androidx and support dependency causing multidex error

I have a library project which is using androidx dependency in it.

implementation 'androidx.appcompat:appcompat:1.0.0-rc01'

After adding library project in my app, i am getting multiple errors related to dexMerger , MultiDex , Multiple dex files define Landroid/support/v4/... .

So i searched for that file by using window+O (Navigate --> Class). Then i found that same class is used in 'androidx.appcompat:appcompat:1.0.0-rc01' and android.support.v4.. libraries . So I tried to exclude like below -

    implementation('androidx.appcompat:appcompat:1.0.0-rc01') {
         exclude module: 'support-v4'
    }

Also i have added multidex true but nothing helped. I read about AndroidX looks like it contains many classes that are similar to support libraries. What should be done in this case ? I have latest version of Android Studio and my compileSdkVersion is 28. My all dependencies are up to date. I have already added multidex dependency and my application class is also extending MultiDexApplication.

Use the Following Command to check which dependency has duplicate class

./gradlew app:dependencies

Then Exclude the module like this

{
  exclude group: 'com.android.support'
}

Hope this will solve your problem! Let me know if you have any issues!

Just setting the multidex true is not enough.

You need to include this dependency first

implementation 'com.android.support:multidex:1.0.3'

then 

defaultConfig {
        ...
        multiDexEnabled true
    }

then in ur manifest

<application
        android:name="android.support.multidex.MultiDexApplication" >
        ...
</application>
