I have a calendar library I grabbed off of github:
https://github.com/prolificinteractive/material-calendarview
And I'm having the user click on a date and add a reminder for that date, an alert dialog then pops up and asks them to enter the time they would like to be reminded on that day.
Now I was able to convert the text into a simpledate format and I spit it out into a string from a calendar object, so the date and time should be passing through the notification. But it doesn't seem to work anyways
Heres the code that sets the alarm:
Calendar cal = Calendar.getInstance();
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
notificationIntent.addCategory("android.intent.category.DEFAULT");
PendingIntent broadcast = PendingIntent.getService(context, 100, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
try {
cal.setTime(alertFormatter.parse(date));
System.out.print("Date added successfully");
} catch (ParseException e) {
System.out.println("Failed to add date");
}
cal.add(Calendar.HOUR, Integer.parseInt(hour.getText().toString()));
cal.add(Calendar.MINUTE, Integer.parseInt(minute.getText().toString()));
cal.add(Calendar.SECOND, 0);
if(spAMpm.getSelectedItem().equals("AM"))cal.add(Calendar.AM_PM, Calendar.AM);
else if (spAMpm.getSelectedItem().equals("PM"))cal.add(Calendar.AM_PM, Calendar.PM);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), broadcast);
Then the receiver I created to do what I need it to do:
public class UpcomingWorkNotification extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent notificationIntent = new Intent(context, UpcomingWork.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(UpcomingWork.class);
stackBuilder.addNextIntent(notificationIntent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Four.oh")
.setContentText("Assignment Due Soon!")
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, builder.build());
}
}
In the manifest I gave it this permission and added the receiver
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<receiver android:name=".UpcomingWorkNotification">
<action android:name="android.media.action.DISPLAY_NOTIFICATION" />
<category android:name="android.intent.category.DEFAULT" />
</receiver>
Even with all that the notification still doesn't appear when I set it
Can anyone help?
And thank you

I have added everything like adding a receiver in the manifest file, adding all permissions still I am not able to call notifications. I want to give a fixed times, Example Daily morning 8:00 am, 12:00 am,9:00 pm I want to show notifications, how to do that? please help me.
Manifest permissions
<uses-permission android:name="com.android.alarm.permission.SET_ALARM" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
Receiver
<receiver android:name=".Activity.Utils.AlertReceiver"> </receiver>
alert receiver class
public class AlertReceiver extends BroadcastReceiver {
NotificationManager notificationManager ;
boolean isNotificActive = false ;
int id =1;
#Override
public void onReceive(Context context, Intent intent) {
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Intent notificationIntent = new Intent(context, DashBoard.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

notificationManager.notify(100, mNotifyBuilder.build());
id++;
System.out.println("notification is calling ");
}
setting alarm from an adapter class
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, hour);
calendar.set(Calendar.MINUTE, min);
calendar.set(Calendar.SECOND, 10);
Intent intent1 = new Intent(context, DashBoard.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 100,intent1, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) context.getSystemService(context.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pendingIntent);
I want repeat my notification every day at 12h, but my code isn't working...
I launch my Alarm Manager in MainActivity in OnCreate like this :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ma);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 12);
calendar.set(Calendar.MINUTE, 00);
calendar.set(Calendar.SECOND, 0);
Intent intent1 = new Intent(MainActivity.this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0,intent1, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) MainActivity.this.getSystemService(MainActivity.this.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
And My AlarmReceiver Class :
public class AlarmReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Intent notificationIntent = new Intent(context, MainActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(
context).setSmallIcon(R.drawable.photo)
.setContentTitle("ça marche fdp")
.setContentText("Et ouai t'as bien réussi à afficher une notification bordel de cul").setSound(alarmSound)
.setAutoCancel(true).setWhen(when)
.setContentIntent(pendingIntent)
.setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
notificationManager.notify(0, mNotifyBuilder.build());
}
}
Do you know where is the problem ? Please don't dislike I just want learn code :(
Update your manifest file to have the following parameters for your receiver:
<receiver
android:name="com.example.alarmmanagernotifcation.AlarmReceiver"
android:enabled="true"
android:process=":remote" />
Then I believe the problem could be with the icon you have chosen with:
.setSmallIcon(R.drawable.photo)
If the image is not compatible then you will not see a crash outside the app, it will only show a fatal exception inside of the android monitor if the phone is plugged in, so it can go unnoticed and the notification will not be fired.
