I have an calendar app where the info is downloaded online and there is a recyclerView of events and I want to notify the user when there is a calendar event for today, and notify with the event name or names. I have done some googling but haven't been able to figure this out.
In my MainActivity.java this is the method I created as a test from a page online
private void addNotification() {
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setSmallIcon(R.drawable.ic_check);
mBuilder.setContentTitle("Notification Alert, Click Me!");
mBuilder.setContentText("Hi, This is Android Notification Detail!");
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(contentIntent);
// Add as notification
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(0, mBuilder.build());
}
But when I call this method nothing is happening, what am I doing wrong?
I think you are missing the channel of the notification
I have a different solution, try this one (I checked it on my phone)
calling the function:
showSmallNotification(R.drawable.ic_launcher_background, "title","message");
Function code
private void showSmallNotification( int icon, String title, String message){
String CHANNEL_ID = "Channel_01";
String CHANNEL_NAME = "Notification";
// I removed one of the semi-colons in the next line of code
NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
inboxStyle.addLine(message);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
// I would suggest that you use IMPORTANCE_DEFAULT instead of IMPORTANCE_HIGH
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
channel.enableVibration(true);
channel.setLightColor(Color.BLUE);
channel.enableLights(true);
//channel.canShowBadge();
// Did you mean to set the property to enable Show Badge?
channel.setShowBadge(true);
notificationManager.createNotificationChannel(channel);
}
Intent mainIntent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, mainIntent, 0);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(getApplicationContext(), CHANNEL_ID)
.setVibrate(new long[]{0, 100})
.setPriority(Notification.PRIORITY_MAX)
.setLights(Color.BLUE, 3000, 3000)
.setAutoCancel(true)
.setContentTitle(title)
.setContentIntent(pendingIntent)
.setSmallIcon(R.mipmap.ic_launcher)
.setStyle(inboxStyle)
.setContentText(message);
// Don't forget to set the ChannelID!!
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
notificationBuilder.setChannelId(CHANNEL_ID);
}
notificationManager.notify(CHANNEL_ID, 1, notificationBuilder.build());
}
Edit
In order to check if there are any events every day you will need to use AlarmManager as from it's name you can schedule an event every day
You can see a solution (or at least it will give a direction) once you did that I think the next step would be to send the intent to a service which will check if there are any events available in current day. If there are any just show the notification/s
alarm manager link

private void notificationDialog(String title,String info) {
String NOTIFICATION_CHANNEL_ID = "tutorialspoint_01";
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
builder.setSmallIcon(android.R.drawable.ic_dialog_alert);
Intent intent = new Intent(Cart.this, Order.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
builder.setContentIntent(pendingIntent);
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));
builder.setContentTitle(""+title);
builder.setContentText(""+info);
builder.setSubText("Tap to view the website.");
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Will display the notification in the notification bar
notificationManager.notify(1, builder.build());
}
I used this code for notification
Inside Order class I want to send something so that it will display time left like 20 min ,15 min left
It should also show notification after every 5 min
Can anyone help me
I have a group of notifications in Android App.
I need my application to know if the app was opened when the user clicked on the notification.
I have used a pending intent and it works brilliantly. But how can I check if the user has clicked on the notification group? It shows no links, no notifications sounds, nothing. I found no information in the documentation. Please help.
You can add flag in intent like isFromNotification boolean and then pass that intent to pending intent and then notify user.
Now in activity check intent has this parameter then the user has come from notification.
(simple like that)
Sample code
Intent notificationIntent = new Intent(this, TargetActivity.class);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_CLEAR_TASK
| Intent.FLAG_ACTIVITY_NEW_TASK);
String channel_Id = "app_channel_01";
notificationIntent.putExtra(AppConstants.INTENTDATA.ISFROMNOTIFICATION,
true);
PendingIntent pendingIntent = PendingIntent.getActivity(MyApplication.getInstance(),
0, notificationIntent,
0);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(MyApplication.getInstance(), channel_Id)
.setSmallIcon(R.mipmap.ic_launcher)
.setColor(MyApplication.getInstance().getResources().getColor(android.R.color.white))
.setContentTitle(getResources().getString(R.string.app_name))
.setContentText(message)
.setAutoCancel(true)
.setContentIntent(pendingIntent)
.setWhen(System.currentTimeMillis());
NotificationManager notificationManager =
(NotificationManager) MyApplication.getInstance().getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
// Create or update.
NotificationChannel channel = new NotificationChannel(channel_Id,
"General Notifications",
NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(notificationId, notificationBuilder.build());
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationManager notificationManager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
intent = new Intent(context, AlertDialog.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND); // added new line
intent.putExtra("STARTED_BY_RECEIVER", true);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 100, intent, PendingIntent.FLAG_UPDATE_CURRENT);
String CHANNEL_ID = "channel id";// The id of the channel.
