I'm learning Notifications, I use Android Studio 4.0 with latest androidx.core.app.NotificationManagerCompat.
There is a sample code about Notifications in the project user-interface-samples.
I find there are many differents about Notifications between this androidx and previous API.
Must the Notifications style be the one of BigTextStyleNotification, BigPictureStyleNotification, InboxStyleNotification and MessagingStyleNotification ?
Following are the notification styles available :
Notification.BigPictureStyle, Notification.BigTextStyle,
Notification.DecoratedCustomViewStyle, Notification.InboxStyle,
Notification.MediaStyle, Notification.MessagingStyle
You can get more info on this link.
Just for information purposes, to create a notification without hustle and get all predefined formatting in one place, just do the following :
Go to the Project Tab of android studio and right click.
Click on New -> UI Component -> Notification
Enter the required notification name
To call this notification just enter the following :
<NotificationClassName>.createNotification(getApplicationContext());
This is for a general notification app. I've managed to capture and set the large icon for the notification since it accepts a Bitmap type as a parameter, but setting the small icon is proving to be a lot more tricky. It only accepts an int resource ID. Since I have no idea what application might be sending a notification to my listener, I would have to generate it dynamically. I can get the small icon by listening for incoming notifications and extracting it, but I can't seem to find a way to set it via its resource ID.
I don't think it's possible, but just want to confirm. If so, is there a workaround, or would I have to manually load small icons of specific apps I want to support into my Drawable folder and then use the resource Id from there? That sounds like a hassle seeing that I've already gotten the right icon, but can't load it in! Below is my code:
public class NotificationService extends NotificationListenerService {
#Override
public void onNotificationPosted(StatusBarNotification sbn) {
Bundle extras = sbn.getNotification().extras;
int id1 = extras.getInt(Notification.EXTRA_SMALL_ICON);;
//Building Notifications
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context.getApplicationContext(id1))
.setSmallIcon(R.mipmap.ic_launcher) //This gives an error
.setContentTitle("My Title")
.setContentText("My Text");
NotificationManager notificationManager =
(NotificationManager) context.getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(notiId, mBuilder.build());
}
}
Small icon might not load if it exceeds the size prescribed by Android.Generally we can load small icons through images stored in resource folder only.
can get the details regarding icon sizes for push notifications from the following link
GCM Push Notification Large Icon size
Small Icons in push notifications cannot be added dynamically. Large Icons can be added dynamically by running an Async task. Application will crash if there is no small icon. Small Icon is mandatory for PushNotification.
When using Parse for push notifications our app always displayed the application's launcher icon.
In the latest Android 5.1 version, the icon appears to be blank (a white square).
I tried setting the icon in the meta data:
<meta-data android:name="com.parse.push.notification_icon" android:resource="#drawable/noti_icon"/>
Based on the question here
But nothing seems to work.
Any ideas?
You must use a transparent and white icon under Android Lollipop 5.0 or greater. You can extend ParsePushBroadcastReceiver class and override the two methods to get your notification icon compatible with these Android APIs.
#Override
protected int getSmallIconId(Context context, Intent intent) {
return R.drawable.your_notifiation_icon;
}
#Override
protected Bitmap getLargeIcon(Context context, Intent intent) {
return BitmapFactory.decodeResource(context.getResources(), R.drawable.your_notifiation_icon);
}
Remember to customize your code to support Lollipop and previous APIs.
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
return BitmapFactory.decodeResource(context.getResources(), R.drawable.your_notifiation_icon_lollipop);
}
else{
return BitmapFactory.decodeResource(context.getResources(), R.drawable.your_notifiation_icon);
}
It is not related to Parse or push nitification, but just how Android 5.0 handles notification icons.
See this releated question for details:
Notification bar icon turns white in Android 5 Lollipop
Although #Pelanes has the correct answer (and should be accepted), here's what I did. Note that the Parse docs for getSmallIconId state the following:
Retrieves the small icon to be used in a Notification. The default implementation uses the icon specified by com.parse.push.notification_icon meta-data in your AndroidManifest.xml with a fallback to the launcher icon for this package. To conform to Android style guides, it is highly recommended that developers specify an explicit push icon.
