Install Android Studio
Android Studio is the official integrated development environment (IDE) for Android app development, and it's necessary for building, testing, and publishing Unity APKs for Android. In this section, we will walk you through the process of installing Android Studio and configuring it to work with Unity, so you can start creating and publishing your Unity-based games and applications on the Android platform.
Install on Windows/ MacOS/ Ubuntu
Installation can be done using the link- https://developer.android.com/studio on different operating systems, namely- Windows, MacOS, and Ubuntu.
Additionally, it's worth checking if Java Development Kit (JDK) has been installed on your machine. JDK is essential to run and develop Java applications such as Android Studio. You can obtain the JDK from this page: https://www.oracle.com/java/technologies/javase-downloads.html
Install Unity Editor
Once you have downloaded the Unity Hub, you'll need to install the Unity editor. For new projects, you can select any version of the editor. However, if you're working on a project that has been created by someone else, it's important to install the exact version of the editor that the project was made with. You can access older versions of the editor at the following link: https://unity.com/releases/editor/archive.
Install Android Modules in Unity
To include the Android modules in Unity, you can follow these steps:
- Open Unity editor and click on the "Installs" tab on the sidebar.
- Click the "Settings" button on the Unity editor.
- From the "Settings" window, click on "Add Modules" button.

To begin creating an APK for Android, we will first export the Unity code. First, install the Unity editor and locate your Unity project file. Then, within the Unity editor, navigate to the "File" menu and select "Build Settings" or alternatively, you can use the shortcut key combination "Ctrl+Shift+B" on a Windows device as shown in Fig. 2 below.
If your current platform is not set to Android, please select Android and switch to it. Before exporting, make sure to click the "Export" button. Additionally, don't forget to check the "Export Project" checkbox (Fig. 3).
Step 2: Import the exported file into Android Studio and build an APK for Android
To create an APK in Android Studio, follow these steps:
- Open Android Studio.
- Go to the "Build" menu and select "Generate Signed APK."
- Follow the prompts to sign and export your APK. It will be saved in the project's "build/outputs/apk" folder.
Note: A signed APK is required to publish your app on the Google Play store, as it guarantees the authenticity and integrity of your app by using a digital signature.
You can follow the below mentioned steps to generate a signed APK in Android Studio. (Fig. 4).
To create a signed APK in Android Studio, follow these steps:
- Open Android Studio.
- Go to the "Build" menu and choose "Generate Signed Bundle / APK."
- Select "APK" as the output type and click the "Next" button.
- Choose the signing configuration and keystore that you want to use. If you don't have any, you can create a new one by clicking the "Create New" button.
- Click the "Next" button.
- Provide the password for the keystore and choose the private key for signing.
- Click the "Finish" button.
The APK will be saved in the project's "build/outputs/apk" folder.
Once you have completed the steps above, Android Studio will create a signed APK and save it to the designated location. This APK can be used to publish your app on the Google Play Store or distribute it to testers or end users. Once the APK is generated, you can test it by installing it on a physical Android device or an Android Virtual Device (AVD).
Conclusion
In conclusion, creating an APK for an Android device from Unity is a straightforward process that can be completed using Android Studio. By following the steps outlined above, developers can easily generate a signed APK that can be used to publish their app on the Google Play Store or distribute it to testers and users.
From a business perspective, having a mobile app on the Android platform can greatly expand your reach and provide an additional avenue for revenue. With the ability to easily create an APK, businesses can quickly and efficiently develop and release their app to the Android market.
To take advantage of this opportunity, you may take initiative and create an APK for your Unity app on the android platform. This will help you to reach more customers, increase revenue and create a stable source of income.
