In my app, I am doing multiple upload requests using retrofit 2 and launching a new notification for each upload.
After going through a lot of similar questions, I am not sure how can I cancel the request using Call.cancel for a particular upload when its notification action cancel button clicked.
Thanks!
Define a Map object
Map<int,Call> callStack= new HashMap<>();
When called to your_call_object add this.
int notificationId = ((Double) (Math.random() * 10000)).intValue()
callStack.put(notificationId, your_call_object)
When you creating a notification object add that notificationId.
notificationManager.notify(notificationId, notification.build());
When clicked Cancel Button, find that notificationId and...
Call your_call_object = callStack.getObject(notificaitonId);
your_call_object.cancel();
please read this link. a very detail explanation is provided tailor it to your needs.https://futurestud.io/tutorials/retrofit-2-cancel-requests
try to connect your service notification with your activity or service upload with a broadcast, in your notification action cancel send the broadcaster:
//declare in your manifest your broadcast class
Intent intentBroadcast = new Intent();
intentBroadcast.setAction("CANCEL_RETROFIT_CALL");
intentBroadcast.putExtra("ID_CALL","upload_123");
LocalBroadcastManager.getInstance(this).sendBroadcast(intentBroadcast);
PendingIntent pendintAction = PendingIntent.getBroadcast(this, 0, intentBroadcast, PendingIntent.FLAG_UPDATE_CURRENT);
//then set the action setup
action = new NotificationCompat.Action.Builder(R.drawable.ic_action_cancel,
"cancel", pendintAction).build();
//launch your notification
NotificationCompat.Builder notificacion = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_noti_logo)
.setContentTitle(remoteMessage.getData().getAlert())
.setContentText(remoteMessage.getMessage())
.setAutoCancel(true)
.setSound(alarmSound)
.setContentIntent(pendingIntent)
.setVibrate(new long[]{1000, 1000})
.addAction(action);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificacion.build());
//in your actionbroadcast class
public class ActionBroadcast extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
LocalBroadcastManager broadcaster = LocalBroadcastManager.getInstance(context);
String accion = intent.getAction();
String id_call = intent.getStringExtra("ID_CALL");
if (accion.equals("CANCEL_RETROFIT_CALL")) {
switch (id_call) {
case callID:
intent = new Intent("CANCEL_RETROFIT_CALL");
intent.putExtra("id_call", id);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
break;
}
}
}
}
i hope that this conde can help u .. https://github.com/googlesamples/android-UniversalMusicPlayer
When my application is launched, it performs an API call and then schedules notifications based on the results. This amounts to around ~10 notifications being scheduled. There seems to be an issue with the timestamp displayed on the actual notification being incorrect.
Since I am creating these notifications and then scheduling an alarm with an AlarmManager, the default time present on the notification will be the time at which the notification is created (System.currentTimeMillis()).
I've tried to use the .setWhen() method on my Notification.Builder to set it to the time I am using to schedule the previously mentioned alarm. This is a little better, however, because notifications are not guaranteed to be delivered at the exact time specified, I often get notifications a few minutes in the past.
Additionally, I tried to manually override the when field on the notification in my BroadcastReceiver, right before .notify() is actually called:
public class NotificationPublisher extends BroadcastReceiver {
public static String NOTIFICATION_ID = "notification_id";
public static String NOTIFICATION = "notification";
public void onReceive(Context context, Intent intent) {
NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = intent.getParcelableExtra(NOTIFICATION);
notification.when = System.currentTimeMillis();
int id = intent.getIntExtra(NOTIFICATION_ID, 0);
notificationManager.notify(id, notification);
}
}
However, in the above scenario, it seems that .when is ignored.
Frankly, I am simply looking for a way to have the timestamp displayed on the notification be the time at which it is actually displayed.
I would suggest passing in your notification's information as extras then building the notification inside of the BroadcastReceiver. This will build the notification just before it is issued, so it will have the same time your AlarmManager triggers the BroadcastReceiver.
