Using exactly same configuration but still get "Configurations cannot be different" error

hkchakladar · 2023-11-22T18:43:10.598Z

I’m using this code to get Realm Instance on MainActivity:

App app = new App(new AppConfiguration.Builder("application-0-vaocb").build());
SyncConfiguration config = new SyncConfiguration.Builder(app.currentUser()).build();
Realm realm = Realm.getInstance(config);

And using the exact same code on another activity CustomerActivity:

App app = new App(new AppConfiguration.Builder("application-0-vaocb").build());
SyncConfiguration config = new SyncConfiguration.Builder(app.currentUser()).build();
Realm realm = Realm.getInstance(config);

Still getting this error:

java.lang.IllegalArgumentException: Configurations cannot be different if used to open the same file.

Hi @hkchakladar,

Have you tried to not re-declare the app, but just re-use the same, kept as global? Having a different app, hence a different currentUser() object, may be the issue here.

hkchakladar · 2023-11-23T13:59:31.823Z

Hi @Paolo_Manna ,

How to do that?

Jason_Whetton · 2023-11-24T12:02:02.580Z

It looks like the error handler registration counts towards the hash of the configuration. Try removing the error handler…

Hi @Jason_Whetton , I have not registered any Error handlers.

Is problem solved? I am doubt can i ask a question?

Sajjad_Amini · 2023-12-20T16:01:49.842Z

Hi @Sajjad_Amini and @Arturo_Martinez ,

Arturo_Martinez:

We don’t know whether the problem in the description was solved, as the OP never replied to our suggestion (i.e. only use ONE app, don’t re-create the app every time you try to access the DB, as that can leave around multiple users that would conflict when accessing the same DB)

Hi @Sajjad_Amini
have you been able to resolve the issue?

Jason_Whetton:

error handler

I am using ONE app and not recreating it. Still facing the same error. Can you please suggest me other solution?

Hi @hkchakladar
I am facing this issue. Have you been able to find out what is the problem and how to fix it?
