Description

The react-native-auth0 Expo config plugin is intended to be able to set up Android App Links, but following the instructions to configure it the App Link URL shows in the web browser instead of redirecting back to the app.

Reproduction

• Clone https://github.com/CodingItWrong/auth0-react-native-sample/tree/jjustice/android-app-links
• Configure an Auth0 tenant that is set up for Android App Links
• Run the app and sign in
• Expected: able to sign in
• Actual: redirect URL shows in the web browser instead

Additional context

I was able to get login working by using the following custom Expo config plugin instead of the official react-native-auth0 Expo config plugin. My custom plugin configures manifest placeholders. As I understand it, though, this shouldn't be necessary:

const { withAppBuildGradle } = require("expo/config-plugins")

const withAuth0 = (config, options) => {
  config = withCustomAppBuildGradle(config, options)
  return config
}

const withCustomAppBuildGradle = (config, options) => {
  return withAppBuildGradle(config, (config) => {
    // Add the manifestPlaceholders to support our app link
    // https://github.com/auth0/react-native-auth0?tab=readme-ov-file#android-1
    config.modResults.contents = config.modResults.contents.replace(
      `minSdkVersion rootProject.ext.minSdkVersion`,
      `manifestPlaceholders = [auth0Domain: "${options.domain}", auth0Scheme: "https"]
          minSdkVersion rootProject.ext.minSdkVersion`,
    )

    return config
  })
}

module.exports = withAuth0

You can try this and see it work in the repro by replacing the "react-native-auth0" plugin with "./withAuth0.js". Video:

@CodingItWrong If I read correctly you have this bug on 5.0.0-beta-3.
But the fix is in release 5 #1328

So is bug already exist on v5?

@multivoltage we haven't yet gotten to update our app to the full release of 5.0.0 to test that the fix is working there
