Could you share some code

Yes, code would help. Also is that reproducible or was it one time?

Hello, Thanks for your feedback

I'm using this code in my Application class (named: Sky.java) to initialize a BoxStore for using in other classes:
inOnCreate() ---> mBoxStore = MyObjectBox.builder().androidContext(Sky.this).build(); andHaveAMethod ----> public BoxStore getBoxStore() { return mBoxStore; }

Then in SplashActivity.java, app should know that user have(submit) any city object or no, for this, i'm using this code:
int count = ((Sky) getApplicationContext()).getBoxStore().boxFor(City.class).count();

Sometimes everything is good and app runs perfectly, but sometimes, application get force close and stop in this line.

Those code segments look fine and should work perfectly on their own. Are you also doing anything else with transactions or multi-threading?

[ghost]

No, That's all of my code.

I'm experiencing similar bug in numerous places (Enteties) although they are not that common for the users. I'm also using singelton and usally run the db operation on io Scheduler in my Observables.

I'm running v 0.9.9 but saw in the changelog that there were some bugfixes regarding multithreading. Could it be somehow related?

How to avoid this error in the future?

[greenrobot]

Please retest with 0.9.13-RC which fixed some bugs that may be related.

[greenrobot]

@MehranAbi Could you be so kind and retest your issue with 0.9.13? This would really help us. Thanks!

[ghost]

All right, I will test today, and comment the result.

[ghost]

Hooooray, I tested with version 0.9.13 and there is no problem in my app.
Thanks for your nice Library :)

Same here, thanks!
