Same error with this implementation group: 'androidx.viewpager2', name:'viewpager2', version: '1.0.0-alpha01'

Then i created another empty project and implemented implementation 'androidx.viewpager2:viewpager2:1.0.0-alpha01'

and it gives me this 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-alpha04] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:5:5-19:19 to override.

Above error specific there is conflict between android.support.v4.app.CoreComponentFactory which is implementation 'com.android.support:appcompat-v7:28.0.0' and implementation 'androidx.viewpager2:viewpager2:1.0.0-alpha01'. So i removed the support:appcompat library from my project.

And it is working Now.

My question is

If i remove support:appcompat I can't use AppCompatActivity and its uses. Which is present in my existing application.

How to resolve this ?

How I can use ViewPager2 as well as support:appcompat together?

Edit

@ManoharReddy after adding tools:replace="android:appComponentFactory" inside <application> tag of manifest. It gives me this error

Its suggesting to add `tools:replace="android:appComponentFactory"` inside `` tag of manifest , just do it and check once — Manohar, Feb 18 '19 at 06:12

@ManoharReddy please check new error which is came after enabling tools:replace="android:appComponentFactory" inside tag — sushildlh, Feb 18 '19 at 06:27
Why don't you use `androidx.appcompat:appcompat:1.0.0`? and re-import `AppCompatActivity` — Kishore Jethava, Feb 18 '19 at 06:31
I did not using any `androidx.appcompat:appcompat:1.0.0` in my project. — sushildlh, Feb 18 '19 at 06:33
This version of ViewPager2 is released for Android X so if you want to use it then your project must have been migrated to Android X. — Shweta Chauhan, Feb 18 '19 at 06:39
@ShwetaChauhan but it is working in my new project if i removed in `implementation 'com.android.support:appcompat-v7:28.0.0'` — sushildlh, Feb 18 '19 at 06:54

I found the solution.

As @Kishore and @Shweta told to migrate the AndroidX in project is the solution.

Manually adding android.useAndroidX=true and android.enableJetifier=true giving me hard time. Because it's throw some error or Suggestion: add 'tools:replace="android:appComponentFactory"' to <application>

To Enable Jet-fire in project there is option in android Studio

Select Your Project ---> Right Click

app----> Refactor ----> Migrate to AndroidX

Shown in below image:-

After click on Migrate to AndroidX.

It will ask for confirmation and back up for your project.

And last step it will ask you for to do refactor.

After doing Refactor check your gradle.properties have android.useAndroidX=true and android.enableJetifier=true. If they are not then add these two lines to your gradle.properties file:

android.useAndroidX=true
android.enableJetifier=true

Thanks all the user for help.
