Firebase Performance Monitor is a useful tool to make the Android application better. But when it is connected, the assembly time of our project immediately increased by 20-30 seconds, which, you see, is not short.
We are not alone, and I decided to publish the solution found on the Medium. I hope it will help and save you precious time building the project.
How to reduce the build time of a project using the Firebase Performance Plugin
Recently I added the Firebase Performance Plugin to one of my projects and faced a radical increase in the build time of the application. Initially, the assembly took place in less than 20 seconds, after adding a plug-in - 5-6 minutes. The behavior is annoying, so I looked at what increases the assembly time.
If you look closely, you can see that the next Gradle task takes a very long time:
app:transformClassesWithFirebasePerformancePluginForDebug
There is a post-compilation phase that uses Firebase Performance on Android and leads to an increase in build time.
How to smooth the problem
The fix I applied smoothes the problem by adding a parameter to the build command so that the plugin can be disabled during development.
In the
root/buildscript/dependencies block, wrap the
classpath plugin in the following condition:
if (!project.hasProperty("disable-performance-plugin")) { classpath('com.google.firebase:firebase-plugins:1.1.5') { exclude group: 'com.google.guava', module: 'guava-jdk5' } }
The need to exclude
com.google.guava depends on whether the library leads to conflicts with your dependencies on Guava, as described in
the documentation .
Then, in
app/build.gradle add the following condition:
if (!project.hasProperty("disable-performance-plugin")) { apply plugin: 'com.google.firebase.firebase-perf' }
Now you can simply build the project via the command line, using the parameter to disable the plugin:
./gradlew your-task -Pdisable-performance-plugin
If you are using Android Studio to build a project, you can add the same setting in the “Compiler Setup” section. You need to set command line options,
-Pdisable-performance-plugin
That's all. Adding this option will make your life easier!
