How to create notification after listview receives new data from an online JSON file?

I have an online JSON file that shows the latest country earthquakes, the listView adapter in my app receives data from this JSON file and the refresh is manually by user`s swipe, but now I am adding an automatic and timely basis refresh mode to my list, the questions is:
How can I create a system notification after a new quake is detected?

Write this below code for sending System notification in your app while your data is loaded from network request.
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Notification notification = new Notification.Builder(getApplicationContext())
.setContentTitle("App Name / Title Message")
.setContentText("Description Message hat data is updated")
.setDefaults(Notification.DEFAULT_ALL)
.setSmallIcon(R.drawable.ic_notification_icon)
.setColor(getResources().getColor(R.color.icon_color))
.setPriority(Notification.PRIORITY_HIGH) // will show notification even you are in app
.setContentIntent(pIntent)
.setAutoCancel(true)
.build();
notification.flags |= Notification.FLAG_ONLY_ALERT_ONCE | Notification.FLAG_SHOW_LIGHTS;
NotificationManager notificationManager = (NotificationManager)
getApplicationContext().getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(1, notification);
//you can use unique identification int number for notificationID instead of 1
putting this code block will show notification.

Just build a Notification like this
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle(textTitle)
.setContentText(textContent)
.setPriority(NotificationCompat.PRIORITY_DEFAULT);
And then just show it
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
// notificationId is a unique int for each notification that you must define
notificationManager.notify(notificationId, mBuilder.build());
And for anything other extras check the official documentation
In order for this to work you somehow should push when a new earthquake happens to your phone. If you have backend, you can send a push notification through the cloud messaging.
If you don't have backend just create a background service and pull data every now and then and when data says new earthquake jsut follow the notification creation from above.

ChatApp: Multiline Notifications

I am creating a Chat Application with Firebase. I send Notifications with Firebase Cloud Functions and recieve them on my phone. But for every message I get a new notification. And now I want to know if it is possible to create a Notification like in WhatsApp, with multible lines for each message in one Notification. My Code for a Notification:
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
String notification_tag = remoteMessage.getData().get("senderUiD");
Intent intent = new Intent(getApplicationContext(), Chat_Room.class);
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(getApplicationContext())
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(remoteMessage.getData().get("username"))
.setContentText(remoteMessage.getNotification().getBody())
.setVibrate(new long[]{1500, 0, 1500, 0})
.setLights(Color.BLUE, 2000, 1000)
.setWhen(remoteMessage.getSentTime())
.setAutoCancel(true)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setStyle(new NotificationCompat.BigTextStyle().bigText(remoteMessage.getNotification().getBody()))
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setContentIntent(pendingIntent);
notificationManager.notify(notification_tag, 0, notificationBuilder.build());
Thanks for your help ;)

When You Are Receiving Notification Message Your Notification In override last Notification
generate Rendam number
Random ran = new Random();
int notification_tag = r`an.nextInt(6) + 5;`
notificationManager.notify(notification_tag, 0, notificationBuilder.build());
also, fallow few step for grouping notification
NotificationCompat.Builder:contains the UI specification and action information
NotificationCompat.Builder.build() :used to create notification (Which returns Notification object)
Notification.InboxStyle: used to group the notifications belongs to same ID
NotificationManager.notify():to issue the notification.

Open particular activity/fragment after clicking on Firebase notification when app is closed

I know this question seems duplicate, but for my requirement, I have searched many posts online, but nothing worked for me.
My requirement
I'm using the Firebase to get the push notifications. When app was opened means everything working fine but my problem is, app is in background/closed if any push notification came means i want to open the particular activity or fragment when clicking on that notification, but it always opening the launcher/main activity.
For this, I have tried the following scenarios
Scenario 1
Used the bundle to transfer notification data from FirebaseMessagingService to the launcher/Main activity and based on the bundle data i'm redirecting to the particular activity/fragment
Scenario 2
By using Sharedpreference
Scenario 3
By using intent.putExtra
following the above scenarios everything working fine when app was opened but if my app was closed means it always redirecting to the main/launcher activity
My code
Intent intent = new Intent(this, MainActivity.class);
intent.putExtra("reqTo", messageBody);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(title)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
So, does anyone know how to open the particular activity/Fragment when clicking on the Firebase push notification when the app is closed.

