I have only seen ways on how to hide a notification but not anything related to turning off sounds yet. How do I turn off/on the notification sounds from different apps installed on a device, programmatically with a button click? Is it possible for API 29 and higher versions?
You can turn off notification sound by setting your notification priority to low,
NotificationCompat.Builder mBuilder = new
NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Hello World!")
// You must set the priority to support Android 7.1 and lower
.setPriority(NotificationCompat.PRIORITY_LOW) // Set priority to
PRIORITY_LOW to mute notification sound
.setContentIntent(pendingIntent)
.setAutoCancel(true);
Another thing you can do,
myNotification.defaults = 0;
Or if you want to set your priority high and mute notification sound use,
NotificationCompat.Builder.setNotificationSilent()
then create your notification,
val builder = NotificationCompat.Builder(this, CHANNEL_ID)
.setContentText("text")
.setContentTitle("content")
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setNotificationSilent() // just keep this line
.setSmallIcon(R.drawable.logo)
.setTicker("text"))
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
builder.setChannelId(CHANNEL_ID)
}
Do not forget to uninstall and install the application
Push notifications not shows on lock screen of Xiaomi devices.
I've tried to use VISIBILITY_PUBLIC in notification builder and channel but it doesn't work.
The problem is that Xiaomi devices has special permission in apps notifications settings which permits to show notification at lock screen. But this permission is turn off by default. But in some apps like "Telegram" this permission is on by default after installation from google play, I can't find the solution how to do that.
Not sure if this helps, but I had a similar problem an a Huawei Device (API 29).
I wanted to use NotificationManager.IMPORTANCE_LOW on my NotificationChannel, but when I was trying to send Notifications on this Huawei Device, they where not Visible on the Lock Screen.
I figured out that there is an App Notification Option on this Huawei Device to use "gentle notifications". Those Notifications are not shown on the Lock Screen and this Option is turned on by Default if your Channel uses IMPORTANCE_LOW or below.
Changing the Importance of the Channel to IMPORTANCE_DEFAULT was solving my Problem.
Since I wanted IMPORTANCE_LOW because I dont wanted an Notification Sound, I just had to do a little workaround and set setSound(null, null) and setVibrationPattern(null).
NotificationChannel nChannel1 = new NotificationChannel(CHANNEL_1_ID, "Channel Name", NotificationManager.IMPORTANCE_DEFAULT);
nChannel1.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
nChannel1.setSound(null, null);
nChannel1.setVibrationPattern(null);
nChannel1.setDescription("Description");
nManager = context.getSystemService(NotificationManager.class);
nManager.createNotificationChannel(nChannel1);
Notification notification = new NotificationCompat.Builder(applicationContext, CHANNEL_1_ID)
.setContentTitle("title")
.setContentText("text")
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.build();
nManager.notify(1, notification);
I am able to create notification so:
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (notificationManager != null) {
notificationManager.notify(NOTIFICATION_ID, notification);
}
and so:
NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(MainActivity.this);
notificationManagerCompat.notify(NOTIFICATION_ID, notification);
So, what differences between these ways?
NotificationManagerCompat is a compatibility library for NotificationManager with fallbacks for older platforms.
I encourage you to take a look at the NotificationManagerCompat class since there are many different adjustments.
Generally almost all functions in NotificationManagerCompat call a compatible function in the NotificationManager.
For example function NotificationManagerCompat.notify() check for a flag EXTRA_USE_SIDE_CHANNEL. If it is false - the function simply calls NotificationManager.notify(). If set to true, the posted notification should use the side channel for delivery instead of using notification manager(Maximum sdk build version which needs support for side channeled notifications is API 19).
I'm using the startForeground() call for one of my Services:
NotificationCompat.Builder notifBuilder =
new NotificationCompat.Builder(this, "my_channel")
.setContentTitle("Loading");
startForeground(1, notifBuilder.build());
The problem is that since I'm using my unique channel for notifications and it has vibration:
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationChannel mChannel =
new NotificationChannel("my_channel", "Notifications", NotificationManager.IMPORTANCE_DEFAUL);
mChannel.enableLights(true);
mChannel.enableVibration(true);
notificationManager.createNotificationChannel(mChannel);
The startForeground() call generates vibration.
