Answer 1

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'

Answer 2

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.`'
    }
}
