Trying to create a simple app with FireStore and Google Authentication. Having problem with the gradle:
In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[15.0. 1]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.
Dependency failing: com.google.android.gms:play-services-flags:15.0.1 -> com.google.android.gms:play-services-basement@[ 15.0.1], but play-services-basement version was 16.0.1.
The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art ifact with the issue. -- Project 'app' depends onto com.google.firebase:[email protected] -- Project 'app' depends onto com.firebaseui:[email protected]
For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https:// github.com/google/play-services-plugins and disable by adding "googleServices { disableVersionCheck = false }" to your b uild.gradle file.

Project gradle:
buildscript { repositories { google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.2.1' classpath 'com.google.gms:google-services:4.2.0' } }
Can somebody help me?
There are many answers here for individual solutions that do not really get down to the problem. Here is how to solve this in general:
As the original log output suggests, it is useful to run the build in the terminal with the following command:
./gradlew --info assembleDebug
This will give you a list of all dependencies that are involved in the conflict. It looks similar to this (I removed the package name stuff to make it a bit more readable):
Dependency Resolution Help: Displaying all currently known paths to any version of the dependency: Artifact(groupId=com.google.firebase, artifactId=firebase-iid) -- task/module dep -> [email protected] ---- firebase-analytics:17.2.0 library depends -> [email protected] ------ play-services-measurement-api:17.2.0 library depends -> [email protected] -- task/module dep -> [email protected] ---- firebase-core:17.2.0 library depends -> [email protected] ------ firebase-analytics:17.2.0 library depends -> [email protected] -------- play-services-measurement-api:17.2.0 library depends -> [email protected] -- task/module dep -> [email protected] ---- play-services-measurement-api:17.2.0 library depends -> [email protected] -- task/module dep -> [email protected] -- task/module dep -> [email protected] ---- firebase-messaging:17.1.0 library depends -> firebase-iid@[16.2.0] -- task/module dep -> com.pressenger:[email protected] ---- com.pressenger:sdk:4.8.0 library depends -> [email protected] ------ firebase-messaging:17.1.0 library depends -> firebase-iid@[16.2.0]
From this list you get to know 2 things:
In my case the conflicting dependency is firebase-iid
: It's either @19.0.0
or @16.2.0
To fix this you must define the top-level dependency of the wrong firebase-iid
explicitly in your build.gralde
.
So in the upper log you can see that there are 2 examples of an out-dated version of [email protected]. One comes from -- task/module dep -> [email protected]
the other one from a third-party library (pressenger). We don't have influence on the third-party library, so nothing to do here. But for the other dependency, we have to declare it explicitly with the correct version:
implementation 'com.google.firebase:firebase-messaging:20.0.0'
Now the build works again. Happy ending :)
There's a known bug with Google Services 4.2.0 that may cause this. Downgrading your google-services version to 4.1.0 in your project's build.gradle may resolve the issue
buildscript { dependencies { classpath 'com.google.gms:google-services:4.1.0' //decreased from 4.2.0 } }
