I'm trying to create a notification, without using the NotificationCompat.Builder. The motivation is not using the Support Library if its not really needed (and also for educational purposes)
I assume that its possible, as there are "native" Notification and NotificationManager classes that are exposed to the users.
My try goes as follow:
Intent i = new Intent();
i.setClassName("com.test", "com.test.SomeActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK );
PendingIntent pi = PendingIntent.getService(this, 0, i, 0);
notification.setLatestEventInfo(this, title, content,pi);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0 , notification);
This code just run, but no notification appears, and notificationManager.notify() in general returns void.

I need display notifications when my server return specific values. I have a service running on android and taskschedule running every time sending request to server, when the server return positive value i need display message on celular display, similar receive message of whatsapp (display icon and notification on display). Anyone have a sample?
I trying this:
PendingIntent resultPendingIntent = PendingIntent.getActivity(
this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
But my application is running as a service.
Please use Using Service to run background and create notification
private void processStartNotification() {
// Do something. For example, fetch fresh data from backend to create a rich notification?
final NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentTitle("Scheduled Notification")
.setAutoCancel(true)
.setColor(getResources().getColor(R.color.colorAccent))
.setContentText("This notification has been triggered by Notification Service")
.setSmallIcon(R.drawable.notification_icon);
PendingIntent pendingIntent = PendingIntent.getActivity(this,
NOTIFICATION_ID,
new Intent(this, NotificationActivity.class),
PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
builder.setDeleteIntent(NotificationEventReceiver.getDeleteIntent(this));
final NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(NOTIFICATION_ID, builder.build());
}
guys.
I've been debugging this for days, but I can't find an answer for this.
As the title says, I am using BroadcastReceiver to make my notification.
Everything was fine until I add .addAction.
It needs PendingIntent for default and I made a PendingIntent.
But the problem is this; when I add .addAction, It says this
Incompatiable types.
Required : android.app.Notification
Found : android.app.Notification.Builder
the code works perfectly fine with out the .addAction and the PendingIntent.
What could be the problem?
Here is my code,
BroadcastReceiver, WifiService.java
Intent intent = new Intent(mcontext, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pIntent = PendingIntent.getActivity(mcontext, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Notification noti = new Notification.Builder(mcontext)
.setContentTitle("Welcome home!")
.setContentText("You have a to-do; " + hometodo)
.setSmallIcon(R.drawable.home_light)
.setLargeIcon(icon)
.setLights(0xFFFFD800, 5000, 0)
.addAction(R.drawable.archive_notification, "Mark as done", pIntent);
//.addAction gets the error.
.build();
NotificationManager notificationManager = (NotificationManager) mcontext.getSystemService(mcontext.NOTIFICATION_SERVICE);
notificationManager.notify(0, noti);
used NotificationCompat for setting .addAction(...).
Check official docs
action buttons won't appear on platforms prior to Android 4.1. Action
buttons depend on expanded notifications, which are only available in
Android 4.1 and later.
I was wondering if anyone has some experience with with this type of Notification.
In my use case I want to trigger a notification from my Service and than it should open a fullscreen video. The method setFullScreenIntent look just the right thing for this problem because in the documentation it writes:
An intent to launch instead of posting the notification to the status bar. Only for use with extremely high-priority notifications demanding the user's immediate attention, such as an incoming phone call or alarm clock that the user has explicitly set to a particular time.
So it says it works like an incoming phone call. That means even if my phone is asleep I should get to see the notification in full screen.
But in my case I just get the heads-up notification and if I click on it it opens the activity. Even thought in the docs they mention something about this behavior ...
On some platforms, the system UI may choose to display a heads-up notification, instead of launching this intent, while the user is using the device.
... I want to know how to automatically open the activity when the notification is triggered. Just like the incoming phone call screen.
This is my code from the service:
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Intent notificationIntent = new Intent("android.intent.category.LAUNCHER");
intent.setClassName("com.example.test",
"com.example.test.VideoActivity");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(contentIntent)
.setContentTitle("Video")
.setContentText("Play video")
.setFullScreenIntent(contentIntent, true);
NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, mBuilder.build());
return Service.START_STICKY;
}
try to notify notification with setFullScreenIntent at onCreate
#Override
public int onCreate() {
Intent notificationIntent = new Intent("android.intent.category.LAUNCHER");
intent.setClassName("com.example.test",
"com.example.test.VideoActivity");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(contentIntent)
.setContentTitle("Video")
.setContentText("Play video")
.setFullScreenIntent(contentIntent, true);
NotificationManager mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, mBuilder.build());
}
Try removing
.setContentIntent(contentIntent)
I can use the following code to display a notification icon of missed calls, I hope to click the icon to open system Missed Calls UI, how can I do ? Thanks!
