  • UI and game logic tested in editor

✅ Enable Developer Mode on Android Device (For Testing)

If you’re planning to install the APK on a real device:

  4. Allow authorization when prompted.

Unity 6 Build APK Android: Full Setup

Let’s walk through the steps to Unity 6 build APK Android using the new Build Settings interface and configuration tools.

Step 1: Open Build Settings

  1. In Unity, go to File > Build Settings.

  2. Choose Android from the platform list.

  3. Click Switch Platform (if not already selected).

Note: This may take a minute as Unity reconfigures your assets for Android.

Step 2: Add Your Scene

Make sure your main scene is in the build list:

  • Click Add Open Scenes if it isn’t listed.

  • Arrange the scenes in the desired load order.

Step 3: Set Player Settings

Click the Player Settings button at the bottom of the Build Settings window.

Under Other Settings:

  • Scripting Backend: IL2CPP (recommended)

  • API Level: Match the minimum Android API level required for your target devices

  • Target Architectures: ARMv7 and ARM64 (enable both for best compatibility)

  • Internet Access: Auto or Require (depending on your app)

Under Identification:

  • Package Name: Use reverse domain format like com.yourcompany.yourapp

  • Version: Set your app version (e.g., 1.0.0)

  • Bundle Version Code: Integer value (increment with each update)

Under Publishing Settings:

  • If you’re planning to publish your APK, configure Keystore, Key Alias, and Passwords.

Unity 6 Build APK File: Step-by-Step

Now let’s generate the actual APK file.

Step 1: Choose Build Type

You have two main options:

  • Build: Generates an APK you can install manually.

  • Build and Run: Builds the APK and installs it on your connected Android device immediately — a convenient option if you’re following a guide on how to build apk in Unity 6 and want to test changes quickly.

Step 2: Build Process

  1. In the Build Settings window, click Build.

  2. Choose a destination folder (e.g., Builds/Android).

  3. Name your file, e.g., MyGame.apk.

  4. Unity will compile your project and generate the APK.

Note: First-time builds may take several minutes. Unity uses Gradle under the hood, so let it complete without interruption.

Step 3: Test the APK

After the build completes:

  • Transfer the APK to your Android device manually or via USB.

  • Tap the file to install (you might need to enable Install from Unknown Sources).

  • Run your game and test performance, UI, and device compatibility.

Build APK Unity 6 Tutorial: Advanced Tips

This build apk Unity 6 tutorial wouldn’t be complete without pro tips for optimizing and automating your workflow.

✅ Tip 1: Use Custom Keystore for Google Play Publishing

To upload your APK to Google Play, you must sign it with a secure keystore.

How to create and use a keystore in Unity 6:

  1. Go to Player Settings > Publishing Settings.

  2. Click Keystore Manager.

  3. Create a new keystore file.

  4. Fill in alias, passwords, and validity years.

  5. Unity will use this to sign your APK.

Note: Save your keystore securely, losing it means you can’t update your app later.

✅ Tip 2: Automate Builds with Build Scripts

Unity supports scripting the build process using C#. Here’s a simple example:

using UnityEditor;
using UnityEngine;

public class BuildAPK {
    [MenuItem("Build/Build Android APK")]
    public static void BuildGame() {
        string[] scenes = { "Assets/Scenes/Main.unity" };
        BuildPipeline.BuildPlayer(scenes, "Builds/MyGame.apk", BuildTarget.Android, BuildOptions.None);
    }
}

Place this in an Editor folder, and you’ll get a new menu option to trigger a build instantly.

✅ Tip 3: Enable Proguard and Minification

In Player Settings, under Publishing Settings, you can enable:

  • Minify (Release): Shrinks code for smaller APKs.

  • Proguard: Obfuscates code to prevent reverse engineering.

✅ Tip 4: Use Android Logcat for Debugging

Unity 6 includes support for Android Logcat, which allows real-time logging from your device. To enable:

  1. Install the Android Logcat package from Unity Package Manager.

  2. Open Window > Analysis > Android Logcat.
