Android Studio 3.3.2 kotlin Compiler Warning

Question

I am using,

 Android Studio Version - 3.3.2
 minSdkVersion 19
 targetSdkVersion 27

Kotling plugin :

 apply plugin: 'kotlin-android'
 apply plugin: 'kotlin-android-extensions'
 apply plugin: 'kotlin-kapt'

kotlin build file :

implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"

In top level build-gradle

ext.kotlin_version = '1.3.21'

classpath 'com.android.tools.build:gradle:3.3.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.2.0'
classpath 'io.fabric.tools:gradle:1.27.1'

My Issue is Its giving me Lots of Kotlin Compiler Warning.

I have not issue with this warning but I want to add,

shrinkResources true
minifyEnabled true 

in my application, but due to warning this giving me an error to solve warning first.

Please see my number of warning in screen shot, and if any have having solutions of it then please give ans here.

Edit
