Firebase android performance NoClassDefFoundError -> FirebasePerfUrlConnection

Question

Does anyone face the same problem? After adding firebase performance to project error occurs immediately after starting the application. It is crashing only in debug build, in release build everything works as expected. Maybe someone has real answer because all I found in similar questions was juggling library versions by trial and error method. Multidex is turned ON.

Disconnection

Answer 1

Newest version of firebase works perfect. Here is sample:

Dependencies:

implementation platform('com.google.firebase:firebase-bom:28.2.1')
releaseImplementation 'com.google.firebase:firebase-analytics-ktx'
releaseImplementation 'com.google.firebase:firebase-crashlytics-ktx'
releaseImplementation 'com.google.firebase:firebase-perf-ktx'

Disconnection

Answer 2

Either include all or remove all of these

Build Gradle (AppName)

dependencies {
    classpath 'com.google.firebase:perf-plugin:1.3.4'
}

Build Gradle (:app)

At top of page

apply plugin: 'com.google.firebase.firebase-perf'

Then

dependencies {
    implementation 'com.google.firebase:firebase-perf:19.1.0'
}

Airtoair

I think "implementation 'com.google.firebase:firebase-perf:19.1.0'" is not necessary. It will autolink. – Arachnid

Answer 3

Changing

releaseImplementation 'com.google.firebase:firebase-analytics:17.4.2'
releaseImplementation 'com.google.firebase:firebase-crashlytics:17.0.0'
releaseImplementation 'com.google.firebase:firebase-perf:19.0.7'

To

implementation 'com.google.firebase:firebase-analytics:17.4.2'
implementation 'com.google.firebase:firebase-crashlytics:17.0.0'
implementation 'com.google.firebase:firebase-perf:19.0.7'

Should solve the issue as those dependencies are currently defined only for release buildType

Anemometer

This is intended, because these tools are not needed on debug. – Disconnection

I see... But this will cause ClassNotFoundException as the FirebasePerfUrlConnection in the mentioned dependencies. One way to get over this while having releaseImplementation is to: Make sure all the classes related to these dependencies are only used in release source set and no any existence in main as they won't be shipped in the debug apk – Anemometer

Answer 4

The line:

apply plugin: 'com.google.firebase.firebase-perf'

Is adding the dependencies that are causing your app to crash in debug mode. You either need to figure out a way to do that only to your release build (there are some workarounds available), or just include Firebase Performance as part of your debug build.