Tried some configs:
Not working:notifBuilder.setVibrate(new long[]{0,0}) nor notifBuilder.setDefaults(~Notification.DEFAULT_VIBRATE)
Working on my device notifBuilder.setVibrate(null) or using a non-registered channel id but I'm not sure if this can cause crashes in other versions or devices.
How can I avoid this vibration without declaring a new channel?
You're creating the NotificationChannel with IMPORTANCE_DEFAULT which the documentation says:
Default notification importance: shows everywhere, makes noise, but does not visually intrude.
You probably want IMPORTANCE_LOW:
Low notification importance: shows everywhere, but is not intrusive.
If you want "my_channel" to stay IMPORTANCE_DEFAULT, you can create a new channel with a different importance for this service.
The vibration pattern is specific to that notification channel, so you'd have to disable it on the notification channel when you post the notification, then reenabled it for notifications you'd like to have vibrate. You could also have separate notification channels for different priorities, as hinted to in the docs:
When you target Android 8.0 (API level 26), you must implement one or more notification channels to display notifications to your users.
So, even if you used setVibrate(null), or some other variation, it'll just be ignored on 26+, since that method has been deprecated and the NotificationChannel's pattern will now be used:
/**
* The pattern with which to vibrate.
*
* <p>
* To vibrate the default pattern, see {#link #defaults}.
* </p>
*
* #see android.os.Vibrator#vibrate(long[],int)
* #deprecated use {#link NotificationChannel#getVibrationPattern()}.
*/
#Deprecated
public long[] vibrate;
I need a program that will add a notification on Android. And when someone clicks on the notification, it should lead them to my second activity.
I have established code. The notification should be working, but for some reason it is not working. The Notification isn't showing at all. I don't know what am I missing.
Code of those files:
Notification n = new Notification.Builder(this)
.setContentTitle("New mail from " + "test#gmail.com")
.setContentText("Subject")
.setContentIntent(pIntent).setAutoCancel(true)
.setStyle(new Notification.BigTextStyle().bigText(longText))
.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Hide the notification after it's selected
notificationManager.notify(0, n);
The code won't work without an icon. So, add the setSmallIcon call to the builder chain like this for it to work:
.setSmallIcon(R.drawable.icon)
Android Oreo (8.0) and above
Android 8 introduced a new requirement of setting the channelId property by using a NotificationChannel.
NotificationManager mNotificationManager;
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(mContext.getApplicationContext(), "notify_001");
Intent ii = new Intent(mContext.getApplicationContext(), RootActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, ii, 0);
NotificationCompat.BigTextStyle bigText = new NotificationCompat.BigTextStyle();
bigText.bigText(verseurl);
bigText.setBigContentTitle("Today's Bible Verse");
bigText.setSummaryText("Text in detail");
mBuilder.setContentIntent(pendingIntent);
mBuilder.setSmallIcon(R.mipmap.ic_launcher_round);
mBuilder.setContentTitle("Your Title");
mBuilder.setContentText("Your text");
mBuilder.setPriority(Notification.PRIORITY_MAX);
mBuilder.setStyle(bigText);
mNotificationManager =
(NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
// === Removed some obsoletes
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
String channelId = "Your_channel_id";
NotificationChannel channel = new NotificationChannel(
channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_HIGH);
mNotificationManager.createNotificationChannel(channel);
mBuilder.setChannelId(channelId);
}
mNotificationManager.notify(0, mBuilder.build());
Actually the answer by ƒernando Valle doesn't seem to be correct. Then again, your question is overly vague because you fail to mention what is wrong or isn't working.
Looking at your code I am assuming the Notification simply isn't showing.
Your notification is not showing, because you didn't provide an icon. Even though the SDK documentation doesn't mention it being required, it is in fact very much so and your Notification will not show without one.
addAction is only available since 4.1. Prior to that you would use the PendingIntent to launch an Activity. You seem to specify a PendingIntent, so your problem lies elsewhere. Logically, one must conclude it's the missing icon.
You were missing the small icon.
I did the same mistake and the above step resolved it.
As per the official documentation:
A Notification object must contain the following:
A small icon, set by setSmallIcon()
A title, set by setContentTitle()
Detail text, set by setContentText()
On Android 8.0 (API level 26) and higher, a valid notification channel ID, set by setChannelId() or provided in the NotificationCompat.Builder constructor when creating a channel.
