Error on android build

[hakankozakli]

First of all, Great work! Thanks a lot.

When I try to build for android I am getting this error:

* What went wrong:
Could not determine the dependencies of task ':app:preDebugBuild'.
> The library com.google.android.gms:play-services-vision-common is being requested by various other libraries at [[19.1.0,19.1.0], [19.0.2,19.0.2]], but resolves to 19.1.0. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.

Then I try to bypass it with
com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true
but then it throws this error:

* What went wrong:
Execution failed for task ':app:checkDebugDuplicateClasses'.
