React native fetch api does not work with localhost, IP, or even 10.0.2.2

I am using expo client on my android device and have setup up a django server at localhost:8000 and i'm trying to access and endpoint using fetch in react native. I have looked at How can I access my localhost from my Android device?How do you connect localhost in the Android emulator? and How to connect to my http://localhost web server from Android Emulator in Eclipse but that did not work.

I also tried using my machine's ip address instead of localhost, but no results. Here is a sample code

componentDidMount(){
    return fetch('http://my-ip-address:8000/restapi/')
      .then((response) => {
        console.log("success")
        response = response.json()
      }).catch(error => {
        console.error(error)
      })
  }

What am I doing wrong here?
