Follow the instructions on this\npage to set up the Android 12 SDK in Android Studio and build and run your app\non Android 12.\n\nGet Android Studio\n------------------\n\nThe Android 12 SDK includes changes that are not compatible with some lower\nversions of Android Studio. For the best development experience with the Android\n12 SDK, use Android Studio Arctic Fox \\| 2020.3.1 or higher.\n\n[Get Android Studio](/studio)\n\nInstall the SDK\n---------------\n\nWithin Android Studio, you can install the Android 12 SDK as follows:\n\n1. Click **Tools \\\u003e SDK Manager** , then click **Show Package Details**.\n2. In the **SDK Platforms** tab, expand the **Android 12.0 (\"S\")** section and select the **Android SDK Platform 31** package.\n3. In the **SDK Tools** tab, expand the **Android SDK Build-Tools 34** section and select the latest `31.x.x` version.\n4. Click **Apply \\\u003e OK** to download and install the selected packages.\n\nUpdate your app's build configuration\n-------------------------------------\n\nTo access Android 12 APIs and test your app's compatibility with Android 12,\nopen your module-level `build.gradle` or `build.gradle.kts` file, and update the\n`compileSdkVersion` and `targetSdkVersion` with values for Android 12: \n\n### Groovy\n\n```groovy\nandroid {\n compileSdkVersion 31\n\n defaultConfig {\n targetSdkVersion 31\n }\n}\n```\n\n### Kotlin\n\n```kotlin\nandroid {\n compileSdkVersion(31)\n\n defaultConfig {\n targetSdkVersion(31)\n }\n}\n```\n| **Note:** If you aren't quite ready to fully support Android 12, you can still perform app compatibility testing by using a debuggable app, an Android 12 device, and the [compatibility framework](/about/versions/12/reference/compat-framework-changes), without changing either your app's `compileSdkVersion` or `targetSdkVersion`.\n\nTo learn about which changes might affect you, and to learn how to test these\nchanges in your app, read the following topics:\n\n- [Behavior changes that affect all apps](/about/versions/12/behavior-changes-all)\n- [Behavior changes that affect only apps that target Android 12](/about/versions/12/behavior-changes-12)\n\nTo learn more about new APIs and features available in Android 12, read [Android\n12 features](/about/versions/12/features)."]]
