如果您有Nexus 设备(Nexus device)并且喜欢使用最新版本的Android，那么您可能会很高兴得知您可以通过无线(Android N over-the-air)( OTA )将您的设备更新到Android N 的测试版。(beta version)您可以执行此操作的唯一设备是Nexus 6、Nexus 6P、Nexus 5X、Nexus 9、Nexus Player、Pixel C 和 General Mobile(Pixel C and General Mobile) 4G ( Android One )。
使用这些设备之一，您不必担心解锁引导加载程序或使用系统映像(system image)刷新设备。您所要做的就是注册Android Beta 计划(Android Beta Program)，注册您的设备，一切顺利！
我将引导您完成本文中的步骤，但请记住， Android(Android)的预发布版本通常不稳定，因此不要在您的主要设备上执行此操作。如果你做了之后后悔了，有一种方法可以恢复到上一个稳定版本的Android，我也会在下面解释。
加入 Android 测试版计划
第一步是加入测试计划(beta program)并注册您的设备。访问Android Beta 计划(Android Beta Program) 网站并(website and login)使用您的Google 帐户(Google account)凭据登录。使用您在Nexus 设备(Nexus device)上使用的同一帐户。
您应该会在页面中间看到符合条件的设备列表。如果您没有看到自己的设备，请确保它没有隐藏在Google Play中。单击(Click)注册设备(Enroll Device)按钮并接受许可协议。
安装 Android 测试版
该设备将被注册，您应该很快就会在手机上收到一条消息，表明您的手机现在可以使用更新。
点击通知，您会看到一条消息，其中包含将最新版本的Android下载到您的Nexus 设备(Nexus device)的链接。
该消息还提到了Android测试版的一些新功能。对于Android N，新功能包括多窗口支持、通知直接回复等。完全下载测试版后，您将收到另一个安装通知。
安装过程(install process)将需要 5 到 15 分钟，具体取决于您的设备。安装后，只要一切顺利，您应该可以正常登录设备。您可能还准备好一堆应用程序更新。
您始终可以通过转到设置(Settings)然后一直点击底部的关于手机(About Phone)来验证您正在运行Android N的测试版。(Android N)
最后，再次向下滚动到底部，您将看到Android 版本(Android build)号。
如果内部版本号(build number)以 NP 开头，则表示它是Android N的(Android N.)测试版(beta version)。如果您的设备上的Android测试版(beta version)有问题，您可以随时回滚到最新的稳定版本。
为此，只需重新登录Android Beta 计划网站(Android Beta Program website)，您就会看到一个取消注册设备( Unenroll Device)按钮。
当你点击它时，你会在你的设备上收到另一个通知，下载一个OTA 更新(OTA update)，它将擦除你手机上的所有内容并安装最新的公共稳定版Android。
总的来说，对于那些拥有Nexus 设备(Nexus device)的人来说，这是一个很棒的程序。如果您没有Nexus 设备(Nexus device)，则该过程要复杂得多，并且容易出错和失败。通过Beta 计划(Beta Program)，任何人都可以通过新的点击和点击来查看最新版本的Android 。在以后的文章(future post)中，我将讨论Android N 中的一些新功能。尽情享受(Android N. Enjoy)吧！
How to Update a Nexus Device OTA to Android N (7.0) Beta
If you have a Nexus device and love playing around with the latest vеrsions of Android, then you might be happy to learn that you can update your devicе to the beta version of Android N over-the-air (OTA). The only devices you can do this for are the Nexus 6, Nexus 6P, Nexus 5X, Nexus 9, Nexus Player, Pixel C and General Mobile 4G (Android One).
With one of these devices, you don’t have to worry about unlocking the bootloader or flashing your device using a system image. All you have to do is sign for the Android Beta Program, enroll your device and you’re good to go!
I’ll walk you through the steps in this article, but remember that pre-release versions of Android are normally unstable, so don’t do this on your primary device. If you do it and regret it later, there is a way to revert back to the last stable version of Android, which I will also explain below.
Join Android Beta Program
The first step is to join the beta program and enroll your device. Visit the Android Beta Program website and login with your Google account credentials. Use the same account that you are using on your Nexus device.
You should see a list of your eligible devices towards the middle of the page. If you don’t see your device, make sure it’s not hidden in Google Play. Click on the Enroll Device button and accept the license agreement.
Install Android Beta
The device will be enrolled and you should get a message on your phone fairly quickly, indicating that an update is now available for your phone.
Tap on the notification and you’ll see a message with a link to download the latest version of Android onto your Nexus device.
The message also mentions a couple of the new features for the beta version of Android. For Android N, new features include multi-window support, direct reply for notifications and more. Once the beta has been fully downloaded, you’ll get another notification to install it.
The install process will take anywhere from 5 to 15 minutes, depending on your device. Once installed, you should be able to login into your device normally as long as everything went well. You might also have a bunch of app updates ready.
You can always verify that you are running a beta version of Android N by going to Settings and then tapping on About Phone all the way at the bottom.
Finally, scroll down to the bottom again and you’ll see the Android build number.
If the build number starts with NP, that means it’s a beta version of Android N. If you are having problems with the beta version of Android on your device, you can always roll back to the latest stable version.
In order to do that, just log back into the Android Beta Program website and you’ll see an Unenroll Device button.
When you click on that, you’ll get another notification on your device to download an OTA update that will wipe everything on your phone and install the latest public stable version of Android.
Overall, it’s a great program for those who have a Nexus device. If you don’t have a Nexus device, the process is far more complicated and prone to errors and failures. With the Beta Program, anyone can check out the latest version of Android with just a new taps and clicks. In a future post, I’ll talk about some of the new features in Android N. Enjoy!
