Here is how to download the preview on your device.
If you have access to a compatible device, enroll the device in automatic OTA system updates through the Android Beta Programme. Once enrolled, your device will receive regular over-the-air (OTA) updates of all milestone builds in the Android 8.1 Developer Preview. When the next version of Android is released, your device will automatically update to the final version.
Download a Developer Preview system image and flash the device. OTA updates will not be provided automatically for devices that you flash manually, but you can enroll those devices in Android Beta Programme to get OTA updates. When the next version of Android is released, you can download the final device image from the factory images page.
You can un-enroll a device at any time. The device will receive an OTA update to the most recent production version of Android available for that device (for example, Android 7.1 Nougat). The update requires a full device reset, so user data on the device will be removed. Make sure to back up important data before un-enrolling a device.
