Thanks,

Do you get any errors? This seems like an emulator issue, try restarting everything or try using another.

Thanks, for answering, I restarted and it started.
However, now I am getting some errors:

  1. Non ethereum enabled browser.
  2. When I click on Crypto Wallet Login it takes e to WalletConnect 404 -This page could not be found.
  3. When I return to Login page I get another error: Possible Unhandled Promise Rejection.
  4. When I want to login is not directing to MetaMask app (like in the tutorial) but to WalletConnect (error 1 above).

Can you try cloning the finished project here and running it? Just to make sure you didn’t miss any steps when following the tutorial.

Thanks, I will do that.

I got it running. The problem was solved on a physical devise after I installed MetaMask.

Great. Any idea what the issue/fix was? In case someone else has a similar issue.

#9

There was no problem except that I did not have installed any wallet in my device and thus I could not login. After I installed MetaMask it worked.

I wanted to test it on 2 devices but when I installed the apk on another physical device I get this message:

Release APK: Unable to load script. Make sure you’re either running a Metro server (run ‘react-native start’) or that your bundle ‘index.android.bundle’ is packaged correctly for release.

Android failed to load JS bundle. How could I fix this?

#10

Can you look at these threads for anything that might help? Since it’s a physical device and looking at the error, the possible causes that stand out are if your phone has access to the Metro server or if the APK is a proper build.

Yes, I solved it by running react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

Thanks :star_struck:

A question: 2 people got the app, they write mesages (I see them in Moralis server) but none of them see what the other one writes. How to write to each other? :grinning: :laughing:

#13

Not sure what you mean by messages specifically (how it’s implemented). If this data is stored in your database you can query for it to display in your app.

#14

Is ok, running the chat perfectly.
Can we create groups in this chat app?
