回答1:

In your build.gradle - in end -After -

task clean(type: Delete) {
  delete rootProject.buildDir
 }

add -

 subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "26.1.0"
            }
        }
    }
}

I found I got the same error when I include flutter_downloader, remove that, the error gone.

Android dependency 'android.arch.core:runtime' has different version for the compile (1.1.0) and runtime (1.1.1) classpath. You should manually set the same version via DependencyResolution
