侧载是将文件和程序从一个设备本地移动到另一个设备的过程。通常，这意味着将您的计算机连接到智能手机或平板电脑。对于大多数人来说，侧载不是他们永远需要做的事情，但知道如何去做可能是一项方便的技能。
但什么是侧载？但是，在执行此操作之前，您需要了解一些重要事项，因为其中涉及潜在的安全风险，并且在某些情况下，它可能会使您的设备保修失效(your device’s warranty)。
什么是侧载以及它是如何(How)工作的？
对于我们的大多数设备，我们通过从 Internet 下载文件和软件来获取它们。通常，这是通过我们设备制造商提供的软件实现的。对于计算机，这将是浏览器或软件商店。Android和 iOS 分别使用Play Store和App Store。
旁加载通过将软件直接放置到您的设备上来避免这些方法。这通常以下列方式之一发生：
- USB 侧载–(USB sideloading )使用 USB 电缆(using a USB cable)在设备之间移动文件和软件。
- 蓝牙侧载(Bluetooth sideloading)——使用蓝牙连接(a Bluetooth connection)在设备之间移动数据。
- 外部存储侧载(External Storage sideloading)– 使用 USB 驱动器或microSD 卡(microSD card)在设备之间传输。
大多数程序都包含有关如何安装操作系统的说明。无论(Whether)您是从官方来源获取软件还是旁加载软件，一旦在硬盘驱动器上，您的设备通常不会检测到任何差异。
为什么要侧载？
虽然您需要的大多数应用程序都可以通过官方应用程序商店获得，但也有例外。也许最引人注目的例子是Fortnite的移动版本。发布时，流行的皇家大逃杀游戏在Google Play 商店(Google Play Store)中不可用，并且要求用户将游戏侧载到他们的智能手机上。
Epic Games并不是唯一热衷于避免在Google或 Apple 的官方渠道发布其应用程序的开发商。APK Mirror和vShare Download等网站托管了数千个适用于Android和 iOS 设备的可下载应用程序。
侧载的另一个常见原因是访问旧版本的应用程序，或者通过传统方法不再可用的应用程序。这对于智能家居应用程序(smart home apps)特别方便，强制更新后特别容易出错。
最后，在某些地区，智能设备无法轻松访问互联网。从共享计算机旁加载应用程序使人们可以自由地享受通常为直接访问App或Play商店的人保留的软件。
侧载安全吗？
虽然侧载并不违法，但在开始之前有一些事情需要考虑。侧载应用程序没有与官方下载相同的安全保证。只要您信任应用程序的来源，这不是问题，但您可能会在没有意识到的情况下安装恶意间谍软件。
直到最近，iOS 上的侧载需要手机越狱。越狱(Jailbreaking)是绕过苹果(Apple)官方系统向iOS设备添加文件和软件的过程。不幸的是，这也会使手机的保修失效，甚至可能导致苹果(Apple)官方供应商拒绝维修您的设备。
虽然侧载不再需要越狱(no longer requires jailbreaking)，但苹果(Apple)并未明确说明侧载是否也会破坏用户保修。
如何在 Android 设备上侧载
如上面的视频所示，像Racoon这样的软件可以让搜索和传输应用程序变得更加容易。但是，在大多数情况下，您可以通过USB或蓝牙将任何下载的(Bluetooth)APK 文件(APK file)传输到您的智能设备，而无需任何额外的软件。您可能会发现需要更改安全设置才能使用此方法。
对于 Android Nougat 用户：
- 选择安全性(Security)（有时称为锁定屏幕和安全性(Lock Screen and Security)）。
- 在设备管理(Device Administration)部分启用未知来源。(Unknown Sources)
对于安卓奥利奥用户：
- 选择应用程序和通知(Apps and Notification)。
- 启用安装未知应用程序(Install Unknown Apps)（有时称为安装其他应用程序(Install Other Apps)）。
在您的Android设备上打开一个APK会安装它，它会像任何其他应用程序一样出现在菜单中。
如何在 iOS 设备上侧载
对于 iOS 用户来说，sideloading 曾经是一个困难的过程，包括越狱你的设备。如今，它更易于管理。Altstore等软件允许通过(Software)USB电缆直接安装IPA文件。
它仍然比Android(Android) sideloading稍微复杂一些，但上面的教程将引导您完成设置所需的每个步骤。
在 Android TV 上侧载
Android TV 用户还可以旁加载应用程序，正如上面的视频所示，有多种方法可以实现这一点。如果您想使用 VPN 观看区域锁定的电视节目，(use a VPN to watch region-locked television shows)这将特别有用。
Oculus Quest 侧载
Oculus Quest(The Oculus Quest)可让您在不受电脑束缚的情况下玩游戏。虽然这比传统的 VR 头显提供了更大的自由度，但您只能使用Oculus 商店(Oculus Store)中提供的应用程序。
旁加载允许访问其他游戏和软件，以及Steam Link和远程桌面软件。别忘了，如果您有Oculus (Don)Quest ，您还可以(Oculus Quest)使用 Oculus Link(using the Oculus Link)解锁成熟的 VR 游戏的力量。
侧载：一项有用的技能
侧载为您提供了更多选项来控制智能设备上的应用程序。它在应用程序开发中也是必不可少的，专门用于应用程序开发的编程语言需求量很大(programming languages specializing in app development are in high demand)。
What Is Sideloading?
