My app when installed isn't working. Please help me

Hi all,

I just downloaded my APK file which I received through email.
It works fine in thunkable live.
Also, I downloaded the app a few days ago and it worked perfectly fine. I just made a few updates today and download it again. But now, it says “There has been a critical error”…and such…

I don’t know what to do… someone please help me…
I’m really worried right now.
I have to submit this today…

Please help me.
I’m desperate.

Can you show us your blocks and the error message?

I’ll take a wild guess - are you using stored variables? If so, are you checking if they’re null before trying to use them?

@lukehoogenboom0i,

I’ll give you guys my thunkable link.

And the error message is shown when I click the button “Add Income”.

It shows the same error when I click the “Add Expense” button.

i am unble to see the problem and test because the firebase tokens are set to empty.

Add those tokens and test again maybe that’s the problem.

@luvcoding_aish ,
So it crashes when you should go to add income screen sub main? Immediately, not after a button click on that other screen?

Sorry @catsarisky i don’t really get what your saying.
Can you explain a bit further?

It’s you who needs to explain further. Tell us precisely when the crash occurs.

It is not a crash i can’t test the app When it uses firebase with empty tokens.
Its the sign in screen.

Uh, luke? I was responding to the original poster, who reports a crash!

Thank you all for all your help!!!

It turns out to be a minor mistake of mine that caused the crash…

I gave “null” in an initialize variable block…instead of an empty string…
Many thanks to all who spent time to help me!!
(& sorry too)
