Resolve the "Program type already present" conflict by running the ./gradlew app:dependencies command to identify and remove duplicate com.google.android.gms entries. Utilize resolutionStrategy in your build.gradle file to enforce a unified version:

configurations.all {
    // pragma ("One ring to rule them all!") 
    resolutionStrategy.force 'com.google.android.gms:play-services-measurement-base:x.y.z'
}

Swap x.y.z with the current version number required to align your Google Play services dependencies.

Refrain from using outdated Firebase SDK. Update all Firebase dependencies and check the release notes for any helpful conflict resolution.

Also, confirm the classpath for the google-services plugin in your build.gradle file is current:

buildscript {
    ...
    dependencies {
       // who's the latest? I'm the latest!
       classpath 'com.google.gms:google-services:4.3.3'
    }
}

The Demystification of Class Conflicts

Redundant Library Check-up

Excess baggage of redundant libraries might gravitate your app.

Examine your project's dependency tree - ./gradlew app:dependencies will leave no stone unturned.
Excise any explicit dependencies that are already included transitively through others.

Google Play Services Alignment

Give your Google Play Services dependencies the same version number. Your app will thank you for it.

Don't have conflicting versions of Google Play services or Firebase libraries. They don't play well together.
Make sure to use the same version number for peace, harmony, and compatibility.

Follow the official scroll

Stay abreast of current best practices to avoid common missteps:

Scout the Firebase Android SDK release notes for conflict hints.
Follow the steps shared in the official Firebase SDK versioning article.

Keep your dependencies prim and proper

Embrace the latest Kid on the Block

Embrace the latest versions for better stability and fixes:

Keep your Firebase SDKs updated.
Update libraries like grpc - "the more, the merrier."

Eyes on Compatibility Notes

Watch out for compatibility hiccups while updating:

Eyes on the up-to-date release notes – no surprises here.
Stay vigilant about runtime crashes post module exclusion.

Update for an Optimized Performance

Updating individual libraries ensures tip-top performance:

Using the latest versions makes your app feel like it’s on steroids.
High time, adopt the most recent version of a conflicting library.

Migrate to better tooling

Equip Top-tier tools

Equip your project with the latest tools:

The latest version of com.android.tools.build:gradle should be on your speed-dial.
Keep your google-services classpath updated in your build.gradle file.

Efficient Troubleshooting

Who wouldn’t love to resolve conflicts swiftly?

Dive into the Gradle log for the stack trace relating to dexing and merging issues.
Leverage ProGuard rules and multiDex configuration to tackle Too many cooks (methods) problem!
