Questions about using SDK in React Native

[judeProground]

Describe the bug

1. I am trying to use the @metamask/sdk in React Native version 0.68, referencing reactNativeDemo. I successfully built it for Android, but when I try to create a MetaMaskSDK object with the following code, I encounter the following error:

MetaMaskSDK error during initialization [Error: Invalid communication protocol]

2. Additionally, there is a warning as follows. Is there a solution?

   Require cycle: node_modules/react-native-crypto/index.js -> node_modules/react-native-randombytes/index.js -> node_modules/sjcl/sjcl.js -> node_modules/react-native-crypto/index.js

Here's packages I've installed refer to reactNativeDemo

  "dependencies": {
    "@metamask/sdk": "^0.5.3",
    "@react-native-async-storage/async-storage": "^1.18.1",
    "ethers": "5.7.2",
    "node-libs-react-native": "^1.2.1",
    // ... 
    "react-native-background-timer": "^2.4.1",
    "react-native-randombytes": "^3.6.1",
    "react-native-url-polyfill": "^1.3.0"
  },

I apologize for disregarding the template 😅

Hi @judeProground ! Can you please try upgrading the ReactNative version you're using to the one we have in the reactNativeDemo project (0.71.7)? Also, do you also get that warning when building the reactNativeDemo project?

Hi, @christopherferreira9. It seems like I'm encountering an issue possibly due to the React Native version. However, updating current project's RN version might be challenging due to the significant differences in the required changes. For now, I might wait for the metamask-react-native-sdk or explore the option of integrating through WalletConnect. Thank you for the response!

Hi @christopherferreira9 , the metamask-react-native-sdk package is still on hold. The reason why we advise users to use 0.71.7 is because the older versions struggle with slow encryption for the initial key exchange. I'll be closing this issue and in the meantime if you need any other assistance, please open a new one.
