Android build error "AndroidManifest.xml requires a placeholder substitution"

Question

I'm building a reactNative app for Android, and I'm getting this error:

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

What is this error? how to solve it? Cheers

Answer 1

in the

app build.gradle

android {
compileSdkVersion 26
buildToolsVersion '26.0.3'

defaultConfig {
    applicationId "com.chuchas.comm"
    ...

    // place correct redirectScheme~
    manifestPlaceholders = [appAuthRedirectScheme: 'com.redirectScheme.comm']

}
