title: Proxy address not working in react-native client
body: <p>I'm trying to make a GET API request in my first react-native app(expo project, running it on my physical android device).
  I'm seeing trouble while trying to make a get request using Axios - I have my backend in express connecting to Firebase DB.
  {The below setup works fine in react web app}</p>
  
  <pre><code>  ... 
    const handleSubmit = () =&gt; {
      const userData = {
        email: email,
        password: password
      };
      axios.get('/alltests')
        .then((res) =&gt; {
          alert("Successfully loggedin", res)
          console.log(JSON.stringify(res.data))
        })
        .catch((err) =&gt; {
          console.log("\n\nI'm in error block - frontend")
          console.log(err)
          alert(err);
          //setErrors(err.response.data)
        })
       ...
  </code></pre>
  
  <p>My package.json looks like -> </p>
  
  <pre><code>  "dependencies": {
      "@material-ui/core": "^4.8.1",
      "@material-ui/icons": "^4.5.1",
      "axios": "^0.19.0",

    },
    "private": true,
    "proxy": "https://asia-something.net/api"
  }
  
  </code></pre>
  
  <p>However, if I use 
  axios.get('<a href="https://asia-something.net/api/alltests" rel="nofollow noreferrer">https://asia-something.net/api/alltests</a>')
  this seems to be working in the code. </p>
  
  <p>I'm not using localhost or running the backend on local server.
  Can someone help me here, please?</p>
