I have an alarm set up to deliver an intent with a notification to a broadcast receiver which then fires the notification. Pre 7.0, the notification is present in the intent when received, on 7.0 it's missing.
Here's the code which generates the notification.
public static void scheduleNotification(Context context, String message, long delay,
MainDisplay.NotificationType type) {
Notification.Builder builder = new Notification.Builder(context).setSmallIcon(
R.drawable.ic_stat_o)
.setContentTitle(
"Title")
.setContentText(
message)
.setStyle(
new Notification
.BigTextStyle()
.bigText(
message));
final Intent notificationIntent = generateNotificationIntent(context);
notificationIntent.putExtra(NotificationPublisher.NOTIFICATION, builder.build());
notificationIntent.putExtra(TYPE_KEY, type);
final PendingIntent pendingIntent = generatePendingIntent(context, notificationIntent);
final long futureInMillis = SystemClock.elapsedRealtime() + delay;
final AlarmManager alarmManager = (AlarmManager) context.getSystemService(
Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, futureInMillis, pendingIntent);
}
Here's the pending intent code.
public static PendingIntent generatePendingIntent(Context context, Intent notificationIntent) {
return PendingIntent.getBroadcast(context, 0, notificationIntent,
PendingIntent
.FLAG_UPDATE_CURRENT);
}
Here's the code that receives it.
public void onReceive(final Context context, Intent intent) {
final NotificationManager
notificationManager = (NotificationManager) context.getSystemService(
Context.NOTIFICATION_SERVICE);
final Notification notification = intent.getParcelableExtra(NOTIFICATION);
final int id = intent.getIntExtra(NOTIFICATION_ID, 0);
notificationManager.notify(id, notification);
Any ideas? Thanks!
I noticed that a serialized enum that I sent along was missing as well, I know there were changes in 7.0 with regards to intent transactions that were too large, but I'm not sure how that would apply here as no exceptions were thrown. I opted to simply send along the required info to construct the notification in onReceive.

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.
When users click the icon of my app on the Notification bar, users will be redirected to my app.
Can anyone provide sample code? How to subscribe to the click event, and the redirection.
Update
My application might be using some services that cause the display of icon on Notification bar.
My application is calling SetForeground, not getBroadcast().
Update 2
how can I redirect users to the last Activity rather than the hard-code activity? For example, the last Activity might be different when users navigate to different activity.
Notification click event in xamarin forms
It's a sample from my app, it works. I think you can do somthing similar.
public class AlarmReceiver extends BroadcastReceiver {
public final static String NOTIF_TEXT = AlarmSetActivity.class.getPackage() + ".NOTIF_TEXT";
private String notifText;
#Override
public void onReceive(Context context, Intent intent) {
notifText = intent.getExtras().getString(NOTIF_TEXT);
//().getExtras().getString(NOTE_BODY);
Toast.makeText(context, "Notification from " + R.string.app_name,
Toast.LENGTH_LONG).show();
buildNotification(context);
}
private void buildNotification(Context context) {
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
String channelId = "default_channel_id";
String channelDescription = "Default Channel";
Notification.Builder builder = new Notification.Builder(context);
Intent intent = new Intent(context, **EditorActivity.class**);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
intent, 0);
builder.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(context.getString(R.string.notificTitle)).setContentText(notifText)
.setContentInfo(context.getString(R.string.notificInfo)).setTicker(context.getString(R.string.notifTicker))
.setLights(0xFFFF0000, 500, 500)
//.setChannelId(id)
.setContentIntent(pendingIntent).setAutoCancel(true);
Notification notification = builder.build();
//notification.so
notificationManager.notify(2, notification);
}
}
And:
private void setAlarm(Calendar targetCal) {
mTimeTextView.setText(R.string.alarm_on);
mTimeTextView.append(String.valueOf(targetCal.getTime()));
Intent intent = new Intent(getApplicationContext(), AlarmReceiver.class);
intent.putExtra(AlarmReceiver.NOTIF_TEXT,notificationText);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
getApplicationContext(), RQS_TIME, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),
pendingIntent);
}
I am trying to push notification at the certain time. To perform this I am triggering the alarm which eventually call the broadcast receiver that show the notifications.
