You are using old versions of these

implementation 'com.google.android.gms:play-services-location:9.4.0'
implementation 'com.google.android.gms:play-services-maps:9.4.0'

try these newer versions 

implementation 'com.google.android.gms:play-services-location:16.0.0'
implementation 'com.google.android.gms:play-services-maps:16.1.0'

In the app's "build.gradle" file, add the following along with "android {...}"

configurations.all {
    resolutionStrategy {
        force 'com.google.android.gms:play-services-basement:16.0.`'
    }
}

Such errors are easily resolved by bumping the version of your libraries to the latest ones.

I can see that you're using super outdated versions of following libraries:

implementation 'com.google.android.gms:play-services-location:9.4.0'
implementation 'com.google.android.gms:play-services-maps:9.4.0'

Bump up their versions, and versions of all the other libraries and that should fix the error.

Latest version of both the libraries is 16.0.0, so you should make it

implementation 'com.google.android.gms:play-services-location:16.0.0'
implementation 'com.google.android.gms:play-services-maps:16.0.0'

If after you updated your libraries as previous users have suggested, you keep seeing the same error, try excluding the duplicate module from one of your libraries. For example:

implementation 'com.google.android.gms:play-services-location:16.0.0'
implementation 'com.google.android.gms:play-services-maps:16.1.0'{
        exclude group : 'nameOfTheGroupHere', module: 'nameOfTheModuleHere'
    }
