i am getting an ERROR message while working on android project based on voice assistant

Error : Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory). Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:8:5-31:19 to override.

  • If you are in Android Studio, go to your manifest.xml file and change the view from "Text" to "Merged" (below the code white page); there you can find more details and shortcuts – Luca Murra Oct 26 '19 at 14:45

You are using com.google.android.gms:play-services-vision:19.0.0 which depends on the AndroidX version. Play Services Change Log. Try using version 17.0.0, it will solve the issue hopefully. Play Services Change Log
