Firebase Performance Plugin Causes Slow Build Time

Question

When using Firebase Performance in Android Studio, the app:transformClassesWithFirebasePerformancePluginForDebugGradle Task app:transformClassesWithFirebasePerformancePluginForDebugtakes significantly longer than any other task, and therefore significantly slows down the Gradle build time.

Slow assembly is displayed in the profiler

Answer 1

Firebase in our project led to an increase in build time by 40%. To speed up debugging builds, we added the ability to enable / disable it using the build options in the app / build.gradle and root build.gradle files:

Application:

if (!project.hasProperty("disable-performance-plugin"))  {
    apply plugin: 'com.google.firebase.firebase-perf' 
}

root / buildscript / dependencies:

if (!project.hasProperty("disable-performance-plugin")) {
    classpath('com.google.firebase:firebase-plugins:1.1.5') {
        exclude group: 'com.google.guava', module: 'guava-jdk5'
    }
}

when starting from the command line use

./gradlew your-task  -Pdisable-performance-plugin

Firebase Performance perf-plugin (v1.3.0). Firebase Performance Monitoring Gradle ( buildTypes productFlavors).

:

 android {
      // ...

      debug {
        FirebasePerformance {
          // Set this flag to 'false' to disable @AddTrace annotation processing and
          // automatic HTTP/S network request monitoring
          // for a specific build variant at compile time.
          instrumentationEnabled false
        }
      }
    }

For newer versions of the Firebase Perf plugin ( 1.3.0and higher) with Kotlin DSL, you need to add the following:

android {
  ...
  buildTypes {
    ...
    all {   
      with((this as ExtensionAware).extensions["FirebasePerformance"] as FirebasePerfExtension) {
        setInstrumentationEnabled(!isDebuggable)
      }     
    }
    ...
  }

}

For the Groovy version, you can read the Firebase documentation .
