Android - Firebase推送通知不起作用

问题描述：

我已经完全按照Google教程中的提示创建并设置了Firebase控制台。我也在我的项目中实施了服务。虽然我从Firebase控制台发送邮件，但未在我的应用中收到。当我尝试使用单个设备发送时，它显示“未注册的注册令牌”。Android - Firebase推送通知不起作用

这里是我的MyFirebaseInstanceIDService：

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService { 

    @Override 
    public void onTokenRefresh() { 

     //Getting registration token 
     String refreshedToken = FirebaseInstanceId.getInstance().getToken(); 
     System.out.println("TOKEN::" + refreshedToken); 
     //Displaying token on logcat 

     SmartApplication.REF_SMART_APPLICATION.writeSharedPreferences("regId", refreshedToken); 
//  SharedPreferences pref = getApplicationContext().getSharedPreferences(Config.SHARED_PREF, 0); 
//  SharedPreferences.Editor editor = pref.edit(); 
//  editor.putString("regId", refreshedToken); 
//  editor.commit(); 
    } 
}

这里是我的MyFirebaseMessagingService：

public class MyFirebaseMessagingService extends FirebaseMessagingService { 

    private static final String TAG = "MyFirebaseMsgService"; 
    private static int count = 0; 
    String TYPE = "type"; 

    @Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
     //Displaying data in log 
     //It is optional 
     System.out.println("data getting"); 
     Log.d(TAG, "Notification Message TITLE: " + remoteMessage.getNotification().getTitle()); 
     Log.d(TAG, "Notification Message BODY: " + remoteMessage.getNotification().getBody()); 
     Log.d(TAG, "Notification Message DATA: " + remoteMessage.getData().toString()); 

     //Calling method to generate notification 
     //remoteMessage.getNotification().getBody() 
     sendNotification(remoteMessage.getNotification().getTitle(), 
       remoteMessage.getNotification().getBody(), remoteMessage.getData()); 
    } 


    //This method is only generating push notification 
    //It is same as we did in earlier posts 
    private void sendNotification(String messageTitle, String messageBody, Map<String, String> row) { 
     PendingIntent contentIntent = null; 
     try { 
      Intent groupDetailIntent = new Intent(this, UnanimousHomeActivity.class); 

      contentIntent = PendingIntent.getActivity(this, (int) (Math.random() * 100), 
        groupDetailIntent, PendingIntent.FLAG_UPDATE_CURRENT); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
     NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
       .setSmallIcon(R.mipmap.ic_launcher) 
       .setContentTitle(messageTitle) 
       .setContentText(messageBody) 
       .setAutoCancel(true) 
       .setSound(defaultSoundUri) 
       .setContentIntent(contentIntent); 

     NotificationManager notificationManager = 
       (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
     notificationManager.notify(count, notificationBuilder.build()); 
     count++; 
    } 
}

由于图4天，我已经stucked，请别人帮我这里没有发现任何逻辑问题，一些不寻常的事情正在发生，而整合推动。

加服去之前，不得不派出由谷歌控制台测试推如果没有，则点击链接 - > https://console.firebase.google.com 然后选择您的项目。选择您的项目后，点击导航抽屉列表左侧的通知，并发送测试推送链接记得在发送测试推送您的设备应该在后台或关闭.. – yash786

尝试使用工具 - > Firebase - >云消息它可以帮助你找到缺失的论点 –

这些所有的事情我已经尝试过，但仍然没有成功。 –

public class MyFirebaseMessagingService extends FirebaseMessagingService { 

    private static final String TAG = MyFirebaseMessagingService.class.getSimpleName(); 

    @Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
     Log.e(TAG, "From: " + remoteMessage.getFrom()); 


     // Check if message contains a data payload. 
     if (remoteMessage.getData().size() > 0) { 
      Log.e(TAG, "Message data: " + remoteMessage.getData().toString()); 



     } 

     if (remoteMessage.getNotification() != null) { 
      Log.e(TAG, "Message data: " + remoteMessage.getData().toString()); 
      sendnotification(remoteMessage.getNotification().getBody()); 



     } 
    } 

    private void sendnotification(String body) { 

     Intent intent = new Intent(this,MainActivity.class); 
     intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 

     PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT); 

     Uri notificationsound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 

     NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
       .setSmallIcon(R.mipmap.ic_launcher) 
       .setContentTitle("Emoji Keyboard") 
       .setDefaults(-1) 
       .setContentText(body) 
       .setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 }) 
       .setSound(notificationsound) 
       .setAutoCancel(true) 
       .setContentIntent(pendingIntent); 

     NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE); 
     notificationManager.notify(0,notificationBuilder.build()); 
    } 


}

并在此之后在舱单补充一点：

<!-- Firebase Notifications --> 
     <service android:name=".services.MyFirebaseMessagingService"> 
      <intent-filter> 
       <action android:name="com.google.firebase.MESSAGING_EVENT" /> 
      </intent-filter> 
     </service> 

     <service android:name=".services.MyFirebaseInstanceIDService"> 
      <intent-filter> 
       <action android:name="com.google.firebase.INSTANCE_ID_EVENT" /> 
      </intent-filter> 
     </service> 
     <!-- ./Firebase Notifications -->

您已经成功获得令牌后，请确保您已经正确发送到您的服务器。

尝试recommended action为无效登记令牌：

检查登记的格式令牌传递给服务器。确保它与客户端应用程序从注册Firebase通知时收到的注册令牌相匹配。不要截断或添加其他字符。

欲了解更多信息，请参阅此documentation。

代码在我的应用程序工作正常

添加googleservices-JSON文件从火力创建应用文件夹，并清单中

<service 
      android:name=".MyFirebaseMessagingService"> 
      <intent-filter> 
       <action android:name="com.google.firebase.MESSAGING_EVENT"/> 
      </intent-filter> 
     </service> 
     <service 
      android:name=".MyFirebaseInstanceIDService"> 
      <intent-filter> 
       <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/> 
      </intent-filter> 
     </service>
