Firebase-android-sdk: Firebase RealTime Database Socket connection error

Created on 11 Nov 2018 · 8Comments · Source: firebase/firebase-android-sdk

I am using fireabse real time database for my application. At times it it unable to form socket connection. But requests made to API hosted on firebase cloud-fucntion works properly.
I have used following dependencies :-

    implementation 'com.google.firebase:firebase-core:16.0.4'
    implementation 'com.google.firebase:firebase-database:16.0.3'
    implementation 'com.google.firebase:firebase-storage:16.0.3'
    implementation 'com.google.firebase:firebase-auth:16.0.4'

When I turned on the debug level it gives following :-

2018-11-11 14:13:17.932 14446-14513/com.example.com D/ConnectionRetryHelper: Scheduling retry in 933ms

2018-11-11 14:13:48.882 14446-14513/com.example.com D/Connection: conn_1 - closing realtime connection

This keeps happening on certain device like Mi5 note pro, lenov

Getting the same error on Firebase Realtime database 16.1.0, it doesn't work on mobile network, but works perfectly fine on WiFi networks, also is much likely to happen on a device running Android 9.

The same snippet of message occurs in a loop.

Issues like this in the past were device-specific problems with the local network stack. For debugging, we would need you to try to manually connect to the Firebase Host (which is specified in your google-services.json).

Since this issue has gone stale (sorry about that!), I am closing it for now. Let us know if it still persists.

I am still getting this issue in Android. I am using following libraries.
implementation 'com.firebase:firebase-client-android:2.5.2'
implementation "com.google.firebase:firebase-database:16.1.0"
implementation "com.google.firebase:firebase-auth:16.1.0"

with custom Auth. https://firebase.google.com/docs/auth/android/custom-auth

@anujjindal77 don't use implementation 'com.firebase:firebase-client-android:2.5.2' that's an extremely old library from pre-Google Firebase days!

Still facing this issue!!

I am facing the exact same issue. I am using Firebase Real-time database 16.1.0. As far as I have observed this occurs on some devices when they are on mobile data. This issue is creating a lot of issues in the app.
