento a riga di comando gcloud.
  4. Crea un file secrets.properties vuoto nella stessa directory del file local.properties del progetto. Per ulteriori informazioni, consulta Aggiungere la chiave API al progetto.

  5. Aggiungi la seguente stringa a secrets.properties, sostituendo YOUR_API_KEY con il valore di la chiave API:

    MAPS_API_KEY=YOUR_API_KEY
  6. Esegui l'app.
