Kotlin, a statically typed programming language, is widely used for Android development and other JVM-based applications. It provides robust support for mathematical operations, leveraging both standard library functions and Java's mathematical capabilities. Here's an overview of how to perform common mathematical operations in Kotlin: 1.  Basic Arithmetic Operations Kotlin supports standard arithmetic operations like addition, subtraction, multiplication, division, and modulus.

 Kotlin package com.example.googlesignin import android.app.Activity import android.content.Intent import android.os.Bundle import android.util.Log import android.widget.Toast import androidx.activity. result.ActivityResultLauncher import androidx.activity.result.contract.ActivityResultContracts import androidx.appcompat.app.AppCompatActivity import com.google.android.gms.auth.api.signin.GoogleSignIn import com.google.android.gms.auth.api.signin.GoogleSignInAccount import com.google.android.gms.auth.api.signin.GoogleSignInClient import com.google.android.gms.auth.api.signin.GoogleSignInOptions import com.google.android.gms.common.api.ApiException import com.google.android.gms.tasks.Task import com.example.googlesignin. databinding.ActivityMainBinding

In Kotlin, **nested try blocks** allow you to handle exceptions at different levels of code execution. They are useful when specific parts of your code might throw distinct exceptions that require localized handling, while other exceptions are managed at a broader level. Here's a breakdown of how they work: --- **Structure of Nested Try Blocks** A nested `try` block is a `try`-`catch`-`finally` construct placed inside another `try` block: ```kotlin try {     // Outer try block     try {         // Inner try block     } catch (e: SpecificException) {         // Inner catch block     } finally {         // Inner finally (optional)     } } catch (e: Exception) {     // Outer catch block } finally {     // Outer finally block (optional) } ``` --- **Key Concepts** 1. **Exception Propagation**:    - If an exception occurs in the **inner `try` block**, the...

  First    we add the following permission to the Manifest file <uses-permission android:name = "android.permission.FOREGROUND_SERVICE" /> Then we add the following libraries to Gradle Dependencies implementation ("androidx.media3:media3-exoplayer:1.2.1") implementation ("androidx.media3:media3-ui:1.2.1") implementation ("androidx.media3:media3-common:1.2.1") implementation( "androidx.media3:media3-session:1.2.1") We synchronize them (we SYNC).  We add the following "val" into the Main Activity. val player = ExoPlayer . Builder ( context ). build () val mediaSession = MediaSession . Builder ( context , player ). build () To take this player to a more advanced level We add the following code into the main activity. class PlaybackService : MediaSessionService () {     private var mediaSession : MediaSession ? = null     // Create your Player and MediaSession in the onCreate lifecycle event     override fun...
