Answer 1

You need to declare your dependency correctly "androidx.core:core-ktx:$core_version"

Answer 2

This is because bintray support is now no longer there. Go to your project level build.gradle and comment out the bintray dependencies in the allprojects and repositories section

Bintray Shutdown

Answer 3

As @Narendra_Nath said, it is because of the bintray dependencies and Jcenter shutting down. you can refer to this article https://blog.gradle.org/jcenter-shutdown

the solution that worked for me is changing the repositories in the (Top-level build.gradle) to

    buildscript {
      repositories {
        google()
        mavenCentral()
        maven {
        url "https://repo.spring.io/release"
        }
        maven {
        url "https://repository.jboss.org/maven2"
      } }