The drawable that is used needs to have the different sizes for different phone densities. To make the correct drawables, right click on your drawable package and do New -> Image Asset. From the pulldown select Notification Icons, and use that to generate all the different sizes for the icon.
I try to set an alarm depending user chocies while setting alarm i want to send that alarm's unique notification id to reciever.java. I want to get data by this id on reciever.java.
I have a form with this form users are adding their pills and I'm saving every pill in different xml files for example pill1.xml pill2.xml. That saved pills have alarm and notification when alarm time came for example pill2.xml i will show pill2 datas in notirifacation bar.
that code on bottom is how i create alarm.
Long alertTime = new GregorianCalendar().getTimeInMillis()+10*1000;
Intent alertIntent = new Intent(ilac_hatirlatma.this, hatirlatma_detay.class);
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, alertTime, PendingIntent.getBroadcast(ilac_hatirlatma.this, NOTIF_ID, alertIntent, PendingIntent.FLAG_UPDATE_CURRENT));
reciever.java
#Override
public void onReceive(Context context, Intent intent) {
createNotification(context, "İlaç Hatırlatma", "8 saatte bir içmeniz gereken 'Arvelez' adlı ilacınız bulunmaktadır.", "İlacınzı Almayı Unutmayınız!");
}
public void createNotification(Context context, String msg, String msgText, String msgAlert){
PendingIntent notificIntent = PendingIntent.getActivity(context, 0, new Intent(context, ilac_hatirlatma.class), 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context).setSmallIcon(R.drawable.app_icon).setContentTitle(msg).setTicker(msgAlert).setContentText(msgText);
mBuilder.setContentIntent(notificIntent);
mBuilder.setDefaults(NotificationCompat.DEFAULT_SOUND);
mBuilder.setAutoCancel(true);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());
}
Here i prepare the alarm manager, every day at same hour
alarmManager = (AlarmManager)getApplicationContext().getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(getApplicationContext(), MyBroadcastReceiver.class);
pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, intent, 0);
// Set the alarm to start at some time.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
int curHr = calendar.get(Calendar.HOUR_OF_DAY);
// Checking whether current hour is over 15
if (curHr >= 15)
{
// Since current hour is over 15, setting the date to the next day
calendar.add(Calendar.DATE, 1);
}
calendar.set(Calendar.HOUR_OF_DAY, 15);
calendar.set(Calendar.MINUTE, 30);
// every day
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, pendingIntent);
And here i have the BroadcastReceiver that generate the notification
public class MyBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent)
{
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
//Partial_wake_lock only need CPU active
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "tag");
//Acquire the lock
wl.acquire();
int mId = 0;
//Show the notification
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_action_edit)
.setContentTitle("YOUR APP NAME")
.setContentText("TAKE THE PILLS!")
.setAutoCancel(true)
.setDefaults(-1);
// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(context, MainActivity.class);
// The stack builder object will contain an artificial back stack for the
// started Activity.
// This ensures that navigating backward from the Activity leads out of
// your application to the Home screen.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(MainActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(mId, mBuilder.build());
//Release the lock
wl.release();
}
}
The permissions of the manifest
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.android.alarm.permission.SET_ALARM" />
And Receiver declaration in the manifest
<receiver android:name=".MyBroadcastReceiver" />
For setting your Alarm manager read documentation
If you need to pass data between AlarmManager and BroadcastReceiver use .putExtra() like how this post explain
Hope this helps!
i have an android with a date picker.
i would like to choose a date and save it with an action bar item.
at this moment, it should be set an notification with the selected date.
this is my first time with notifications.
can everybody tell me, how i realize this?
i use min. SDK 15
i try something like this, but with this the notification start directly:
intent = new Intent(this, Overview.class);
PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);
long[] pattern = {200,200,200,200,200,200,200,200,200};
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Notification n = new Notification.Builder(this)
.setContentTitle("My Titel")
.setContentText("This is the Body")
.setSmallIcon(R.drawable.ic_notification_appicon)
.setContentIntent(pIntent)
.setAutoCancel(true)
.setLights(Color.GREEN, 500, 500)
.setVibrate(pattern)
.setSound(alarmSound)
.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, n);
if you want to set a notification it should notify at n date you need to use a broadcast receiver and because a broadcast receiver up only for a short time its a better practice to use also intent service here you have a example how to do it.
this is the broadcast receiver class.
public class MyReceiver extends BroadcastReceiver {
public MyReceiver() {
}
#Override
public void onReceive(Context context, Intent intent) {
Intent intent1 = new Intent(context, MyNewIntentService.class);
context.startService(intent1);
}
}
and register it in the manifest.
