Android Studio HTTP Proxy

Introduction

Android Studio is a popular integrated development environment (IDE) used for developing Android applications. It provides developers with a wide range of tools and features to streamline the development process. One important feature is the ability to configure an HTTP proxy, which allows developers to access the internet through a proxy server. In this article, we will explore how to configure the HTTP proxy settings in Android Studio and provide some code examples.

Configuring HTTP Proxy Settings in Android Studio

To configure the HTTP proxy settings in Android Studio, follow the steps below:

1. Open Android Studio and go to File -> Settings.
2. In the Settings window, expand the Appearance & Behavior section and click on System Settings.
3. Under the HTTP Proxy section, select the Manual proxy configuration option.
4. Enter the proxy server address and port number in the corresponding fields.
5. If required, enter the proxy server username and password.
6. Click on the Test Connection button to verify the proxy settings.
7. Once the settings are configured, click on the Apply and OK buttons to save the changes.

Code Examples

To demonstrate how to use an HTTP proxy in Android Studio, let's create a simple application that retrieves data from a remote server using the HTTP protocol.

Here is the code snippet:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.Proxy;
import java.net.URL;

public class ProxyExample {
    public static void main(String[] args) {
        try {
            // Create a URL object for the desired endpoint
            URL url = new URL("

            // Create a proxy object using the proxy server address and port
            Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxy.example.com", 8080));

            // Open a connection to the URL using the proxy
            HttpURLConnection connection = (HttpURLConnection) url.openConnection(proxy);

            // Set the request method to GET
            connection.setRequestMethod("GET");

            // Read the response from the server
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            StringBuilder response = new StringBuilder();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();

            // Print the response
            System.out.println(response.toString());

            // Close the connection
            connection.disconnect();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

In the above code, we create a URL object for the desired endpoint, create a Proxy object using the proxy server address and port, and open a connection to the URL using the proxy. We then set the request method to GET, read the response from the server, and print it to the console. Finally, we close the connection.

Sequence Diagram

The following sequence diagram illustrates the steps involved in making an HTTP request through a proxy server:

    participant Client

    Client->>Proxy: Create Proxy Object
    Client->>Proxy: Open Connection to URL using Proxy
    Proxy->>Server: Send HTTP Request
    Server->>Proxy: Send HTTP Response
    Proxy->>Client: Send HTTP Response
    Client->>Client: Process Response

Conclusion

Configuring an HTTP proxy in Android Studio is a straightforward process. By following the steps mentioned above, developers can easily set up a proxy server to access the internet. Additionally, we explored a code example that demonstrates how to use an HTTP proxy in an Android application. Understanding and utilizing HTTP proxies can be beneficial in scenarios where internet access needs to be routed through a specific server.