See http://developer.android.com/guide/topics/ui/notifiers/notifications.html
This tripped me up today, but I realized it was because on Android 9.0 (Pie), Do Not Disturb by default also hides all notifications, rather than just silencing them like in Android 8.1 (Oreo) and before. This doesn't apply to notifications.
I like having DND on for my development device, so going into the DND settings and changing the setting to simply silence the notifications (but not hide them) fixed it for me.
Creation of notification channels are compulsory for Android versions after Android 8.1 (Oreo) for making notifications visible. If notifications are not visible in your app for Oreo+ Androids, you need to call the following function when your app starts -
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 behaviours after this
NotificationManager notificationManager =
getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
}
You also need to change the build.gradle file, and add the used Android SDK version into it:
implementation 'com.android.support:appcompat-v7:28.0.0'
This worked like a charm in my case.
I think that you forget the
addAction(int icon, CharSequence title, PendingIntent intent)
Look here: Add Action
I had the same issue with my Android app. I was trying out notifications and found that notifications were showing on my Android emulator which ran a Android 7.0 (Nougat) system, whereas it wasn't running on my phone which had Android 8.1 (Oreo).
After reading the documentation, I found that Android had a feature called notification channel, without which notifications won't show up on Oreo devices. Below is the link to official Android documentation on notification channels.
Notifications Overview, Notification anatomy
Create and Manage Notification Channels
For me it was an issue with deviceToken. Please check if the receiver and sender device token is properly updated in your database or wherever you are accessing it to send notifications.
For instance, use the following to update the device token on app launch. Therefore it will be always updated properly.
// Device token for push notifications
FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(
new OnSuccessListener<InstanceIdResult>() {
#Override
public void onSuccess(InstanceIdResult instanceIdResult) {
deviceToken = instanceIdResult.getToken();
// Insert device token into Firebase database
fbDbRefRoot.child("user_detail_profile").child(currentUserId).child("device_token")).setValue(deviceToken)
.addOnSuccessListener(
new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
}
});
}
});
I encountered a similar problem to yours and while searching for a solution I found these answers but they weren't as direct as I hoped they would be but it gives an Idea; Your notifications may not be showing because for versions >=8 notifications are done relatively differently there is a NotificationChannel which aids in managing notifications this helped me. Happy coding.
void Note(){
//Creating a notification channel
NotificationChannel channel=new NotificationChannel("channel1",
"hello",
NotificationManager.IMPORTANCE_HIGH);
NotificationManager manager=(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.createNotificationChannel(channel);
//Creating the notification object
NotificationCompat.Builder notification=new NotificationCompat.Builder(this,"channel1");
//notification.setAutoCancel(true);
notification.setContentTitle("Hi this is a notification");
notification.setContentText("Hello you");
notification.setSmallIcon(R.drawable.ic_launcher_foreground);
//make the notification manager to issue a notification on the notification's channel
manager.notify(121,notification.build());
}
Make sure your notificationId is unique. I couldn't figure out why my test pushes weren't showing up, but it's because the notification ids were generated based on the push content, and since I was pushing the same notification over and over again, the notification id remained the same.
Notifications may not be shown if you show the notifications rapidly one after the other or cancel an existing one, then right away show it again (e.g. to trigger a heads-up-notification to notify the user about a change in an ongoing notification). In these cases the system may decide to just block the notification when it feels they might become too overwhelming/spammy for the user.
Please note, that at least on stock Android (tested with 10) from the outside this behavior looks a bit random: it just sometimes happens and sometimes it doesn't. My guess is, there is a very short time threshold during which you are not allowed to send too many notifications. Calling NotificationManager.cancel() and then NotificationManager.notify() might then sometimes cause this behavior.
If you have the option, when updating a notification don't cancel it before, but just call NotificationManager.notify() with the updated notification. This doesn't seem to trigger the aforementioned blocking by the system.
If you are on version >= Android 8.1 (Oreo) while using a Notification channel, set its importance to high:
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);
val pendingIntent = PendingIntent.getActivity(applicationContext, 0, Intent(), 0)
var notification = NotificationCompat.Builder(applicationContext, CHANNEL_ID)
.setContentTitle("Title")
.setContentText("Text")
.setSmallIcon(R.drawable.icon)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setContentIntent(pendingIntent)
.build()
val mNotificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
mNotificationManager.notify(sameId, notification)
