Gradle “manifest requires a placeholder substitution” error but manifestPlaceholders supplies a value

Question

I\'m trying to perform substitution within the AndroidManifest.xml file from the build.gradle android extension but am getting this error:

AndroidManifest.xm         


        

Answer 1

You need to add the applicationId placeholder to the application gradle. This happens with the integration of Firebase, after updating to Gradle 2.2.0-alpha1

android {
    ...
    defaultConfig {
        applicationId "com.example.my.app"
        ...
    }
}
