Android build issue: "Execution failed for task ':app:checkDebugDuplicateClasses'."

[sethcwhiting]

I'm a JS/React/React Native dev who rarely needs to deal with native code and I'm struggling a bit to get my app running with this package installed. I followed each step of the installation instructions, and I was able to eventually get the project to build on iOS with a lot of help from a friend who's an iOS expert. I'm still struggling with the Android build, though. I'm getting this error:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:checkDebugDuplicateClasses'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable
   > Duplicate class com.google.android.gms.internal.measurement.zzbm found in modules jetified-play-services-measurement-17.2.1-runtime (com.google.android.gms:play-services-measurement:17.2.1) and jetified-play-services-measurement-base-20.1.2-runtime (com.google.android.gms:play-services-measurement-base:20.1.2)

It seems like there's probably a conflict with another package I'm using on the project, but I'm at a bit of a loss as to which one. Then once I find the conflicting package, I'm not really sure how to go about resolving the conflict. Any help/insight I could get on this would be greatly appreciated. For context, here's my android/app/build.gradle file:

I tried most of the solutions in this thread, and I was able to get it to the point where it built successfully, but then immediately crashed every time I opened the app. Also, in order to do that, I had to downgrade a few things. I was hoping to not have to do that, but if I need to in order for it to work, that's fine.

[aziradevs]

i have solved this issue by removing the all firebase dependencies and added only the dependency what the code needed.
i use Android Studio and it seems u use React Native so i hope logic are same for both

[jorgegvallejo]

Hey @sethcwhiting did you solve the crash on launch?

[sethcwhiting]

Hey guys I’m reopening this now.
I ran ./gradlew app::dependencies in my android/ folder and found that expo-firebase-analytics was the culprit. I removed that package so that I could just work on AdMob stuff for a while, but now I’m at the point where I really need analytics back.

@ammarahm-ed do you or anyone else know of any way to reconcile the 2 packages? Maybe force react-native-admob-native-ads to use com.google.android.gms:play-services-measurement-sdk-api:17.2.1 or something?

[aziradevs]

Try Latest Firebase analytics dependency.

[sethcwhiting]

thanks, @emdotysru21, When I do that, I get a bunch of other errors on Android and my iOS build breaks.
It seems to me like the best way to go about this would be to reference com.google.android.gms:play-services-measurement:17.2.1 in react-native-admob-native-ads, but I'm not sure how to do that

Facing this same issue. I'm unable to use this library alongside react-native-notifications's default firebase version: implementation 'com.google.firebase:firebase-core:16.0.0'.

I was able to get it working but I had to upgrade to implementation 'com.google.firebase:firebase-core:20.1.2' to match this library's but not sure if that'll introduce issues/regressions for notifications. Will update here if so.
