I used 

allprojects {
repositories {
    mavenCentral()
    google()
    jcenter()

}

and

implementation 'com.facebook.android:facebook-android-sdk:[5,6)'

I have had the same problem.... as you know Android 9.0 (API level 28) there is a new version of the support library called AndroidX. You can continue to use the support library (those versioned 27 and earlier) BUT google Developer recommend using the AndroidX libraries in all new projects.

With Android Studio 3.2 and higher, you can quickly migrate an existing project to use AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.

Further reading:

https://developer.android.com/topic/libraries/support-library/ https://developer.android.com/jetpack/androidx/migrate

It worked for me. good luck

If you have use this 

 implementation 'com.android.support:appcompat-v7:28.0.2'

and also use one more dependency

 implementation 'com.android.support:support-v13:28.0.2'

this is work for me. I hope it will help you.

Try this Google Play implemented target version of API 26 so use API 27 still good

implementation 'com.android.support:appcompat-v7:27.0.1'
implementation 'com.android.support:design:27.0.1'

And also use the later version of play services

implementation 'com.google.android.gms:play-services-ads:12.0.0'