So it is not entirely necessary to override the getSmallIconId() and getLargeIcon() methods.
What I did to solve the problem was I just made a copy of my icon, punched transparent "holes" into the icon, and set the com.parse.push.notification_icon meta-data in my manifest to point to this new icon.
For Android 5.0, it is required for your notification icon to be white and transparent, as others have mentioned. So creating the separate icon is necessary. One line in the manifest and one new drawable file is all it takes.
Try this code.
Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setLargeIcon(largeIcon)
.setContentText(data)
.setContentTitle("Notification from Parse")
.setContentIntent(pendingIntent);
I'm seeing the following exception in crash logs:
android.app.RemoteServiceException: Bad notification posted from package com.my.package: Couldn't create icon: StatusBarIcon(pkg=com.my.package user=0 id=0x7f02015d level=0 visible=true num=0 )

I'm posting my Notification from an IntentService from a PendingIntent set via the AlarmManager using the following method. All values passed in here are from the bundle extras in the PendingIntent / IntentService.
/**
* Notification
*
* #param c
* #param intent
* #param notificationId
* #param title
* #param message
* #param largeIcon
* #param smallIcon
*/
public static void showNotification(Context c, Intent intent,
int notificationId, String title, String message, int largeIcon,
int smallIcon) {
PendingIntent detailsIntent = PendingIntent.getActivity(c,
notificationId, intent, PendingIntent.FLAG_UPDATE_CURRENT);
// BUILD
NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(
c);
// TITLE
mNotifyBuilder.setContentTitle(title).setContentText(message);
// ICONS
mNotifyBuilder.setSmallIcon(smallIcon);
if (Util.isAndroidOSAtLeast(Build.VERSION_CODES.HONEYCOMB)) {
Bitmap large_icon_bmp = ((BitmapDrawable) c.getResources()
.getDrawable(largeIcon)).getBitmap();
mNotifyBuilder.setLargeIcon(large_icon_bmp);
}
mNotifyBuilder.setContentIntent(detailsIntent);
mNotifyBuilder.setVibrate(new long[] { 500, 1500 });
mNotifyBuilder.setTicker(message);
mNotifyBuilder.setContentText(message);
// NOTIFY
NotificationManager nm = (NotificationManager) c
.getSystemService(Context.NOTIFICATION_SERVICE);
nm.notify(notificationId, mNotifyBuilder.build());
}
From what I've seen of other answers - the exception I'm seeing happens when setSmallIcon() is not called properly.
I've checked and double checked that the Resource IDs being passed are all correct.
What was happening was, I was including the integer reference to the icon in the PendingIntent bundle, and that integer was later being referenced while being posted to the NotificationManager.
In between getting the integer reference and the pending intent going off, the app was updated and all of the drawable references changed. The integer that used to reference the correct drawable now referenced either the incorrect drawable or none at all (none at all - causing this crash)
Using VectorXml inside your notification has been known to cause this issue. Use png's
Don't use SVG on Kitkat!
I had the same issue every time when I wanted to show a notification on Kitkat. What caused the problem for me is that I have defined every icon in xml (from svg), the small icon and the action icon also. After I have replaced them with png-s the problem solved at my side.
My problem was that the icon I was using on
.setSmallIcon(R.drawable.ic_stat_push_notif)
wasn't generated accordingly. According to the official doc:
As described in Providing Density-Specific Icon Sets and Supporting
Multiple Screens, you should create separate icons for all generalized
screen densities, including low-, medium-, high-, and
extra-high-density screens. This ensures that your icons will display
properly across the range of devices on which your application can be
installed.
So the best way to fullfill the above, I used Notification Generator provided by Roman Nurik on https://romannurik.github.io/AndroidAssetStudio/index.html
In that way, you can use an image (taking into consideration that this has to have transparent background) and let the generator do the job for you generating the different sizes for notification icons.
