I create a Notification using NotificationCompat.Builder. That notification gets an action button:
notification = notificationBuilder
.setContentTitle(getString(R.string.blabla)).
.setContentText("")
.setSmallIcon(R.drawable.blabla)
.setContentIntent(pendingIntentOpenApp)
.addAction(android.R.drawable.ic_menu_close_clear_cancel, "Cancel", pendingIntentAction)
.build();
The notification displays, but the action is repeated three times:
I cannot figure out what I am doing wrong, so I appreciate any help.
You can create notification by using following code:
var mBuilder = NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle("Title")
.setContentText("Description")
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.addAction(R.drawable.ic_notification,"OK",pendingIntent)
.setChannelId(chanelId).build()
val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val mChanel = NotificationChannel(id, name, NotificationManager.IMPORTANCE_HIGH)
notificationManager.createNotificationChannel(mChanel)
notificationManager.notify(channelId, mBuilder)
}else{
notificationManager.notify(channelId, mBuilder)
}

Code:
here is the code to popup notification on button click
notificationbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "noti", Toast.LENGTH_SHORT).show();
Intent i=new Intent(getActivity(),OrderTrack.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(getActivity(),(int) Calendar.getInstance().getTimeInMillis(),i,0);
Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.half_bicycle);
Notification builder=new NotificationCompat.Builder(getActivity(),"1")
.setSmallIcon(R.drawable.half_bicycle)
.setContentTitle("title")
.setContentText("Text")

});
Here I am trying to use BigPictureSt
yle notification. I hava tried two variation of code. But both doesn't give any result/notification.
All the above code is inside a fragment.Is this a reason why it's not working?
I have set the App style to NoActionBar.Is this a reason why it's not working?
Please answer this questions with a proper solution !!!!
Adding the Following code doesn't solve the problem
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(getActivity());
notificationManager.notify(101, notif);
The code is fine and there is nothing wrong with it but most importantly you forgot to show the notification itself i.e you are not using the objects that are created.
So show the notification like this...
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(getActivity());
notificationManager.notify(101, notif);//101 is notification id
EDIT:
If you are targetting Android Oreo and above you need to create the channels for notification like this. Use this function to create notification channel and set this channel id on a notification while creating it...
String channelId = "some_channel_id";
private void createNotificationChannel() {
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
CharSequence name = getString(R.string.channel_name);
String description = getString(R.string.channel_description);
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);
channel.setDescription(description);
// Register the channel with the system; you can't change the importance
// or other notification behaviors after this
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
}
Complete code:
notificationbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
createNotificationChannel(); //Create notification channel
Toast.makeText(getContext(), "noti", Toast.LENGTH_SHORT).show();
Intent i=new Intent(getActivity(),OrderTrack.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(getActivity(),(int) Calendar.getInstance().getTimeInMillis(),i,0);
Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.half_bicycle);
Notification builder=new NotificationCompat.Builder(getActivity(),"1")
.setSmallIcon(R.drawable.half_bicycle)
.setContentTitle("title")
.setContentText("Text")
.setLargeIcon(bitmap)
.setChannelId(CHANNEL_ID) // Channel Id
.setStyle(new NotificationCompat.BigPictureStyle()
.bigPicture(bitmap)
.bigLargeIcon(null))
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.setOnlyAlertOnce(true)
.build();
Notification notif = new Notification.Builder(getContext())
.setContentTitle("New photo from ")
.setContentText("subject")
.setSmallIcon(R.drawable.half_bicycle)
.setLargeIcon(bitmap)
.setChannelId(CHANNEL_ID) // Channel Id
.setStyle(new Notification.BigPictureStyle()
.bigPicture(bitmap))
.build();
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(getActivity());
notificationManager.notify(101, notif);//101 is notification id
}
});

