Setting Up Your Godot Project for Android Export
Before you can export your Godot game to Android, you need to configure your project properly. This involves setting up the Android build environment within Godot and preparing your project for export. Let’s start by setting up the build environment.
First, you have to download the Android SDK. Once you’ve installed it, you need to point Godot to the location of the SDK. You can do this within the Godot Editor by navigating to the Editor Settings:
Editor > Editor Settings > Export > Android
Here, you’ll set the paths for the ‘adb’, ‘jarsigner’, and ‘debug.keystore’. These are vital tools for building and signing your APK. Here’s an example of what the settings might look like:
adb: /path/to/your/android-sdk/platform-tools/adb jarsigner: /path/to/your/java/bin/jarsigner debug.keystore: /path/to/your/.android/debug.keystore
Next, let’s focus on setting up your Godot project with the basic export settings:
Project > Export > Add Export Preset > Android
You’ll need to fill out several settings, but let’s focus on the most essential:
– Unique Name: `com.yourcompany.yourgame`
– Version Code: `1`
– Version Name: `1.0`
– Release: `/path/to/your/release.keystore`
– Debug: `/path/to/your/debug.keystore`
With these settings configured, your Godot project is now ready for the next steps in the export process.
Managing Android App Permissions
For your game to leverage certain features or hardware of the Android device, you will need to declare the necessary permissions. This is done within the export settings. For example, if your game needs to access the Internet, you need to add the Internet permission:
Project > Export > Android > Permissions
Tick the checkbox for “Access Network State” and “Internet” permissions if they are required by your game. Additionally, you may want to deal with custom permissions that are not listed by default. You can do so by adding them manually to the `export_presets.cfg` file:
[preset.0] name="Android" ... custom_permissions="android.permission.CUSTOM_PERMISSION"
It’s very important to only add the permissions that are absolutely necessary, as each permission can affect the user’s trust and the functionality of your application.
Handling Screen Orientation and Other Features
Another essential consideration is the screen orientation. Depending on your game, you may want to lock the orientation to landscape or portrait. This setting is found in the same Android export settings dialog:
Project > Export > Android > Options > Screen Orientation
You can choose from “landscape”, “portrait”, “sensor landscape”, or “sensor portrait” depending on your needs. Here’s how you’d set it to landscape:
Additionally, Godot allows you to set various other features including immersive mode, unique icons per resolution, and more. For example, to enable immersive mode:
Project > Export > Android > Options
Then, select the “Immersive” checkbox. This will hide the navigation bar for a more immersive gaming experience on devices that support this feature.
Optimizing the Export for Different Architectures
Lastly, you want to make sure that your game runs smoothly on all types of Android devices. This involves setting up different APKs for various architectures like ARMv7 and ARMv8:
Project > Export > Android > Architectures
Select the appropriate checkboxes for your target architectures. For example, if you want to support both ARMv7 and ARMv8 devices, make sure both checkboxes are selected:
Remember that each architecture you add might increase the size of your APK, so balance the need for compatibility with the benefits of a smaller APK.
These basics should position you well on your journey to mastering Android exports in Godot 4. Stay tuned as we delve further into advanced exporting topics and tips in the following parts of our tutorial.
Advanced Export Concepts and Tips
Diving deeper into the export process, let’s address the management of expansion files, which is crucial for offering additional content or handling large game files for Android.
When your game’s size exceeds 100 MB, you may need to use APK Expansion Files (OBB). These files are hosted alongside your APK on the Play Store and are downloaded as part of the installation process. To set up OBB in Godot, configure the following:
Project > Export > Android > Expansion
Ensure you tick ‘Use Expansion (OBB)’, and specify the expansion file settings.
use_expansion="true" expansion_salt="1234567890" expansion_version="1"
Another significant aspect is managing Android-specific features, such as splash screens. Setting a custom splash screen ensures that your branding is visible during the game’s startup sequence. Modify these settings in the export preset:
Project > Export > Android > Images > Launcher Icons and Splash Images
You can add paths to your custom splash images:
Networking is another critical part of many games today. Configuring network settings to handle SSL certificates properly will ensure secure communications, especially if your game involves online multiplayer or services that require encryption. Include the required SSL certificates in your export:
Project > Export > Android > Keystore > Release
And set up the SSL certificates paths:
release_keystore="path/to/your/keystore" release_password="your_keystore_password" release_user="your_keystore_username" release_key_alias="your_key_alias"
Multidex support might be necessary for complex projects with numerous methods that exceed the Dex file’s limit. Enable Multidex with this setting if needed:
Project > Export > Android > Options > Format > Multidex
Check the “Use Multidex” option so your application can compile successfully:
Lastly, you can control the log level of your game’s output to help with debugging. Adjust this within the export settings if required:
Project > Export > Android > Debugging
Choose the appropriate log level for what you need to troubleshoot:
log_level="2" <!-- 0: None, 1: Error, 2: Warning, 3: Info, 4: Debug -->
As you can see, each of these settings opens up a new depth of customization for your Android exports, ensuring your game operates exactly as intended across various devices and user experiences.
With the power of these advanced settings, you’re now well-equipped to tackle the complexities of Android export in Godot 4.

Below are several code examples and settings that can enhance your game once it’s up and running on an Android device.
One critical performance setting is the application’s frame rate. Limiting the frame rate can save battery life on mobile devices. To do this, you can set the application’s frame rate in the ‘Engine’ section of the project settings:
Project > Settings > Engine > Target Frames Per Second
You can set it to a reasonable value like 60:
Customizing how your game interacts with Android’s back button can greatly improve user experience. You can capture the back button action and handle it within your game script:
if event is InputEventKey and event.pressed and event.scancode == KEY_ESCAPE:
# Handle the back button press.
For bigger projects, you might also want to define specific project settings for the Android platform using the ‘Feature Tags’. This allows for settings to only apply when the game is running on Android:
# Set Android-specific settings here
With Godot’s export templates, you can also include or exclude resources conditionally, which is particularly useful for controlling the size of your APK. To include assets only in the Android export, you can use the ‘Feature Tags’ in the ‘Resources’ tab of the export preset:
Project > Export > Android > Resources > Filters to export non-resource files/folders
Set resources to include with “Android” tag:
Sometimes, you’ll want to protect your game from unwanted copying by enabling ProGuard or using other obfuscation methods. Enable ProGuard using the export settings:
Project > Export > Android > Security > Use ProGuard
Tick the ‘Use ProGuard’ checkbox to add an extra layer of security:
For an extra touch, adding custom user agents for web-based requests within your game shows professionalism. Define a custom user agent for the HTTPClient nodes:
var http_client = HTTPClient.new()
Lastly, localization is vital for reaching a wider audience. Godot makes it relatively straightforward to configure your game for different languages. Begin by adding your translations:
Project > Project Settings > Localization > Translations
Add the paths to the translation resources:
The use of these advanced settings and code snippets will enrich the user’s experience and ensure your game performs well on Android.entario y asegurarse de que su juego funciona bien en Android.