private void setAlarmToCallNotificationService(Context context, int request_code, String notificationText, String notificationTitle) {
Log.i("Inside notification,","Yes");
Intent intent = new Intent(context, notificationService.class);
intent.putExtra("Notification_title",notificationTitle);
intent.putExtra("Notification_text",notificationText);
//hit the notification At the 8.00 in the morning
Calendar notificationCalendar=Calendar.getInstance();
notificationCalendar.set(Calendar.HOUR_OF_DAY,16);
notificationCalendar.set(Calendar.MINUTE,29);
notificationCalendar.set(Calendar.SECOND,0);
Long time=notificationCalendar.getTimeInMillis();
System.out.println("NOTIFICATION Time is "+notificationCalendar.get(Calendar.HOUR_OF_DAY)+" "+notificationCalendar.get(Calendar.MINUTE));
Log.i("Target",time.toString());
//final int _id = (int) System.currentTimeMillis();
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, request_code, intent, PendingIntent.FLAG_ONE_SHOT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, time, pendingIntent);
}
I checked that the alarm is firing up.
public class notificationService extends BroadcastReceiver {
public static String TAG="notificationService";
#Override
public void onReceive(Context context, Intent intent) {
String notificatioTitle=intent.getExtras().getString("Notification_title");
String notificationMsg=intent.getExtras().getString("Notification_text");
Log.i(TAG,"Notification title "+notificatioTitle);
Log.i(TAG,"Notification msg "+notificationMsg);
NotificationCompat.Builder notification=new NotificationCompat.Builder(context)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(notificatioTitle)
.setContentText(notificationMsg);
NotificationManager mNotificationManager =(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0,notification.build());
}
}
Manifest file:
<receiver android:name=".notificationService" />
Did your receiver receive intent at expected time?
I mean... did the code below print anything at all?
Log.i(TAG,"Notification title "+notificatioTitle);
Log.i(TAG,"Notification msg "+notificationMsg);
If no, check if you use Settings.System.AUTO_TIME in you device DateTimeSettings,
You may need to use NTP time to set alarm.
long currentTime = System.currentTimeMillis() - ntpTimeOffset;
long timeToWaitForTrigger = calendar.getTimeInMillis() - currentTime;
alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + timeToWaitForTrigger, pendingIntent);
I am new to android and currently learning about notifications, there's a small app I am making which is supposed to show notification later in time and should open an activity when user taps on them. I have been looking for content all over internet but can't really understand how to do both task. I am using a broadcast receiver and here's my code
Notification.Builder builder = new Notification.Builder(getActivity());
builder.setContentTitle("Remember to return");
builder.setContentText(title);
builder.setSmallIcon(R.drawable.ic_notification);
builder.setAutoCancel(true);
//NotificationCompat.Builder builder = new NotificationCompat.Builder(getActivity());
Notification notification = builder.build();
Intent notificationIntent = new Intent(getActivity(),NotificationPublisher.class);
notificationIntent.putExtra(NotificationPublisher.NOTIFICATION_ID,1);
notificationIntent.putExtra(NotificationPublisher.NOTIFICATION,notification);
PendingIntent pendingIntent = PendingIntent.getBroadcast(activity,0,notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//long _notificationTimeInMillis = SystemClock.elapsedRealtime()+date.getTime()+getMillisFromHours(6);
long notificationTimeInMillis = SystemClock.elapsedRealtime() + 5000;
AlarmManager alarmManager = (AlarmManager)activity.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP,notificationTimeInMillis,pendingIntent);
Toast.makeText(activity,"Notification Set",Toast.LENGTH_SHORT);
and for reciever
public class NotificationPublisher extends BroadcastReceiver {
public static String NOTIFICATION_ID = "notification-id";
public static String NOTIFICATION = "notification";
#Override
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);
}
}
Currently I am able to show notifications, what changes to I have to make so that an activity (say HomeActivity.class) opens when user clicks on notification.
You need to set a pending intent on the notification itself that will open the activity:
Notification.Builder builder = new Notification.Builder(getActivity());
builder.setContentTitle("Remember to return");
builder.setContentText(title);
builder.setSmallIcon(R.drawable.ic_notification);
builder.setAutoCancel(true);
// add these lines
PendingIntent pi = PendingIntent.getActivity(
getActivity(),
REQUEST_CODE_FOR_THIS_ONE,
new Intent(getActivity(), HomeActivity.class),
0
);
builder.setContentIntent(pi);
Notification notification = builder.build();
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);
}
