// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        classpath 'com.google.gms:google-services:4.2.0'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir

        </android.support.design.widget.BottomNavigationView>

    </android.support.design.widget.AppBarLayout>


</RelativeLayout>

my Activity_home.xml

my 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:1.1.0-alpha03] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:7:5-25:19 to override.

I can't solve even though i already try all things. Even though I add these two lines of code in application tag in manifest.xml.

tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"

but it didn't work, after that show error more.

How can I solve this?

Since you are not using androidx you don't need

   implementation com.google.android.material:material

remove this line from gradle.

For androidx

 com.google.android.material:material

should be used, and if you are using support library

  com.android.support:design

is enough.

Adding the below properties in your gradle.properties file can resolve your problem.

android.useAndroidX=true android.enableJetifier=true
