Tapping android push notification sometimes does not redirect to the app

On tapping the push notifications user is usually redirected to the app, but some users do not get redirected to the app on tapping the push notifications.
For them the notification is simply dismissed and the app is not launched.
It might be a case, where these users have not opened the app for a long time, but would that affect the redirection to app behavior? I have also tried to reproduce this by forcing the device in doze mode, but I still get redirected to the app.
Can someone please help me solve this issue, where the user sometimes is not redirected to the app on tapping of the push notification.
This is my AndroidManifest.xml
<service
android:name=".screens.fcm.MyFirebaseMessagingService"
android:stopWithTask="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
and this is my FirebaseMessagingService
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Intent intent = new Intent(this, HomeActivity.class);
String notificationType = (remoteMessage.getData().get("notification_type") != null) ?
messageBody.getData().get("notification_type") : "";
if ((notificationType.equalsIgnoreCase("main")))
intent.putExtra("type", "main");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
RemoteMessage.Notification notification = remoteMessage.getNotification();
String notificationTitle = notification != null ? notification.getTitle() : "";
String notificationMessage = notification != null ? notification.getBody() : "";
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, "")
.setSmallIcon(R.drawable.notification)
.setContentTitle(notificationTitle)
.setContentText(notificationMessage)
.setAutoCancel(true)
.setGroup(GROUP_KEY_HOME_NOTIFICATIONS)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent)
.setPriority(NotificationCompat.PRIORITY_HIGH);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Since android Oreo notification channel is needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel("",
"Channel1",
NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

Unable to view my Push Notification in Oreo when app is in foreground/opened [duplicate]

I have integrated Firebase Cloud Messaging with my application.
When I sent a notification from the Firebase console, if the app is in background or not opened I receive successfully the notification,
otherwise if the app is in foreground or opened, I did not receive it.
All suggestions are appreciated.

When app is in foreground, notifications are not generated themselves. You need to write some additional code. When message is received onMessageReceived() method is called where you can generate the notification. Here is the code:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Log.d("msg", "onMessageReceived: " + remoteMessage.getData().get("message"));
Intent intent = new Intent(this, MainActivity.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.mipmap.ic_launcher)
.setContentTitle(remoteMessage.getNotification().getTitle())
.setContentText(remoteMessage.getNotification().getBody()).setAutoCancel(true).setContentIntent(pendingIntent);;
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId, "Default channel", NotificationManager.IMPORTANCE_DEFAULT);
manager.createNotificationChannel(channel);
}
manager.notify(0, builder.build());
}
}

FirebaseMessagingService never work when the app is in foreground. In this case if you want to receive the message from FCM then WakefulBroadcastReceiver will work for you
public class FirebaseDataReceiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("BroadcastReceiver::", "BroadcastReceiver");
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(intent.getExtras().getString("title"))
.setContentText(intent.getExtras().getString("message"));
NotificationManager manager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
manager.notify(0, builder.build());
}
}
Link firebase with GCM in play store and write the below code in manifest
<receiver
android:name=".firebase.FirebaseDataReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</receiver>

Stop receiveing notification FCM when apps is remove from Task Manager

I made apps that need to get a notification though the apps are closed. I'm using fcm to get the notification. But when the apps are removed from the recent task, I stop getting a notification. I had seen other article but I still can't get the answer to my problem.
I'm using firebase:
'com.google.firebase:firebase-messaging:11.0.2'
MyFirebaseMessagingService.java
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());
Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString());
Log.e(TAG," remote :" +remoteMessage.toString() );
try {
JSONObject json = new JSONObject(remoteMessage.getData());
String title = json.get("title").toString();
String message = json.get("message").toString();
createNottification(title, message);
}
catch (Exception ex){}
if(remoteMessage.getNotification() != null)
Log.d(TAG, "Message Notification Body: "+remoteMessage.getNotification().getBody());
}
private void createNottification(String title,String message)
{
Uri notificationSoundURI = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);;
Notification notification = new NotificationCompat.Builder(this)
.setContentTitle(title)
.setContentText(message)
.setSmallIcon(R.mipmap.pmi_launcher)
.setSound(notificationSoundURI )
.build();
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(getApplicationContext());
notificationManager.notify(Config.NOTIFICATION_ID, notification);
}
}
Manifest.xml
<!-- Firebase Notifications -->
<service android:name=".services.MyFirebaseMessagingService" android:stopWithTask="false">

