How can I implement a feature that allows players to change the game’s app icon on Android using Godot?

Implementing Dynamic App Icon Change on Android with Godot

To enable players to change the game’s app icon on Android using the Godot Engine, follow these steps:

Step 1: Prepare Multiple Icon Sets

• Create different icon resources for each icon variation you want to offer. Ensure that each icon conforms to the required sizes and formats as specified by Android guidelines.
• Organize these resources in the res directory of your Godot project, maintaining a clear naming convention for each.

Step 2: Leverage Android Manifest

Update the AndroidManifest.xml to handle different launcher activities based on the selected icon. Each activity should point to a different icon resource. Here’s an example snippet:

Your chance to win awaits you!

<activity-alias android:label="App" android:icon="@mipmap/icon_variant1" android:name=".MainActivityVariant1" android:targetActivity=".MainActivity" />

Step 3: Modify export_presets.cfg

Modify the export_presets.cfg file to ensure that Godot exports the necessary resources for each icon option. Use the following template:

[preset.0.options]
custom_template/pack - path/to/pack1.touchscene

Step 4: Deployment Using Gradle

• Configure your Gradle build scripts to include different icon sets based on build types. Reference specific icon names and paths dynamically within these scripts to allow runtime changes without re-deployment.

Step 5: Implement Icon Change Logic

In your game logic, provide a method to switch between these launcher activities. This can often be achieved through Java or Kotlin by directing users to the appropriate Intent:

Intent intent = new Intent(this, MainActivityVariant1.class);
startActivity(intent);
finish();

Step 6: Testing and Validation

• Thoroughly test the app to ensure that icon changes are applied correctly across different devices and configurations.
• Validate app behavior post-icon change to ensure user experience remains seamless.
