I found this example of an alarm notification and I would just like to ask you to change two things.
This is MainActivity:
public void setRepeatingAlarm() {
Intent intent = new Intent(this, MyAlarmService.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,
intent, PendingIntent.FLAG_CANCEL_CURRENT);
am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),
(129600000), pendingIntent);
}
And this is MyAlarmService:
public class MyAlarmService extends BroadcastReceiver {
NotificationManager nm;
#Override
public void onReceive(Context context, Intent intent) {
nm = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence from = "Locali Torino";
CharSequence message = "Visita le serate!";
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
new Intent(), 0);
Notification notif = new Notification(R.drawable.disco,
"Visita le serate!", System.currentTimeMillis());
notif.setLatestEventInfo(context, from, message, contentIntent);
nm.notify(1, notif);
}
}
In this way, when I launch my app, now I see the notification but I would like to see it do so only after "x" milliseconds.
And then I want to know how to launch the MainActivity clicking on the notification.
Thank you.
Call setRepeatingAlarm() with some delay. From service or from activity use e.g. Handler and post a runnable to it with small delay. If you are in activity, dont't forget to remove post action within your lifecycle methods, e.g. onStop(). If you want to make some action when user click on notification, edit contentIntent in your MyAlarmService.
E.g.
Intent action = new Intent(context, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
action, 0);

Not sending notification at selected time, when I ran my code, directly showed notification
and showed error as well
Here is the error message: E/NotificationManager: notifyAsUser: tag=null, id=12345, user=UserHandle{0}
I thought the error message was due to Build.VERSION.SDK_INT, but after adding that, the error message is still there.
Place all of these under onCreate:
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 13);
calendar.set(Calendar.MINUTE,9)
;
Intent intent = new Intent ();
intent.setAction("com.example.Broadcast");
PendingIntent contentIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
// PendingIntent alarmIntent = PendingIntent.getBroadcast(this,0, intent,0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, contentIntent);
and here is the extend.
public class wakeReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
setNotification(context);
}
protected void setNotification(Context context){
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
new Intent(context, MainActivity.class), 0);
String ChannelId = "12345";
int uniID = 12345;
NotificationCompat.Builder builder = new NotificationCompat.Builder(context,ChannelId )
.setSmallIcon(R.mipmap.ic_launcher_round)
.setContentTitle("Hi")
.setAutoCancel(true)
.setWhen(System.currentTimeMillis())
.setContentText("Please Rate.");
builder.setContentIntent(contentIntent);
//
// Send notification to your device
NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
builder.setChannelId("com.myApp");
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(
"com.myApp",
"My App",
NotificationManager.IMPORTANCE_DEFAULT
);
if (manager != null) {
manager.createNotificationChannel(channel);
}
}
manager.notify(uniID, builder.build());
}
}
Can someone please help me with this?
You are very confused.
In your code you call NotificationManager.notify(). This will show the Notification immediately.
You do:
Intent intent = new Intent(this, MainActivity.class);
PendingIntent alarmIntent = PendingIntent.getBroadcast(this,0, intent,0);
This won't work. You have created a PendingIntent which will be sent via broadcast using an Intent that is for an Activity! What do you want to happen? Do you want an Activity to be launched or do you want a BroadcastReceiver to be triggered?
I think what you want to do is as follows:
Create an Intent for a BroadcastReceiver, wrap that in a PendingIntent using getBroadcast() and pass that to the AlarmManager so that the broadcast Intent will be set at some future time.
Create a class that extends BroadcastReceiver. In onReceive() create the Notification and call NotificationManager.notify() to post the Notification. In the Notification you can set a PendingIntent that opens your Activity so that if the user clicks on the Notification your Activity will be launched. To do this, call PendingIntent.getActivity() and pass an Intent that contains MainActivity.class.
I have an app, that have a MainActivity(Mr.Obvious), a Service and a BroadcastReceiver. In my MainActivity I have an AlarmManager like this:
Intent myIntent = new Intent(MainActivity.this, BroadReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, myIntent,0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
calendar.getTimeInMillis(),
AlarmManager.INTERVAL_HALF_DAY, pendingIntent);
In my BroadcastReceiver I have this:
public void onReceive(Context context, Intent intent) {
Intent service1 = new Intent(context, NotifyService.class);
context.startService(service1);
}
And in my service, I have this:
public int onStartCommand(Intent intent, int flags, int startId) {
NotificationManager notificationManager = (NotificationManager) this.getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
Intent intent1 = new Intent(this.getApplicationContext(),MainActivity.class);
Notification notification = new NotificationCompat.Builder(this)
.setTicker(getText(R.string.notification_ticker))
.setSmallIcon(R.drawable.green)
.setContentTitle(frase())
.setContentText(getText(R.string.notification_text))
.setAutoCancel(true)
.build();
intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP| Intent.FLAG_ACTIVITY_CLEAR_TOP);
notificationManager.notify(0, notification);}
I want my app to enable a button in MainActivity when the user receives a notification, it possible?
If your in background start activity newly
Intent in = new Intent(this, MainActivity.class);
in.putExtra("state", "background");
startActivity(in);
Get string extra then compare it and control the button
If your in foreground make button object as public then control it
Use a global variable to identify MainActivity in foreground or not(Using activity life cycle)
onDistroy()
onStart()
I have used broadcast receiver and alarm manager. Added the notification in particular date and time. The notification is showing fine. But when the user is touching the notification i want to launch myApplication.
