更改软件包名称后FCM无法正常工作 [英] FCM is not working after changing the package name

问题描述

我正在尝试开发一个将使用Firebase显示通知的应用程序.Firebase通知在我的设备上运行正常，但在其他设备上不运行，但是更改软件包名称后， FCM 不再起作用.我尝试在 Firebase控制台中添加相同的程序包名称，但仍然是相同的问题

I am trying to develop an application that will show notifications using Firebase. Firebase notification was working fine on my device but its not working on other devices but after changing the package name, FCM is not working anymore. I try to add same package name in Firebase Console but still the same issue

这是我的代码

Manifest.xml

   <service
             android:name=".Model.Services.MyFirebaseMessagingService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>
   <meta-data
            android:name="com.google.firebase.messaging.default_notification_icon"
            android:resource="@drawable/icon" />
    <meta-data
            android:name="com.google.firebase.messaging.default_notification_color"
            android:resource="@color/colorAccent" />
    <meta-data
            android:name="firebase_messaging_auto_init_enabled"
            android:value="false" />
    <meta-data
            android:name="firebase_analytics_collection_enabled"
            android:value="false" />

MyFirebaseMessagingService.kt

class MyFirebaseMessagingService : FirebaseMessagingService() {
private var mNotificationManager: NotificationManager? = null
private var mBuilder: NotificationCompat.Builder? = null
var NOTIFICATION_CHANNEL_ID = "10001"
var notificationPref:SharedPreferences? = null

override fun onMessageReceived(message: RemoteMessage?) {
    Log.d("FirebaseMessage", "message")
    notificationPref = getSharedPreferences("Notification" , Context.MODE_PRIVATE)
    message?.data?.isNotEmpty()?.let {
        Log.d("FirebaseMessage", "Message data payload: " + message.data)
    }
    message?.notification?.let {
        Log.d("FirebaseMessage", "Message Notification Body: ${it.body}")
        val editor = notificationPref?.edit()
        var count = notificationPref?.getInt("notification_count" , 0)
        Log.d("FirebaseMessage", "Message Notification count: $count")
        count = count?.plus(1)
        editor?.putInt("notification_count" , count!!)
        editor?.apply()
        sendNotification(it.body)
    }

}

private fun sendNotification(notification: String?) {
    val resultIntent = Intent(this, Dashboard::class.java)
    resultIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)

    val resultPendingIntent = PendingIntent.getActivity(
        this,
        0 /* Request code */, resultIntent,
        PendingIntent.FLAG_UPDATE_CURRENT
    )

    mBuilder = NotificationCompat.Builder(this)
    mBuilder!!.setSmallIcon(R.mipmap.ic_launcher)
    mBuilder!!.setContentTitle("Notification")
        .setContentText(notification)
        .setAutoCancel(false)
        .setSound(Settings.System.DEFAULT_NOTIFICATION_URI)
        .setContentIntent(resultPendingIntent)

    mNotificationManager = this.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        val importance = NotificationManager.IMPORTANCE_HIGH
        val notificationChannel =
            NotificationChannel(NOTIFICATION_CHANNEL_ID, "NOTIFICATION_CHANNEL_NAME", importance)
        notificationChannel.enableLights(true)
        notificationChannel.lightColor = Color.RED
        notificationChannel.enableVibration(true)
        notificationChannel.vibrationPattern = longArrayOf(100, 200, 300, 400, 500, 400, 300, 200, 400)
        assert(mNotificationManager != null)
        mBuilder!!.setChannelId(NOTIFICATION_CHANNEL_ID)
        mNotificationManager!!.createNotificationChannel(notificationChannel)
    }
    assert(mNotificationManager != null)
    mNotificationManager!!.notify(0 /* Request Code */, mBuilder!!.build())
}
}
