I am almost done, but when clicking the set Alarm button to fire the notification after 5 seconds for example, nothing happens.
this is the OnClick method for SetAlarm
public void setAlarm(View view) {
long alertTime = new GregorianCalendar().getTimeInMillis()+5*1000;
Intent alertIntent = new Intent(this, AlertReceiver.class);
//schedule to happen at later date
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, alertTime, PendingIntent.getBroadcast(this, 1, alertIntent, PendingIntent.FLAG_UPDATE_CURRENT));
}
and this is my receiver:
public class AlertReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
createNotification(context, "Times up", "5 seconds has passed", "Alert");
}
public void createNotification(Context context, String msg, String msgText, String msgAlert) {
PendingIntent notificIntent = PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), 0);
NotificationCompat.Builder mBuilder=new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.not)
.setContentTitle(msg)
.setTicker(msgAlert)
.setContentText(msgText);
//intent to fire when notification clicked on
mBuilder.setContentIntent(notificIntent);
//how the person will be notified
mBuilder.setDefaults(NotificationCompat.DEFAULT_SOUND);
//cancel notification when clicked in the taskbar
mBuilder.setAutoCancel(true);
NotificationManager mNotificationManager= (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1,mBuilder.build());
}
and this is my Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.yahyazeid.testnotification" >

Any suggestions?

Try this code. It looks like you did not set the notification in your receiver.
public void scheduleAlarm(View V)
{
// time at which alarm will be scheduled here alarm is scheduled at 1 day from current time,
// we fetch the current time in milliseconds and added 1 day time
// i.e. 24*60*60*1000= 86,400,000 milliseconds in a day
Long time = new GregorianCalendar().getTimeInMillis()+5*1000;
// create an Intent and set the class which will execute when Alarm triggers, here we have
// given AlarmReciever in the Intent, the onRecieve() method of this class will execute when
Intent intentAlarm = new Intent(this, AlarmReciever.class);
//Get the Alarm Service
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
//set the alarm for particular time
alarmManager.set(AlarmManager.RTC_WAKEUP,time, PendingIntent.getBroadcast(this,1, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
Toast.makeText(this, "Alarm Set for 5 seconds", Toast.LENGTH_LONG).show();
Then for the Receiver
public class Receiver extends Service {
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.depressiontest)
.setContentTitle("Time has Expired")
.setContentText("5 Seconds has passed.")
.setVibrate(pattern)
.setAutoCancel(true);
mBuilder.setContentIntent(pi);
mBuilder.setDefaults(Notification.DEFAULT_SOUND);
mBuilder.setAutoCancel(true);
NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, mBuilder.build());
}
And then in your manifest
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<service android:name=".Receiver">
<intent-filter> <action android:name="NOTIFICATION_SERVICE" />
</intent- filter>
</service>
For setting a specific date using the get Calendar instance
Calendar cal = Calendar.getInstance();
//Setting date for 11/29/2016
cal.set(Calendar.DATE,29); //1-31 days of week
cal.set(Calendar.MONTH,10); //January starts at 0 (zero), December = 11
cal.set(Calendar.YEAR,2016);//year...
//Setting the specific hour/min/sec
cal.set(Calendar.HOUR_OF_DAY, 16); //HOUR
cal.set(Calendar.MINUTE, 39); //MIN
cal.set(Calendar.SECOND, 10); //SEC
// Create a new PendingIntent and add it to the AlarmManager
Intent intent = new Intent(MainActivity.this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getService(MainActivity.this, 0,intent, 0);
//or if you start an Activity
//PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0,intent, 0);
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

I'm relatively new to Android so I'm quite puzzled here...
I want a notification to be triggered at a certain time on a daily basis.
I use a Calendar class to set the time when the notification is triggered every day, and AlarmManager to set the repeating task.
The problem is, the notification is triggered when the app is initially launched and not at the pre-defined time configured in the Calendar object. When I run in debug mode, I see that I go to the setExact method.
I also created a receiver to handle the notification itself and open the MainActivity when the notification is clicked.
MainActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
.
.
.
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 8);
calendar.set(Calendar.MINUTE, 30);
calendar.set(Calendar.SECOND, 0);
Intent intent = new Intent(this, NotificationReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 100, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
if (Build.VERSION.SDK_INT < 19)
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
else
alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}
NotificationReceiver.java
public class NotificationReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
NotificationManager manager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Intent mainIntent = new Intent(context, MainActivity.class);
mainIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 100, mainIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Notification.Builder builder = new Notification.Builder(context);
builder.setContentTitle("This is the title")
.setContentText("This is the text")
.setContentIntent(pendingIntent)
.setSmallIcon(R.drawable.deal_icon);
Notification notification = builder.build();
notification.defaults = Notification.DEFAULT_VIBRATE | Notification.DEFAULT_SOUND;
notification.flags |= Notification.FLAG_AUTO_CANCEL;
manager.notify(100, notification);
}
}

