With clear instructions and essential warnings, we’ll empower you to experience the latest Android innovations firsthand.

Navigating the Developer Preview:

It’s important to understand that the Android N Developer Preview is specifically designed for developers. This version is not yet polished for general consumer use and may contain bugs or inconsistencies. It’s crucial to back up your device fully before embarking on the installation process, as potential data loss is a risk.

Method 1: Installing via Factory Image

For tech-savvy users comfortable with flashing Android builds, the factory image method offers a direct route to the Developer Preview. Here’s a step-by-step guide:

Prerequisites:

• Android Studio Preview: Ensure you have the latest version installed on your system. It bundles essential tools like ADB and Fastboot, which are instrumental in flashing the image.
• Basic ADB/Fastboot knowledge: Familiarity with these tools is key to navigating the command-line interface during the installation.

Steps:

1. Download the Factory Image: Head to the official Android Developer website and locate the correct factory image for your device. Supported devices include the Nexus 6P, Nexus 5X, Nexus 6, Nexus Player, Nexus 9, and Pixel C.
2. Enable USB Debugging: Navigate to Settings > Developer options > USB debugging on your device and tick the checkbox.
3. Extract the Images: Unzip the downloaded factory image file and save it to your computer for easy access.
4. Connect Your Device: Plug your device into your computer using a USB cable.
5. Boot into Fastboot Mode: To access the bootloader, use the command adb reboot bootloader in the command terminal. (You may need to enable Developer options and OEM unlocking beforehand for this to work.)
6. Navigate to the Image Directory: Use your command terminal to navigate to the directory containing the extracted factory image files.
7. Execute “flash-all.bat”: Running this batch file will initiate the installation, flashing the necessary components, including the bootloader, baseband firmware, and the Android N Developer Preview.
8. Wait for Completion: The installation process may take significant time, and you’ll likely see multiple reboots during this phase. Be patient and let the system complete its work.

Method 2: Installing via OTA Update

The OTA update method offers a user-friendly and convenient approach to installing the Developer Preview. By joining the Android Beta Program, you’ll receive updates over-the-air without needing to flash your device manually.

Steps:

1. Visit g.co/androidbeta: Open this website on your desktop or mobile browser.
2. Sign in with Google Account: Use the Google account associated with the eligible device you wish to enroll in the Beta Program.
3. Enroll Device: Select the "Enroll Device" option under "Your Eligible Devices" for the device you want to update.
4. Agree to Terms and Conditions: Carefully read and accept the terms before clicking “Join Beta”.
5. Check for Updates: Navigate to Settings > About > System Updates on your device to see if an update is pending.
6. Install Update: If an update is available, follow the on-screen prompts to install the Android N Developer Preview.

Opting Out of the Beta:

Once you’ve had a chance to explore the Developer Preview, you can opt out of the Beta Program at any time. However, remember that this process will wipe all data on your device and return you to the stable public version of Android.
