Manifest merger Failed after adding Google Firebase Authentication

After adding Firebase Authentication to app implementation I got a Manifest Merger failed error.

"Manifest merger failed with multiple errors, see logs"

I tried using different versions of the authentication but didn't work. The solutions for the same type of problems in StackOverflow didn't work for me.

I tried the suggested changes in Merged manifest but this error came up again

Merging Errors: Error: tools:replace specified at line:6 for attribute android:appComponentFactory, but no new value specified app main manifest (this file), line 5 Error: Validation failed, exiting app main manifest (this file)

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        tools:replace="android:appComponentFactory">
        <activity android:name=".VerifyEmployeeID"></activity>
        <activity android:name=".SignUp" />
        <activity android:name=".login" />
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'


    implementation 'com.google.firebase:firebase-core:16.0.5'
    implementation 'com.google.firebase:firebase-auth:16.0.5'

    //firebase database
    implementation 'com.google.firebase:firebase-database:16.0.4'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

I need to get rid of this error.

This happens because you are using simple dependency or androidx support dependency. That's why this error occurs.

Remove below the line in Manifest.xml

tools:replace="android:appComponentFactory"

Use this dependency in build.gradle

implementation 'com.google.firebase:firebase-core:16.0.9'

implementation 'com.google.firebase:firebase-auth:17.0.0'

Remove all androidx dependency in your build.gradle file and sync project.
