你也可以在真正的android设备上测试慢速互联网连接:

在三星Galaxy S8 + Android 8.0.0上测试

进入设置->连接->移动网络->，在网络模式下，你可以选择只使用2G或3G连接

我很惊讶没人提到这一点。你可以通过蓝牙连接，并将它们分开十多米(或更少的障碍物)。你的信号很差。没有微波炉，没有电梯，不需要软件。

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 ∞ ∞

Android工作室AVD更新:

开放式AVD管理器 创建/编辑AVD 点击高级设置 选择您首选的连接设置

没有微波炉和电梯:)

我需要在AndroidTV本机设备上限制低网络，根据我所读到的，最合适的解决方案是直接在我的路由器上限制互联网访问。 进入路由器设置(本地是smth，如192.168.0.1)->设置DHCP服务器(如果没有运行)->选择设备的IP地址并设置限制;

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.

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/
