I can not upload my app to the playstore console

I tried to upload my latest version of my app, but I get an error in the playstore

This is after updating compileSdkVersion to Android-P and bringing Android support dependencies 28.0.0-alpha1

I get this exactly in the playstore

The oradle of the project is as follows

buildscript {
    ext.kotlin_version = '1.2.30'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:3.2.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url "https://jitpack.io"                
        }
    }
}

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

Maybe it's due to the dependencies that are in alpha? There is some way I can upload it with that oradle or similar, but that does not affect so much since I'm using the design that comes with version 28.
