Android Manifest merger failed || Manifest merger failed with multiple errors, see logs

Question

I am working on a App using Firebase. I got a issue which needs to get solved. When i go to run the app it shows in build.

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:10:5-31:19 to override.

I searched the whole internet to solve the issue failed. I also added

tools:replace="android:appComponentFactory"

in the AndroidManifest.xml file. I also followed the answer of This Question. but it didn't work for me saying

Manifest merger failed with multiple errors, see logs

when question is related to manifest file, why have you posted gradle file instead of manifest ? — Vivek Mishra

Just a tip, in the bottom of the manifest you can access the "Merged Manifest" to check the errors.

If you can't figure out the erros, post your manifest so we can help.