<receiver
android:name=".MyReceiver"
android:enabled="true"
android:exported="false" >
</receiver>
this is the intent service class.
public class MyNewIntentService extends IntentService {
private static final int NOTIFICATION_ID = 3;
public MyNewIntentService() {
super("MyNewIntentService");
}
#Override
protected void onHandleIntent(Intent intent) {
Notification.Builder builder = new Notification.Builder(this);
builder.setContentTitle("My Titel");
builder.setContentText("This is the Body");
builder.setSmallIcon(R.drawable.ic_notification_appicon);
builder.setAutoCancel(true);
builder.setLights(Color.GREEN, 500, 500);
Intent notifyIntent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 2, notifyIntent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
Notification notificationCompat = builder.build();
NotificationManagerCompat managerCompat = NotificationManagerCompat.from(this);
managerCompat.notify(NOTIFICATION_ID, notificationCompat);
}
}
and register it in the manifest.
<service
android:name=".MyNewIntentService"
android:exported="false" >
</service>
and then in your activity set the alarm manger to start the broadcast receiver at a specific date like this this example use the date picker to help you with that:
DatePicker datePicker= (DatePicker)timeDialogView.findViewById(R.id.yourid);
and:
Calendar now = Calendar.getInstance();
Calendar current = Calendar.getInstance();
now.set(now.get( datePicker.getYear()), now.get(datePicker.getMonth()), now.get(datePicker.getDayOfMonth()), the hour, and the minute);
if(now.compareTo(current)<=0){
Toast.makeText(MainActivity.this,"invalid time",Toast.LENGTH_LONG).show();
}
else{
Intent notifyIntent = new Intent(context, MyReceiver.class);
notifyIntent.putExtra("title",item.getText());
PendingIntent pendingIntent = PendingIntent.getBroadcast
(context, NOTIFICATION_REMINDER, notifyIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC,now.getTimeInMillis(), pendingIntent);
}
i hope this will help you!
Is there a way to detect when a day was started or date or time changes (not changed by user, it is changed by system). Any BroadCastReciever to do it? I am using service to run it by every hour, But drains battery.
My requirement is to check when the day has started (when time changes to 12 AM) or time changes (hourly) I want to display the notification.
Create alarm set on a specified time say 00 hours in your case, using AlarmManager and BroadcastReceiver. And you will receive a brodcast on every new day.
private void setAlarm(Calendar targetCal){
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, targetCal.getTimeInMillis(), pendingIntent);
}
For further reference :
http://android-er.blogspot.in/2012/05/create-alarm-set-on-specified-time.html
or you can use ScheduledExecutorService to schedule and execute a task http://developer.android.com/reference/java/util/concurrent/ScheduledExecutorService.html
This is quite simple to do.
Step 1
Use the AlarmManager to fire up a BroadcastReceiver periodically..
private void showNotification() {
Intent alarmIntent = new Intent(this, NotificationReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 50000, pendingIntent);
}
Step 2
In the onReceive() do the checking when the time is 00 hours of the day, create a notification and show it.
public class NotificationReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Calendar now = GregorianCalendar.getInstance();
// This is where you check when you want to show the notification
if(now.get(Calendar.HOUR_OF_DAY) == 0){
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(context.getResources().getString(R.string.message_box_title))
.setContentText(context.getResources().getString(R.string.message_timesheet_not_up_to_date));
Intent resultIntent = new Intent(context, MainActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());
}
}
}
Step 3
Do forgot to register the custom BroadcastReceiver is Manifest
<receiver
android:name="com.example.NotificationReceiver"
android:process=":remote" />
