FCM notification doesn't show notification pop up in background

I'm using firebase cloud function for showing notification in my app and that working perfectly only issue I'm facing is when app is closed or in background notification doesn't show pop up.
Heads up notifications are used in app and I do get the notification but notification doesn't pop up as it do while app is in foreground.I have set the Priority to high for both channel and notification but still it doesn't work.
My Service Class :
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Log.d("msg", "onMessageReceived: " + remoteMessage.getData().get("message"));
Intent intent = new Intent(this, WebViewActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
String channelId = "Default";
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.app_logo)
.setContentTitle(remoteMessage.getNotification().getTitle())
.setContentText(remoteMessage.getNotification().getBody())
.setAutoCancel(true).setContentIntent(pendingIntent)
.setDefaults(DEFAULT_SOUND | DEFAULT_VIBRATE)
.setPriority(Notification.PRIORITY_MAX);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId, "Default channel", NotificationManager.IMPORTANCE_HIGH);
channel.setShowBadge(true);
channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
manager.createNotificationChannel(channel);
}
manager.notify(0, builder.build());
}
Manifest
<application

android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"

</service>
</application>
Any help would be appreciated. Thanku

As you are already setting the Priorities it seems like you are not adding the metadata for the notification and when the app is in the background it won't get any data that's why it only showing the pop up in the foreground
add these metadata in your code:
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="#drawable/ic_stat_ic_notification" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="#color/colorAccent" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="#string/default_notification_channel_id" />
Also, you can see Google Cloud Messaging documentation for more details
Happy coding

I have faced the same issue. I have followed the official documentation from the firebase and now notifications are working fine. Follow this link
.

Have you created FirebaseMessage Instance() in your Activity?

Error : Use of fullScreenIntent requires the USE_FULL_SCREEN_INTENT permission

I'm using notifications with fullscreen my code works find in Oreo and below version
But when i'm running android-Q I'm getting below exception
Use of fullScreenIntent requires the USE_FULL_SCREEN_INTENT permission
I'm using setFullScreenIntent() for notifications with fullscreen
Here is my code
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, "123");
notificationBuilder.setAutoCancel(true)
.setColor(ContextCompat.getColor(this, R.color.colorAccent))
.setContentTitle(getString(R.string.app_name))
.setContentText("Test")
.setDefaults(Notification.DEFAULT_ALL)
.setWhen(System.currentTimeMillis())
.setFullScreenIntent(pendingIntent,true)
.setSmallIcon(R.drawable.ic_launcher_background)
.setAutoCancel(true);
mNotificationManager.notify(1000, notificationBuilder.build());

Here is the answer
Now wee need to add <uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT" /> permission in manifest file
Permissions changes for fullscreen intents
Apps that target Android Q or higher and use notifications with fullscreen intents must request the USE_FULL_SCREEN_INTENT permission in their app's manifest file. This is a normal permission, so the system automatically grants it to the requesting app
SAMPLE CODE
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="xxx.xxx.xxx">
<uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT" />
<application
android:allowBackup="true"

android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

setFullScreenIntent
An intent to launch instead of posting the notification to the status bar. Only for use with extremely high-priority notifications demanding the user's immediate attention, such as an incoming phone call or alarm clock that the user has explicitly set to a particular time. If this facility is used for something else, please give the user an option to turn it off and use a normal notification, as this can be extremely disruptive.

Why does FirebaseMessagingService.onMessageReceived() not getting called?

In my android project I'm including Firebase Cloud Messaging. I'm on SDK 21 (Android 5).
My Intention is to override the onMessageReceived() method of MyFirebaseMessagingService to catch the method sent by Firebase and create my own notification.
But it seems like onMessageReceived doesn't get called anyway. I followed the built-in instructions from Android Studio to implement firebase and testing with the firebase console does actually send a message received by my test devices.
So my question is, did I forgot to implement something? I have my custom FirebaseMessagingService, a BroadcastReceiver to implement actions in notifications and an Applicationclass that creates and handles the notification channels for SDKs >= 26.
This is a part of my manifest file:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.VIBRATE" />
<application
android:name=".Networking.Firebase.FireBaseApp"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".Activities.MainActivity"/>
<activity
android:name=".Activities.SplashActivity"
android:noHistory="true">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<service android:name=".Networking.Firebase.PushMessageService" />
<receiver android:name=".Networking.Firebase.PushReceiver"/>
</application>

class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(message: RemoteMessage?) {
super.onMessageReceived(message)
//TODO Your Code
}
}
}
<!-- Firebase Notifications Service -->
<service
android:name=".MyFirebaseMessagingService"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<!--
Set custom default icon. This is used when no icon is set for incoming notification messages.
-->
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="#drawable/ic_notification" />
<!--
Set color used with incoming notification messages. This is used when no color is set for the incoming
notification message.
-->
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="#color/colorAccent" />

You need two service extends
1. FirebaseMessagingService
2. FirebaseInstanceIdService
and in manifest
<service
android:name="yourClassExtendsFirebaseMessagingService"
android:enabled="true"
android:exported="true"
android:stopWithTask="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<!-- [END firebase_service] -->
<!-- [START firebase_iid_service] -->
<service android:name="yourClassExtendsFirebaseInstanceIdService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
FirebaseInstanceIdService needs to refresh token.
On Android O and above need to ask premisen run an app when it closes on some devices.