The most important thing is that if the icon generator after you browse the image you are going to use shows you a white filled circle or square, there are problems with your image, maybe because it doesn't have any transparencies, so make sure that you has this ok.
android.app.RemoteServiceException: Bad notification posted
I had the same issue, but I was resolved. My problem is ".xml file" of Remote view.
In my xml file I was added one View in between the LinearLayout for divider.
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:id="#+id/view"
android:background="#000000" />
The above View component creating the Bad notification exception. This Exception reason is only xml file of Remoteviews.
After removing that View component, My code executed properly, without any exception. So I felt that Notification drawer not accepting any customized views.
So you don't draw any thing like the above view in the .xml file of RemoteView object.
In my app, this kind of bug happens only during upgrading. If the resource id changes in the newer version, Android RemoteView may fail to find the resource and throw out the RemoteServiceException. If you publish a 3rd version and do not change the resource id, the bugs may disappear only temporarily.
It is possible to reduce this kind of bugs by editing res/values/public.xml and res/values/ids.xml. Compiler will generate an individual resource id if the resource id is not in public.xml or ids.xml. When u change the resource name or add some new resources, the id may change and some devices may fail to find it.
So the step is as following:
Decompile the apk file and in res/values find the public.xml and ids.xml
Find all resources related to RemoteView in your app and copy them ( strings, dimen, drawable, layout, id, color... )
Create public.xml and ids.xml under res/values in your source code and paste the lines u just copied
Note:
Gradle 1.3.0 and above ignore the local public.xml. To make it work, u need to add some script in your build.gradle
afterEvaluate {
for (variant in android.applicationVariants) {
def scope = variant.getVariantData().getScope()
String mergeTaskName = scope.getMergeResourcesTask().name
def mergeTask = tasks.getByName(mergeTaskName)
mergeTask.doLast {
copy {
int i=0
from(android.sourceSets.main.res.srcDirs) {
include 'values/public.xml'
rename 'public.xml', (i == 0? "public.xml": "public_${i}.xml")
i++
}
into(mergeTask.outputDir)
}
}
}
}
Note:
This script does not support submodules project. I am trying to fix it.
In Android Studio version 3.0.0 and above, when adding a new image in the drawables folder choose drawable instead of drawable-v24.
If the image,you are using, is alread a (v24) just copy it and paste it in its same directory (eg. drawables). This time it will ask you which regular or v24 - just make sure its not the v24 and try it again this should fix the error.
Just in case the icon is not important, you can replace,
R.drawable.your_icon
To
android.R.drawable.some_standard_icon
This works!
I had RemoteServiceException when use Notification in my class extends from FirebaseMessagingService. I added the following code to AndroidManifest.xml:
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="#drawable/ic_small" />
Also resource ic_small set in instance of a class Notification.Builder by method setSmallIcon(int icon).
You have pass same icon
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="#drawable/ic_stat_name" />
and you notification
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_stat_name)
.setContentTitle("Title")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
If you have a notification visible while your app is updated, you might run into this. What you may need to do is create a BroadcastReceiver that waits for a PACKAGE_CHANGED message, at which point you shutdown all your services which will also dismiss their associated notifications.
<receiver android:name=".MyBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.PACKAGE_CHANGED" />
</intent-filter>
</receiver>
Same issue happened with me as well and I have solved the same
REASON: This is happening because of we are using vector drawable for RemoteViews and vector drawable generates drawable at compile-time. Also I am not sure why some devices are not able to detect the generated drawable resources id while we are upping the app. But yes this was the reason.
REPRODUCE
Steps
1. Install previous build.
2. Send a notification
3. Update the build with next version code
4. After updating the app don't open the app and send notification again
SOLUTION
Replace the vector drawable with normal drawable(.png or .jpg) file.
I hope this resolves the problem.
You can put that vector xml file in both drawable and drawable v24. Those android version less than or equal to Android 6 will pick it up from drawable folder, and and newer version above android 6 will pick it up from drawable v24.
Its not about the Image type (vector, png, etc.) but the folder to which you are referring
to.
For me the error caused was due to a device (Nougat) referring to an icon present in v26 folder.
Solution: Just add the relevant icon to the other folder as well and the issue will be gone.
