App abstürzt, wenn Benachrichtigung an ein einziges Gerät zu senden versuchen, von Feuerbasis

Question

Ich versuche Firebase Benachrichtigung an ein einziges Gerät zu senden und dass ich die FCM registration token mit dem Code unten Introduction:

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService { 

    private static final String TAG = "MyFirebaseIIDService"; 

    /** 
    * Called if InstanceID token is updated. This may occur if the security of 
    * the previous token had been compromised. Note that this is called when the InstanceID token 
    * is initially generated so this is where you would retrieve the token. 
    */ 
    // [START refresh_token] 
    @Override 
    public void onTokenRefresh() { 
     // Get updated InstanceID token. 
     String refreshedToken = FirebaseInstanceId.getInstance().getToken(); 
     Log.d(TAG, "Refreshed token: " + refreshedToken); 

     // TODO: Implement this method to send any registration to your app's servers. 
     sendRegistrationToServer(refreshedToken); 
    } 
    // [END refresh_token] 

    /** 
    * Persist token to third-party servers. 
    * 
    * Modify this method to associate the user's FCM InstanceID token with any server-side account 
    * maintained by your application. 
    * 
    * @param token The new token. 
    */ 
    private void sendRegistrationToServer(String token) { 
     // Add custom implementation, as needed. 
    } 
} 

Hier MyFirebaseMessagingService.java Datei Code:

public class MyFirebaseMessagingService extends FirebaseMessagingService { 

    private static final String TAG = "MyFirebaseMsgService"; 

    /** 
    * Called when message is received. 
    * 
    * @param remoteMessage Object representing the message received from Firebase Cloud Messaging. 
    */ 
    // [START receive_message] 
    @Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
     // TODO(developer): Handle FCM messages here. 
     // If the application is in the foreground handle both data and notification messages here. 
     // Also if you intend on generating your own notifications as a result of a received FCM 
     // message, here is where that should be initiated. See sendNotification method below. 
     Log.d(TAG, "From: " + remoteMessage.getFrom()); 
     Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody()); 

     sendNotification(remoteMessage.getNotification().getBody()); 
    } 
    // [END receive_message] 

    /** 
    * Create and show a simple notification containing the received FCM message. 
    * 
    * @param messageBody FCM message body received. 
    */ 
    public void sendNotification(String messageBody) { 
     Intent intent = new Intent(this, SettingsActivity.class); 
     intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, 
       PendingIntent.FLAG_ONE_SHOT); 

     Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
     NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
       .setSmallIcon(R.mipmap.ic_launcher) 
       .setContentTitle("FCM Message") 
       .setContentText(messageBody) 
       .setAutoCancel(true) 
       .setSound(defaultSoundUri) 
       .setContentIntent(pendingIntent); 

     NotificationManager notificationManager = 
       (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 

     notificationManager.notify(0 /* ID of notification */, notificationBuilder.build()); 
    } 
} 

das Problem ist, dass, wenn ich versuche, Firebase Benachrichtigung zu senden, während die App noch auf dem Bildschirm ist, wird es mehrere Male gibt diesen Fehler Absturz: java.lang.IllegalArgumentException: URI: content://com.android.contacts/phone_lookup/?encrypt=%20%3C%202, calling user: com.android.mms:10015, calling package:com.android.mms

Ich weiß wirklich nicht, was hier falsch läuft!

Bitte lassen Sie es mich wissen.

Versuchen Debuggen onMessageReceived() müssen Sie immer remoteMessage.getNotification() = null, wenn Sie keine Benachrichtigung Block in Ihre Push senden:

@Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
     Log.d(TAG, "From: " + remoteMessage.getFrom()); 
     // Check if remoteMessage.getNotification() == null ?? 
     Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody()); 

     sendNotification(remoteMessage.getNotification().getBody()); 
    } 

Auch Ihre Frage mit voller Fehlerprotokoll aktualisieren.

Stellen Sie nur sicher, dass die Zeile "apply plugin: 'com.google.gms.google-services'" in der Datei build.gradle Ihrer App ganz unten in der Datei build.gradle liegt. Andernfalls stürzt die App möglicherweise ab, wenn eine Nachricht empfangen wird.
