Expo 26 - pb with android - attempt to invoke virtual methode int java.lang.String.hashCode() on a null object

#1

Hi,

I updated from expo 25 to 26.
I have an app. On IOS it’s still work just fine.
But I have an error on my android device when I’m trying to login :
‘Attempt to invoke virtual method ‘int java.lang.String.hasCode()’ on a null object reference’

Does anyone know what can I do ?

Thanks

Hard to say without more context about where it’s being thrown and why. Maybe Android is catching an underlaying error that it used to ignore :woman_shrugging: Is this being invoked from any particular API?

I got this after upgrade to expo 26. Seems to be related to marker images for maps. I only get this for android standalone build:

You can test how the app will run in prod by running exp start --no-dev --minify this should surface better errors for you
