Error: Manifest merger failed

I got an error

Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute data@scheme at AndroidManifest.xml requires a placeholder substitution but no value for <appAuthRedirectScheme> is provided.

How to solve this?

Hi ,

You need to mention your App Auth Redirect Scheme in App’s build.gradle file. Below is example from my code.

android.defaultConfig.manifestPlaceholders = [‘appAuthRedirectScheme’: ‘YOURSCHEME’]

YOUR SCHEME is same value as in Manifest file RedirectUriReceiverActivity.

<activity android:name="net.openid.appauth.RedirectUriReceiverActivity"> <intent-filter> <action android:name="android.intent.action.VIEW"/> <category android:name="android.intent.category.DEFAULT"/> <category android:name="android.intent.category.BROWSABLE"/> <data android:scheme="YOURSCHEME" /> </intent-filter> </activity>

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

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