Notification.Builder notification= new Notification.Builder(this);
notification.setContentTitle("MY Title");
notification.setContentText("Today you have scheduled for...");
notification.setSmallIcon(R.drawable.ic_app_launcher);
notification.setAutoCancel(true);
notification.build();
Intent notificationIntent = new Intent(this, NotificationPublisher.class);
notificationIntent.putExtra(NotificationPublisher.NOTIFICATION_ID, 1);
notificationIntent.putExtra(NotificationPublisher.NOTIFICATION, notification);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
long futureInMillis = dateSpecified.getTime(); //Some future date like 20 feb 2015
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, futureInMillis, pendingIntent);
NotificationPublisher class -BroadcastReciver
public class NotificationPublisher extends BroadcastReceiver {
public static String NOTIFICATION_ID = "notification-id";
public static String NOTIFICATION = "notification";
public void onReceive(Context context, Intent intent) {
NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = intent.getParcelableExtra(NOTIFICATION);
int id = intent.getIntExtra(NOTIFICATION_ID, 0);
notificationManager.notify(id, notification);
}
}
I referred this link.
I hope your understand what i'm trying to say.
Please anybody help me. Thanks lot.
But when the user is touching the notification i want to launch
myApplication.
Because NotificationPublisher BroadcastReceiver fire when notification is clicked so start Application from onReceive method of Receiver:
public void onReceive(Context context, Intent intent) {
// start application here
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = intent.getParcelableExtra(NOTIFICATION);
int id = intent.getIntExtra(NOTIFICATION_ID, 0);
Intent notificationIntent = new Intent(context, HomeActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intentn = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intentn);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(id, notification);
}
I am using alarm manager to display multiple local notification. The notification works fine, but the sequence of notification is happens only after i clear it from notification bar. The sequence is not happened.
code to pending intent
Intent intent = new Intent(this, TimeAlarm.class);
for(int i=0;i<milliSec.size();i++){
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,intent, PendingIntent.FLAG_ONE_SHOT);
am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),(milliSec.get(i)), pendingIntent);
System.out.println("Calling Alaram...");
Code to display notification
public void onReceive(Context context, Intent intent) {
nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence from = "Sample Notification";
CharSequence message = "Notification different milliseconds ...";
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, new Intent(), 0);
Notification notif = new Notification(R.drawable.ic_launcher, "Notification Test...", System.currentTimeMillis());
notif.setLatestEventInfo(context, from, message, contentIntent);
notif.flags= Notification.FLAG_AUTO_CANCEL;
nm.notify(1, notif);
}
How to do multiple notification sequence without clearing the existing message from notification. Thanks in advance
use this line of code
nm.notify( System.currentTimeMillis(), notif);
You have set it to 1 so every time it overrites notification
You always passing same requestcode in intent. so just need to change request code.
PendingIntent contentIntent = PendingIntent.getActivity(context, request_code, new Intent(), 0);
also need to change notify id.
nm.notify(change_notify_id, notif);
I am using AlarmManager and NotificationManager with BroadcastReceiver.
When I set an alarm with a specific date, it is working the first time. However, when I modify the date and click the confirm button, the alarm is working any date
immediately. I want to set the alarm interval day after expired date with fixed time.
What is the problem with it? I don't understand at the moment.
confirmButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
//set alarm with expiration date
am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
setOneTimeAlarm();
Toast.makeText(fridgeDetails.this, "Alarm automatic set",
Toast.LENGTH_SHORT).show();
setResult(RESULT_OK);
finish();
}
public void setOneTimeAlarm() {
c.set(Calendar.HOUR_OF_DAY, 14);
c.set(Calendar.MINUTE, 49);
c.set(expiredYear, expiredMonth, expiredDay);
Intent myIntent = new Intent(fridgeDetails.this, AlarmService.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
fridgeDetails.this, 0, myIntent, PendingIntent.FLAG_ONE_SHOT);
am.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, pendingIntent);
}
});
AlarmService.java
public class AlarmService extends BroadcastReceiver{
NotificationManager nm;
#Override
public void onReceive(Context context, Intent intent) {
nm = (NotificationManager) context.getSystemService(
Context.NOTIFICATION_SERVICE);
CharSequence from = "Check your fridge";
CharSequence message = "It's time to eat!";
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
new Intent(), 0);
Notification notif = new Notification(R.drawable.ic_launcher,
"Keep Fridge", System.currentTimeMillis());
notif.setLatestEventInfo(context, from, message, contentIntent);
notif.defaults |= Notification.DEFAULT_SOUND;
notif.flags |= Notification.FLAG_AUTO_CANCEL;
nm.notify(1, notif);
}
}
You need to set the property instead of FLAG_ONE_SHOT. This is for single alarm event not for the repeat. try this
PendingIntent pendingIntent = PendingIntent.getBroadcast(
fridgeDetails.this, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
see more detail about from here
Edit:
As you do for notification with PendingIntent
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,new Intent(), 0);
In this you pass the empty object of Intent you need to pass the class name for that when you click on notification which Activity will be launch like in Alarm set time you do
Intent myIntent = new Intent(fridgeDetails.this, AlarmService.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
fridgeDetails.this, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
now just pass the Acitivity name in the intent like suppose you want to launch your home activity and activity name like "homeactivity"
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,new Intent(context,HomeActivity.class), 0);
