Per un'esperienza ottimale di sviluppo con Compose, scarica e installa Android
Studio. Include molte funzionalità dell'editor intelligente, come nuovi modelli di progetto e la possibilità di visualizzare immediatamente l'anteprima dell'interfaccia utente e delle animazioni di Compose.
Segui queste istruzioni per creare un nuovo progetto di app Compose, configurare
Compose per un progetto di app esistente o importare un'app di esempio scritta in Compose.
Crea una nuova app con supporto per Compose
Se vuoi avviare un nuovo progetto che includa il supporto di Compose per impostazione predefinita,
Android Studio include vari modelli di progetto per aiutarti a iniziare. Per
creare un nuovo progetto con Compose configurato correttamente, procedi nel seguente modo:
Se ti trovi nella finestra Benvenuto in Android Studio, fai clic su Avvia un nuovo
progetto Android Studio. Se hai già aperto un progetto Android Studio,
seleziona File > Nuovo > Nuovo progetto dalla barra dei menu.
Nella finestra Seleziona un modello di progetto, seleziona Attività
vuota e fai clic su Avanti.
Nella finestra Configura il progetto:
Imposta Nome, Nome pacchetto e Posizione di salvataggio come di consueto. Tieni presente che, nel menu a discesa Lingua, Kotlin è l'unica
opzione disponibile perché Jetpack Compose funziona solo con le classi scritte in
Kotlin.
Nel menu a discesa Livello API minimo, seleziona il livello API 21 o superiore.
Fai clic su Fine.
Ora puoi iniziare a sviluppare un'app utilizzando Jetpack Compose. Per iniziare e scoprire cosa puoi fare con il toolkit, prova il tutorial su Jetpack
Compose.
Quindi, aggiungi la seguente definizione al file build.gradle della tua app:
Trendy
android{buildFeatures{composetrue}}
Kotlin
android{buildFeatures{compose=true}}
L'impostazione del flag compose su true all'interno del blocco BuildFeatures
di Android attiva la funzionalità Compose in Android Studio.
Infine, aggiungi la distinta base di Compose e il sottoinsieme delle dipendenze della libreria Compose
che ti servono alle tue dipendenze dal seguente blocco:

Prova le app di esempio di Jetpack Compose
Il modo più veloce per sperimentare le funzionalità di Jetpack Compose è
provare le app di esempio Jetpack Compose ospitate su GitHub. Per importare
un progetto di app di esempio da Android Studio, procedi nel seguente modo:
Se ti trovi nella finestra Benvenuto in Android Studio, seleziona Importa un
esempio di codice Android. Se hai già aperto un progetto Android Studio,
seleziona File > Nuovo > Importa esempio dalla barra dei menu.
Nella barra di ricerca nella parte superiore della procedura guidata Sfoglia esempi, digita
"compose".
Seleziona una delle app di esempio Jetpack Compose dai risultati di ricerca e fai clic su Avanti.
Modifica il Nome applicazione e la Posizione progetto oppure mantieni i valori predefiniti.
Fai clic su Fine.
Android Studio scarica l'app di esempio nel percorso specificato e apre il
progetto. Puoi quindi esaminare MainActivity.kt in ciascuno degli esempi per vedere
le API Jetpack Compose come l'animazione crossfade, i componenti personalizzati, l'utilizzo
della tipografia e la visualizzazione dei colori chiari e scuri nell'anteprima nell'IDE.

It includes many [smart editor features](/develop/ui/compose/tooling), such as new project\ntemplates and the ability to immediately preview your Compose UI and animations.\n\n[Get Android Studio](/studio)\n\nFollow these instructions to create a new Compose app project, set up\nCompose for an existing app project, or import a sample app written in Compose.\n\nCreate a new app with support for Compose\n-----------------------------------------\n\nIf you want to start a new project that includes support for Compose by default,\nAndroid Studio includes various project templates to help you get started. To\ncreate a new project that has Compose setup correctly, proceed as follows:\n\n1. If you're in the **Welcome to Android Studio** window, click **Start a new\n Android Studio project** . If you already have an Android Studio project open , select **File \\\u003e New \\\u003e New Project** from the menu bar.\n2. In the **Select a Project Template** window, select **Empty\n Activity** and click **Next**.\n3. In the **Configure your project** window, do the following:\n 1. Set the **Name, Package name** , and **Save location** as you normally would. Note that, in the **Language** dropdown menu, **Kotlin** is the only available option because Jetpack Compose works only with classes written in Kotlin.\n 2. In the **Minimum API level dropdown** menu, select API level 21 or higher.\n4. Click **Finish**.\n\nNow you're ready to start developing an app using Jetpack Compose. To help you\nget started and learn about what you can do with the toolkit, try the [Jetpack\nCompose tutorial](/develop/ui/compose/tutorial).\n\nSet up Compose for an existing app\n----------------------------------\n\nFirst, configure the Compose compiler using the [Compose\nCompiler Gradle plugin](/develop/ui/compose/compiler).\n\nThen, add the following definition to your app's `build.gradle` file: \n\n### Groovy\n\n android {\n buildFeatures {\n compose true\n }\n }\n\n### Kotlin\n\n android {\n buildFeatures {\n compose = true\n }\n }\n\nSetting the `compose` flag to `true` inside the Android [`BuildFeatures`](/reference/tools/gradle-api/7.0/com/android/build/api/dsl/BuildFeatures)\nblock enables [Compose functionality](/develop/ui/compose/tooling) in Android Studio.