From wherever you're scheduling the notification:
private void scheduleNotification(){
// Create an intent to the broadcast receiver you will send the notification from
Intent notificationIntent = new Intent(this, SendNotification.class);
// Pass your extra information in
notificationIntent.putExtra("notification_extra", "any extra information to pass in");
int requestCode = 1;
// Create a pending intent to handle the broadcast intent
PendingIntent alarmIntent = PendingIntent
.getBroadcast(this, requestCode, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
// Set your notification's trigger time
Calendar alarmStart = Calendar.getInstance();
alarmStart.setTimeInMillis(System.currentTimeMillis());
alarmStart.set(Calendar.HOUR_OF_DAY, 6); // This example is set to approximately 6am
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
// Set the alarm with the pending intent
// be sure to use set, setExact, setRepeating, & setInexactRepeating
// as well as RTC_WAKEUP, ELAPSED_REALTIME_WAKEUP, etc.
// where appropriate
alarmManager.set(AlarmManager.RTC_WAKEUP, alarmStart.getTimeInMillis(), alarmIntent);
}
Then, inside your BroadcastReceiver's onReceive:
String notificationExtra = null;
// Retrieve your extra data
if(intent.hasExtra("notification_extra")){
notificationExtra = intent.getStringExtra("notification_extra");
}
//Build the notification
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
mBuilder.setSmallIcon(notificationIcon)
.setContentTitle(notificationTitle)
.setContentText(notificationMessage)
.setAutoCancel(true); // Use AutoCancel true to dismiss the notification when selected
// Check if notificationExtra has a value
if(notificationExtra != null){
// Use the value to build onto the notification
}
//Define the notification's action
Intent resultIntent = new Intent(context, MainActivity.class); // This example opens MainActivity when clicked
int requestCode = 0;
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
context,
requestCode,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
//Set notification's click behavior
mBuilder.setContentIntent(resultPendingIntent);
// Sets an ID for the notification
int mNotificationId = 1;
// Gets an instance of the NotificationManager service
NotificationManager mNotifyMgr =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// Builds the notification and issues it.
mNotifyMgr.notify(mNotificationId, mBuilder.build());
I have also been struggling with this for a bit, but your question actually brought me to the best answer. I checked out setWhen() and it seems like now this just works fine (checked with API lvl 30 & 31). As this post is a few years old, maybe this issue was fixed in the meantime. So here's how I did it in Kotlin:
class NotificationPublisher : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent) {
val notificationManager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val notification = intent.getParcelableExtra<Notification>(NOTIFICATION)
notification?.`when` = System.currentTimeMillis() // overwriting the creation time to show the current trigger time when the notification is shown
val postId = intent.getIntExtra(NOTIFICATION_ID, 0)
notificationManager.notify(postId, notification)
}
Your NotificationPublisher's onReceive() method will be invoked only when scheduled alarm triggers as specified time. When you crate a notification from onReceive() method, it will definitely show the current time. No need to require to use .when or .setWhen() method.
Try this one:
public class NotificationPublisher extends BroadcastReceiver {
public static String NOTIFICATION_ID = "notification_id";
public static String NOTIFICATION = "notification";
public void onReceive(Context context, Intent intent) {
int id = intent.getIntExtra(NOTIFICATION_ID, 0);
// Notification
Notification notification = new Notification.Builder(context)
.setContentTitle("This is notification title")
.setContentText("This is notification text")
.setSmallIcon(R.mipmap.ic_launcher).build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Notification Manager
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager .notify(id, notification);
}
}
If you want to redirect to an activity when click on Notification, then you can use PendingIntent and set it to your Notification.
public class NotificationPublisher extends BroadcastReceiver {
public static String NOTIFICATION_ID = "notification_id";
public static String NOTIFICATION = "notification";
public void onReceive(Context context, Intent intent) {
int id = intent.getIntExtra(NOTIFICATION_ID, 0);
Intent intent = new Intent(context, YourTargetActivity.class);
intent.putExtra("KEY_ID", id); // Pass extra values if needed
PendingIntent pI = PendingIntent.getActivity(context, id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
// Notification
Notification notification = new Notification.Builder(context)
.setContentTitle("This is notification title")
.setContentText("This is notification text")
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pI).build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Notification Manager
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager .notify(id, notification);
}
}
Hope this will help~
Notification setAutoCancel(true) doesn't work if clicking on Action
I have a notification with an action within it. When I tap on the notification it gets removed from the list. However, when I click on the Action it successfully completes the Action (namely makes a call), but when I return to the list of notifications, it remains there.
