android manifest merger failed, gms play services / firebase

Question

I am trying to add firebase to my app using the firebaseUI. As the documentations says, I have used the corresponding gms:play-services (11.0.4) with the firebaseUI version (2.2.0) When I sync the gradle files, I receive following error:

Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.0) from [com.android.support:support-v13:26.0.0] AndroidManifest.xml:28:13-35
    is also present at [com.android.support:customtabs:25.4.0] AndroidManifest.xml:25:13-35 value=(25.4.0).
    Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:26:9-28:38 to override.

This is my gradle file:

android {
compileSdkVersion 26
buildToolsVersion "26.0.1"
defaultConfig {
    applicationId "com.test.test"
    minSdkVersion 21
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])


compile 'com.android.support:appcompat-v7:26.0.0'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:cardview-v7:26.0.0'
compile 'com.android.support:support-v13:26.0.0'
compile 'com.android.support:design:26.0.0'
compile 'com.android.support:recyclerview-v7:26.0.0'

//firebase
compile 'com.google.android.gms:play-services-auth:11.0.4'
compile 'com.google.firebase:firebase-core:11.0.4'
compile 'com.google.firebase:firebase-auth:11.0.4'
compile 'com.google.firebase:firebase-database:11.0.4'
compile 'com.google.firebase:firebase-storage:11.0.4'
compile 'com.firebaseui:firebase-ui:2.2.0'

testCompile 'junit:junit:4.12'
}

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

I've made sure that all the versions are up to date and that they are all the same. Can't figure out what the problem is?

Answer 1

I solved the problem by adding:

    configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '26.0.0'
            }
        }
    }
}

from here.

The tooltip recommended adding tools:replace="android:value"' to meta-data but this throws another error, so im going with the solution above

Answer 2

I solved it by adding this in AndroidManifest.xml within the <application> tag at the very bottom:

<meta-data 
  tools:node="replace"
  android:name="android.support.VERSION"
  android:value="26.1.0"  // <- The max version you see in the error message. For me it was 26.1.0
/>

Then add these two attributes to the <manifest ... > tag:

xmlns:tools="http://schemas.android.com/tools"
tools:node="replace"

Answer 3

It's happening because two versions of support libraries are clashing. On top, you have declared

buildToolsVersion "26.0.1"

and in dependencies, the version is 26.0.0

compile 'com.android.support:design:26.0.0'

Just change the support library version to 26.0.1 and it will work fine. I did the same, worked flawlessly in my case.

Answer 4

add this line at the end of app level gradle file

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