    If you have an existing Android app and you simply want to run it on the N +Preview system image, then you need either a virtual device or a supported +hardware device configured with N Preview system image.

    + +

    Simply installing your app onto the N Preview this way does not require +any changes to your app source code. If, however, you want to update your +app to use new APIs in the N Preview and new language features of Java 8, +then you need to download Android Studio 2.1 (preview) as described in +Set Up to Develop for the +N Preview. + +

    So, although Android Studio 2.1 is required for development with N Preview +APIs, you can use Android Studio 1.5 or higher if you simply want to run your +app in the emulator or a connected device.

    + + +

    Set up a Virtual Device

    + +

    To use the Android Emulator to run the N Preview you need to download +the Android N Preview SDK and create a virtual device for the emulator. +

    + +

    First, downloaded the Android N Preview SDK as follows (if you +already got it while setting up +Android Studio 2.1, you can skip this part): + +

      +
    1. In Android Studio, open the Settings dialog + (File > Settings on Windows/Linux, or + Android Studio > Preferences on Mac). In the left + panel, select Appearance & Behavior > + System Settings > Android SDK. + +
    2. Click the SDK Platforms tab, then select the + Android N Preview check box.
      3. + +
    3. Click the SDK Tools tab, then select the + Android SDK Build Tools, Android SDK + Platform-Tools, and Android SDK Tools check + boxes. +
      4. + +
    4. Click OK and accept the license + agreements for any packages to be installed. +
      5. +
    + + +

    Now create a virtual device with the N Preview system image:

    + +
      +
    1. Open the AVD Manager by selecting Tools > Android > + AVD Manager.
      2. +
    2. Click Create Virtual Device.
      3. +
    3. Select a device such as Nexus 5X, Nexus 6P, Nexus 9, or Android TV, + then click Next.
      4. +
    4. Select the N system image (with the + x86 ABI), then click Next. +
    5. Complete the rest of the AVD configuration and click + Finish.
      6. +
    + +

    You can now launch the Android Emulator with the Android N Preview AVD.

    + +

    For more information about creating virtual devices, see Managing Virtual Devices. +

    + + + +

    Set Up a Hardware Device

    + +

    If you have a Nexus 5X, Nexus 6P, Nexus 9, Pixel C, or Nexus Player, you can +install the N Preview for testing your app.

    + +

    + Important: Installing a preview image on a device + removes all data from it, so you should backup any data before + installing a preview image. +

    + +

    - You must have a development enviroment to make use of the Android N Developer - Preview. This document describes how to setup and configure a development - environment so you can use and test the Preview SDK. +To develop apps for Android using new APIs in the N Preview and new language +features of Java 8, you need to set up Android Studio 2.1 (preview) as described +on this page.

    Get Android Studio 2.1 (preview)

    + +

    Developing for the Android N Preview platform requires Java 8 and a new +compiler toolchain called JACK, which is currently supported only in +Android Studio 2.1.

    -

    - This document assumes that you are familiar with Android app development, - such as using the Android SDK Manager and creating projects. If you are new - to Android, see - Building Your First - App training lesson first. -

    Android Studio 2.1 is currently available as a preview in the canary +release channel—it is still in development. If you already +have Android Studio and don't want to update to the canary channel, you can +download Android Studio 2.1 as a separate installation and use it +for use with the N Preview, leaving your primary Android Studio environment +unaffected.

    Get Android Studio 2.1

    - -

    - The Developer Preview is best used with Android Studio 2.1, which is also in - preview status. If you have an existing version of Android Studio you are - using for development, you should install a separate instance of Android - Studio for use with the Preview. This section describes how to install - an instance of Android Studio and update to version 2.1. -

    - -

    - Caution: The canary preview of Android Studio 2.1 is still - in active development. If you are using your primary development machine to - test the developer preview, you should create a second installation of - Android Studio to use for testing the Developer Preview. -
