Mobile build (Android/iOS) in Unity - Mini Project: Build & Apply

Mobile Build Setup for Android and iOS in Unity

📖 Scenario: You are creating a simple Unity project that you want to build for both Android and iOS devices. This project will help you understand how to set up the build settings and configure platform-specific options.

🎯 Goal: Learn how to prepare a Unity project for mobile builds by setting up the initial scene, configuring build settings for Android and iOS, and finally building the project.

📋 What You'll Learn

Create a simple Unity scene with a cube

Set up build settings for Android

Set up build settings for iOS

Build the project and display the build path

💡 Why This Matters

🌍 Real World

Mobile game and app developers use Unity to create games and apps that run on Android and iOS devices. Knowing how to set up builds for these platforms is essential to publish your app.

💼 Career

Many game development and mobile app development jobs require knowledge of Unity build processes for Android and iOS platforms to deliver apps to users.

1

Create a simple Unity scene with a cube

In Unity, create a new scene and add a GameObject cube named MyCube at position (0, 0, 0). Write the C# code to create this cube in the Start() method of a script called SetupScene.

Unity

using UnityEngine;

public class SetupScene : MonoBehaviour
{
    void Start()
    {
        // Your code here
    }
}

Use GameObject.CreatePrimitive(PrimitiveType.Cube) to create a cube and set its name and position.

2

Configure build settings for Android

Add code to set the build target to BuildTarget.Android and set the Android bundle identifier to com.example.myapp using PlayerSettings.applicationIdentifier. Write this code in a new method called ConfigureAndroidBuild().

Unity

using UnityEngine;
using UnityEditor;

public class SetupScene : MonoBehaviour
{
    void Start()
    {
        GameObject MyCube = GameObject.CreatePrimitive(PrimitiveType.Cube);
        MyCube.name = "MyCube";
        MyCube.transform.position = new Vector3(0, 0, 0);
    }

    void ConfigureAndroidBuild()
    {
        // Your code here
    }
}

Need a hint?

Use EditorUserBuildSettings.SwitchActiveBuildTarget to switch to Android and set PlayerSettings.applicationIdentifier for the bundle ID.

3

Configure build settings for iOS

Add a method called ConfigureiOSBuild() that switches the build target to BuildTarget.iOS and sets the iOS bundle identifier to com.example.myapp.ios using PlayerSettings.applicationIdentifier.

Unity

using UnityEngine;
using UnityEditor;

public class SetupScene : MonoBehaviour
{
    void Start()
    {
        GameObject MyCube = GameObject.CreatePrimitive(PrimitiveType.Cube);
        MyCube.name = "MyCube";
        MyCube.transform.position = new Vector3(0, 0, 0);
    }

    void ConfigureAndroidBuild()
    {
        EditorUserBuildSettings.SwitchActiveBuildTarget(BuildTargetGroup.Android, BuildTarget.Android);
        PlayerSettings.applicationIdentifier = "com.example.myapp";
    }

    void ConfigureiOSBuild()
    {
        // Your code here
    }
}

Need a hint?

Use EditorUserBuildSettings.SwitchActiveBuildTarget to switch to iOS and set PlayerSettings.applicationIdentifier for the iOS bundle ID.

4

Build the project and display the build path

Write a method called BuildProject() that builds the current scene to a folder called Builds/MobileBuild and prints the build path using Debug.Log. Call this method from Start() after creating the cube.

Unity

using UnityEngine;
using UnityEditor;

public class SetupScene : MonoBehaviour
{
    void Start()
    {
        GameObject MyCube = GameObject.CreatePrimitive(PrimitiveType.Cube);
        MyCube.name = "MyCube";
        MyCube.transform.position = new Vector3(0, 0, 0);

        // Your code here
    }

    void ConfigureAndroidBuild()
    {
        EditorUserBuildSettings.SwitchActiveBuildTarget(BuildTargetGroup.Android, BuildTarget.Android);
        PlayerSettings.applicationIdentifier = "com.example.myapp";
    }

    void ConfigureiOSBuild()
    {
        EditorUserBuildSettings.SwitchActiveBuildTarget(BuildTargetGroup.iOS, BuildTarget.iOS);
        PlayerSettings.applicationIdentifier = "com.example.myapp.ios";
    }

    void BuildProject()
    {
        // Your code here
    }
}

Need a hint?

Use BuildPipeline.BuildPlayer with the current scene path and print the build path with Debug.Log.