Calendar.getInstance() returns a calendar at your current local time. You're then setting the time to be what you wish, with today's date. When you schedule an alarm, the date is likely in the past. The system then will trigger the alarm immediately.
I believe you should use setRepeating(). You can set the trigger / interval times. Keep in mind that your app, or even the device itself, isn't necessarily running all the time.
I need to start alarm at every 30 seconds, I need it to be activated without running the app. But whether the app runs or not the AlarmReceiver do not get called. Any suggestions?
start method is in MainActivity.java class
public void start() {
Calendar calendar=Calendar.getInstance();
calendar.add(Calendar.SECOND, 30);
Intent intent = new Intent(MainActivity.this, AlarmReceiver.class);
PendingIntent pintent = PendingIntent.getService(MainActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarm.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pintent);
Log.d("alarm","alarm set for alarm receiver");
}
My Receiver file
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// Toast.makeText(context,"Alarm Receiver ",Toast.LENGTH_SHORT).show();
Log.d("Alarm","Alarm receive");
}
}

here i am able to set alarm, but i didn't receive alarm
In this page there is a finished example of what you need:
https://www.thepolyglotdeveloper.com/2014/10/use-broadcast-receiver-background-services-android/
Apparently you have to change the line:
PendingIntent pintent = PendingIntent.getService(MainActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
To
PendingIntent pintent = PendingIntent.getBroadcast(MainActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Change your start method to this:
public void start() {
Intent alarmIntent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, 0);
AlarmManager manager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
int interval = 30 * 1000; // 30 seconds of interval.
manager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), interval, pendingIntent);
Toast.makeText(this, "Alarm Set", Toast.LENGTH_SHORT).show();
}
Let me know if works.
I ran into this issue recently. The problem was with my custom Parcelable object, using primitives instead worked fine. This answer helped me: Sending Extras to onReceive only retrieves ALARM_COUNT
I'm trying to make my application use AlarmManager to send a notification after 5 seconds, but the pendingIntent doesn't seem to get called.
Heres my code
In onCreate in MainActivity:
Long alertTime = new GregorianCalendar().getTimeInMillis()+5*1000;
Intent alertIntent = new Intent(this, Notification.class);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, alertTime , PendingIntent.getBroadcast(this, 1, alertIntent, PendingIntent.FLAG_UPDATE_CURRENT));
Notification.class:
public class Notification extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
PendingIntent notificIntent = PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
mBuilder.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Title")
.setTicker("Ticker")
.setContentText("Text");
mBuilder.setContentIntent(notificIntent);
mBuilder.setDefaults(NotificationCompat.DEFAULT_VIBRATE);
mBuilder.setAutoCancel(true);
NotificationManager mNotificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());
}
}

i have searched for hours but i can't find out why nothing is happening
See: https://developer.android.com/reference/android/app/AlarmManager.html#set(int, long, android.app.PendingIntent)
Note: Beginning in API 19, the trigger time passed to this method is
treated as inexact: the alarm will not be delivered before this time,
but may be deferred and delivered some time later. The OS will use
this policy in order to "batch" alarms together across the entire
system, minimizing the number of times the device needs to "wake up"
and minimizing battery use. In general, alarms scheduled in the near
future will not be deferred as long as alarms scheduled far in the
future.
only 5 seconds?
try this:
new Handler().postDelayed(new Runnable() {
public void run() {
showNotification(); //your notification code called after 5 seconds
}
}, 5 * 1000); // 5 seconds...
OR TRY:
long alertTime = System.currentTimeMillis() + (5 * 1000); // <-- try this
Intent alertIntent = new Intent(this, Notification.class);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, alertTime , PendingIntent.getBroadcast(this, 1, alertIntent, PendingIntent.FLAG_UPDATE_CURRENT));
Here is my code below, what is the problem? If i look at log, there is no start of AlarmReceiver class. So no notification is sent to user. I tried every minute in loop and still nothing happened. What am i doing wrong?
Thanks in Advance!!
public void setRepeatingAlarm(int hour, int min)
{
Intent myIntent = new Intent(this , AlarmReceiver.class);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

Change PendingIntent.getService to PendingIntent.getBroadcast:
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, myIntent, 0);
Because PendingIntent.getService is used to Retrieve a PendingIntent that will start a service,... but PendingIntent.getBroadcast for Retrieve a PendingIntent that will perform a broadcast,...
So i have a problem with my notification. it doesn't tiger. So if somebody could help me with this.
here is the MainActivity:
Intent myIntent = new Intent(this , NotifyService.class);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.HOUR, 0);
calendar.set(Calendar.AM_PM, Calendar.AM);
calendar.add(Calendar.DAY_OF_MONTH, 1);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000*60*60*24 , pendingIntent);
The Service class
public class NotifyService extends Service {
#Override
public void onCreate() {
NotificationCompat.Builder builder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Notifications Example")
.setContentText("This is a test notification");
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(contentIntent);
// Add as notification
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(FM_NOTIFICATION_ID, builder.build());

So i set the AlarmManager to trigger at midnight. i set the time on my phone but nothing happens.
Your NotifyService is not declared in manifest file.
declare it like
<service android:name=".NotifyService">
</service>