Relative code of the AlarmReceiver:
public class AlarmReceiver extends BroadcastReceiver {
Meeting meeting;
/**
* Handle received notifications about meetings that are going to start
*/
#Override
public void onReceive(Context context, Intent intent) {
// Get extras from the notification intent
Bundle extras = intent.getExtras();
this.meeting = extras.getParcelable("MeetingParcel");
// build notification pending intent to go to the details page when click on the body of the notification
Intent notificationIntent = new Intent(context, MeetingDetails.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
notificationIntent.putExtra("MeetingParcel", meeting); // send meeting that we received to the MeetingDetails class
notificationIntent.putExtra("notificationIntent", true); // flag to know where the details screen is opening from
PendingIntent pIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
// build intents for the call now button
Intent phoneCall = Call._callIntent(meeting);
if (phoneCall != null) {
PendingIntent phoneCallIntent = PendingIntent.getActivity(context, 0, phoneCall, PendingIntent.FLAG_CANCEL_CURRENT);
int flags = Notification.FLAG_AUTO_CANCEL;
// build notification object
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
Notification notification = builder.setContentTitle("Call In")
.setContentText(intent.getStringExtra("contextText"))
.setTicker("Call In Notification")
.setColor(ContextCompat.getColor(context, R.color.colorBluePrimary))
.setAutoCancel(true) // will remove notification from the status bar once is clicked
.setDefaults(Notification.DEFAULT_ALL) // Default vibration, default sound, default LED: requires VIBRATE permission
.setSmallIcon(R.drawable.icon_notifications)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(meeting.description))
.addAction(R.drawable.icon_device, "Call Now", phoneCallIntent)
.setCategory(Notification.CATEGORY_EVENT) // handle notification as a calendar event
.setPriority(Notification.PRIORITY_HIGH) // this will show the notification floating. Priority is high because it is a time sensitive notification
.setContentIntent(pIntent).build();
notification.flags = flags;
// tell the notification manager to notify the user with our custom notification
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notification);
}
}
}
use this flag:
Notification.FLAG_AUTO_CANCEL
inside this:
int flags = Notification.FLAG_AUTO_CANCEL;
Notification notification = builder.build();
notification.flags = flags;

Ok turns out it's a known problem already, and it needs extra code to be done (keeping reference to notification through id). Have no clue why API does not provide this, as it seems very logical to do. But anyways,
see this answer in stackoverflow:
When you called notify on the notification manager you gave it an id - that is the unique id you can use to access it later (this is from the notification manager:
notify(int id, Notification notification)
To cancel, you would call:
cancel(int id)
with the same id. So, basically, you need to keep track of the id or possibly put the id into a Bundle you add to the Intent inside the PendingIntent?
I faced this problem today, and found that FLAG_AUTO_CANCEL and setAutoCanel(true), both work when click on notification,
but not work for action click
so simply, in the target service or activity of action, cancel the notification
NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
manager.cancelAll();
or if have more notification
manager.cancel(notificationId);
You have created two pending intent use in boths and change Flag too.
PendingIntent pIntent = PendingIntent.getActivity(context, (int) System.currentTimeMillis(), notificationIntent, 0);
PendingIntent phoneCallIntent = PendingIntent.getActivity(context, (int) System.currentTimeMillis(), phoneCall, PendingIntent.FLAG_UPDATE_CURRENT);
// CHANGE TO THIS LINE
PendingIntent pIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
PendingIntent phoneCallIntent = PendingIntent.getActivity(context, 0, phoneCall, PendingIntent.FLAG_CANCEL_CURRENT);
My app plays music and when users open notifications screen by swiping from the top of the screen ( or generally from the bottom right of the screen on tablets ), I want to present them a button to stop the currently playing music and start it again if they want.
