[OnlineStateTracker]: Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds

[John Hansen]

Hi, I'm trying to use Cloud Firestore in my Android app.

I have a fairly simple database structure e.g. /database/users/user/(some attributes)

And, I populated it in the console w/ some data.

In my Android App, I'm having trouble doing a simple read of the database and getting: "[OnlineStateTracker]: Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds"

My read code is just like the Firestore samples:

val docRef = database.collection(USERS).document(uid)

                docRef.get().addOnSuccessListener {doc ->

                    doc?.let {

                        PLog.i(TAG, "updatePortfolioFromFirestore: doc: ${doc.data}")

                    }

                }.addOnFailureListener {

                    PLog.i(TAG, "updatePortfolioFromFirestore: exception: ${it.localizedMessage}")

                }

Execution never returns with the doc data.

There is nothing wrong with my WiFi or the device and I've tried the code on multiple devices and the Emulator - same problem.

I've turned on FirebaseFirestore.setLoggingEnabled(true) but don't see anything useful in that log output.

I built a small program with another database just to try and reproduce but its working fine.

I checked the build.gradle files between my small sample project and the target and they are all same and fine.

What else can I do to debug this? Any help appreciated. Thanks.
