How to fix. Error:Execution failed for task ':app:processDebugManifest'. VERSION@value value=(26.1.0)

Question

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

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.1.0) from [com.android.support:design:26.1.0] AndroidManifest.xml:28:13-35 is also present at [com.android.support:support-v13:26.0.1] AndroidManifest.xml:28:13-35 value=(26.0.1). Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest.xml:26:9-28:38 to override.

Answer 1

Library com.android.support:support-v13:26.0.1 has a meta tag inside its manifest

 <meta-data
        android:name="android.support.VERSION"
        android:value="26.0.1" />

Your another library com.android.support:design:26.1.0 has this meta tag

 <meta-data
        android:name="android.support.VERSION"
        android:value="26.1.0" />

When we build the app library manifests will merge so multiple libraries have the same meta tag with the different value. it will cause conflict.

If you want to get rid of this add this meta tag in your app manifest

<meta-data
        tools:replace="android:value"
        android:name="android.support.VERSION"
        android:value="26.1.0" />

**

<**application
....
..... <meta-data
            tools:replace="android:value"
            android:name="android.support.VERSION"
            android:value="26.1.0" />
</application**

** just add this to get rid of the conflict
