I want to trigger a Toast if the user come from a Notification click.
But I don't know how to know if a user is coming from a notification click.
Right know I set the notification like that:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel =
new NotificationChannel(notification_channel, notification_channel, importance);
String description = "A channel which shows notifications about the app";
channel.setDescription(description);
channel.setLightColor(Color.MAGENTA);
NotificationManager notificationManager = (NotificationManager) getApplicationContext().
getSystemService(Context.NOTIFICATION_SERVICE);
if (notificationManager != null) {
notificationManager.createNotificationChannel(channel);
}
}
String notificationTitle = "Title";
String notificationText = "Notification Text";
Intent intent_not = new Intent(getApplicationContext(), Home_Base.class);
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 1, intent_not, FLAG_UPDATE_CURRENT);
//build the notification
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(getApplicationContext(), notification_channel)
.setSmallIcon(R.drawable.fiamma)
.setContentTitle(notificationTitle)
.setContentText(notificationText)
.setAutoCancel(true)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setContentIntent(pendingIntent);
//trigger the notification
NotificationManagerCompat notificationManager =
NotificationManagerCompat.from(getApplicationContext());
notificationManager.notify(123, notificationBuilder.build());
Try setting action (say, On_NOTIFICATION_CLICK) using intent_not.setAction()
In Home_Base using getIntent().getAction(), try to get the action from the intent received.
If the action received in Home_Base is On_NOTIFICATION_CLICK then its a notification Click action.

I have been trying to create an incoming call type notification for my Android app, written in native Java code, and in many resources online I have read that using the .setOngoing(true) tag on the NotificationBuilder would be enough to have the desired behaviour of the notification being visible, playing the ringtone sound until it is clicked, but that has not worked for me.
I have also tried using the flags Notification.FLAG_INSISTENT and Notification.FLAG_NO_CLEAR without success.
Here is my current code:
private void ringtone(Context context){
String channelId = "call_channel";
Intent notificationIntent = new Intent(context, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_IMMUTABLE);
Uri ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context, channelId)
.setSmallIcon(R.drawable.ic_launcher_background)
.setContentTitle("Incoming Call")
.setContentText("You have an incoming call")
.setCategory(Notification.CATEGORY_CALL)
.setOngoing(true)
.setAutoCancel(true)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setContentIntent(contentIntent);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence channelName = "Incoming Calls";
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel notificationChannel = new NotificationChannel(channelId, channelName, importance);
notificationChannel.enableVibration(true);
long[] pattern = {0, 1000, 500, 1000};
notificationChannel.setVibrationPattern(pattern);
AudioAttributes att = new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_NOTIFICATION_RINGTONE)
.setLegacyStreamType(AudioManager.STREAM_RING)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
notificationChannel.setAllowBubbles(true);
}
notificationChannel.setLockscreenVisibility(NotificationCompat.VISIBILITY_PUBLIC);
notificationChannel.setSound(ringtoneUri,att);
notificationManager.createNotificationChannel(notificationChannel);
}else{
notificationBuilder.setSound(ringtoneUri);
}
Notification notification = notificationBuilder.build();
notification.flags |= Notification.FLAG_INSISTENT | Notification.FLAG_NO_CLEAR;
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notification);
}
My intention is to have an incoming call type of notification much like other applications such as MS Teams, Whatsapp, ETC. and my issue is that the notification gets minimized after showing on screen for a few seconds, and the ringtone stops shortly after. Thank you for any help with this.
I have typed the following function to get notifications in android.
But I get an error which says Failed to post notification on channel "null". I know that I'm missing some piece of code which seems to be inserted for devices running on some newer versions.
Can I get the exact code to be inserted?
void create_notification(String string){
Intent intent = new Intent(this, MainActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(intent);
PendingIntent pendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT
);
Notification notification = new Notification.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(getString(R.string.app_name))
.setAutoCancel(true)
.setPriority(Notification.PRIORITY_MAX)
.setDefaults(Notification.DEFAULT_VIBRATE)
.setContentIntent(pendingIntent)
.setContentText(string)
.build();
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(NOTIFICATION_ID, notification);
}
In your builder, you can add the channelID, for example:
Notification notification = new Notification.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(getString(R.string.app_name))
.setAutoCancel(true)
.setChannelId("base_channel") //<-- set the name you feel is proper to your project
.setPriority(Notification.PRIORITY_MAX)
.setDefaults(Notification.DEFAULT_VIBRATE)
.setContentIntent(pendingIntent)
.setContentText(string)
.build();
The documentation (first result on google for the search terms "android notification channel") gives the following example:
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);
}
}
And then on your notification you need to specify the channel ID:
Notification notification = new Notification.Builder(this, CHANNEL_ID)
...
