Hey, @gen did you get a chance to check the sample app. I really waiting for your reply to go ahead.

Hi @dev.karmaln yes I’ve checked your code, we are currently improving the codebase that will also address some known issues like signing popup not showing with android that might also fix what you are currently experiencing. I do apologize for the inconvenience, I will get back to you as soon as possible.

Hello, I was using react native boilerplate, I’m able to log in but when I tried to call enableWeb3() in one of my components and I reviewed isWeb3Enabled value after that is returning false, do you have any suggestions about it? I would really appreciate your help, we want to create a mobile app for the hackaton and this is blocking us for the moment

Thanks, Jose

I am trying to debug the ethereum-react-native boilerplate using localhost:8081/debugger-ui but I keep getting the following exception which is preventing me from viewing source code and adding breakpoints:

Error: EISDIR: illegal operation on a directory, read

What can be done to resolve this so that I can debug the app besides using breakpoints?

Now I have the app opended but when I click authenticate , it doesn’t show the popup of all the wallets on wallet connect but It just opens the browser on my phone

meankasa · December 10, 2021, 6:09pm

I’m facing the same issue

cwong · December 11, 2021, 7:24pm

I am also facing the same issue

Jackson · December 12, 2021, 1:07pm

Please how can I get this boilerplate to work in expo

justinride · December 12, 2021, 4:35pm

aha Its looking good might work now that’s set up the comand line tools location in xcode using this that I got from a web search

justinride · December 12, 2021, 4:50pm

aha no worries the Quick Start github instructions actually worked for me! Thanks https://youtu.be/9-hF16_6tkk

cwong · December 13, 2021, 10:52pm

I was able to fix the issue with this code.

malik · December 14, 2021, 1:47am

Hi @Jackson ,

We are trying to remove expo integration from the boilerplate as it has a lot of unexpected issues. Please follow the steps laid down in the GitHub description to run the app instead.

@meankasa, adding the code as shown by @cwong should solve the issue.

@justinride, keep up the great work!

@meankasa @cwong Some devices in android are not able to connect with the wallets directly. This has been reported to walletconnect and we are trying to figure out why this happens.

I managed to solve this problem on the emulator, but on the real phone it remained

Jackson · December 14, 2021, 3:14pm

okay sir thank you, i also got issues when running the app on a physical and emulator, the issue is that once finished loading all the 10 account with 1000ETH each, the app never build on my phone

malik · December 15, 2021, 2:37am

Did you follow the steps that were laid out in the github readme?
Running yarn android does not work.

Try -
Android:

Command yarn start
Open android folder from source code in Android Studio. Click “Run app” button to open either emulator or physical device. To see if devices are available, run command adb devices in your terminal.

iPictorial · December 15, 2021, 10:16pm

I’m facing the same issue in browser I see 404 error.

malik · December 16, 2021, 5:03am

As mentioned above, it is an issue from Walletconnect and we are looking into it.

Confirmation window not opening in meta mask wallet.
I tried to call a payable contract function. On clicking the button the metamask app is opening, but the confirmation window is not.