At present, I can open ui.CallerMain.class UI if I remove the comment.
BTW, in system Missed Calls UI, missed calls are listed in there.
private void ShowMissCallNotification(Context myContext,String myContentText) {
NotificationManager notificationManager = (NotificationManager) myContext.getSystemService(android.content.Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(android.R.drawable.sym_call_missed,
myContext.getString(R.string.app_name),
System.currentTimeMillis());
notification.flags |= Notification.FLAG_ONGOING_EVENT;
notification.flags |= Notification.FLAG_NO_CLEAR;
CharSequence contentTitle= "Title";
CharSequence contentText =myContentText;
//Intent notificationIntent = new Intent(myContext, ui.CallerMain.class);
//PendingIntent contentItent = PendingIntent.getActivity(myContext, 0, notificationIntent, 0);
//notification.setLatestEventInfo(myContext, contentTitle, contentText,contentItent);
notificationManager.notify(NotificationID, notification);
}
Set a Pending Intent to the notification which will trigger the Call History.
First create an intent with Call Log
Intent resultIntent = new Intent();
resultIntent.setAction(Intent.ACTION_VIEW);
resultIntent.setType(CallLog.Calls.CONTENT_TYPE);
Then obtain the PendingIntent
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
this,
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
Then set the PendingIntent to your notification builder
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
.setSmallIcon()
.setContentTitle()
.setContentText()
.setContentIntent(resultPendingIntent);
notificationManager.notify(id, builder.build());
Now clicking the notification will open the Call Log.
Update: The code commented out in your snippet will work if you create the Intent as mentioned above in this answer. But please be aware that the method by which you are creating notification has been deprecated. Use NotificationCompat class from the support library in future.
My app is getting called by an intent that is passing information(pendingintent in statusbar) but when I hit the home button and reopen my app by holding the home button it calls the intent again and the same extras are still there...
is there any way to clear the intent? or check whether it has been used before?
Intent intent = new Intent(context, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("reportID", reportID);
intent.putExtra("message", message);
intent.putExtra("toast_show", true);
intent.putExtra("detail_open", true);
intent.putExtra("SplashActivity", true);
PendingIntent pendingIntent = PendingIntent
.getActivity(context.getApplicationContext(), 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT
| PendingIntent.FLAG_ONE_SHOT);
// Intent.FLAG_ACTIVITY_NEW_TASK
/* get the system service that manage notification NotificationManager */
NotificationManager notificationManager = (NotificationManager) context
.getApplicationContext().getSystemService(
Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(
context.getApplicationContext())
.setWhen(when)
.setContentText(message)
.setContentTitle(title)
.setSmallIcon(smalIcon)
.setAutoCancel(true)
.setTicker(message)
.setLargeIcon(largeIcon)
.setDefaults(
Notification.DEFAULT_LIGHTS
| Notification.DEFAULT_VIBRATE
| Notification.DEFAULT_SOUND)
.setContentIntent(pendingIntent);
/* Create notification with builder */
Notification notification = notificationBuilder.build();
notificationManager.notify(0, notification);
The problem starts when I receive a notification. If I start the app from the notification, it starts the correct screen and I can use the app => ok. But when I quit the app (with home or back button) it do not appears anymore in the "recent app" list. More precisely:
Does anyone knows how to keep the app in the "recent app" list after being started form a notification?
Update this line and try
PendingIntent pendingIntent = PendingIntent.getActivity(context, (int)(Math.random() * 100),intent,PendingIntent.FLAG_UPDATE_CURRENT);
What you need is the PendingIntent.FLAG_CANCEL_CURRENT :
If the described PendingIntent already exists, the current one is canceled before generating a new one. You can use this to retrieve a new PendingIntent when you are only changing the extra data in the Intent; by canceling the previous pending intent, this ensures that only entities given the new data will be able to launch it.
PendingIntent pendingIntent = PendingIntent.getActivity(
context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
This will ensure that your latest data will pe present on your Intent.
