android.app.RemoteServiceException：startForeground 的错误通知

我正在尝试按如下方式启动前台服务：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

    NotificationChannel chan = new NotificationChannel(
            getApplicationContext().getPackageName(),
            "My Foreground Service",
            NotificationManager.IMPORTANCE_LOW);
    chan.setLightColor(Color.BLUE);
    chan.setLockscreenVisibility(Notification.VISIBILITY_SECRET);

    NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    assert manager != null;
    manager.createNotificationChannel(chan);

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder( 
            this, "MyChannelId");
    Notification notification = notificationBuilder.setOngoing(true)
            .setSmallIcon(R.mipmap.my_icon)
            .setContentTitle("App is running on foreground")
            .setPriority(NotificationManager.IMPORTANCE_LOW)
            .setCategory(Notification.CATEGORY_SERVICE)
            .setChannelId("MyChannelId")
            .build();

    startForeground(1, notification);
}

此解决方案适用于 Android 8.0 模拟器。但是我在 Android 8.1、9.0 和 10.0 模拟器上遇到以下错误。

重复的类 Koin org.koin 和 io.insert-koin

我正在使用两个库，它们依赖于两个不同版本的 Koin。

其中一个库具有org.koin:koin-android:2.0.1 依赖项，另一个库具有io.insert-koin:koin-core-jvm:3.0.1依赖项。

在编译时，我收到了大量的重复类错误，如下所示，

Duplicate class org.koin.android.BuildConfig found in modules jetified-koin-android-2.0.1-runtime (org.koin:koin-android:2.0.1) and jetified-koin-android-3.0.1-runtime (io.insert-koin:koin-android:3.0.1)

当我尝试排除其中之一时，如下所示，

configurations {
    all { 
        exclude group: "io.insert-koin", module: "koin-android"
        exclude group: "io.insert-koin", module: "koin-core-jvm"
    }
