[pmadruga]

Does it happen every time?

[prescindivel]

this error also happened to me

[pmadruga]

I'm not able to replicate this with a new RN project? Was that the case?

[tolgaberk]

is there any solution? it just happened to me.

(edit) i was just in the android dir thats why it thrown an error.

[pmadruga]

So this error happens when you're in the android directory? I'll give it a try tonight.

Tried it after upgrading to RN 0.64.1. Had the same error as mentioned above. Ran yarn, retried cleaning and it worked.

This is because you have removed your node_modules directory and your build.gradle file requires a resource in order to load your project and then clean your project.

Hello,

I'm experiencing the same issue (React Native version is 0.63.4). @iamandiradu solution didn't work although I didn't yet update version.

Have a nice day.

[MaganAnkur]

I am experiencing the same issue with 0.66

Closing because the discussion has been moved to #79 . I've also released a potential fix - please check that thread. Thanks.
