Android Working?

[brianegan]

Hey there! I've tried Firebase 3.2.0 on Android in my own react native project and I seem to be running into trouble!

I've setup my config, initialized the app, and then tried logging in anonymously and with emailAndPassword like so:

firebaseApp.auth().signInAnonymously()
      .then(function onSignInSuccess() {
        console.log("success", arguments)
      })
      .catch(function onSignInError() {
        console.log("Failure", arguments)
      })

The problem: On iOS, the promise succeeds or fails as expected, whereas on Android the Promise does not. Any ideas on why or why 3.2.0 might not work for Android yet works fine on iOS? Is RN for Android supported?

@brianegan I am facing the same issue as you.

let connectedRef = firebaseRef.database().ref(".info/connected");
connectedRef.on("value", function(snap) {
  if (snap.val() === true) {
    console.log("connected");
  } else {
    console.log("not connected");
  }
});

This always displays not connected on Android. While it works just fine on iOS. @davideast is this a regression in 3.2?

@brianegan @davideast I figured out the issue. It seems like the firebase is not compatible with the latest 0.31.0 release of react-native. I used 0.30.0 and it seems to work fine.

If someone is curious, it seems that scoping is the issue here. For reference look at: wkh237/react-native-fetch-blob#93

@brianegan @shilpan can I suggest using react-native-firebase - it's a small JS bridge to native side - no fetch used as all the work is done by the official native firebase SDK's for android and IOS.

It's much faster and doesn't reduce the JS frame rate. It also includes storage, crash reporting, analytics and offline capabilities compared to the web SDK.