I had the same issue when I set a notification in a bundle.
I tried this and it solved my problem:
builder.setLargeIcon(large_icon);
builder.setSmallIcon(R.drawable.small_icon);
Make sure that setLargeIcon() invoked before setSmallIcon().
I too had the same issue. The issue is with the icon which you are using, I was using android.R.drawable.stat_sys_download. Go to drawables.xml and paste this.
<resources>
<item name="ic_start_download" type="drawable">#android:drawable/stat_sys_download</item>
</resource>
and then in your code
builder.setSmallIcon(R.drawable.ic_start_download);
You can try some other image instead of this image
My way to solve this: I had "bad" views in my layout (ex: a checkbox) - so I removed them.
RemoteViews seem to support only images and texts (to be confirmed by reading the doc).
I had RemoteServiceException when use android.support.constraint.ConstraintLayout. Change it to LinearLayout or Relative
and also android:layout_height="wrap_content" for container
(this is not solution for current question but helps someone with similar core issue) I too had the same issue, But in my case I have used corrupted .png file which is causing same issue. So I have deleted it and re-included correct .png file.
Please replace <android.support.v7.widget.AppCompatTextView with <TextView from custom notification layout.
Because android.support.v7.widget.AppCompatTextView or android.support.v7.widget.AppCompatImageView only works at runtime.
So Use TextView or ImageView
If any one still facing this issue :
Add a png file in your drawable folder with name ic_stat_ic_notification (or any name u like )
and in your manifest add below couple of lines
and u can create your icons over here - >
https://romannurik.github.io/AndroidAssetStudio/icon
I got this error due to autolink and linksClickable options in textview in notification view:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:autoLink="all"
android:linksClickable="true"
android:text="#string/app_name"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#color/white" />
Be careful!
It was a problem of icon location. In my case the notification icon was in drawable-anydpi-v24, I simply copied the icon in drawable folder and the error has gone.
Got this error in my Flutter android app and checked to see that all the resources are present and named correctly but still not working, I was using resources from mipmap. I changed it to drawable and placed the notification icons inside drawble folders and fixed the issue, hoping it might help someone later on
Synchrinize the project and than Clean it,
File > Synchronize then : Build > Clean Project
I hope that will help you all, It's work for me
This worked for me. Comment the reference of the icon and thus be able to use the NotificationCompat.Builder without problems.
$msg_notificacion = [
'title' => "titulonotif",
// "icon" : "myicon",
'body' =>"cuerponotif"
];
I'd like to show a timestamp in an Android Notification, just like the Android Design Guidelines suggest. (see the first snapshot, "12:03PM" is what I want!).
I tried many different ways, I thought setWhen would do it, but it only seems to affect the ordering in the Notification tray. Any idea how to achieve that?
See my code below:
Notification.Builder builder = new Notification.Builder(context);
builder.setContentIntent(pendingIntent)
.setSmallIcon(R.drawable.ic_notify)
.setLargeIcon(largeIcon)
.setTicker(text)
.setNumber(unreadCount)
.setWhen((new Date()).getTime())
.setAutoCancel(true)
.setContentTitle(title)
.setContentText(text)
.setDefaults(Notification.DEFAULT_VIBRATE);
notificationManager.notify(NOTIFICATION_ID, builder.getNotification());
I don't want to use a custom layout for the notification.
I think I found the answer myself, when seems to be displayed only on Android 4.0.3 and later.
My wife's Nexus S (4.0.3) shows it, and I just upgraded to 4.0.4 on my Galaxy Nexus and it magically started to work!
It also shows on older versions (2.3 for instance), but not on 4.0.2 !
Use setContentInfo and pass your date as a string into it.
From this link
public Notification.Builder setContentInfo (CharSequence info) Since: API Level 11
Set the large text at the right-hand side of the notification.
Large Text at the right hand side of the notification should be where you want to put time.
Also from the same link:
public Notification.Builder setWhen (long when) Since: API Level 11
Set the time that the event occurred. Notifications in the panel are
sorted by this time.
which means that setWhen only sorts the notifications, and doesn't set any text.
