You should manually set the same version via DependencyResolution

Question

Error:Execution failed for task ':app:preDebugBuild'.

Android dependency 'com.google.android.gms:play-services-ads' has different version for the compile (11.8.0) and runtime (11.0.4) classpath. You should manually set the same version via DependencyResolution

My project gradle:

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.google.gms:google-services:3.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

My module gradle:

apply plugin: 'com.android.application'

apply plugin: 'com.google.gms.google-services'

How can I fix it error?

Answer 1

My error is similar with yours, solved with these way. Error is shown below :

Android dependency 'com.google.android.gms:play-services-tasks' has different version for thecompile (11.4.2) and runtime (15.0.1) classpath. You should manually set the same version via DependencyResolution

Then in file : android/build.gradle , I add this script :

    allprojects {
       ...

       configurations.all {
           resolutionStrategy.force "com.google.android.gms:play-services- 
           tasks:15.0.1"
        }

    }

Answer 2

Please see this answer You can solve it in one of two ways: Define a resolution strategy or include the offending version in your dependencies. Hope this helps!

Answer 3

Set all Google/Firebase dependency to Same version 11.8.0
