Attribute application@appComponentFactory Conflict: Resolving the Issue

Error Statement:

An error occurs during the Android project build, indicating a conflict between the attribute application@appComponentFactory present in multiple libraries:

ERROR: Manifest merger failed : Attribute application@appComponentFactory value=(androidx.core.app.CoreComponentFactory) from [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 is also present at [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 value=(android.support.v4.app.CoreComponentFactory). Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:9:5-44:19 to override.

Root Cause:

This error arises when you have both Android Support Libraries and AndroidX Libraries in your project. The application@appComponentFactory attribute is present in both libraries, resulting in a conflict.

Solution:

To resolve this issue, you need to migrate your project to AndroidX or downgrade your Firebase dependencies.

Migrating to AndroidX:

1. Update your com.android.tools.build:gradle to version 3.2.1 or later.
2. Set your compileSdkVersion to 28 or higher.
3. Convert your project to use AndroidX. Refer to the official AndroidX migration guide for instructions.

Downgrading Firebase Dependencies (Not Recommended):

If you do not wish to migrate to AndroidX immediately, you can downgrade your Firebase dependencies to a version that supports Android Support Libraries. However, this is not a long-term solution as Firebase will eventually require AndroidX.
