No listeners found for event <eventName>

Capacitor
1

I have a custom Java plugin attempting to communicate back to the Angular frontend, but it can not find the listener. I followed the official docs.

In my Java plugin, when the phone is plugged in and the Intent.ACTION_POWER_CONNECTED broadcast is emitted by the Android device, I call the CommunicateChargingStatus Java function to emit an event:

@CapacitorPlugin(name="PowerCommunication")
public class PowerCommunication extends Plugin {

  // Other functions

  public void CommunicateChargingStatus() {
        Log.w("POWER-COMMUNICATING", "Should be emitting a signal about charging status");
        JSObject ret = new JSObject();
        ret.put("value", "some value");
        notifyListeners("myPluginEvent", ret);
    }
}

On the Angular side, I get the Java plugin here:

interface PowerCommunicationInterface extends Plugin {}
export const PowerCommunicationPlugin = registerPlugin<PowerCommunicationInterface>("PowerCommunication");

And in my main app I have my the corresponding listener set up as such:

@Component({
    selector: 'app-root',
    templateUrl: 'app.component.html',
    styleUrls: ['app.component.scss']
})
export class AppComponent {

  constructor(
    // Fields
  ) {
    PowerCommunicationPlugin.addListener('myPluginEvent', (info: any) => {
      console.log(`Plugin Event: ${info}`)
    })
  }

  // Other logic...
}

However, when I plugin / unplug the power cable, I am getting the following log messages in Android Studio:

2024-05-24 11:18:05.500  6346-6346  POWER-COMMUNICATING     com.project.name       W  Should be emitting a signal about charging status

2024-05-24 11:18:05.500  6346-6346  Capacitor/...munication com.project.name       D  No listeners found for event myPluginEvent

Any idea why my Java code is unable to find the corresponding listener in Angular?
