Setting up a network proxy in Android: Detailed explanation in one article

introduction

On mobile devices, especially the Android platform, setting up a network proxy is a common requirement, and network requests and responses can be intercepted and modified through the network proxy. This article will introduce in detail the method of setting a global HTTP proxy through the adb command on Android devices, and explain the practical use of this operation and its application scenarios in development and testing.

How to set global HTTP proxy in Android

On Android devices, a global HTTP proxy can be set through the adb command line tool, which is a convenient and powerful tool for developers and testers. The following is an example command to set a global HTTP proxy through adb:

adb shell settings put global http_proxy ip:port
adb shell settings put global http_proxy :0

Among them,ip:port represents the IP address and port number of the HTTP proxy server you want to use. If you want to disable the proxy, you can pass :0 as a parameter.

the real function

1. Network debugging and packet capture

By setting a global HTTP proxy, developers can use packet capture tools (such as Charles, Fiddler, etc.) to capture network requests and responses on Android devices. This is very helpful for debugging your application's network requests, viewing interface return data, and detecting potential network issues.

2. Simulate network conditions

During development and testing, it is crucial to simulate different network conditions. By setting a global HTTP proxy, network tools can be used to simulate different network conditions, such as weak network connections, high latency, or disconnected states, to ensure that the application can work properly under various network conditions.

3. Security Test

Network proxies can also be used to conduct security testing and simulate network security issues such as man-in-the-middle attacks. By capturing and modifying network traffic, you can evaluate how your application performs in the face of potential security risks and take necessary security measures.

Sample demonstration

The following is a simple Python example that demonstrates how to use thesubprocess library to automate adb commands through a Python script to set a global HTTP proxy:

import subprocess

def set_global_proxy(ip, port):
    command = f'adb shell settings put global http_proxy {
      
      ip}:{
      
      port}'
    subprocess.run(command, shell=True)

def disable_proxy():
    command = 'adb shell settings put global http_proxy :0'
    subprocess.run(command, shell=True)

# 示例:设置代理
set_global_proxy('192.168.1.100', '8888')

# 示例:禁用代理
disable_proxy()

in conclusion

Setting a global HTTP proxy on Android devices is a powerful operation that provides developers and testers with the ability to debug and test applications under different network conditions. In this way, you can better understand the performance and security of your application in various network environments. However, it should be noted that agents should be used with caution in actual use to avoid unnecessary problems.
