   The Godot Android library is `hosted on MavenCentral <https://central.sonatype.com/artifact/org.godotengine/godot>`_, and updated for each release.
 
 3. Create `GodotAndroidPlugin <https://github.com/m4gr3d/Godot-Android-Plugin-Template/blob/a01286b4cb459133bf07b11dfabdfd3980268797/plugin/src/main/java/org/godotengine/plugin/android/template/GodotAndroidPlugin.kt#L10>`_, an init class for the plugin extending `GodotPlugin <https://github.com/godotengine/godot/blob/0a7f75ec7b465604b6496c8f5f1d638aed250d6d/platform/android/java/lib/src/org/godotengine/godot/plugin/GodotPlugin.java#L80>`_.

The name called from GDScript **must match the method name exactly**. There is **no** coercing ``snake_case`` to ``camelCase``. For example, from GDScript:
 
-          if Engine.has_singleton("MyPlugin"):

-              print(singleton.myPluginFunction("World"))

+                var singleton = Engine.get_singleton("MyPlugin")
+                print(singleton.myPluginFunction("World"))
 
     - If the plugin uses `signals <https://docs.godotengine.org/en/stable/getting_started/step_by_step/signals.html>`_, the init class must return the set of signals used by overriding `GodotPlugin::getPluginSignals() <https://github.com/godotengine/godot/blob/fa3428ff25bc577d2a3433090478a6d615567056/platform/android/java/lib/src/org/godotengine/godot/plugin/GodotPlugin.java#L302>`_. To emit signals, the plugin can use the `GodotPlugin::emitSignal(...) method <https://github.com/godotengine/godot/blob/0a7f75ec7b465604b6496c8f5f1d638aed250d6d/platform/android/java/lib/src/org/godotengine/godot/plugin/GodotPlugin.java#L317>`_.
