I am trying to implement multiple notifications for each reminder I have in my app. I found some leads around here that it could be achieved using unique id per each notification but it is not working I get only one notification which is overwritten by the last one set. Also I would like know how is it possible to keep the notification intact after device is rebooted please. Here is my code
//call notification activation Intent
Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
AlarmReceiver class
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
//creating unique id for each specific notification
int ID = (int) ((new Date().getTime()/1000L) % Integer.MAX_VALUE);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Intent notification = new Intent(context,MainActivity.class);
notification.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pi = PendingIntent.getActivity(context,0,notification,0);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder mynotification = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_date_range_black_48dp)
.setContentTitle("note taker")
.setContentText("you have a reminder about a note")
.setAutoCancel(true)
.setContentIntent(pi)
.setSound(defaultSoundUri)
.setVibrate(new long[]{1000,1000,1000,1000,1000});
notificationManager.notify(ID,mynotification.build());
}
}

I think the problem lies not in your notification, but in your AlarmManager.
Try using different ID for each PendingIntent, and set the flag to PendingIntent.FLAG_ONE_SHOT.
Your calling intent should look like this:
//call notification activation Intent
Intent intent = new Intent(getBaseContext(), AlarmReciever.class);
int RQS_1 = (int) System.currentTimeMillis();
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, PendingIntent.FLAG_ONE_SHOT);
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
Try to give different request code and PendingIntent.FLAG_UPDATE_CURRENT as Flag for Pending Intent and check like this,
PendingIntent pi = PendingIntent.getActivity(context, new Random().nextInt(1000000), notification, PendingIntent.FLAG_UPDATE_CURRENT);

I'm working on an app which will allow users to set multiple notifications, and cancel any notification they choose.
The problem I have is that when I cancel a pending intent using the AlarmManager it is cancelling all alarms. Each of my pending intents has it's own unique request code.
For instance I would call this to create the alarm and then delete:
setAlarm(5062, 1453269670) // Set alarm 1
setAlarm(5063, 1453774418) // Set alarm 2
cancelAlarm(5062) // Cancel alarm 1
cancelAlarm(5063) // Cancel alarm 2
Setting mutiple alarms always works, I can set as many as I like and they all produce the notification. However if I was to cancel alarm 1, it also cancels alarm 2.
I know that the pending intent has to be the same when setting and cancelling, and each pending intent has it's own unique request code, so I don't know why it's not working. I've spent many hours googling, but none of the suggested answers have helped me.
void setAlarm(int request_code, long alarm_time) {
Intent intent = new Intent(context, NotificationReceiver.class);
intent.putExtra("request_code", request_code);
PendingIntent pendingIntent = PendingIntent.getService(context, request_code, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, alarm_time, pendingIntent);
}
void cancelAlarm(int request_code) {
Intent intent = new Intent(context, NotificationReceiver.class);
intent.putExtra("request_code", request_code);
PendingIntent pendingIntent = PendingIntent.getService(context, request_code, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
pendingIntent.cancel();
alarmManager.cancel(pendingIntent);
}
The answer is simple
Intent firstIntent = new Intent(this, Receiver.class);
intent.setAction("action 1");
intent.putExtra("extra", "extra1");
firstPendingIntent = PendingIntent.getBroadcast(this, 0, firstIntent, 0);
Intent secondIntent = new Intent(this, Receiver.class);
intent.setAction("action 2");
intent.putExtra("extra", "extra2");
secondPendingIntent = PendingIntent.getBroadcast(this, 0, secondIntent, 0);
if you compare two PendingIntents created in ABOVE code they are NOT EQUAL
But in code BELOW:
Intent firstIntent = new Intent(this, Receiver.class);
intent.setAction("action 1");
intent.putExtra("extra", "extra1");
firstPendingIntent = PendingIntent.getBroadcast(this, 0, firstIntent, 0);
Intent secondIntent = new Intent(this, Receiver.class);
intent.setAction("action 1");
intent.putExtra("extra", "extra2");
secondPendingIntent = PendingIntent.getBroadcast(this, 0, secondIntent, 0);
if you compare two PendingIntents they gonna be EQUAL, so doesn't matter what you pass in putExtra method
I'm trying to schedule a method to be called using AlarmManager, but it doesn't seem to be working. I've looked at other examples and theirs isn't working for me. So I'm thinking it's something from my code. Here's the AlarmManager code:
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent intent = new Intent(SplashScreenActivity.this, KinectReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(SplashScreenActivity.this, 0, intent, 0);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 2);
calendar.set(Calendar.MINUTE, 25);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
And my broadcast receiver:
public class KinectReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Done", Toast.LENGTH_LONG).show();
Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_stat_notify)
.setContentTitle("Kinect")
.setColor(ContextCompat.getColor(context, R.color.colorAccent))
.setWhen(System.currentTimeMillis())
.setContentText("Your Kinects and Likes have been refilled. Now get to swiping")
.setAutoCancel(true)
.setSound(uri)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText("Your Kinects and Likes have been refilled. Now get to swiping"))
.setVibrate(new long[] { 100, 500, 100, 500, 100 });
Intent targetIntent = new Intent(context, MainActivity.class);
targetIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
targetIntent.putExtra("action", "main");
targetIntent.putExtra("id", "");
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);
builder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, builder.build());
}
}
Neither the Toast nor the Notification show.
The AlarmManager code is in the first thing that runs in my launcher activity, in case that helps. Thanks
Please register ur receiver in manifeast file like this
In application tag
<receiver
android:name=".KinectReceiver">
Second question is how to cancel alarm
Here is ur answer
Intent myIntent = new Intent(MainActivity.this, AlarmActivity.class);
pendingIntent = PendingIntent.getActivity(CellManageAddShowActivity.this,
id, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
pendingIntent.cancel();
alarmManager.cancel(pendingIntent);
The main thing that you will need is:
1).Create pending intent with the same id and appropriate intent FLAG.
