Splash screen Android Kotlin

 Creat a Activity name  "SplashActivity"

Write code in kotlin file

// Delay for 3 seconds and then launch MainActivity
Handler(Looper.getMainLooper()).postDelayed({
    val mainIntent = Intent(this, MainActivity::class.java)
    startActivity(mainIntent)
    finish()
}, 3000) 

Here -  3000 milliseconds = 3 seconds

Got to Manifest file

Add this code for Splash as launcher activity. And remove this code from MainActivity.

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>


Full Code:
<activity
    android:name=".SplashActivity"
    android:exported="true"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