I am not planning to put a widget on the user's home screen, but just into notifications. How can I do this?
You can create an intent for the action (in this case stop playing) and then add it as an action button to your notification.
Intent snoozeIntent = new Intent(this, MyBroadcastReceiver.class);
snoozeIntent.setAction(ACTION_SNOOZE);
snoozeIntent.putExtra(EXTRA_NOTIFICATION_ID, 0);
PendingIntent snoozePendingIntent =
PendingIntent.getBroadcast(this, 0, snoozeIntent, 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Hello World!")
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setContentIntent(pendingIntent)
.addAction(R.drawable.ic_snooze, getString(R.string.snooze),
snoozePendingIntent);
Please refer to the Android documentation.
I will try to provide a solution that I have used and most of the music player also use the same technique to show player controls in notification bar.
I am running a service which is used to manage Media Player and all its controls. Activity User control interacts with Service by sending Intents to the service for example
Intent i = new Intent(MainActivity.this, MyRadioService.class);
i.setAction(Constants.Player.ACTION_PAUSE);
startService(i);
TO receive intents and perform action in Service class I am using following code in onStartCommand method of Service
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (intent.getAction().equals(Constants.Player.ACTION_PAUSE)) {
if(mediaPlayer.isPlaying()) {
pauseAudio();
}
}
Now to exact answer to your question to show notification with playing controls. You can call following methods to show notification with controls.
// showNotification
private void startAppInForeground() {
// Start Service in Foreground
// Using RemoteViews to bind custom layouts into Notification
RemoteViews views = new RemoteViews(getPackageName(),
R.layout.notification_status_bar);
// Define play control intent
Intent playIntent = new Intent(this, MyRadioService.class);
playIntent.setAction(Constants.Player.ACTION_PLAY);
// Use the above play intent to set into PendingIntent
PendingIntent pplayIntent = PendingIntent.getService(this, 0,
playIntent, 0);
// binding play button from layout to pending play intent defined above
views.setOnClickPendingIntent(R.id.status_bar_play, pplayIntent);
views.setImageViewResource(R.id.status_bar_play,
R.drawable.status_bg);
Notification status = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
status = new Notification.Builder(this).build();
}
status.flags = Notification.FLAG_ONGOING_EVENT;
status.icon = R.mipmap.ic_launcher;
status.contentIntent = pendingIntent;
startForeground(Constants.FOREGROUND_SERVICE, status);
}
Hope this really helps you. And you will be able to achieve what you want. Have a Happy Coding :)
// It shows buttons on lock screen (notification).

tested, working code with android Pie. These all go inside the same service class.
Show a notification:
public void setNotification() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
NotificationChannel channel = new NotificationChannel("a", "status", NotificationManager.IMPORTANCE_DEFAULT);
channel.setDescription("notifications");
notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
else
notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Receiver.service = this;
Notification.MediaStyle style = new Notification.MediaStyle();
notification = new Notification.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Notification")
.addAction(R.drawable.close_icon, "quit_action", makePendingIntent("quit_action"))
.setStyle(style);
style.setShowActionsInCompactView(0);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
notification.setChannelId("a");
}
// notificationManager.notify(123 , notification.build()); // pre-oreo
startForeground(126, notification.getNotification());
}
Helper function:
public PendingIntent makePendingIntent(String name)
{
Intent intent = new Intent(this, FloatingViewService.Receiver.class);
intent.setAction(name);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
return pendingIntent;
}
To handle the actions:
static public class Receiver extends BroadcastReceiver {
static FloatingViewService service;
#Override
public void onReceive(Context context, Intent intent)
{
String whichAction = intent.getAction();
switch (whichAction)
{
case "quit_action":
service.stopForeground(true);
service.stopSelf();
return;
}
}
}
You'll need to update your manifest too:
<receiver android:name=".FloatingViewService$Receiver">
<intent-filter>
<action android:name="quit_action" />
</intent-filter>
</receiver>
I think that beside Ankit Gupta answer, you can use MediaSession (API > 21) to add native mediaController view :
notificationBuilder
.setStyle(new Notification.MediaStyle()
.setShowActionsInCompactView(new int[]{playPauseButtonPosition}) // show only play/pause in compact view
.setMediaSession(mSessionToken))
.setColor(mNotificationColor)
.setSmallIcon(R.drawable.ic_notification)
.setVisibility(Notification.VISIBILITY_PUBLIC)
.setUsesChronometer(true)
.setContentIntent(createContentIntent(description)) // Create an intent that would open the UI when user clicks the notification
.setContentTitle(description.getTitle())
.setContentText(description.getSubtitle())
.setLargeIcon(art);
Source: tutorial
you can alse create custom view and display it in the notificcation area , first answer here is great.
