Hello, I'm trying to disable firebase performance monitoring instrumentation for debug builds of an Android application. Sadly the examples are only in Groovy and I'm having issues understanding how should I get access to the FirebasePerformance object in order to configure it.

Documentation
https://firebase.google.com/docs/perf-mon/disable-sdk?platform=android

Groovy example from the documentation

groovy
android {
  // ...
  buildTypes {
    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
      }
    }
  }
}

My build.gradle.kts has something like

kotlin
  buildTypes {
    getByName("debug") {
        // should disable it here but don't know how to get the reference
    }

Any idea how can I get access to the FirebasePerformance object from inside getByName("debug") ?

"FirebasePerformance" is an extension on the project, you should be able to get it with something like: configure<FirebasePerfExtension> {}

[mbonnin]

I don't think it needs to be in the android closure.

[mbonnin]

Or something like

extensions.getByName("FirebasePerformance") {
    this as FirebasePerfExtension
}

Hi Martin. I tried

val firebase = extensions.getByName("FirebasePerformance") as FirebasePerfExtension
firebase.setInstrumentationEnabled(true)

But is doesn't exist inside android{} or outside

Extension with name 'FirebasePerformance' does not exist.

[mbonnin]

damn, right, it's not applied on the project...

[mbonnin]

private static void registerExtension(AppExtension androidExt) {
        androidExt.getBuildTypes().all((buildType) -> {
            ((ExtensionAware)buildType).getExtensions().add("FirebasePerformance", FirebasePerfExtension.class);
        });
        androidExt.getProductFlavors().all((productFlavor) -> {
            ((ExtensionAware)productFlavor).getExtensions().add("FirebasePerformance", FirebasePerfExtension.class);
        });
    }

[mbonnin]

so something like:
(buildType as ExtensionAware).extensions.getByName("FirebasePerformance")

[mbonnin]

(I just edited to add extensions, I think you'll need that)

[mbonnin]

That should also work on a productFlavor, not only buildType

[robertoestivill]

buildTypes {
    getByName("debug") {
      val firebasePerf = (this as ExtensionAware).extensions.getByName("FirebasePerformance")
      (firebasePerf as FirebasePerfExtension).setInstrumentationEnabled(true)

...

Nope. Still not found. I was walking this way this morning but could nailed the details...

[robertoestivill]

Extension with name 'FirebasePerformance' does not exist. Currently registered extension names: [ext]

[robertoestivill]

Where would you call that function that you sent me? registerExtension ? maybe that's what's missing 🤔

[mbonnin]

I got it from the plugin jar, it's the code that registers the extension

[mbonnin]

If you search FirebasePerfPlugin in IntelliJ, you should have it

[mbonnin]

Or maybe the extensions are not registered yet ?

[mbonnin]

You can also try to hook a debugger with -Dorg.gradle.debug=true from the command line and a remote config in idea to see what's going on

[robertoestivill]

Ahhh you pointed me to the right place. The plugin was applied in the parent build file but not in the android app module. I added it and the following worked as we expected:

buildTypes {
    getByName("debug") {

      val firebasePerf = (this as ExtensionAware).extensions.getByName("FirebasePerformance")
      (firebasePerf as FirebasePerfExtension).setInstrumentationEnabled(true)
...

[robertoestivill]

Thanks for the help man!

[mbonnin]

No pb. I hope plugins will do less of this extension magic now that kotlin dsl is a thing. That'll make them more discoverable

[robertoestivill]

I would love to see that too!

We just avoid application of plugin. Apply when special Gradle property is passed