2).Cancel that pending intent.
3).Cancel the alarm using alarm manager.
I will try to create multi local notification every time with different parameters this is my code to create the notification:
public void setNotficition(int Time,String ProdName,String ProdDesc,String ProdID){
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
notificationIntent.addCategory("android.intent.category.DEFAULT");
notificationIntent.putExtra("ProdName",ProdName);
notificationIntent.putExtra("ProdDesc",ProdDesc);
notificationIntent.putExtra("ProdID",ProdID);
PendingIntent broadcast = PendingIntent.getBroadcast(this, 100, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, Time);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),broadcast);
}
This is my Code for BroadcastReceiver:
#Override
public void onReceive(Context context, Intent intent) {
String ProdName= intent.getStringExtra("ProdName");
String ProdDesc= intent.getStringExtra("ProdDesc");
String ProdID= intent.getStringExtra("ProdID");
int ID = Integer.parseInt(ProdID);
Intent notificationIntent = new Intent(context, NotificationActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(NotificationActivity.class);
stackBuilder.addNextIntent(notificationIntent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
Notification notification = builder.setContentTitle(ProdName)
.setContentText(ProdDesc)
.setTicker("New Message Alert!")
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pendingIntent).build();
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify((int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE), notification);
}
Every time its take the last call
Notification id should be unique within your application.
If a notification with the same id has already been posted by your
application and has not yet been canceled, it will be replaced by the
updated information.
NotificationManager notiManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notiManager.notify(UNIQUE_ID, notification);
If you are using PendingIntent.getBroadcast() method, use different requestCode for different notification:
Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
notificationIntent.addCategory("android.intent.category.DEFAULT");
notificationIntent.putExtra("ProdName",ProdName);
notificationIntent.putExtra("ProdDesc",ProdDesc);
notificationIntent.putExtra("ProdID",ProdID);
PendingIntent broadcast = PendingIntent.getBroadcast(this, REQUEST_CODE, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Hope this will help!
You can create multiple notification by changing notification id, everytime.
PendingIntent broadcast = PendingIntent.getBroadcast(this, 100, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
The second parameter of the getBroadcast call is "notification id" (i.e. 100 in your case). Just use different different notification id in case of generating multiple Notifications.
Hope it will help u :-)
A notification is created and linked to a id, this id can be used to modify or update on existing notification, weather you are changing the intent or just the behavior of the stack.
I'm trying to set a notification to appear after a certain interval. I expected this to work however nothing seems to happen when running the code on my phone other than at reciever being printed to the console and I can't seem to find out why. Any help would be greatly appreciated.
Here is the code used to set the alarm.
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.SECOND, 10);
Intent intent = new Intent(getApplicationContext(), NotificationReciever.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 100, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_FIFTEEN_MINUTES, pendingIn
Here is the notification receiver class
public class NotificationReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
System.out.println("at reciever");
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Intent repeatingIntent = new Intent(context, LoginActivity.class);
repeatingIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 100, repeatingIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
.setContentIntent(pendingIntent)
.setContentTitle("Please Leave at the cage")
.setContentText("It almost 5")
.setAutoCancel(true);
notificationManager.notify(100, builder.build());
}
}
Here are the relevant manifest lines
receiver android:name=".NotificationReciever"
uses-permission android:name="com.android.alarm.permission.SET_ALARM"
Basically you need to set a icon for each notifications.
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
.setContentIntent(pendingIntent)
.setContentTitle("Please Leave at the cage")
.setSmallIcon(R.drawable.crosshair); //crosshair is the icon choice in this example
.setContentText("It almost 5")
.setAutoCancel(true);
I'm building a study planner application for Android, i have the AlarmManager set up and working to trigger a notification when the time elapses, which works fine.
When setting the alarm, the alarm details are saved into an SQLite database, when the alarm is set off, i need to recall the alarm information, is there some form of variable i can save into the database and link to the specific alarm so that i can use it in an SQLite query to find the correct entry.
UPDATE Code below:
Long nIdLong = System.currentTimeMillis();
String nId = nIdLong.toString();
Intent alarmIntent = new Intent(context, AlarmReceiver.class);
alarmIntent.putExtra("nID", nId);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent , 0);
AlarmManager alarmManager = (AlarmManager)getActivity().getSystemService(getActivity().ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
AlarmReciever:
public void onReceive(Context context, Intent intent)
{
long dbId = intent.getLongExtra("nID", 0);
String notificationId = Long.toString(dbId);
Log.i("App", "called receiver method");
try{
Toast.makeText(context, notificationId, Toast.LENGTH_LONG).show();
}catch(Exception e){
e.printStackTrace();
}
}
Thanks in advance
You're sending a String through the intent, it needs a Long, this code should work.
Long nIdLong = System.currentTimeMillis();
String nId = nIdLong.toString();
Intent alarmIntent = new Intent(context, AlarmReceiver.class);
alarmIntent.putExtra("nID", nIdLong);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent , 0);
AlarmManager alarmManager = (AlarmManager)getActivity().getSystemService(getActivity().ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
While setting the alarm, first retrieve the id which will be created while inserting alarm details to SQLite via
long uniqueId = db.insert(your query);
And put that in the intent for PendindIntent for AlarmManager
Intent alarmIntent = new Intent(this, AlarmEventReceiver.class);
alarmIntent.putExtra("dbId", uniqueId);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent , 0);
Inside the onReceive() of AlarmEventReceiver, you can get the id & retrieve the data from DB.
#Override
public void onReceive(Context context, Intent intent) {
long dbId = intent.getLongExtra("dbId", 0);
}