you can add button as below and can perform action on that button also i have done for me as below please check.
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_logo)
.setAutoCancel(true)
.setContentTitle(name)
.setContentText(body)
.setGroupSummary(true)
.addAction(android.R.drawable.ic_menu_directions, "Mark as read", morePendingIntent);
//morePendingIntent(do your stuff)
PendingIntent morePendingIntent = PendingIntent.getBroadcast(
this,
REQUEST_CODE_MORE,
new Intent(this, NotificationReceiver.class)
.putExtra(KEY_INTENT_MORE, REQUEST_CODE_MORE)
.putExtra("bundle", object.toString()),
PendingIntent.FLAG_UPDATE_CURRENT
);
I don't know if this is the right way or not, but it works.
Create a BroadCastReceiver class to receive the data when button is pressed.
public class MyBroadCastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String log = "URI: " + intent.toUri(Intent.URI_INTENT_SCHEME);
Log.d("my", "LOG:::::::" + log);
}
}
Now in any activity where you want to create the notification -
Intent intent = new Intent();
intent.setAction("unique_id");
intent.putExtra("key", "any data you want to send when button is pressed");
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, REQUEST_CODE, intent, 0);
Now use this pending intent when you are creating the notification and lastly you need to register this broadcast in order to receive it in MyBroadCastReceiver class.
BroadcastReceiver br = new MyBroadCastReceiver();
IntentFilter filter = new IntentFilter("unique_id");
registerReceiver(br, filter);
Now if you want to do certain things when the button is pressed, you can do so in the onReceive() method in MyBroadCastReceiver class.
Since API level 16 (Jelly Bean), there is the possibility to add actions to a notification with
builder.addAction(iconId, title, intent);
But when I add an action to a notification and the action is pressed, the notification is not going to be dismissed.
When the notification itself is being clicked, it can be dismissed with
notification.flags = Notification.FLAG_AUTO_CANCEL;
or
builder.setAutoCancel(true);
But obviously, this has nothing to with the actions associated to the notification.
Any hints? Or is this not part of the API yet? I did not find anything.
When you called notify on the notification manager you gave it an id - that is the unique id you can use to access it later (this is from the notification manager:
notify(int id, Notification notification)
To cancel, you would call:
cancel(int id)
with the same id. So, basically, you need to keep track of the id or possibly put the id into a Bundle you add to the Intent inside the PendingIntent?
Found this to be an issue when using Lollipop's Heads Up Display notification. See design guidelines. Here's the complete(ish) code to implement.
Until now, having a 'Dismiss' button was less important, but now it's more in your face.
Building the Notification
int notificationId = new Random().nextInt(); // just use a counter in some util class...
PendingIntent dismissIntent = NotificationActivity.getDismissIntent(notificationId, context);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setPriority(NotificationCompat.PRIORITY_MAX) //HIGH, MAX, FULL_SCREEN and setDefaults(Notification.DEFAULT_ALL) will make it a Heads Up Display Style
.setDefaults(Notification.DEFAULT_ALL) // also requires VIBRATE permission
.setSmallIcon(R.drawable.ic_action_refresh) // Required!
