Making firebase storage public for reading and writing on android

Question

I am new to firebase storage. Can anyone tell me how to make the storage files public for reading and writing?. The default code provided by firebase is given below. What change

Answer 1

// Anyone can read or write to the bucket, even non-users of your app.
// Because it is shared with Google App Engine, this will also make
// files uploaded via GAE public.
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write;
    }
  }
}