public void showNotificationMessage(final String title, final String message, Intent intent) {
// Check for empty push message
if (TextUtils.isEmpty(message))
return;
// notification icon
final int icon = R.drawable.logo;
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
final PendingIntent resultPendingIntent =
PendingIntent.getActivity(
mContext,
0,
intent,
PendingIntent.FLAG_CANCEL_CURRENT
);
final NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
mContext);
final Uri alarmSound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE
+ "://" + mContext.getPackageName() + "/raw/notification");
showSmallNotification(mBuilder, icon, title, message, resultPendingIntent, alarmSound);
playNotificationSound();
}
private void showSmallNotification(NotificationCompat.Builder mBuilder, int icon, String title, String message, PendingIntent resultPendingIntent, Uri alarmSound) {
NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
inboxStyle.addLine(message);
Notification notification;
notification = mBuilder.setSmallIcon(icon).setTicker(title).setWhen(0)
.setAutoCancel(true)
.setContentTitle(title)
.setContentIntent(resultPendingIntent)
.setSound(alarmSound)
.setStyle(inboxStyle)
.setSmallIcon(R.drawable.logo)
.setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
.setContentText(message)
.build();
NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(Config.NOTIFICATION_ID, notification);
}
private void showBigNotification(Bitmap bitmap, NotificationCompat.Builder mBuilder, int icon, String title, String message, PendingIntent resultPendingIntent, Uri alarmSound) {
NotificationCompat.BigPictureStyle bigPictureStyle = new NotificationCompat.BigPictureStyle();
bigPictureStyle.setBigContentTitle(title);
bigPictureStyle.setSummaryText(Html.fromHtml(message).toString());
bigPictureStyle.bigPicture(bitmap);
Notification notification;
notification = mBuilder.setSmallIcon(icon).setTicker(title).setWhen(0)
.setAutoCancel(true)
.setContentTitle(title)
.setContentIntent(resultPendingIntent)
.setSound(alarmSound)
.setStyle(bigPictureStyle)
.setSmallIcon(R.drawable.logo)
.setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
.setContentText(message)
.build();
NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(Config.NOTIFICATION_ID_BIG_IMAGE, notification);
}
You can check app closed or not like this
if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {

This is very similar to my answer given here: https://stackoverflow.com/a/41441631/1291714
In summary though, you need to use Firebase Cloud Messaging and not Firebase Notifications in order to receive a message in the background and do custom processing. You need to send "data" messages to the client and then in your service, you will then always receive the callback, whether the app is in the foreground or background.
With Firebase Notifications, you will only receive the callback when the app is in the Foreground. When the app is in the background, the system will handle and display the notification for a user. You won't be able to customise this notification to open up a different intent.

android push notification not removed when i swipe

android push notification not removed when i swipe
following is my code that i trying to implement push notification
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(icon)
.setContentTitle(title)
.setAutoCancel(true)
.setContentText(message)
.setOngoing(true);
Intent notificationIntent = new Intent(context, MainActivity.class);
notificationIntent.putExtra("Your Message", message);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
notificationIntent.putExtra("type", type);
notificationIntent.putExtra("id", id);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(intent);
notificationManager.notify(NOTIFICATION_ID, mBuilder.build());
can somebody help me to resolve these issue

The .setOngoing(true); should be false, or just remove this line, if you don't put the .setOngoing(boolean) it will be false, so you'll be able to swipe the notification.
More information setOnGoing
Set whether this is an "ongoing" notification. Ongoing notifications cannot be dismissed by the user, so your application or service must take care of canceling them. They are typically used to indicate a background task that the user is actively engaged with (e.g., playing music) or is pending in some way and therefore occupying the device (e.g., a file download, sync operation, active network connection).
So your mBuilder should be like :
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(icon)
.setContentTitle(title)
.setAutoCancel(true)
.setContentText(message)
.setOngoing(false); //or just remove it

The setOngoing makes the notification not dismissible
.setOngoing(true);

Android - How to Display Large Text in Notification

I need to implement a code for displaying large text with 200 characters in Notifications. Here i used following code but it shows single line.
Intent notificationIntent;
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.icon)
.setContentTitle(context.getString(R.string.app_name))
.setContentText(message)
.setDefaults(Notification.DEFAULT_ALL)
.setAutoCancel(true);
notificationIntent = new Intent(context, Main.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pintent = PendingIntent.getActivity(context, 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(pintent);
NotificationManager mNotifyMgr =
(NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
// Builds the notification and issues it.
mNotifyMgr.notify(1, mBuilder.build());

You can choose from different styles to use for the notification builder:
In your case I would use the NotificationCompat.BigTextStyle. More details can be found here.
Don't forget to import v4 support when using this.

In my application, notification message is static but can't show all sentense.
I solved with subText properties of notification.
Notification n = new Notification.Builder(this)
.setContentTitle("Job Tracker Application")
.setContentText("GPS is turned off.")
.setSubText("Please turn on in the settings.")
.setSmallIcon(R.drawable.app_icon)
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.build();
Another notification sample have show under the blogs.
http://www.objc.io/issue-11/android-notifications.html
https://capdroid.wordpress.com/tag/android-notification/
http://www.tutorialspoint.com/android/android_notifications.htm

You add a style for the the large text.
Notification notification = new NotificationCompat.Builder(this, CHANNEL_SYNC)
.setContentTitle(title)
.setSmallIcon(R.drawable.ic_sync)
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))
.setColor(getResources().getColor(R.color.colorPrimaryLight))
.setContentIntent(pendingIntent)
.build();