.setContentTitle("Message from test")
.setContentText("message")
.setAutoCancel(true)
.addAction(R.drawable.ic_action_cancel, "Dismiss", dismissIntent)
.addAction(R.drawable.ic_action_boom, "Action!", someOtherPendingIntent);
// Gets an instance of the NotificationManager service
NotificationManager notifyMgr = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// Builds the notification and issues it.
notifyMgr.notify(notificationId, builder.build());
NotificationActivity
public class NotificationActivity extends Activity {
public static final String NOTIFICATION_ID = "NOTIFICATION_ID";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.cancel(getIntent().getIntExtra(NOTIFICATION_ID, -1));
finish(); // since finish() is called in onCreate(), onDestroy() will be called immediately
}
public static PendingIntent getDismissIntent(int notificationId, Context context) {
Intent intent = new Intent(context, NotificationActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.putExtra(NOTIFICATION_ID, notificationId);
PendingIntent dismissIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
return dismissIntent;
}
}
AndroidManifest.xml (attributes required to prevent SystemUI from focusing to a back stack)
<activity
android:name=".NotificationActivity"
android:taskAffinity=""
android:excludeFromRecents="true">
</activity>
I found that when you use the action buttons in expanded notifications, you have to write extra code and you are more constrained.
You have to manually cancel your notification when the user clicks an action button. The notification is only cancelled automatically for the default action.
Also if you start a broadcast receiver from the button, the notification drawer doesn't close.
I ended up creating a new NotificationActivity to address these issues. This intermediary activity without any UI cancels the notification and then starts the activity I really wanted to start from the notification.
I've posted sample code in a related post Clicking Android Notification Actions does not close Notification drawer.
In new APIs don't forget about TAG:
notify(String tag, int id, Notification notification)
and correspondingly
cancel(String tag, int id)
instead of:
cancel(int id)
https://developer.android.com/reference/android/app/NotificationManager
In my opinion using a BroadcastReceiver is a cleaner way to cancel a Notification:
In AndroidManifest.xml:
<receiver
android:name=.NotificationCancelReceiver" >
<intent-filter android:priority="999" >
<action android:name="com.example.cancel" />
</intent-filter>
</receiver>
In java File:
Intent cancel = new Intent("com.example.cancel");
PendingIntent cancelP = PendingIntent.getBroadcast(context, 0, cancel, PendingIntent.FLAG_CANCEL_CURRENT);
NotificationCompat.Action actions[] = new NotificationCompat.Action[1];
NotificationCancelReceiver
public class NotificationCancelReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
//Cancel your ongoing Notification
};
}
You will need to run the following code after your intent is fired to remove the notification.
NotificationManagerCompat.from(this).cancel(null, notificationId);
NB: notificationId is the same id passed to run your notification
You can always cancel() the Notification from whatever is being invoked by the action (e.g., in onCreate() of the activity tied to the PendingIntent you supply to addAction()).
Just put this line :
builder.setAutoCancel(true);
And the full code is :
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(android.R.drawable.ic_dialog_alert);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.google.co.in/"));
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
builder.setContentIntent(pendingIntent);
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.misti_ic));
builder.setContentTitle("Notifications Title");
builder.setContentText("Your notification content here.");
builder.setSubText("Tap to view the website.");
Toast.makeText(getApplicationContext(), "The notification has been created!!", Toast.LENGTH_LONG).show();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
builder.setAutoCancel(true);
// Will display the notification in the notification bar
notificationManager.notify(1, builder.build());
Just for conclusion:
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
Intent intent = new Intent(context, MyNotificationReceiver.class);
intent.putExtra("Notification_ID", 2022);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
context,
0,
intent,
...);
Notification notification = new NotificationCompat.Builder(...)
...
.addAction(0, "Button", pendingIntent)
.build();
notificationManager.notify(2022, notification);
and for dismiss the notification, you have two options:
approach 1: (in MyNotificationReceiver)
NotificationManager manager = (NotificationManager)
context.getSystemService(NOTIFICATION_SERVICE);
manager.cancel(intent.getIntExtra("Notification_ID", -1));
approach 2: (in MyNotificationReceiver)
NotificationManagerCompat manager = NotificationManagerCompat.from(context);
manager.cancel(intent.getIntExtra("Notification_ID", -1));
and finally in manifest:
<receiver android:name=".MyNotificationReceiver" />
builder.setAutoCancel(true);
Tested on Android 9 also.
