在Android Studio中打开终端，进入../../Android/sdk/tools。'模拟器'可执行文件应该在这里可用。 运行。/emulator -netdelay "delay_in_millis" -avd "emulator_device_name" 例如:./emulator -netdelay 60000 -avd Nexus_5_API_21 现在构建应用程序并将其安装在模拟器中。 在应用程序中运行您的场景。

确保你有你的代码变化在应用程序设置超时你的请求和处理。

你可以使用模拟器。看看这个页面:Android模拟器。请注意下面两个论点:

-netdelay <delay> Set network latency emulation to . Default value is none. See the table in Network Delay Emulation for supported values. -netspeed <speed> Set network speed emulation to . Default value is full. See the table in Network Speed Emulation for supported values. Speeds for reference in increasing kbps: UP DOWN -------- ---------- gsm GSM/CSD 14.4 14.4 hscsd HSCSD 14.4 57.6 gprs GPRS 28.8 57.6 umts UMTS/3G 384.0 384.0 edge EDGE/EGPRS 473.6 473.6 hsdpa HSDPA 5760.0 13,980.0 lte LTE 58,000.0 173,000.0 evdo EVDO 75,000.0 280,000.0 full No limit ∞ ∞

我知道这是个老问题，但是…

现在有些手机的设置是只使用2G。它非常适合在真实设备上模拟慢速互联网。

只需从Android工作室转到Android设备监视器，然后DDMS ->模拟器控件。将有速度和延迟属性。

Facebook建立了一个叫做增强交通控制的东西。GitHub页面上的简要总结:

Augmented Traffic Control (ATC) is a tool to simulate network conditions. It allows controlling the connection that a device has to the internet. Developers can use ATC to test their application across varying network conditions, easily emulating high speed, mobile, and even severely impaired networks. Aspects of the connection that can be controlled include: bandwidth latency packet loss corrupted packets packets ordering In order to be able to shape the network traffic, ATC must be running on a device that routes the traffic and sees the real IP address of the device, like your network gateway for instance. This also allows any devices that route through ATC to be able to shape their traffic. Traffic can be shaped/unshaped using a web interface allowing any devices with a web browser to use ATC without the need for a client application.

你可以在GitHub上找到它:https://github.com/facebook/augmented-traffic-control

他们还为此写了一篇博客:https://code.facebook.com/posts/1561127100804165/augmented-traffic-control-a-tool-to-simulate-network-conditions/

几岁了，但是嘿，我会用Genymotion来配合我的万无一失的方法。

下载Charles免费试用版:http://www.charlesproxy.com/download/ 安装它 ClickProxy ->节流阀设置 设置HTTP节流速度 关闭窗口 单击“Proxy -> Throttling”，开启节流阀 打开Genymotion模拟器 打开wifi设置 长按开启的wifi连接 单击“修改网络” 单击“显示高级选项” 设置代理为手动 设置Proxy主机名为10.0.3.2 端口设置为“8888” 点击保存

现在你的网络将被阻塞!
