La libreria di utilità di Maps SDK for Android supporta Android
API
livello 15 o superiore. Quando imposti il target di build del progetto, assicurati di utilizzare la versione
Livello API Android.
Passaggio 1. Installa la libreria dell'utilità di Maps SDK for Android
Aggiungi la seguente dipendenza al file build.gradle.kts dell'app:
dependencies{// Utility Library for Maps SDK for Android// You do not need to add a separate dependency for the Maps SDK for Android// since this library builds in the compatible version of the Maps SDK.implementation("com.google.maps.android:android-maps-utils:3.14.0")}
Passaggio 2: (Facoltativo) Installa la libreria KTX dell'utilità Maps SDK for Android
La libreria di utilità di Maps SDK for Android è dotata di estensioni Kotlin corrispondenti
(KTX). Questa libreria fornisce funzionalità del linguaggio Kotlin, come le funzioni di estensione,
e argomenti predefiniti per consentirti di scrivere Kotlin conciso e idiomatico. Se non sei
sviluppare in Kotlin, puoi saltare questo passaggio.
Per utilizzare questa libreria, aggiungi la seguente dipendenza, oltre alla
Dipendenza android-maps-utils, al file build.gradle.kts della tua app:
dependencies{// KTX for the Maps SDK for Android Utility Libraryimplementation("com.google.maps.android:maps-utils-ktx:5.2.0")}
Visita la pagina su GitHub KTX di Maps
per ulteriori informazioni su questa libreria.
Passaggio 3: Visualizzare il codice sorgente della libreria di utilità di Maps SDK for Android
Poiché la libreria di utilità è open source, puoi scaricare
android-maps-utils
nella tua macchina per personalizzarla, visualizzare l'app demo o semplicemente
all'operatività della biblioteca. A tale scopo, procedi nel seguente modo:
clonare il repository (consigliato,
di ricevere aggiornamenti automatici) o
download
un file ZIP. Se vuoi personalizzare la raccolta, devi
esegui il fork del repository.
Il repository include:
Un'applicazione demo, nella directory demo.
La libreria delle utilità, nella directory library.
Vari file contenenti licenze, collaboratori e informazioni sul file readme.
Configurazione di build Gradle, da utilizzare con Android Studio.
Esegui l'app demo dell'utilità
Il repository GitHub per la libreria di utilità viene fornito con un'app demo che include esempi
le implementazioni di ogni utilità. Segui questi passaggi per eseguire l'app demo su
il tuo dispositivo Android.
Scarica il repository utilizzando una delle opzioni indicate sopra.
In Android Studio, scegli File -> Nuovo -> Importa progetto.
Individua e seleziona (fai doppio clic) sul
android-maps-utils creata durante
ha clonato la libreria di utilità. Android Studio ora crea il progetto.
Se utilizzi un dispositivo Android anziché un emulatore, assicurati di
attivare la modalità sviluppatore.
Dopodiché collega il dispositivo Android al computer.
Aggiungi a local.properties una singola riga che abbia il seguente aspetto:
L'app dovrebbe aprirsi sul dispositivo Android e mostrare un elenco di utilità
tra cui clustering, poyutil, Heatmap e altro ancora. Puoi trovare l'app anche in
il tuo elenco di app, sotto il nome Maps Utils Demo.

When setting your project build target, make sure you use the latest\nAndroid API level.\n\nThe\n[reference\ndocumentation](http://googlemaps.github.io/android-maps-utils/javadoc/) is available on GitHub.\n\nStep 1. Install the Maps SDK for Android utility library\n\nAdd the following dependency to your app's `build.gradle.kts` file: \n\n```carbon\ndependencies {\n\n\n // Utility Library for Maps SDK for Android\n // You do not need to add a separate dependency for the Maps SDK for Android\n // since this library builds in the compatible version of the Maps SDK.\n implementation(\"com.google.maps.android:android-maps-utils:3.14.0\")\n}\n```\n\nUse one of the utilities from the library, such as\n[marker\nclustering](/maps/documentation/android-sdk/utility/marker-clustering),\n[heatmaps](/maps/documentation/android-sdk/utility/heatmap), or\nthe [other\nutilities](/maps/documentation/android-sdk/utility).\n\nStep 2. (Optional) Install the Maps SDK for Android utility KTX library\n\nThe Maps SDK for Android utility library comes with a corresponding Kotlin extensions\n(KTX) library. This library provides Kotlin language features---such as extension functions, named\nand default arguments---to enable you to write concise and idiomatic Kotlin. If you are not\ndeveloping in Kotlin, you can skip this step.\n\nTo use this library, add the following dependency, in addition to the\n`android-maps-utils` dependency, to your app's `build.gradle.kts` file: \n\n```carbon\ndependencies {\n\n // KTX for the Maps SDK for Android Utility Library\n implementation(\"com.google.maps.android:maps-utils-ktx:5.2.0\")\n}\n```\n\nCheck out the [Maps KTX GitHub](https://github.com/googlemaps/android-maps-ktx) page\nfor additional information about this library.\n\nStep 3. View the Maps SDK for Android utility library source code\n\nSince the utility library is open source, you can download the\n[android-maps-utils](https://github.com/googlemaps/android-maps-utils)\nlibrary to your machine to customize it, view the demo app, or if you just want to understand how\nthe library works. You can do so by\n[cloning](https://github.com/googlemaps/android-maps-utils.git) the repo (recommended,\nto receive automatic updates) or\n[downloading\na zip file](https://github.com/googlemaps/android-maps-utils/archive/master.zip). If you want to customize the library, you should\n[fork the repo](https://help.github.com/articles/fork-a-repo).\n\nThe repository includes:\n\n- A demo application, in the `demo` directory.\n- The library of utilities, in the `library` directory.\n- Various files containing license, contributors, and readme information.\n- Gradle build configuration, for use with Android Studio.\n\nRun the utility demo app\n\nThe GitHub repository for the utility library ships with a demo app that includes sample\nimplementations of each utility. Follow these steps to run the demo app on\nyour Android device.\n\n1. Download the repository using one of the options mentioned above.\n2. In Android Studio, choose **File -\\\u003e New -\\\u003e Import Project**.\n3. Browse to and select (double-click) the **android-maps-utils** directory that was created when you cloned the utility library. Android Studio now builds the project.\n4. If you are using an Android device instead of an emulator, make sure to [enable developer mode](https://developer.android.com/tools/device.html#setting-up). Then attach the Android device to your computer.\n5. Add a single line to `local.properties` that looks like this:\n\n ```scdoc\n MAPS_API_KEY=YOUR_API_KEY\n ```\n\n Where \u003cvar translate=\"no\"\u003eYOUR_API_KEY\u003c/var\u003e is the API key you obtained as described in\n [Using API Keys](/maps/documentation/android-sdk/get-api-key).\n6.
