Manifest Merger failed with error in Android Studio

Question

Manifest merger failed with multiple errors. See logs:

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

Answer 1

Check out for Gradle Console for Errors like

android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"

These shouldn't be declared in Manifest files of libraries that you are using..etc

You can view these errors in Gradle console which you can find under

View -> Tools Window ->  Gradle Console
