Manifest merger failed : Attribute data@scheme at AndroidManifest.xml requires a placeholder substitution but no value for is provided.

What is this error? how to solve it? Cheers

In the app build.gradle, navigate to the defaultConfig section and add the following line.

Source Code

   defaultConfig {
    ...
    manifestPlaceholders = [appAuthRedirectScheme: 'com.redirectScheme.comm']
}

And funnily enough, the value you provide doesn't matter. I fixed my project with the following line. Go figure!!! manifestPlaceholders = ['appAuthRedirectScheme': 'YOURSCHEME'] – eva Jul 17 '22 at 22:49
Yeah right, that works. – Bello Damilola Jun 07 '23 at 13:18

Try to add manifestPlaceholders

https://github.com/FormidableLabs/react-native-app-auth#add-redirect-scheme-manifest-placeholder

android {
  defaultConfig {
    manifestPlaceholders = [
      appAuthRedirectScheme: 'io.identityserver.demo'
    ]
  }
}

I hade placed my api key in Gradle Script directory local.properties file and received the same error when I used the key in Manifest meta-data tag. The following solved it:
In build.gradle Project file add:

id 'com.google.android.libraries.mapsplatform.secrets-gradle-plugin' version '2.0.0' apply false

In build.gradle Module file add:

id 'com.google.android.libraries.mapsplatform.secrets-gradle-plugin'
