Conflict with Android dependency 'com.google.android.gms:play-services-measurement-base'

[Purus]

Using this plugin along with the latest version of Firebase, gives the below issue while building. I guess this is due to the version conflicts of the dependency.

Launching lib\main.dart on MotoG3 in debug mode...
Initializing gradle...
Resolving dependencies...
Gradle task 'assembleDebug'...
registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)

* What went wrong:
Execution failed for task ':app:preDebugBuild'.
> Android dependency 'com.google.android.gms:play-services-measurement-base' has different version for the compile (16.0.3) and runtime (16.0.4) classpath. You should manually set the same version via DependencyResolution

Please note, I am not using firebase_admob, but the other firebase plugins..

Hi @Purus! I think this is a know issue and Google has some words about it here in their release notes: https://developers.google.com/android/guides/releases#november_13_2018

I know only a little about Gradle and Android dependency management. Can you try forcing version for that dependency to 16.0.4 or 16.0.5 and see if it solves your issue?

@Purus — I'm using this plugin as well and ran into similar problems. What worked for me was updating all the firebase dependencies in my app level build.gradle to their latest and then adding all the Kotlin dependencies that were not in my project for BOTH the build.gradle and app level build.gradle

Add lines 2 and 10 from: https://github.com/YoussefKababe/admob_flutter/blob/master/example/android/build.gradle#L2
Add lines 25 and 63 from: https://github.com/YoussefKababe/admob_flutter/blob/master/example/android/app/build.gradle#L25

Also using gradle 4.6 for the distributionUrl in gradle-wrapper.properties (not sure if this one matters)

@gctommy Can you share me how you updated all firebase dependencies in the app level build.gradle file? I am new to Android..
@YoussefKababe Thanks. I am trying to find out how to update such dependencies.

Try
Add lines 2 and 10 from: https://github.com/YoussefKababe/admob_flutter/blob/master/example/android/build.gradle#L2
and
Add lines 25 and 63 from: https://github.com/YoussefKababe/admob_flutter/blob/master/example/android/app/build.gradle#L25

but still error

then i add this on android/build.grade, its working
subprojects {
configurations.all() {
resolutionStrategy.force "com.google.firebase:firebase-core:16.0.5"
}
}

I reverted back all the changes mentioned by @gctommy and added the code mentioned by @apitutinteractive .

And voila.. it's now working. Thanks all for the work solution. Great guys..
