Не удается заставить трансляции работать с собственным модулем android (файлом AAR) в Unity

Идея заключалась в том, что мне нужен был GPS в фоновом режиме для проекта Unity. Он предназначен для того, чтобы узнать, находится ли пользователь рядом с «информационной точкой» во время пеших походов по определенным маршрутам. Для этого мы решили (поскольку нам нужно было получать довольно частые обновления GPS) использовать геозону. Я создал собственный модуль в студии Android и поместил файл AAR в единое целое. однако широковещательный приемник никогда не запускается. Я начал с учебника по фоновой трансляции Android как базового c шаблона (https://developer.android.com/training/location/geofencing.html). Код в итоге выглядел так:

Bridge. java

    }

Манифест выглядит так:

AndroidManifest. xml

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.BrabantWater.mynativemodulegps">
    
        <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
        <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
    
        <application>
            <receiver android:name=".GeofenceBroadcastReceiver" />
        </application>
    </manifest>

На стороне Unity я создал класс, который вызывает методы моста и изменил манифест, чтобы убедиться, что я получил доступ к местоположению.

AndroidCaller.cs 

#if UNITY_ANDROID
//basic imports.
using UnityEngine;

public class AndroidCaller : MonoBehaviour
{
    AndroidJavaClass unityPlayerClass;
    AndroidJavaObject unityActivity;
    AndroidJavaObject bridge;
    object[] parameters;

    void Start()
    {
        //just done for testing purposes
        CallNativePlugin();
    }
    //method that calls our native plugin.
    public void CallNativePlugin()
    {
        // Retrieve the UnityPlayer class.
        unityPlayerClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");

        // Retrieve the UnityPlayerActivity object ( a.k.a. the current context )
        unityActivity = unityPlayerClass.GetStatic<AndroidJavaObject>("currentActivity");

        // Setup the parameters we want to send to our native plugin.    
        parameters = new object[4];
        parameters[0] = unityActivity;
        parameters[1] = "Title";
        parameters[2] = "ContentText";
        parameters[3] = "Description";

        // Retrieve the "Bridge" from our native plugin.
        // ! Notice we define the complete package name.              
        bridge = new AndroidJavaObject("com.BrabantWater.mynativemodulegps.Bridge", parameters);

        // Call addGeoFence in bridge, with our parameters.
        bridge.Call("addGeoFence", "id", 51.461059, 4.310962);
        bridge.Call("addGeoFence", "id2", 51.451459, 4.329905);
        bridge.Call("GeoFenceCompleted");
    }
}
#endif

AndroidManifest. xml (в Unity project) 

<?xml version="1.0" encoding="utf-8"?>
<!-- GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN-->
<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.unity3d.player"

    <application>
        <receiver android:name="com.BrabantWater.mynativemodulegps.GeofenceBroadcastReceiver" />
        <activity android:name="com.unity3d.player.UnityPlayerActivity"
                  android:theme="@style/UnityThemeSelector">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
        </activity>
    </application>
    
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
    <uses-permission android:name="android.permission.CAMERA" />   
</manifest>

После большого количества тестов с использованием logcat я не мог понять, почему onReceive никогда не запускался. Вот так я и застрял.

Никогда не думал, что сам получу ответ. Очевидно, вы должны использовать полное имя в приемнике как для xml in unity, так и для android studio, например: <receiver android:name="com.BrabantWater.mynativemodulegps.GeofenceBroadcastReceiver" />
