当我在 Android 上收到推送通知时，我收到以下错误。我似乎无法找到任何有关它的信息。任何人都可以帮忙吗？我真的很茫然。

FirebaseMessagingService.java

public class FirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "FCM Service";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        try {
            sendNotification(remoteMessage);
        } catch (Exception e) {

    }


    private void sendNotification(final RemoteMessage remoteMessage) throws Exception {

        Calendar c = Calendar.getInstance();

        String strDate = sdf.format(c.getTime());

        String contentTitle = "New Push Message";
        String contentText = "Received at " + strDate;

        Utilities.sendNotification(getApplicationContext(),
                getNotificationIcon(),
                contentTitle,
                contentText,

                HomeActivity.class,
                Utilities.getNotificationId(getApplicationContext()));

    }

实用程序

 public static void sendNotification(Context appContext,
                                            int icon,
                                            String title,
                                            String msg,
                                            long when,
                                            Class<? extends Context> classToLaunch,
                                            long processId) {

            //Define notification msg
            Intent launchIntent = null;

            if (classToLaunch != null) {
                launchIntent = new Intent(appContext, classToLaunch);
            } else {
                launchIntent = new Intent();
            }

            // This is dummy data for just differentiate Pending intent
            // only set value that is check IntentFilter
            launchIntent.addCategory("CATEGORY" + new Date(System.currentTimeMillis()));
            launchIntent.addFlags((int) System.currentTimeMillis());
            launchIntent.setAction("ACTION" + new Date(System.currentTimeMillis()));

            // also make launch mode to singleTop in manifest for that activity
            launchIntent.setFlags(
                    Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK |
                            Intent.FLAG_ACTIVITY_NEW_TASK);

            // intent to be launched when click on notification
            PendingIntent pendingIntent = PendingIntent.getActivity(appContext,
                    0,
                    launchIntent,
                    PendingIntent.FLAG_UPDATE_CURRENT);

            //Instantiate the notification
            NotificationCompat.Builder builder = new NotificationCompat.Builder(appContext); //(icon, msg, when);
            builder.setContentTitle(title);
            builder.setSmallIcon(icon);
            builder.setWhen(when);
            builder.setTicker(msg);
            builder.setContentText(msg);
            builder.setContentIntent(pendingIntent);
            builder.setAutoCancel(true);
            builder.setDefaults(Notification.DEFAULT_LIGHTS);
            builder.setDefaults(Notification.DEFAULT_SOUND);


            NotificationManager notificationManager = (NotificationManager) appContext.getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManager.notify((int) processId, builder.build());
        }

HomeActivity

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);

        if (getIntent().getExtras() != null) {
            for (String key : getIntent().getExtras().keySet()) {
                Object value = getIntent().getExtras().get(key);
                if (BuildConfig.DEBUG_APPLICATION) {
                    Log.d(TAG, "Key: " + key + " Value: " + value);
                }
            }
        }
}

最佳答案

您应该保持 Firebase 库版本和 Google Play 服务库相似。所以将 Firebase 库的版本号更新为 10.2.1:

变化:

compile 'com.google.firebase:firebase-core:10.0.1'
compile 'com.google.firebase:firebase-messaging:10.0.1'

收件人:

compile 'com.google.firebase:firebase-core:10.2.1'
compile 'com.google.firebase:firebase-messaging:10.2.1'
