Answer 1

I guess its Kotlin version related issue. First try to update your kotling version. I guess latest version is 1.2.31

The version of Kotlin to use is usually defined as the kotlin_version property:

buildscript {
    ext.kotlin_version = '1.2.31'

    repositories {
        mavenCentral()
    }

    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

I have answered a similar question here . One of the key is to update the kotlin plugin from settings in android studio.

Sorry, Silly Mistake figure out just Uncheck Offline checkbox from Gradle settings. :) Download all dependencies by build gradle online.
