你试过这个吗? 设置—网络—更多—移动网络—网络模式—选择首选网络(以2G网络为例)。

上面提到了我使用的另一种方法。通过iPhone热点连接。 希望这能有所帮助。

或者在一个实际的设备上，你可以去设置->移动网络->首选的网络类型，并选择可用的最慢的… 当然，这是非常有限的，但对于某些测试目的，这可能足够了。

我发现netlimiter4是将数据节流到模拟器的最佳解决方案。 它通过体面的gui提供粒度控制，并为每个进程的数据吞吐量提供图形化反馈。目前处于免费测试版。 截图

在游戏商店中有一些应用程序可以节流到实际设备上，但它们需要root(我不能提供任何关于它们工作得如何的建议，如果在所有- YMMV)。

在游戏商店搜索bradybound，我不能发布超过一个链接。

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 ∞ ∞

运行>运行配置，选择Android应用程序，然后进入目标选项卡。按照图中所示进行更改。

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/
