If you are receiving device token and you have server api key then check your code working properly or not using pushtry . it will give error like Invalid Registration, 404 Error etc if you have done any mistake in your code. and for implementation of FCM, you can follow this tutorial- FCM Tutorial

One more thing i have notice in your build.gradlefile there is no any applicationId "Package Name" in defaultConfig. I am not sure but this is package name and used when we create project on firebase console (Project name with package)

Most likely your notifications are not showing due to Android Oreo new notifications model which requires to specify channels definitions in order to build and show notifications. Also in your app.gradle, you are targeting android version 26 which is Android Oreo, so you will have to implement the code below either way.

It is easy to adopt. all you need to do is:

1. define a notification channel in your YourApplicationClass.onCreate()

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

            NotificationChannel chan1 = new NotificationChannel(
                YOUR_DESIRED_CHANNEL_ID_STRING,
                YOUR_DESIRED_CHANNEL_LABEL_STRING, 
                NotificationManager.IMPORTANCE_DEFAULT);

            chan1.setDescription(YOUR_DESIRED_CHANNEL_DESC_STRING);//OPTIONAL
            chan1.setLightColor(Color.BLUE);//OPTIONAL     
            chan1.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);//OPTIONAL
            chan1.setShowBadge(true);//OPTIONAL

            getManager().createNotificationChannel(chan1);
        }

2. replace you notification builder with this constructor

    NotificationCompat.Builder builder=
new NotificationCompat.Builder(this, YOUR_DESIRED_CHANNEL_ID_STRING);

Good to know that you can define more than one channel with different properties targeting Android Oreo and higher

Solution 3

If you take a look at this doc You don't seem to have a service that extends FirebaseInstanceIdService to manage the token creation/rotation. Here is a example code. The token you need to send the push notifications to a specific device is received by this class.

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

EDIT:

Okay, this error is bugging me now. I looked at your dependency tree and I see you're repeating some of them. For example you have three version of:

compile 'com.android.support:appcompat-v7:25.4.0'

Maybe you should clear that out to the newest version, or match it with the working version. Also you're using the new gradle plugin, but you haven't updated your depedencies to use implementation instead of compile in most cases, maybe try that as well? Here's why you should do it.

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
//compile project(path: ':backend', configuration: 'android-endpoints')

Also, update your dependencies and use implementation instead of compile:

// this help to start FCM service in background when phone restart.

Add receiver in Manifest.xml

<uses-permission android:name="android.permission.WAKE_LOCK" />
<receiver android:name=".OnBootBroadcastReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
</receiver>

OnBootBroadcastReceiver.class

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class OnBootBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent i = new Intent("com.examle.FirebaseMessagingReceiveService");
        i.setClass(context, FirebaseMessagingReceiveService.class);
        context.startService(i);
    }
}

Hope you know the types of notifications, For sending notification you have to use custom server or something like postman , for more information, please refer the answer of these question :

How to handle notification when app in background in Firebase

Anyways, you have to call handleIntent(Intent intent) method in your FirebaseMessagingService in order to call onMessageReceived() method..

Here is my complete working code, notification-when-app-in-background-in-firebase.

build.gradle : 

apply plugin: 'com.android.application'

    compileSdkVersion 26
    buildToolsVersion '26.0.3'
    defaultConfig {
        applicationId "com.abc.xyz"

        targetSdkVersion 26
        multiDexEnabled true
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    dexOptions {
        javaMaxHeapSize "4g"
    }
}

dependencies {

    I want to make a simple notification feature in my app. I followed this YouTube video and both of these Firebase documentation URLs 1 and 2 plus the Firebase tool assistant in Android Studio (which says I'm connected to Firebase). For some reason, following these steps and documents on my older app (which code is posted below), it won't allow me to receive notifications. However, if I follow the same steps on a brand new app it works perfectly. I tested both apps on the same physical device and environment in the background, active and terminated states. Every time the new demo app I created works with no issue but my older app which I want notifications in does not work. Both tested without getting the device ID. I do not even get any error logs or any TAG log. I think one of my compiled projects is interfering, not sure exactly what but I might have to look there.

    I also checked out all these SO posts already: 123 and more

    PS. I removed my package name below, I checked multiple times on FireBase and they match so I know that is not the issue. However, my new demo app's FireBase shows that my app connected but my older app's FireBase did not. Also, I've set a bounty before and still running into the same issue.

