Android push notification icon LIght theme issue

I know this question is asked so many time related to Push notification status bar icon, but my problem is a little bit different.
I am using FCM push notification, my notification is coming properly. I have set notification icon for pre-lollipop and more then lollipop version. My notification icon is showing properly in dark theme devices like MOTO-G 5+, but when I check the same notification on light theme device like Samsung Galaxy Edge 7.0, my notification icon turns white as per app theme, but in another app, the notification icon is looking properly. I saw many example solution, but they did not help with my problem.
I am using following code :
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ila_app_icon);
long when = System.currentTimeMillis();
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setContentText(message)
.setContentIntent(pendingIntent)
// .setColor(getNotificationColor())
.setSmallIcon(getNotificationIcon(notificationBuilder))
.setWhen(when)
.setSound(defaultSoundUri)
.setLargeIcon(bitmap);
Random random = new Random();
int uniqueIntegerNumber = random.nextInt(9999 - 1000) + 1000;
notificationManager.notify(uniqueIntegerNumber, notificationBuilder.build());
Get notification icon method :-
private int getNotificationIcon(NotificationCompat.Builder notificationBuilder) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
int color = 0x008000;
notificationBuilder.setColor(color);
return R.drawable.notification_white;
}
return R.drawable.ila_app_icon;
}
I also tried setColor property, but that also doesn't work.
1) Light Theme ( Here the white flag icon )
Here is the screen shot :-
2) Dark Theme :-

After all searching and other things i found my solution,everything was working well expect the notification icon, the icon was keeping little bit pixel of different color.
We can create the notification icon from the following link, it makes our icon transparent for notification
https://romannurik.github.io/AndroidAssetStudio/icons-notification.html#source.type=clipart&source.clipart=ac_unit&source.space.trim=1&source.space.pad=0&name=ic_stat_ac_unit

notification disappears after showing

We have code similar to the following in our app
val pendingIntent = PendingIntent.getActivity(ctx, id.toInt(), intent, PendingIntent.FLAG_CANCEL_CURRENT)
val builder = NotificationCompat.Builder(ctx, Channel.TEST_CHANNEL.channelId)
builder.setTicker(tickerText)
.setContentTitle(contentTitle)
.setContentText(contentText)
.setVibrate(vibrate)
.setSmallIcon(icon)
.setAutoCancel(true)
.setLights(-0xff0100, 300, 1000)
.setSound(uri)
.setContentIntent(pendingIntent)
.setStyle(NotificationCompat.BigTextStyle().bigText(contentText))
.addAction(R.drawable.ic_notification, ctx.getString(R.string.notification), piAction)
val notification = builder.build()
val nf = ctx.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
nf.notify(NOTIFICATION_TAG, id.toInt(), notification)
}
Starting recently we noticed that notifications on some device running Android 8+ started disappearing briefly after being shown, without user's interaction. Setting auto-cancel to false helps, but the user experience degrades.
The id is a unique item id from the database. This may be important thing to note - technically we can have a notification with such id be shown, removed/canceleld by user, and later some time used again for a similar notification with the same id. Can this be the reason?

We've updated the support libs and tried the following method on builder for luck:
builder.setTicker(tickerText)
...
.setTimeoutAfter(-1)
...
Setting this param to a positive value delayed the notification disappearing by that amount of time (so it did affect). Thus we tried a negative number, the notifications seem to stay there now.
I couldn't find any reasonable documentation explaining this, so this answer is not 100%, but keeping it here for now for others to try and see if it helps them.

Disable your application from auto optimize from battery optimization setting in android OREO. Notification will stay as long as you want

Only thing I found uncertain is NotificationCompat.Builder
Android oreo now uses Notification.Builder instead of NotificationCompat.Builder.
Might be you have to check android version like:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
//Use Notification.Builder
} else {
// Use NotificationCompat.Builder.
}
I don't think unique id will be an issue for disappearing notification.
Google has created open source sample for this new changes. Please refer to it for more info.
https://github.com/googlesamples/android-NotificationChannels

.setAutoCancel(false)
May be it will work for you.