first pass PendingIntent and also pass unique notification ID for generate bunch or stack of notification. also set Flags for notification Intent.so just do this in this way. Hope it helps to you and also other users.
private void sendNotification(String message,String title) {
int id = (int) System.currentTimeMillis();
Intent notificationIntent = new Intent(this, SplashActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
notificationIntent, 0);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setContentTitle(title)
.setContentText(message)
//.setStyle(new NotificationCompat.BigPictureStyle().bigPicture(image).setSummaryText(message))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
} else {
notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
}
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(id, notificationBuilder.build());
}

Firebase onMessageReceived(RemoteMessage remoteMessage), is not called when the app is in background [duplicate]

This question already has answers here:
Firebase onMessageReceived not called when app in background
(30 answers)
Closed 6 years ago.
In Firebase onMessageReceived(RemoteMessage remoteMessage), this method will be called when your app is in Foreground. So, on clicking the notification you can open a different Activity, say NotiicationActivity.
But what if your app is in background, then this method will not be called, and on clicking the notification only a Launcher Activity will be opened.
So how to open the NotificationActivity on clicking the notification even if our app is in background.
My Code is this :
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
}
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
sendNotification(remoteMessage.getNotification().getBody());
}
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, NewActivity.class);
intent.putExtra("key", messageBody);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Bitmap icon2 = BitmapFactory.decodeResource(getResources(),
R.mipmap.ic_launcher);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("FCM Sample")
.setContentText(messageBody)
.setAutoCancel(true)
.setLargeIcon(icon2)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(new Random().nextInt() /* ID of notification */, notificationBuilder.build());
}
}

onMessageReceived is only triggered when the application is in foreground.
If the app is backgrounded, you may still be able to receive the notification but onMessageReceived will not be triggered.
So my suggestion,
on the receiving activity, you can still get the data from the notification by using:
getIntent().getExtras();
This should work accordingly. Hope this helps :)

try and follow below link :
Firebase Cloud Messaging for Android

In your sendNotification() method :
private void showNotification(String message){
Intent intent=new Intent(this, NotificationActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("key", messageBody);
PendingIntent pendingIntent=PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder=new NotificationCompat.Builder(this)
.setAutoCancel(true)
.setContentTitle("FCM Sample")
.setContentText(message)
.setLargeIcon(icon2)
.setContentIntent(pendingIntent);
NotificationManager manager=(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(0,builder.build());
}

Why PendingIntent opens the launcher activity of the app rather than specific activity?

I am using firebase to send notification. It will open ResultActivity when user click on notification. It is working fine when app is in foreground. But when app is in background, it open the HomeActivity (which is the launcher activity of the app) rather than ResultActivity. I can't understand whats the problem?
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setContentTitle(getResources().getString(R.string.app_name));
notificationBuilder.setContentText(remoteMessage.getNotification().getBody());
notificationBuilder.setAutoCancel(true);
notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
Intent intent = new Intent(getApplicationContext(), ResultActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, PendingIntent.FLAG_ONE_SHOT);
notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}

This is an nice way to test click_action mapping. It requires an intent filter like the one specified in the FCM docs:
<intent-filter>
<action android:name="OPEN_ACTIVITY_1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
Also, remember, this will only work if the app is in the background. If it is in the foreground you will need to implement an extension of FirebaseMessagingService. In the onMessageReceived method,you will need to manually navigate to your click_action target
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
//This will give you the topic string from curl request (/topics/news)
Log.d(TAG, "From: " + remoteMessage.getFrom());
//This will give you the Text property in the curl request(Sample Message):
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
//This is where you get your click_action
Log.d(TAG, "Notification Click Action: " + remoteMessage.getNotification().getClickAction());
//put code here to navigate based on click_action
}
