When building apk using Proguard, I see theses Warnings:

I'm using Google Play Services 10.2.0, modules ads, ads-lite, analytics, analytics-impl, base, basement, drive, games, tasks.
What modules or libraries need to be included to fix those warnings?

Based from this thread, if you use ProGuard, you need to keep some GMS (Google Play Services) classes and they are annotated with @com.google.android.gms.common.annotation.KeepName.
You need to ignore like you are compiling but you also need to keep the class so it can find it during runtime.
Add these two lines to your proguard configuration file:
-keep class com.google.android.gms.** { *; } -dontwarn com.google.android.gms.**
