Android dependency '..' has different version for the compile (..) and runtime (..) classpath

Question

I migrated to Android Studio 3 and Gradle 4. Then I changed compile to implementation in my build.gradle files. But I get the error:

Answer 1

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

put this code in your project gradle
