Error when building app for Android

[luccascorrea]

When I try to run the app, I get the following messages:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:preDebugBuild'.
> Android dependency 'com.google.android.gms:play-services-base' has different version for the compile (11.8.0) and runtime (15.0.1) classpath. You should manually set the same version via DependencyResolution

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

* Get more help at https://help.gradle.org

BUILD FAILED in 1s
Finished with error: Gradle build failed: 1

I saw here that, in order to fix this, all you have to do is change the GMS dependency from "implementation" to "api" in the library's build.gradle file.

I did it and it worked. I am just posting this issue to let you guys know so that someone can fix it. Thanks.