Android Notification Not working on Android 6.0 (Marshmallow)

I'm implementing local notification on Android and I have the problem that they are not appearing on Android 6.0 (Samsung S7).
I was searching for solutions, but I coulnd't find anything for this problem. I have the icon in the proper res/drawable folder, also I have defined a notification title, text, ringtone (raw folder) but it's not showing up...
There is my code:
Context acontext = getApplicationContext();
PackageManager pm = acontext.getPackageManager();
Intent notificationIntent = pm.getLaunchIntentForPackage(acontext.getPackageName());
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(acontext, 0, notificationIntent, 0);
int notification_icon = acontext.getResources().getIdentifier("icon", "drawable", acontext.getPackageName());
int notificationID = 0;
// Build notification
Notification noti = new Notification.Builder(acontext)
.setContentTitle("Title")
.setContentText("Incoming text")
.setSmallIcon(notification_icon)
.setContentIntent(pendingIntent)
.setLights(Color.RED, 1, 1)
.build();
NotificationManager notificationManager = (NotificationManager) acontext.getSystemService(Context.NOTIFICATION_SERVICE);
// hide the notification after its selected
noti.sound = Uri.parse("android.resource://" + acontext.getPackageName() + "/raw/incoming");
noti.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(notificationID, noti);
Did anyone else experience this problem? Any help would be appreciated. Thank you.

There are some changes in new notification. new NotificationCompat.Builder(this) is deprecated and need NotificationChannelfor android oreo above. You can try this solution.
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("Title");
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);
NotificationManager mNotificationManager =
(NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel("notify_001",
"Channel human readable title",
NotificationManager.IMPORTANCE_DEFAULT);
mNotificationManager.createNotificationChannel(channel);
}
mNotificationManager.notify(0, mBuilder.build());

There are various layers involved in showing notifications in Android, Please first check if this works for other devices of same OS version. Normally these kind of issues are device specific not OS specific, Also check notification logs how to check notification logs in android ?
If issue is device specific, following can be handy tips:
Check notifications not blocked for your app by device settings.
Check power settings blocking non-priority notifications.
If there are notifications in logs but not showing up, there can be some issue with your internal OS settings/configs. (believe me Android is not very clean OS)
If you can, try factory resetting your device. (In my case this worked)

Google Play Services must be enabled in order to receive push notifications on your Android device. If Google Play Services are enabled and the general troubleshooting steps have not resolved the issue, it may be necessary to reset the app. To reset the app, go to Settings → Apps → PagerDuty and tap Clear Data.
For Android 6.0 and newer, make sure the app is set as a prioritized app in priority mode.
For Android 6.0 and newer, check to see if the app is being silenced by Doze mode.

Check the android version accordingly set the icon for > 6.0 and for other.For 6.0 version we need white background icon.
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
icon = R.mipmap.your_logo_for_Lolipop;
}else{
icon = R.drawable.your_logo_for_Kitkat ;
}

Android notification is not showing

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)

Status bar notification plugin error with Cordova

I'm trying to add the Status Bar Notification Plugin for Cordova to my Android App, but I get an error with it's code.
Here's the problematic code:
Notification noti = new Notification.Builder(context)
.setContentTitle(contentTitle)
.setContentText(contentText)
.setSmallIcon(icon)
.build();
The error is on the .build(), Eclipse tells me:
"The method build() is undefined for the type Notification.Builder"

I am having the same issue. It looks like a mismatch the sdk versions and now depreciated methods.
getNotification() is the method to call since API 11
build() was added in API 16
if you are like me, you are using a version < 16, so use .getNotification() instead.
Im not going to worry about API 16 right now but I bet if I download 16 and set my target to such, build() will work.
Let me know if it works for you.

For me .getNotification() didn't resolve the problem, because I need a solution for API 10 and higher.
I found a way to deal with it. If someone else has the same issue, I recommend to do this :
1) Go through instructions for StatusBarNotification (click)
2) Modify StatusBarNotification.java
Add
private Notification noti;
private PendingIntent contentIntent;
At the bottom of StatusBarNotification class, for example before NotificationManager declaration
Modify showNotification method
Comment or delete:
import android.app.Notification.Builder;
and
Notification noti = new Notification.Builder(context)
.setContentTitle(contentTitle)
.setContentText(contentText)
.setSmallIcon(icon)
.build();
Instead of this part, paste:
noti = new Notification(android.R.drawable.btn_star_big_on, contentText, System.currentTimeMillis() );
noti.flags = Notification.FLAG_AUTO_CANCEL;
Intent notificationIntent = new Intent(context, !yourMainActivityClass!.class);
notificationIntent.setAction(Intent.ACTION_MAIN);
notificationIntent = notificationIntent.setFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
noti.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
Change !yourMainActivityClass! to your class
Add calling method in index.html For tests you can make JQM button with
onclick='window.plugins.statusBarNotification.notify("Put your title
here", "Put your message here");return false;'
I know that this solution is using depreciated methods, but I spent a lof of hours to make it works and I didn't see another solution for API 10. If somebody has better idea, share with me ;)
