Android: Simulate WiFi in the emulator?
提问by Felix
I would like to check from my app whether the device has WiFi connectivity, but in order to do that, I must first find a way to get "WiFi" in the emulator. Just going to Settings -> Wireless controls -> Wifisays Unable to start Wi-Fi, while logcatsays:
我想从我的应用程序中检查设备是否具有 WiFi 连接，但为了做到这一点，我必须首先找到一种在模拟器中获取“WiFi”的方法。只需转到Settings -> Wireless controls -> Wifi说Unable to start Wi-Fi，而logcat说：
E/WifiService( 566): Failed to load Wi-Fi driver.
D/SettingsWifiEnabler( 695): Received wifi state changed from Unknown to Enabling
D/SettingsWifiEnabler( 695): Received wifi state changed from Enabling to Unknown
How can I simulate WiFi connectivity in the emulator?

Since this seems to be a popular question, I'll go ahead and add an updated answer. The SDK still doesn't support WiFi emulation, but Genymotiondoes WiFi by default, so you can use that to develop/test apps with specific WiFi functionality.
由于这似乎是一个受欢迎的问题，我将继续添加更新的答案。SDK 仍然不支持 WiFi 仿真，但Genymotion默认支持 WiFi ，因此您可以使用它来开发/测试具有特定 WiFi 功能的应用程序。

Currently, while you can use your computer's Internet connection in the emulator, it's not reliable to use it for simulating Wi-Fi. The WifiManagergets confused when you switch/want to test your connectivity state.
目前，虽然您可以在模拟器中使用计算机的 Internet 连接，但将其用于模拟 Wi-Fi 并不可靠。在WifiManager当你切换迷糊/想测试你的连接状态。
Even in Android 1.5, there were some problems with it (Issue 2571 - android), and while you can use your Internet for simulating HTTP connections and downloading data, finer control over Wi-Fi connectivity should better be done with a device.
即使在 Android 1.5 中，它也存在一些问题（问题 2571 - android），虽然您可以使用 Internet 来模拟 HTTP 连接和下载数据，但最好使用设备来更好地控制 Wi-Fi 连接。

Starting from revision 26.1.3, the Android emulator now supports connecting to WiFi on a Nougat image (API 25).
从修订版 26.1.3 开始，Android 模拟器现在支持连接到牛轧糖映像 (API 25) 上的 WiFi。
Added support for Wi-Fi in some system images (currently only API level 25). An access point called "AndroidWifi" is available and Android automatically connects to it.
在某些系统映像中添加了对 Wi-Fi 的支持（目前只有 API 级别 25）。一个名为“AndroidWifi”的接入点可用，Android 会自动连接到它。

You can check the version of your emulator by going into emulator settings (three dots) > Help > About. Also note that if an AVD was created before version 26.1.3 was released, you will have to recreate your AVD. I read somewhere that wiping data might also work, but I did not try that.
您可以通过进入模拟器设置（三个点）> 帮助 > 关于来检查模拟器的版本。另请注意，如果 AVD 是在 26.1.3 版发布之前创建的，则必须重新创建 AVD。我在某处读到擦除数据也可能有效，但我没有尝试过。

If you don't have a real device, I think the best way is installing android-x86or use it on live usb. There is no diffrences between android and android-x86.
如果您没有真机，我认为最好的方法是安装android-x86或在 live usb 上使用它。android 和 android-x86 之间没有区别。
And android-x86 support wi-fi. so you can install your app, and run it.
并且 android-x86 支持 wi-fi。所以你可以安装你的应用程序并运行它。

In theory, linux (the kernel underlying android) has mac80211_hwsimdriver, which simulates WiFi. It can be used to set up several WiFi devices (an acces point, and another WiFi device, and so on), which would make up a WiFi network.
理论上，linux（android底层的内核）有mac80211_hwsim驱动，可以模拟WiFi。它可用于设置多个 WiFi 设备（一个接入点和另一个 WiFi 设备，等等），这将构成一个 WiFi 网络。
It's useful for testing WiFi programs under linux. Possibly, even under user-mode linuxor other isolated virtual "boxes" with linux.
它对于在 linux 下测试 WiFi 程序很有用。可能，即使在用户模式 linux或其他带有 linux 的隔离虚拟“盒子”下。
In theory, this driver could be used for tests in the android systems where you don't have a real WiFi device (or don't want to use it), and also in some kind of android emulators. Perhaps, one can manage to use this driver in android-x86, or--for testing--in android-x86 run in VirtualBox.
理论上，此驱动程序可用于在您没有真正的 WiFi 设备（或不想使用它）的 android 系统中进行测试，也可用于某些类型的 android 模拟器。也许，人们可以设法在 android-x86 中使用这个驱动程序，或者——为了测试——在 VirtualBox 中运行的 android-x86 中。

Probably no substitute for testing on a real device, but if you're looking for a good enough test case in the emulator give Fake Wifi Connectiona try:
可能无法替代在真实设备上的测试，但如果您正在模拟器中寻找足够好的测试用例，请尝试使用Fake Wifi Connection：
It makes apps think they're on wifi no matter what the underlying connection is.
无论底层连接是什么，它都会让应用程序认为它们在 wifi 上。
disclaimer:I wrote this stuff.
It works by intercepting ConnectivityManager / WifiManager calls (uses Xposed). I've tried to cover most of them so it does a pretty good job, nevertheless it's always possible some is missing (if you find something let me know).
免责声明：我写了这个东西。
它通过拦截 ConnectivityManager / WifiManager 调用（使用Xposed）来工作。我试图涵盖其中的大部分，所以它做得很好，但是总是有可能缺少一些（如果你发现了什么让我知道）。
