Firebase Database: Save/Retrieve Offline Data

Hi there,

I want to use Firebase to update my content (text) on my mobile app.

What is working so far
I can see direct changes on the mobile, from the the Firebase Database, when there is an internet connection at least at the start of the app.

Problem
When the app starts offline, there are no "offline" data available.

Idea
Is there a way to save the Firebase as JSON locally and let this file auto update if there is an internet connection? I want to keep it very simple and just fetch new data, if there is a connection and changes - otherwise use local/current data.

Thanks and Cheers

 

Ok, I found a solution:

Code (CSharp):

1.        
2. FirebaseDatabase.DefaultInstance
3.             .RootReference
4.             .GetValueAsync ()
5.             .ContinueWith (task => {
6.             DataSnapshot snapshot = task.Result;
7.                string JSONfile = saveToJSON(snapshot.GetRawJsonValue());
8. });

 

Hi @EchtMe

How were you able to catch the fault of the task. I am finding it difficult to detect when the task fails if offline.

 

I manage to solve this by adding this code during the start of your app.

Code (CSharp):

1. FirebaseDatabase.DefaultInstance.SetPersistenceEnabled(true);

It works fine in iOS and in Editor, however I have problem working it in Android.