Sideloading is the process of moνing files and рrograms locally from one device to another. Usually, this meanѕ connecting your computer to a smartphone or tablet. For most people, sidelоading isn’t something that they’ll ever need to do, but knowing how to do it could be a handy skill.
But what is sideloading? There are some important things you need to know before you do it, however, as there are potential security risks involved, and in some cases, it can void your device’s warranty.
What Is Sideloading And How Does It Work?
For most of our devices, we get files and software by downloading them from the internet. Usually, this is through software provided by our device’s manufacturer. For computers, this will be the browser or software store. Android and iOS use the Play Store and the App Store, respectively.
Sideloading avoids these methods by placing software directly onto your device. This usually happens in one of the following ways:
Most programs contain instructions to the operating system for how they should be installed. Whether you get the software from an official source or sideload it, once on the hard drive, your device usually won’t detect any difference.
Why Would You Want To Sideload?
While most apps you’ll need are available via an official app store, there are exceptions. Perhaps the most high profile example was the mobile version of Fortnite. On release, the popular battle royal game wasn’t available on the Google Play Store and required users to sideload the game on to their smartphones.
Epic Games aren’t the only developers keen to avoid publishing their app on Google or Apple’s official outlets. Sites like APK Mirror and vShare Download host thousands of downloadable apps for Android and iOS devices.
Another common reason to sideload is to get access to an older version of an app, or one that is no longer available through conventional methods. This is especially handy for smart home apps, which are particularly prone to error after forced updates.
Finally, in some areas, smart devices cannot readily access the internet. Sideloading apps from a shared computer gives people the freedom to enjoy software usually reserved for those directly accessing the App or Play store.
Is Sideloading Safe?
While sideloading isn’t illegal, there are some things to consider before getting started. Sideloaded apps don’t come with the same security assurances as official downloads. This is not a problem as long as you trust the source of the app, but you could be installing malicious spyware without realizing it.
Until recently, sideloading on iOS required the phone to be jailbroken. Jailbreaking is the process of bypassing Apple’s official system for adding files and software to iOS devices. Unfortunately, it also voids the phone’s warranty and may even result in official Apple vendors refusing to repair your device.
While sideloading no longer requires jailbreaking, Apple has not made it clear if sideloading will also break user warranties.
How To Sideload On Android Devices
As the above video shows, software like Racoon can make searching for and transferring apps easier. In most cases, however, you can transfer any downloaded APK file to your smart device via USB or Bluetooth without any additional software. You may find you need to change your security settings to use this method.
For Android Nougat users:
- Select Security (sometimes called Lock Screen and Security).
- Enable Unknown Sources in the Device Administration section.
For Android Oreo users:
- Select Apps and Notification.
- Enable Install Unknown Apps (sometimes called Install Other Apps).
Opening an APK on your Android device will install it, and it will appear in the menu like any other app.
How To Sideload On iOS Devices
For iOS users, sideloading used to be a difficult process, including jailbreaking your device. Nowadays, it’s much more manageable. Software like Altstore allows the direct installation of IPA files via USB cable.
It’s still slightly more complicated than Android sideloading, but the above tutorial takes you through each step required to get set up.
Sideloading On Android TV
Android TV users can also sideload apps, and as the above video shows, there are multiple ways to achieve this. This is particularly useful if you want to use a VPN to watch region-locked television shows.
Sideloading On The Oculus Quest
The Oculus Quest lets you play games without being tethered to a computer. While this allows much greater freedom than traditional VR headsets, you are limited to apps available on the Oculus Store.
Sideloading grants access to other games and software, along with Steam Link and remote desktop software. Don’t forget, if you have an Oculus Quest, you can also unlock the power of fully-fledged VR gaming using the Oculus Link.
Sideloading: A Useful Skill
Sideloading gives you more options for controlling what apps are on your smart devices. It’s also essential in app development, and programming languages specializing in app development are in high demand.
