React-native Axios is working in iOS but not calling in Android

Question

I can't seem to get the following Axios call to work on Android. It's not hitting the server and showing the error : [Error: Network Error]. The same code works on iOS. Do I have to do something special to enable network requests for Android on React Native?

 var url = 'https://***.****.com/api/list';
 axios.get(url, 
           { headers: {'Content-Type': 'application/json'}}
          ).then((response) => {
               console.log("response = ",response.data)
          })
          .catch((error) => {
              console.log("error = ", error)
          });

I got this error in console :

error = >  Error: Network Error

    at XMLHttpRequest.handleError (index.bundle?platfor…minify=false:117857)

Answer 1

Both iOS and Android have worked for me in the past. A basic skeleton I use is first initiating an axios object with a helper file:

// test_api.js
import axios from 'axios';

export default axios.create({
  baseURL: 'https://***.****.com/api/list',
  headers: {'Content-Type': 'application/json'}
});

...then in the file pulling data:

// app.js
import test_api from './test_api';

const request = async () => {
  try {
    const response = await test_api.get('/');
    console.log("response = ", response.data)
  } catch (error) {
    console.log("error = ", error)
  };

Hope this helps.

it could be your error is like this issue: https://stackoverflow.com/a/16302527/7714108

You need to get on deeper in your Error object, if you get

javax.net.ssl.SSLHandshakeException:
java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

your error is about misconfigured server.

I have this problem on Android 6.0 - API 23 (Marsmallow) and earlier. I don't know why happen only to me from those api and earlier. I am using Expo sdk 35, and I tried with axios, fetch and XMLHttpRequest, and the error always is pretty similar "Network Error". But apart of that, for debugging I am using React Native Debugger, then my curiosity is about why when I enable Network Inspect, this error is gone.

Please don't use "axios" instead of this use "fetch". it will work for both iOS and android here is the example code for fetch data.

  Test = async ()=>
    {
      try
      {
     fetch(
          'your url', 
          {
          method: 'POST',
           headers: {
        Accept: 'application/json',
        'Content-Type': 'application/json',
      },
          body: JSON.stringify({
             firstParam: 'yourValue',
        secondParam: 'yourOtherValue',

          })
        }).then(response => {
          const statusCode = response.status;
          const data = response.json();
          return Promise.all([statusCode, data]);
        })
        .then((res) => {
          if (res[0] == 200 && res[2].request_results.result_header.code == 100)
          {

          }
    }
        }).catch((error) =>
          {
            console.error(error);
          }
        );
        }
      }
      catch (e)
      {

      }

      };

you will get your data in "res" and can extract by using for-loop or something else logic that you want to apply.
