Android: How to open app on silent push notification

I'm working on a patient-doctor call app using firebase notification.
When patient clicks on call button, the doctor should receive notification and the app should come in front whether the screen was off or app was in background.
Right now, when we send firebase notification, doctor has to click on the notification to open the app. The problem is, doctors don't look at the phone all the time and they say they did not get any notification.
I know app can be opened implicitly without user intervension as I'm using similar kind of another app.
I tried this code:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
if (remoteMessage.getData().size() > 0) {
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);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "channel_id")
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle(remoteMessage.getData().get("title"))
.setContentText(remoteMessage.getData().get("message"))
.setAutoCancel(true)
.setContentIntent(pendingIntent);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(0, builder.build());
}
}
}

android Notification - how to not show in foreground

hey all i got a tough problem and need advice. I have constructed a notification manually after recieving a FCM data payload. This is how the notification gets created both in foreground and background since its a data payload:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
String msg = remoteMessage.getData().get("message");
sendNotification(msg);
}
private PendingIntent createIntent(String msg) {
Intent intent = new Intent(this, SportsActivity.class);
Bundle b = new Bundle();
b.putString(Constants.KEY_GO_TO_TAB, Constants.KEY_DASHBOARD_HOCKEY_SCORE_TAB);
intent.putExtras(b);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
return pendingIntent;
}
private void sendNotification( String messageBody) {
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
android.support.v4.app.NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(messageBody))
.setContentText(messageBody)
.setColor(ContextCompat.getColor(this, R.color.hockey_brand))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(createIntent(messageBody));
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}
it seems to function fine. The issue im having is i want the notification to NOT SHOW in when the app is in the foreground. is there not a way to do this without scanning the activity task ? as this requires a permission
i've read this article but this how to know you've went from foreground to background. also android.permission.GET_TASKS is deprecated and REAL_GET_TASKS permission is not for third party either. I simply want to know at any given time that the user is either in foreground or background so i know if i should show a notification or not. I wonder if firebase itself has something. When you send a "Notification payload" from the firebase console if the app is not in the foreground is does not show in the notification panel so there should be a way to do this.

Alternatively you can choose not to show your notification when your app is in foreground by implementing Application.ActivityLifecycleCallbacks
in your Application.
Then you can check if your app is in foreground or background.

How to display notifications on Android application?

I need display notifications when my server return specific values. I have a service running on android and taskschedule running every time sending request to server, when the server return positive value i need display message on celular display, similar receive message of whatsapp (display icon and notification on display). Anyone have a sample?
I trying this:
PendingIntent resultPendingIntent = PendingIntent.getActivity(
this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
But my application is running as a service.

Please use Using Service to run background and create notification
private void processStartNotification() {
// Do something. For example, fetch fresh data from backend to create a rich notification?
final NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentTitle("Scheduled Notification")
.setAutoCancel(true)
.setColor(getResources().getColor(R.color.colorAccent))
.setContentText("This notification has been triggered by Notification Service")
.setSmallIcon(R.drawable.notification_icon);
PendingIntent pendingIntent = PendingIntent.getActivity(this,
NOTIFICATION_ID,
new Intent(this, NotificationActivity.class),
PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
builder.setDeleteIntent(NotificationEventReceiver.getDeleteIntent(this));
final NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(NOTIFICATION_ID, builder.build());
}

Android Insistent Notification Interrupted By SMS - How to make uninterruptable?

Short version:
I want to create a notification that is uninterruptible by all other notifications, SMS messages, etc until the user clears it.
Long version:
I'm using Firebase Cloud Messaging to send alerts to my phone. Messages are handled based on the topic, and I need to make the "alarm" messages repeat continuously until the notification is cleared by the user. This is currently accomplished by setting the notification with FLAG_INSISTENT, which loops the sound.
The problem is the insistent "alarm" notification is permanently stopped when a different notification or SMS comes through.
I would like to ignore all new notifications, or restart the alarm after the new notification plays. I've searched for a couple hours and tried several flags and settings, but can't figure out how to do it.
Here is the code I'm using to handle FCM messages and set the notifications:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
if (remoteMessage.getData() != null){
String messageTopic= remoteMessage.getFrom();
String messageTitle = remoteMessage.getData().get("title");
String messageBody = remoteMessage.getData().get("message");
if (messageTopic.equals("/topics/news")) {
Intent intent = new Intent(this, MainScreenActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri soundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_stat_news)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(soundUri)
.setContentIntent(pendingIntent)
.setPriority(Notification.PRIORITY_MAX);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(30548, notificationBuilder.build());
}
else if (messageTopic.equals("/topics/alarm")) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("http://www.example.com/alarm.php"));
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_stat_alarm)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(soundUri)
.setContentIntent(pendingIntent)
.setPriority(Notification.PRIORITY_MAX);
Notification mNotification = notificationBuilder.build();
mNotification.flags |= Notification.FLAG_INSISTENT;
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(30549, mNotification);
}
}
}
I may be able to prevent my own notifications from interrupting the alarm by ignoring them when the alarm notification ID (30549) is active (or create the new notification and then create the alarm again). However, SMS and notifications from other programs will still interrupt, so that wouldn't be a perfect solution.

I don't think you'll have luck with this, unfortunately. Android will not let you have a notification that takes full priority from my understanding.
However, in the Firebase console when you go to the notifications section and click advanced you can set the priority of a notification to High and set a sound.
Since it looks like you're writing the notification programmatically and setting priority to Max this will achieve the same affect.
Setting priority to high, from Google's documentation:
When a high-priority notification arrives (see right), it is presented to users for a short period of time with an expanded layout exposing possible actions.
After this period of time, the notification retreats to the notification shade. If a notification's priority is flagged as High, Max, or full-screen, it gets a heads-up notification

How to make a notification started using startForeground(), sync its notification with wearable?

I found that notifications triggered while using startForeground() is not showing up in wearables,
ie. for below code,
Intent notIntent = new Intent(this, MainActivity.class);
notIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendInt = PendingIntent.getActivity(this, 0,
notIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentIntent(pendInt)
.setSmallIcon(R.drawable.play)
.setTicker(songTitle)
.setContentTitle("Playing")
.setContentText(songTitle);
Notification not = builder.build();
startForeground(NOTIFY_ID, not);
but if I re-write the code like this,
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentIntent(pendInt)
.setSmallIcon(R.drawable.play)
.setTicker(songTitle)
.setContentTitle("Playing")
.setContentText(songTitle);
NotificationManagerCompat notificationManager =
NotificationManagerCompat.from(MusicService.this);
notificationManager.notify(NOTIFY_ID, builder.build());
wearbles start displaying it.
So my conclusion is that startForeground() might not be using the 'Compat' version of notification manager to notify.Is there any way I can foreground a service and make the notification it produce to also show up on a wearable without writing a wearable app?
P.S I am talking about a handheld app here not a wear app, the topic of discussion is syncing the notification from a handheld app which is started using startforeground() in a service of the handheld app to auto sync with a wearable.