I'm trying to achieve a foreground service.
my problem is my notification doesn't appear in the lock screen.
I try to set visibility to PUBLIC but it doesn't work.
#RequiresApi(api = Build.VERSION_CODES.O)
private String createNotificationChannel() {
NotificationChannel notificationChannel =
new NotificationChannel(
"channelId",
"channelName",
NotificationManager.IMPORTANCE_DEFAULT);
notificationChannel.setDescription("channelDescription");
notificationChannel.setLockscreenVisibility(NotificationCompat.VISIBILITY_PUBLIC);
NotificationManagerCompat service = NotificationManagerCompat.from(getBaseContext());
service.createNotificationChannel(notificationChannel);
return "myChannelId";
}
public void startForeground() {
Intent notificationIntent = new Intent(this, HomeActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
String channelID = "";
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
channelID = createNotificationChannel();
}
Notification notification = new NotificationCompat.Builder(this, channelID)
.setContentTitle(title)
.setContentText(content)
.setShowWhen(false)
.setSmallIcon(R.drawable.ic_notification_small_icon)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.setContentIntent(pendingIntent)
.build();
startForeground("notificationId", notification);
}
notification.setOngoing(true)
makes the notification visible on your lock screen.
Code
Notification notification = new NotificationCompat.Builder(this, channelID)
.setContentTitle(title)
.setContentText(content)
.setShowWhen(false)
.setSmallIcon(R.drawable.ic_notification_small_icon)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.setContentIntent(pendingIntent)
.setOngoing(true)
.build();
if that doesn't work check your device settings.

I try to create android notification, when i click in a button but does not work.
this is the code that i write in button
NotificationManager Nm;
public void Notify(View view) {
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setContentTitle("LOGIN")
.setContentText("You are login successfully")
.setSmallIcon(R.drawable.done);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, mBuilder.build());
}
As already stated by Ikazuchi, for android versions since android 8 you'll need to add a notification channel. This can be done, as it's shown in the documentation here: https://developer.android.com/training/notify-user/build-notification#java, like this:
createNotificationChannel();
Notification notification = new NotificationCompat.Builder(this, "channelID")
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Much longer text that cannot fit one line...")
.build();
private void createNotificationChannel() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel serviceChannel = new NotificationChannel(
"channelID",
"Channel Name",
importance
);
NotificationManager manager = getSystemService(NotificationManager.class);
manager.createNotificationChannel(serviceChannel);
}
}

non removable notification
(4 answers)
Closed 4 years ago.
I am working on music application so i need to display notification on notification bar. for that i am using custom notification. The following is the code for notification for Android Oreo
String NOTIFICATION_CHANNEL_ID = "001";
RemoteViews notificationLayout = new RemoteViews(getPackageName(), R.layout.mynotification);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications", NotificationManager.IMPORTANCE_LOW);
notificationChannel.setDescription("Channel description");
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.createNotificationChannel(notificationChannel);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(MainActivity.this, NOTIFICATION_CHANNEL_ID);
notificationBuilder.setSmallIcon(R.drawable.exo_edit_mode_logo)
.setCustomContentView(notificationLayout)
.setAutoCancel(true)
.setPriority(Notification.PRIORITY_DEFAULT);
NotificationManagerCompat com = NotificationManagerCompat.from(this);
com.notify(001, notificationBuilder.build());
}
This code is working fine, but when swipe the notification from notification bar it will be removed. But my requirement is not remove when swipe the notification.
I tried with setAutoCancel(true) and setAutoCancel(false). But not working it will be removed. So how to stick the notification here.
Please guide me how to do this.
Thanks In Advance
use setOngoing(true) to achieve this
You have to add this setOngoing(true)
Try:
Notification.Builder builder = new Notification.Builder(this, CHANNEL_ID)
.setContentTitle(getString(R.string.app_name))
.setContentText("Text")
.setSmallIcon(R.mipmap.ic_launcher)
.setAutoCancel(false)
.setOngoing(true);
Notification notification = builder.build();
I have a simple method which onclick() of a Button should generate status bar notification, but for some reason, it isn't showing up.
public void createNotification() {
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
.setSmallIcon(android.R.drawable.ic_dialog_alert)
.setContentTitle("Notification!")
.setContentText("This is my first notification!");
Notification notification = builder.build();
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(0, notification);
}
In Android 8 (API level 26), all notifications must be assigned to a channel.
This work for me:
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getContext(), CHANNEL_ID)
.setSmallIcon(R.drawable.emo_no_paint_120)
.setContentTitle("title")
.setContentText("content")
.setColor(Color.parseColor("#009add"))
.setAutoCancel(true);
NotificationManager notificationManager = (NotificationManager) getContext().getSystemService(
NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
notificationManager.createNotificationChannel(mChannel);
}
notificationManager.notify(0, mBuilder.build());
And you should add AppCompat library
implementation 'com.android.support:support-compat:27.1.0'
You could check official Android Docs
Your code is okay. But since you are targeting Android 8.0, you need to implement Notification Channels since this the preferred way in Android Oreo.
