Android manifest merge error

Question

I am using Unity3D for my project, but am having issues building to Android.

The error I get is this:

/Volumes/MacBackup/AppsProduction/MyApp/Temp/StagingArea/AndroidManifest-main.xml:24:9-31 Error: Attribute meta-data#android.support.VERSION@value value=(25.3.1) from AndroidManifest.xml:24:9-31 is also present at AndroidManifest.xml:27:9-38 value=(26.0.0-alpha1). Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest-main.xml:22:5-24:34 to override.

UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()

My manifest looks like this:

Unity gives me this solution to try, but do not know where to put it:

tools:replace="android:value

I have searched the internet for a solution on this and a lot comes up with changing something in the build.gradle but do not know where that is in Unity.

Hoping for help in this matter and thanks in advance :-)
