Android “O“ is the upcoming version of Google’s mobile operating system, but you don’t have to wait until the release date to get your hands on the latest and greatest features. If you have a compatible Nexus or Pixel device, you can install the developer preview of Android O right now.

Android“ O”是即将推出的Google移动操作系统版本，但您不必等到发布日期就可以使用最新，最强大的功能。 如果您有兼容的Nexus或Pixel设备，则可以立即安装Android O的开发人员预览版。

什么是Beta /开发者预览版？ (What Is a Beta/Developer Preview?)

As the name implies, this is a way for developers to get eyes on what’s coming up in the next major Android release. Google started the developer preview program with Android L—which later became what we all now know as Lollipop—then improved the program with Android Nougat. And it’s carrying on now with the launch of O.

顾名思义，这是开发人员关注下一主要Android版本中即将发生的事情的一种方式。 Google使用Android L(后来被大家称为Lollipop)启动了开发人员预览程序，然后使用Android Nougat改进了该程序。 随着O的推出，它现在正在进行中。

In a nutshell, think of this as a public beta. It’s designed for developers to make sure their apps are update-ready when O becomes publicly available to all, but it’s also a great way for enthusiasts to see what’s going on behind the scenes before it’s ready for a major release. Keep in mind, though, that this is beta software, and it will have bugs here and there.

简而言之，可以将其视为公开测试版。 它是为开发人员设计的，以确保在O公开提供给所有人时，他们的应用程序都可以更新，但是，这也是发烧友在准备发布主要版本之前先了解幕后情况的好方法。 不过请记住，这是Beta版软件，并且在各处都会出现错误。

In other words, if you only have one phone, it’s probably not the best idea to test this preview on it. If you have an older Nexus (or a Pixel you don’t use) and want to peek at what’s coming, this is the perfect opportunity.

换句话说，如果您只有一部手机，那么在其上测试此预览可能不是最好的主意。 如果您有较旧的Nexus(或者您不使用的Pixel)，并且想了解一下即将发生的事情，那么这是绝佳的机会。

如何注册Android O Beta计划 (How to Enroll in the Android O Beta Program)

Like I mentioned earlier, Google improved on the developer program with Android Nougat, by offering users an easy way to “opt in” to the program and providing over-the-air (OTA) updates for compatible devices. It’s using this same design for the O preview, which is fantastic. You don’t have to unlock your bootloader or anything to use it, though it may be a good idea, since it’ll help you fix the device if anything goes wrong.

就像我之前提到的那样，Google通过为用户提供一种“加入”该程序的简便方法，并为兼容设备提供无线(OTA)更新，从而改进了Android Nougat开发程序。 它使用相同的设计进行O预览，这太棒了。 尽管可能是个好主意，但您不必解锁引导加载程序或任何使用它的方法，因为如果出现任何问题，它将帮助您修复设备。

If you have one of the devices mentioned above connected to your Google account, you can head here to get started with the beta program. After you sign in with your Google account, make sure to read all of the caveats before you just start clicking buttons. In particular: if you ever want to opt out of the beta program and roll back to the latest stable version of Android, your device will have to be wiped with a factory reset.

如果您将上述设备之一连接到Google帐户，则可以前往此处开始使用Beta版程序。 使用Google帐户登录后，请务必先阅读所有警告，然后再开始单击按钮。 特别是：如果您想退出测试版程序并回滚到最新的Android稳定版本，则必须使用出厂重置清除设备。

Once you’ve confirmed that you’re cool with the fact this may be super buggy on your device, you can simply hit the “Enroll Device” button below the eligible device you want to push N to.

一旦确认您对设备上的超级虫虫很满意，您只需点击要推入N的合格设备下方的“注册设备”按钮。

A popup will appear with a standard set of this may wreck your device warnings, so if that doesn’t scare you off, click the checkbox and press the “Join beta” button.

将显示一个弹出窗口，其中包含一组标准内容，这可能会破坏您的设备警告，因此，如果这不吓您一跳，请单击复选框，然后按“加入测试版”按钮。

Within a few minutes, the enrolled device should receive an update notification. This will install like any other update would—it downloads directly from Google, then flashes automatically.

在几分钟内，已注册的设备应会收到更新通知。 该安装将像其他任何更新一样进行安装-直接从Google下载并自动闪烁。

Upon reboot, you’ll be running Android O!

重新启动后，您将运行Android O！

如何手动刷新Android O (How to Flash Android O Manually)

The OTA method should work for most devices, but you can also flash it manually if you have problems. We’ve already covered how to update your Android device without waiting for an OTA, and flashing the Android O preview follows the same guidelines. While you can use the “flash-all” script found inside the download file, I’d recommend following the “What to Do If the Script Doesn’t Work” section of our guide just to ensure everything is flashed perfectly.

OTA方法适用于大多数设备，但是如果遇到问题，也可以手动刷新它。 我们已经介绍了如何在不等待OTA的情况下更新Android设备，并且按照相同的指导刷新Android O预览。 尽管您可以使用下载文件中的“ all-flash”脚本，但建议您遵循指南中的“如果脚本不起作用该怎么办”部分，以确保所有内容都能完美地刷新。

The primary difference is where you’ll find the update files. Instead of hosting them on the Factory Images for Nexus Devices page, Google keeps the developer preview files tucked away safely on its developer site. All you need to do is grab the appropriate download and follow the instructions in this guide to get things going.

主要区别是在哪里可以找到更新文件。 Google不会将其托管在Nexus设备的“工厂映像”页面上，而是将开发者预览文件安全地藏在其开发者网站上。 您需要做的就是获取适当的下载并按照本指南中的说明进行操作。

It’s worth mentioning that there’s no advantage to doing it this way since there’s an OTA program now, so this method should really only be used if you’re having issues pulling O through the enrollment program. Especially since it requires unlocking your bootloader to do.

值得一提的是，这样做是没有好处的，因为现在有了OTA程序，因此，仅当在通过注册程序来拉O时遇到问题时，才应使用此方法。 特别是因为它需要解锁您的引导加载程序才能执行。

如何回滚到牛轧糖，以及期望 (How to Roll Back to Nougat, and What to Expect)

OK, so you gave Android O a shot, fell in love with all sorts of neat stuff about it, but ultimately just couldn’t handle the bugginess. There’s no shame in that, and it’s super easy to roll back to a stable version of Nougat.

好的，所以您给了Android O一炮而红，迷上了各种精巧的东西，但最终却无法解决这些错误。 这没有什么可耻的，回滚到稳定版本的牛轧糖非常容易。

If you enrolled in the program using the OTA method, you need only go back to the Android Beta Program landing page and “unenroll” your device by clicking the button. Keep in mind here that this will perform a factory reset on your device, so if you’re OK with losing everything and starting over, go for it. There is currently no recommended way of rolling back without wiping the device. Back up anything you need before continuing!

如果您使用OTA方法注册了该程序，则只需返回至Android Beta程序登录页面，然后通过单击按钮“取消注册”您的设备。 请记住，这将在您的设备上执行出厂重置，因此，如果您确定丢失所有内容并重新开始都可以，请继续进行。 当前没有建议的不擦除设备就回滚的方法。 继续之前，请备份所需的任何内容！

If you manually flashed the update, you’ll just need to download the appropriate factory image for your device and flash it using the same instructions you used to flash the preview in the first place. Easy peasy.

如果您手动刷新了更新，则只需要为设备下载适当的出厂映像，然后按照与首先刷新预览相同的说明来对其进行刷新。 十分简单。
