I check it many times using Logs and prevent the notify() method of manager to be called multiple times if not necessary to avoid some overhead. Now I have first notification with a 0% progress then again I create a new notification with a 0% progress again, unfortunately only one notification is shown even their id is unique but later on when the first notification progress gets updated example from 0% to 25% then that's the only time it will show the desired output, a 2 notification with different progress value. I am using only one Notification, Notification Manager, and in Notification Builder since I do not want to create an overlap animation of notification when it gets updated. Is this expected behavior when in the foreground?

I am trying to use ListenableWorker to perform some background API calls.
During this process I want to display notification with a progress.
I use setForegroundAsync() function as per this documentation google docs
The problem is when my ListenableWorker stops, i can still see my ongong notification and i cant remove it.
This is my refresh fucntion where I change notification parameters:
private void updateRefreshStatus(float objectsProcessed, int totalObjects) {
if (totalObjects == 0) {
setProgressAsync(new Data.Builder().putFloat(PROGRESS_CONSTANT_ID, 100.0f).build());
setForegroundAsync(createForegroundInfo(FloatFormatter.roundFloatTwoDigitsAsString(100f)));
} else {
setProgressAsync(new Data.Builder().putFloat(PROGRESS_CONSTANT_ID, (objectsProcessed / (float) totalObjects) * 100f).build());
setForegroundAsync(createForegroundInfo(FloatFormatter.roundFloatTwoDigitsAsString((objectsProcessed / (float) totalObjects) * 100f)));
}
}
This is how I create my foregroundInfo:
private ForegroundInfo createForegroundInfo(#NonNull String progress) {
Notification notification = WorkerUtils.prepareProgressNotification("Update",
"Update progress " + progress + " %",
getApplicationContext());
return new ForegroundInfo(NOTIFICATION_PROGRESS_ID,notification);
}
This is my progress notification code:
static Notification prepareProgressNotification(String title, String message, Context context) {
// Make a channel if necessary
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
CharSequence name = WorkerConstants.VERBOSE_NOTIFICATION_CHANNEL_NAME;
String description = WorkerConstants.VERBOSE_NOTIFICATION_CHANNEL_DESCRIPTION;
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel channel =
new NotificationChannel(WorkerConstants.CHANNEL_ID, name, importance);
channel.setDescription(description);
// Add the channel
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
if (notificationManager != null) {
notificationManager.createNotificationChannel(channel);
}
}
// Create the notification
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, WorkerConstants.CHANNEL_ID)
.setContentTitle(title)
.setSmallIcon(R.drawable.ic_launcher)
.setContentText(message)
.setTicker(title)
.setOngoing(true)
.setAutoCancel(true)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setVibrate(new long[0]);
// Show the notification
return builder.build();
}
I tried calling cancelAll, cancel(id), but it does nothing in my case.
UPDATE: Removing .setOngoing(true) from builder, does nothing for me its seems like setForegroundAsync() issue?
This is my first question. I have connected my domain into firebase. The push notification is working when I update the post in my Wordpress Blog. Ok, thats good for now. But, i want to save all that notification in a Fragment, and can be clicked from there to start an activity for post id. How to save that Notification?
Here is my Firebase Messaging code:
private static int VIBRATION_TIME = 500; // in millisecond
private SharedPref sharedPref;
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
sharedPref = new SharedPref(this);
if (sharedPref.getNotification()) {
// play vibration
if (sharedPref.getVibration()) {
((Vibrator) getSystemService(Context.VIBRATOR_SERVICE)).vibrate(VIBRATION_TIME);
}
RingtoneManager.getRingtone(this, Uri.parse(sharedPref.getRingtone())).play();
if (remoteMessage.getData().size() > 0) {
Map<String, String> data = remoteMessage.getData();
FcmNotif fcmNotif = new FcmNotif();
fcmNotif.setTitle(data.get("title"));
fcmNotif.setContent(data.get("content"));
fcmNotif.setPost_id(Integer.parseInt(data.get("post_id")));
displayNotificationIntent(fcmNotif);
}
}
}
private void displayNotificationIntent(FcmNotif fcmNotif) {
Intent intent = new Intent(this, ActivitySplash.class);
if (fcmNotif.getPost_id() != -1) {
intent = new Intent(this, ActivityPostDetails.class);
Post post = new Post();
post.title = fcmNotif.getTitle();
post.id = fcmNotif.getPost_id();
boolean from_notif = !ActivityMain.active;
intent.putExtra(ActivityPostDetails.EXTRA_OBJC, post);
intent.putExtra(ActivityPostDetails.EXTRA_NOTIF, from_notif);
}
PendingIntent pendingIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentTitle(fcmNotif.getTitle());
builder.setStyle(new NotificationCompat.BigTextStyle().bigText(fcmNotif.getContent()));
builder.setContentText(fcmNotif.getContent());
builder.setSmallIcon(R.drawable.ic_notification);
builder.setDefaults(Notification.DEFAULT_LIGHTS);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
builder.setPriority(Notification.PRIORITY_HIGH);
}
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
int unique_id = (int) System.currentTimeMillis();
notificationManager.notify(unique_id, builder.build());
}
}
yes you can store the your Notification payload in database and create list in fragment and show data from Database and click on any row start activity according to Post ID by getting post id by position
You can save notification message when the notificaton arrived inside
onMessageReceived(RemoteMessage remoteMessage)
method like this
A full example of a notification is like this..
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";

I am developing an app that works with FirebaseMessagingService and NotificationCompat. My target API is 26. The problem I have is that notifications in android 7.1.1 appear and close at once, they are not kept in the notification bar. However, in Android 7.0 it works perfectly. I saw many tutorials and in all they do the same thing that I do. I would like to know what I may be missing.

Notification channels: Android 8.0 introduces notification channels that allow you to create a user-customizable channel for each type of notification you want to display.
Please have a look at the documentation.

mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
}
}
the problem is a NullPointerException here String user_id = userProfile.getId();. The userProfile cames from com.facebook.Profile class because I use facebook sdk to keep session. Why is it null?
here there is the stacktrace
java.lang.NullPointerException

If this code block is the first time you are calling FacebookSdk.sdkInitialize then the problem is likely that the user has not logged in yet, so there is no user profile, hence the NullPointerException. I had a similar problem a while back and this was the issue.
Make sure that you are calling the Login callback from the FacebookSDK. Hope this helps.