Android - Firebase Notification not opening targeted activity when app is in background but working properly in foreground

I have tried some solution from the stackoverflow . But not working properly in my case.
Below is my MyFirebaseMessagingService class which extends FirebaseMessagingService
public class MyFirebaseMessagingService extends FirebaseMessagingService {
String url , title , body ;
Map<String,String> data = new HashMap<>();
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
title = remoteMessage.getNotification().getTitle();
body = remoteMessage.getNotification().getBody();
if(remoteMessage.getData().size()>0){
Log.d("DATA", remoteMessage.getData().toString());
try{
data = remoteMessage.getData();
url = data.get("url");
}
catch (Exception e){
Log.e("Error", e.toString());
}
showNotification(url , title , body);
}
}
private void showNotification(String url, String title, String body) {
Intent intent = new Intent(this, NotificationViewer.class);
intent.putExtra("URL",url);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) ;
notificationBuilder.setContentTitle(title);
notificationBuilder.setContentText(body);
notificationBuilder.setAutoCancel(true);
notificationBuilder.setSmallIcon(R.drawable.logo);
notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0,notificationBuilder.build());
}
}
Below is my AndroidManifest.xml code .
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="dcastalia.com.munshijobsportal">

</application>
</manifest>
I have tried out some solution but not working in my case. Everything is working fine when app is foreground but not working in background. I want to open a particular activity name NotificationViewer.Java activity when user click on the notification. But when my app is in background it keep opening my Launcher Activity.

You need to set click action in your json payload in notification request
'click_action' => 'YourTAG' and apply same tag in your manifest activity
<activity
android:name=".activity.NotificationViewer">
<intent-filter>
<action android:name="YourTAG" />
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>

You are most likely using the Firebase Notification message instead of the Data message.
If this is the case, using Data FCM message should do the trick for you.
As can be seen in https://firebase.google.com/docs/cloud-messaging/concept-options
Use notification messages when you want FCM to handle displaying a notification on your client app's behalf. Use data messages when you want to process the messages on your client app.
Notification Messages:
When your application is in the foreground, it receives the payload, but when in the background, Notification messages are delivered to the notification tray.
Data Messages:
These are are always delivered to the application, regardless if it is in the foreground or in the background.
NOTE: The FCM data message alone will not bring your application in the foreground. You will need additional code that will do that upon reception of the data message.

Android starting an intent doesn't set the action

I'm working with push notifications. Receiving and displaying notifications is currently working, however the on-click event isn't acting as it should.
int NOTIFICATION_ID = 1593;
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.notification, title, System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;
Intent notificationIntent = new Intent(this, MyMainActivity.class);
notificationIntent.putExtra("test", "test");
notificationIntent.setAction("load_notifications");
PendingIntent intentNotification = PendingIntent.getActivity(this, 999, notificationIntent, 0);
notification.setLatestEventInfo(this, title, body, intentNotification);
notificationManager.notify(NOTIFICATION_ID, notification);
That's how I display my notification and it also includes starting/resuming my main activity.
However, the putExtra("test", "test") and the setAction seem to have no effect if I click on a notification while I'm in the app. If my app isn't working, launching it from the notification works fine.
My onResume function at my main activity:
public void onResume() {
super.onResume();
if(this.getIntent().getAction().equalsIgnoreCase("load_notifications")) {
//Do stuff
}
}
My app config is as following:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".Activity"
android:label="#string/app_name"
android:configChanges="orientation"
android:launchMode="singleInstance"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- Push notifications -->
<receiver android:name="com.google.android.gcm.GCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="com.app.android" />
</intent-filter>
</receiver>
<service android:name=".GCMIntentService" />
</application>

the answer maybe be here : Action buttons are not shown in notification
Notification Actions were introduced in API 16.
This means that you should be setting your target SDK to 16 or above.
However, only Jelly Bean and above can take advantage of the Notification Actions - make sure to test this feature on those platforms.
NotificationCompat.Builder takes care of generating a Notification compatible with whatever API it is running on, so keep using it if you are going to be supporting Ice Cream Sandwich and older. If not, simply using Notification.Builder will suffice (after changing the target SDK of course).
