What is the default timeout for HttpURLConnection under Android?

A - Documentation

Due to the documentation of Java of the HttpURLConnection, timeout is set to 0 (which means infinity) by default and can be modified.

Specifically, it is written in the accessor/getter method in the documentation;

public int getConnectTimeout() Returns setting for connect timeout. 0 return implies that the option is disabled (i.e., timeout of infinity).

Returns: an int that indicates the connect timeout value in milliseconds Since: 1.5 See Also: setConnectTimeout(int), connect()

If I were you, I would set the connection timeout before starting the connection and set my logic/flow based on my own initial values. Below, you can see an example for how to get the default value and set/modify the connection timeout parameter.

B - Example Code

package com.levo.so.huc;

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;

public class HttpConnectionTimeoutDemo {

    public static void main(String[] args) throws IOException {
        String url = "http://www.google.com/";

        URL obj = new URL(url);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();
        
        System.out.println("Default Connection Timeout : " + con.getConnectTimeout());
        
        con.setConnectTimeout(1000);
        System.out.println("New Connection Timeout     : " + con.getConnectTimeout());

    }

}

C - Output

Default Connection Timeout : 0
New Connection Timeout     : 1000
