Update Kotlin to version 1.3.31

Resolved error:
The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.0 and higher.
The following dependencies do not satisfy the required version:
root project 'android-media-controller' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.30

Resolved warning:
WARNING: The specified Android SDK Build Tools version (27.0.3) is ignored, as
it is below the minimum supported version (28.0.3) for Android Gradle Plugin
3.3.2.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '27.0.3'" from your
build.gradle file, as each version of the Android Gradle Plugin now has a
default version of the build tools.