CharSequence name = "Channel";
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, name, importance);
Notification notification = new Notification.Builder(context)
.setContentIntent(pendingIntent)
.setContentText("Some Text")
.setContentTitle("Notification")
.setAutoCancel(true)
.setOngoing(true)
.setSmallIcon(R.drawable.ic_notification_praying)
.setChannelId(CHANNEL_ID)
.build();
notificationManager.createNotificationChannel(mChannel);
notificationManager.notify(100 , notification);
} else {
NotificationManager notificationManager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
intent = new Intent(context, AlertDialog.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND); // added new line
intent.putExtra("STARTED_BY_RECEIVER", true);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 100, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_notification_praying)
.setContentIntent(pendingIntent)
.setContentText("Some Text")
.setContentTitle("Notification")
.setAutoCancel(true)
.setOngoing(true);
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
builder.setSound(alarmSound);
notificationManager.notify(100, builder.build());
}
}
I've made an application which show notification on time that user chose in main activity and Notification should disappear only when user tap on notification otherwise not..and it was working fine unless I've updated my phone to android Oreo (8.0) now notification show at time but auto disappear after sometime.. How to make notification not auto disappear (in android Oreo) but only when user tap on it?
alright I figure this out.. it was battery optimize option which was killing my application so that's why notification was disappearing.. I removed my application from auto optimize now it's working fine.
I just started working with notifications and now I'm trying to remove the notification and launch the app once the notification has been tapped in the notificationcenter.
I tried to work with the following code:
import android.app.NotificationManager;
public class ExpandNotification {
private int NOTIFICATION = 546;
private NotificationManager mNM;
public void onCreate() {
mNM.cancel(NOTIFICATION);
setContentView(R.layout.activity_on);
//Toast.makeText(this, "stopped service", Toast.LENGTH_SHORT).show();
}
I think this code executes the other class when tapped?
PendingIntent contentIntent = PendingIntent.getActivity(this, REQUEST_CODE, new Intent(this, ExpandNotification.class), 0);
However the notification doesn't go away, nor does the application launch.
But I'm able to swipe it to left or right to remove it but that's not what I want..
To get the same effect using Notification.Builder or NotificationCompat.Builder call setAutoCancel(true) on the Builder instance.
Use the flag Notification.FLAG_AUTO_CANCEL
Notification notification = new Notification(icon, tickerText, when);
notification.setLatestEventInfo(context, contentTitle, contentText, pendingIntent);
// Cancel the notification after its selected
notification.flags |= Notification.FLAG_AUTO_CANCEL;
and to launch the app:
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// Create a new intent which will be fired if you click on the notification
Intent intent = new Intent(context, App.class);
// Attach the intent to a pending intent
PendingIntent pendingIntent = PendingIntent.getActivity(context, intent_id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
This answer is too much late but specially i write following solution because notification constructor become deprecated so use notification using builder , like following :
**.setAutoCancel(true)** is used to remove notification on click
and entire notification is like follwoing :
private void makeNotification(String title,String msg){
Intent resultIntent = new Intent(this, MasterActivity.class);
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
this,
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setContentIntent(resultPendingIntent)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(title)
.setAutoCancel(true)
.setContentText(msg);
int mNotificationId = 001;
NotificationManager mNotifyMgr =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
mNotifyMgr.notify(mNotificationId, mBuilder.build());
}
Calling this method with title and message you get perfect notification.
You can directly add .setAutoCancel(true) this line into your code in order to remove notification on click.
This must be added in your builder variable.
Example:
mBuilder = new NotificationCompat.Builder(mContext);
mBuilder.setSmallIcon(R.mipmap.ic_launcher);
mBuilder.setContentTitle("Notification")
.setContentText("Hello")
.setSound(Settings.System.DEFAULT_NOTIFICATION_URI)
.setAutoCancel(true)
.setContentIntent(pendingIntent);
Best & simple way is set builder.setAutoCancel(true) it's cancel your notification after clicking on notification. I hope this code help you.
Builder for notification
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(android.R.drawable.btn_star);
builder.setContentTitle("This is title of notification");
builder.setContentText("This is a notification Text");
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));
For open an activity on clicking notification
Intent intent = new Intent(Broadcastdemo.this, ThreadDemo.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 113,intent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
Show bulder in notification
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(114, builder.build());
Complete code for show a notification with icon, image, title, description, auto cancel and on click open an activity
public void ShowIntentNotification(View v)
{
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(android.R.drawable.btn_star);
builder.setContentTitle("This is title of notification");
builder.setContentText("This is a notification Text");
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));

builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(114, builder.build());
}
For my it was that
.setPriority(Notification.PRIORITY_HIGH);
that was causing the notification to not clear after click... make sure you use:
.setPriority(Notification.PRIORITY_DEFAULT);
And .setAutoCancel(true) should work.
