"Invariant failed" - help with error solving

[yaronkoresh]

Hello!
I am a beginner in the subject of apk development, so your help will be much appreciated.
I started a few days ago with expo, but I can’t manage to solve that specific error:
“Invariant failed (Device)”
Here is the code
Here is the barcode for Expo Go
Its should be a template that I will change it according to the apk i will need.

Hi @yaronkoresh

I tried running it on an Android device:

Just based on the error it looks like there’s some web browser-specific code that’s trying to run in the Expo Go app. This won’t work because React Native isn’t a web browser, so the createBrowserHistory call fails.

By the way, your package.json on GitHub is incomplete. It looks like what you see in a Snack, but Snack doesn’t show you everything that should be there. If you Export the project from Snack you’ll see it fills in the rest of the stuff that should be there.

If I export the snack, run yarn to install the dependencies and then search for createBrowserHistory I find this:

coding % grep -rl createBrowserHistory .

So it’s coming from react-router and react-router-dom. These are not compatible with React Native. Try something like React Navigation instead.

@wodin
The problem were those react-router imports, as you said.
I have other errors so I’ll keep working on it.
Many thanks!
