Hi,
How can I fix app crashes when firebase updates?
Thanks.
- how does the app crash ?
- what does your firebase strcuture look like in the firebase console ?
- do you have any secure rules in place?
I have already made some apps following the same procedure both for the creation of the Firebase DB and for the app blocks...
It seems, but not always, that the problem occurs with the DataChanged event... both if I change the Tag value from the app and if I change it from the Firebase console...
I do not have any security rules set....
and again ?
the app closes..
and then i have to reopen it...
could this be the area chosen for the server?
Possibly, The Firebase component will only work with the us-central server.
how can i check the server location... i dont remember when i created it...
Should be showing on your firebase console page
This is location: LocalitĂ del database: (us-central1) - Stati Uniti
so it shouldn't depend on the location...
Any solutions....?
Use logcat to find out what's going on

this is what happens... as I start the app it closes!
You are not showing us all your relevant blocks, especially those at start up.

yes sorry this was the log of the final app but I have the same problem with the blocks I attached...
anyway a strange thing:
if I use the projectBucket: 00000 the error occurs
with the other tags no....
I deleted the projectBucket 00000 from the firebase console, then I recreated it with the app and now it doesn't crash....