\n\nFinally, add the Compose BOM and the subset of Compose library dependencies\nyou need to your dependencies from the following block: \n\n### Groovy\n\n dependencies {\n\n def composeBom = platform('androidx.compose:compose-bom:2025.08.00')\n implementation composeBom\n androidTestImplementation composeBom\n\n // Choose one of the following:\n // Material Design 3\n implementation 'androidx.compose.material3:material3'\n // or Material Design 2\n implementation 'androidx.compose.material:material'\n // or skip Material Design and build directly on top of foundational components\n implementation 'androidx.compose.foundation:foundation'\n // or only import the main APIs for the underlying toolkit systems,\n // such as input and measurement/layout\n implementation 'androidx.compose.ui:ui'\n\n // Android Studio Preview support\n implementation 'androidx.compose.ui:ui-tooling-preview'\n debugImplementation 'androidx.compose.ui:ui-tooling'\n\n // UI Tests\n androidTestImplementation 'androidx.compose.ui:ui-test-junit4'\n debugImplementation 'androidx.compose.ui:ui-test-manifest'\n\n // Optional - Included automatically by material, only add when you need\n // the icons but not the material library (e.g. when using Material3 or a\n // custom design system based on Foundation)\n implementation 'androidx.compose.material:material-icons-core'\n // Optional - Add full set of material icons\n implementation 'androidx.compose.material:material-icons-extended'\n // Optional - Add window size utils\n implementation 'androidx.compose.material3.adaptive:adaptive'\n\n // Optional - Integration with activities\n implementation 'androidx.activity:activity-compose:1.10.1'\n // Optional - Integration with ViewModels\n implementation 'androidx.lifecycle:lifecycle-viewmodel-compose:2.8.5'\n // Optional - Integration with LiveData\n implementation 'androidx.compose.runtime:runtime-livedata'\n // Optional - Integration with RxJava\n implementation 'androidx.compose.runtime:runtime-rxjava2'\n\n }\n\n### Kotlin\n\n dependencies {\n\n val composeBom = platform(\"androidx.compose:compose-bom:2025.08.00\")\n implementation(composeBom)\n androidTestImplementation(composeBom)\n\n // Choose one of the following:\n // Material Design 3\n implementation(\"androidx.compose.material3:material3\")\n // or Material Design 2\n implementation(\"androidx.compose.material:material\")\n // or skip Material Design and build directly on top of foundational components\n implementation(\"androidx.compose.foundation:foundation\")\n // or only import the main APIs for the underlying toolkit systems,\n // such as input and measurement/layout\n implementation(\"androidx.compose.ui:ui\")\n\n // Android Studio Preview support\n implementation(\"androidx.compose.ui:ui-tooling-preview\")\n debugImplementation(\"androidx.compose.ui:ui-tooling\")\n\n // UI Tests\n androidTestImplementation(\"androidx.compose.ui:ui-test-junit4\")\n debugImplementation(\"androidx.compose.ui:ui-test-manifest\")\n\n // Optional - Included automatically by material, only add when you need\n // the icons but not the material library (e.g. when using Material3 or a\n // custom design system based on Foundation)\n implementation(\"androidx.compose.material:material-icons-core\")\n // Optional - Add full set of material icons\n implementation(\"androidx.compose.material:material-icons-extended\")\n // Optional - Add window size utils\n implementation(\"androidx.compose.material3.adaptive:adaptive\")\n\n // Optional - Integration with activities\n implementation(\"androidx.activity:activity-compose:1.10.1\")\n // Optional - Integration with ViewModels\n implementation(\"androidx.lifecycle:lifecycle-viewmodel-compose:2.8.5\")\n // Optional - Integration with LiveData\n implementation(\"androidx.compose.runtime:runtime-livedata\")\n // Optional - Integration with RxJava\n implementation(\"androidx.compose.runtime:runtime-rxjava2\")\n\n }\n\n| **Note:** Jetpack Compose is shipped using a Bill of Materials (BOM), to keep the versions of all library groups in sync. Read more about it in the [Bill of\n| Materials page](/develop/ui/compose/bom/bom).\n\nTry Jetpack Compose sample apps\n-------------------------------\n\nThe fastest way to experiment with the capabilities of Jetpack Compose is by\ntrying [Jetpack Compose sample apps](https://github.com/android/compose-samples) hosted on GitHub. To import\na sample app project from Android Studio, proceed as follows:\n\n1. If you're in the **Welcome to Android Studio** window, select **Import an\n Android code sample** . If you already have an Android Studio project open, select **File \\\u003e New \\\u003e Import Sample** from the menu bar.\n2. In the search bar near the top of the **Browse Samples** wizard, type \"compose\".\n3. Select one of the Jetpack Compose sample apps from the search results and click **Next**.\n4. Either change the **Application name** and **Project location** or keep the default values.\n5. Click **Finish**.\n\nAndroid Studio downloads the sample app to the path you specified and opens the\nproject. You can then inspect `MainActivity.kt` in each of the examples to see\nJetpack Compose APIs such as crossfade animation, custom components, using\ntypography, and displaying light and dark colors in the in-IDE preview.\n\nTo use Jetpack Compose for Wear OS, see [Set up Jetpack Compose on Wear OS](/training/wearables/compose-setup).\n\nRecommended for you\n-------------------\n\n- Note: link text is displayed when JavaScript is off\n- [Navigating with Compose](/develop/ui/compose/navigation)\n- [Testing your Compose layout](/develop/ui/compose/testing)\n- [React to focus](/develop/ui/compose/touch-input/focus/react-to-focus)"]]
