***********************************************************************

package www.abhishek.com.kotlin
import android.content.Intent
import android.os.Bundle
import android.support.v7.app.AppCompatActivity


/**
 * Created by abhishek
 * https://abhiandroidknowledge.blogspot.com/2018/03/splashscreen.html
 * */

class SplashScreen : AppCompatActivity() {

    private val SPLASH_TIME:Long = 5000 // 5 second
    // inner class intialise
    private var intentLaucher: IntentLaucher? = null 

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.splash_screen)

        intentLaucher = IntentLaucher() // create inner class object
        intentLaucher!!.start() // call thread

    }

    /**
     * IntentLuncher to extends Thread and implement run method
     */
    inner class IntentLaucher : Thread() {

        override fun run() {
            try {
                Thread.sleep(SPLASH_TIME)
            } catch (e: InterruptedException) {
                e.printStackTrace()
            }

            startActivity(Intent(this@SplashScreen,MainActivity::class.java))
            finish()

        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>
***********************************************************************
5: Create activity_main.xml

***********************************************************************
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="www.paymonk.com.kridhankotlin.MainActivity">

    <TextView
        android:id="@+id/tv_splashScreen"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Main Page"
        android:textAppearance="@style/Base.TextAppearance.AppCompat.Large"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>
***********************************************************************
6: Create MainActivity.kt

***********************************************************************
package www.abhishek.com.kotlin

import android.os.Bundle
import android.support.v7.app.AppCompatActivity
import kotlinx.android.synthetic.main.activity_main.*

/**
 * Created by abhishek
 * https://abhiandroidknowledge.blogspot.com/2018/03/splashscreen.html
 * */

class MainActivity : AppCompatActivity() {


    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        //call textview to id 
        tv_splashScreen.setText("Replace own code")