    Here's my problematic code:

    Notification.java (its a service like the documentation asks)

    public class Notification extends FirebaseMessagingService {
public Notification() {
}
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    showNotification(remoteMessage.getData().get("message"));

    Log.d("FMC", "Message Notification Body: " + remoteMessage.getNotification().getBody());
}

private void showNotification(String message) {
    Intent i=new Intent(this, SplashScreen.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent=PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder builder=new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentTitle("FCM TITLE").setContentText(message)
            .setSmallIcon(R.drawable.pt_icon)
            .setDefaults(android.app.Notification.DEFAULT_ALL)
            .setContentIntent(pendingIntent);

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

    Notice I do not even get a log in the notification.java above.

    I dont have it in my quick app that i made and it works
  • Levi Moreira
    Levi Moreira about 6 years
    in the video you said you used, around 11:03 the guy teaches how to create the FirebaseInstanceIdService, did you use the video for the quick app?
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    No the ID service is used to gain the token to subscribe to topic notifications but i just want to send a notification to everyone, I will play with topics and more after
  • Levi Moreira
    Levi Moreira about 6 years
    Okay, if you're not sending the notification to the device via token, how are you sending it?
  • Levi Moreira
    Levi Moreira about 6 years
    Because the ID service is also used to generate the token to send to the server for communication. For example, if I want my app to have push notifications from firebase I save that token to the real time database and use it to direct messages to my device.
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    Thats if you want to send to a single device or use the token to subscribe the phone to a notification topic. I want to send a notification to everyone like in the quick app i made. Do you want to see the working code?
  • jessica
    jessica about 6 years
    1. Have you check the type of notification (message or Data) becuase in your onMessageReceived you have handle only data message. try to print log in this message. 2. if you have implement GCM in previous project and GCM dependencies, may be some confict with fcm.
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    Every time I test I check my logs for "FCM" and it has never shown up. Also, I believe I used GCM awhile ago, can you help me point out how to get rid of it?
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    I made the Firebase project, added the .json, then connected my project from the Assistant Tool
  • jessica
    jessica about 6 years
    when you send notification to device, try to get the log, this will help.. and check that fcm token generate or not, if token is valid then only you receive notification.
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    Again every time I test anything I always check my logs for "FMC" and I do not want to send the notification to my device only, I want to send a notification to everyone.
  • jessica
    jessica about 6 years
    first check with your device fcm token, you can use advance rest client chrome extension to send notification
  • jessica
    jessica about 6 years
    check from this below link stackoverflow.com/questions/43816663/…
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    I removed the package name it has private info but I connected it with the Firebase Assistant Tool in Android Studio and on the Firebase website. Everything says its connected. Also, I did add the .json file.
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    Just posted it, check above
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    I test by sending notifications while the app is in background and removed from activity. My demo app works while the main app doe not.
  • tushar
    tushar about 6 years
    if you want to send notification to all mobile devices then you have to store device id of mobile to your server and then notification will come to all devices.
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    Thats not true because I recreated the steps on a new app which works fine without storing device ID's. Check above for updated question.
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    If that's the case shouldn't my new app not work because it also targets Android Oreo and it doesn't follow the new notifications model?
  • Bassel Mourjan
    Bassel Mourjan about 6 years
    you might be facing a different kind of problem or bug, but I am 100% sure that without specifying channels, your app will fail to show notifications on devices running android O (26)... are you testing both of your apps on the same device/android version? also do both apps have the same code implementation? (maybe I could help further)
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    I do test both apps on the same device and both apps have all there respected code above
  • Bassel Mourjan
    Bassel Mourjan about 6 years
    2 silly questions but helps debugging: - did you place the same json file in both projects? - how are you sending your notifications to devices? firebase console? after a second look.. your code looks fine
  • Lazar Kukolj
    Lazar Kukolj about 6 years
    I have their .json file for each project and I'm sending a notification via firebase console. Exactly that's why I am super stuck :/
  • Bassel Mourjan
    Bassel Mourjan about 6 years
    In that case, you are left with one of the following: 1 make sure not to use the same push ID for both apps cause its unique by app and not by device. 2 make sure that you are using the correct and up-to-date Push ID since push Ids get changed every now and then. Therefore I suggest that you implement FirebaseInstanceIdService (firebase.google.com/docs/reference/android/com/google/fireb‌​ase/…) which I fail to see implemented in your code.

    this answer was auto-selected for the +25. This answer did not solve my issue.
  • Levi Moreira
    Levi Moreira almost 6 years
    this is a wild guess, but have you tried make the manifest equal. I mean, just testing removing your other activities and leaving just the launcher activity like in the app that's working? The same with the build.gradle, you two options (besides the dependencies) that you don't have in the other app dexOptions, lintOptions and productFlavors
  • Morteza Rastgoo

    @aj0822ArpitJoshi May I have another question for you? I have a project which testing from Firebase console works fine on debug but release version with proguard rules set not working. I test it using pushtry and it works fine. any opinion what whould be the problem?
