Clona ed esegui i sample
Per eseguire questo esempio localmente è necessario Git. Il comando seguente clona il repository dell'applicazione di esempio.
git clone git@github.com:googlemaps-samples/android-samples.git
Importa il progetto di esempio in Android Studio:
- In Android Studio, seleziona File > Nuovo > Importa progetto.
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
- Seleziona Apri. Android Studio compila il progetto utilizzando lo strumento di compilazione Gradle.
- Crea un file
secrets.properties vuoto nella stessa directory del file local.properties del progetto. Per ulteriori informazioni su questo file, consulta Aggiungere la chiave API al progetto.
- Genera una chiave API dal tuo progetto con l'SDK Maps per Android abilitato.
Aggiungi la seguente stringa a secrets.properties, sostituendo YOUR_API_KEY con il valore della tua chiave API:
MAPS_API_KEY=YOUR_API_KEY
- Esegui l'app.