Have you tried this?
I'm currently trying to implement a push notification into my app, that will be sent as soon as there's an internet connection. The service for checking the connection works just fine and the showNotifications() Method is being called. But the Notification won't show up in the bar. This is the code:
private void showNotifications(){
Intent intent = new Intent(APITest2.this, Start.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("notif","notify");
PendingIntent contentIntent = PendingIntent.getActivity(APITest2.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder= new NotificationCompat.Builder(APITest2.this)
.setSmallIcon(R.drawable.ic_android)
.setContentTitle("Title")
.setContentText("Text")
.setAutoCancel(true);
builder.setContentIntent(contentIntent);
NotificationManager notificationManager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0,builder.build());
}
Am I missing something?
Thanks in advance for any help!
Use notification manager like below to support all android versions
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
builder.setChannelId("com.package.name");
NotificationChannel channel = new NotificationChannel(
"com.package.name",
"AppName",
NotificationManager.IMPORTANCE_HIGH
);
if (notificationManager != null) {
notificationManager.createNotificationChannel(channel);
}
}
notificationManager.notify(0, builder.build());
Create channel as like below,
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.setUsage(AudioAttributes.USAGE_NOTIFICATION)
.build();
String characterSequence = "Message Alert";
NotificationChannel channel = new NotificationChannel(channelId,
characterSequence,NotificationManager.IMPORTANCE_DEFAULT);
channel.setSound(soundUri,audioAttributes );
NotificationManager manager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
manager.createNotificationChannel(channel);
}
You need to pass channel id here like below,
NotificationCompat.Builder builder= new NotificationCompat.Builder(APITest2.this,channelId)
Also refer https://developer.android.com/training/notify-user/channels
If you need to show heads up notification, then you need to set Importance level in Notification Channel as IMPORTANCE_HIGH. And need to set priority in notification builder as below.
setPriority(NotificationCompat.PRIORITY_HIGH);
I'm developing a stopwatch that can show three notifications. When i update the notifications (every second), all of them are heading up in the notification bar, switching between them.
Is there any way to prevent them from moving to the top every time they are updated?
With the following code I create notifications from different services, each one with unique CHANNEL_ID and NOTIFY_ID.
private void createNotificationChannel() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel serviceChannel = new NotificationChannel(
CHANNEL_ID,getResources().getText(R.string.stopwatch_channel),
NotificationManager.IMPORTANCE_LOW
);
NotificationManager manager = getSystemService(NotificationManager.class);
manager.createNotificationChannel(serviceChannel);
}
}
private Notification sendNotification(){
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this,
0, notificationIntent, 0);
Notification notification = new NotificationCompat.Builder(this, CHANNEL_ID)
.setContentTitle(getResources().getText(R.string.stopwatch)+" ยท "+String.format("%02d:%02d:%02d",hour,min,secs))
.setSmallIcon(R.drawable.ic_stopwatch_24dp)
.setContentIntent(pendingIntent)
.setShowWhen(false)
.build();
return notification;
}
private void updateNotification() {
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(NOTIFY_ID, sendNotification());
}
I want a notification on button press, the button press works fine because the toast "ITS OKAY!" is showing, but the notification does not appear. I just found a warning in logcat when the button is pressed:
W/libEGL: EGLNativeWindowType 0x75cc082010 disconnect failed
I know I must use CHANNEL_ID, but it's not better.
public void sendNotification() {
Toast.makeText(this, "ITS OKAY!", Toast.LENGTH_SHORT).show();
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this, "CHANNEL_ID")
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("It is my notification's Title!")
.setContentText("Notification Body!");
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, mBuilder.build());
}
I want a notification but my code only shows the toast
As it was said you have to create a notification channel for versions newer than Android O. As it is said in the docs, you can do it 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);
}
}
