After accepting to update the project to new version of gradle I get this error: ``` Error:Execution failed for task ':app:processDebugManifest'. Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.0-alpha1) from [com.android.support:cardview-v7:26.0.0-alpha1] AndroidManifest.xml:24:9-38 is also present at [com.android.support:design:25.3.1] AndroidManifest.xml:27:9-31 value=(25.3.1). Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:22:5-24:41 to override. ``` How can I solve this problem?

Accepted Answer

Put this at the end of your app module build.gradle:

```
configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '25.3.0'
            }
        }
    }
}
```
