On Notification Click put my app to background

I am working on an functionality where I get notification for POI (Point of Interest )while the user is navigating through Google Navigation app (used background service to get location update ).
scenario
1) User clicks navigate button from my app
2) He is taken to Google Navigation with data to navigate
3) Now user receives Notification for POI , then he clicks on it and he is taken to my app (my app brought to foreground , still Google Navigation i in background)
4) Now user is seeing my app , now he clicks the same notification , In this case I must put my app to background , so that use now sees Google Navigation
what i tried
Bringing my app to foreground is achieved , but putting my app to background on Notification click is not achieved .
moveTaskToBack(true) this is what I came across, but how can I implement this in Notification click
code
Intent intent = new Intent();
intent.setComponent(new ComponentName(getPackageName(), B_Activity.class.getName()));
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.putExtra("toFront", toFront);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

moveTaskToBack(boolean bool) is a method Of Activity class . So you can only call it with activity reference. I don't thing that there is way to do it with intent . What you can do send a broadcast in notification intent, and then validate the intent in activity if its in foreground -> call movetaskBack().
If your B_Activity has no Ui . Then just set null component in Pending Intent.
Use Local Broadcast to notify your currently running activity to call moveTaskToBack().
Intent intent = new Intent();
intent.setAction("com.settaskback");//Your custom action goes here
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
Then send broadcast on notification click. The activity which will receive this broadcast will put task to background (only if its in forground)
final Intent broadcastIntent = new Intent("com.settaskback");
PendingIntent intent = PendingIntent.getBroadcast(getApplicationContext(), 0, broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notificationBuilder.setContentIntent(intent);
notification = notificationBuilder.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, notification);
You need to register a Local broadcast receiver for this action in Activity.
#Override
public void onReceive(Context context, Intent intent) {
if(somecondition){
moveTaskToBack(true);
}
}

Updating multiple local notifications with SQL

Hello currently I have setup a application which allows the user to set an alarm. When this alarms reaches it designated time it will then send a notification to the user. Now currently each time this notification is activated it sends a static message e.g. "You have a notification". I want to be able to change this notifications title to the alarms name which I have stored inside of SQLOPENHELPER when the user made the alarm.
I have also given each alarm a specific ID which is the current time in milliseconds and then also stored this inside of my SQL. Now I know you require a new ID for each notification but how would I do this and relate it back to my SQL?
I have included a small diagram just to clarify what I'm doing and my current alarm and broadcast receiver...
Diagram................
Set alarm.....
// id - relates to the custom id given to that alarm
// receiver - is our intent
pendingIntent = PendingIntent.getBroadcast(v.getContext(), id, receiver, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.RTC_WAKEUP, myCalendar.getTimeInMillis(), pendingIntent);
// Intent array list is used to store multiple alarms
intentArrayList.add(pendingIntent);
Broadcast receiver...
NotificationManager notificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
Intent moveActivity = new Intent(context, AlarmActivity.class);
moveActivity.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// Works with moveActivity to move the user back to main application.
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, moveActivity, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
.setContentIntent(pendingIntent)
.setContentTitle("title")
.setContentText("text")
.setSmallIcon(R.mipmap.ic_launcher)
.setAutoCancel(true);
notificationManager.notify(0, builder.build());
// Notification ID has been left at 0 because I don't know what to do as this point and after trying to figure it out for 2 days I thought I should ask.
//// UPDATE
Main Activity
I have implemented a put extra just under my intent Array List
receiver.putExtra("title", id);
Broadcast
Bundle bundle = intent.getExtras();
if (bundle != null) {
pass = bundle.getString("title");
//I have put my notification in this section
}
I tested it by putting "pass" which is the String for retrieving the put extra into the title of my notification and it comes up blank?

Update your receiver intent as below to pass the ALARM_ID:
Intent receiver = new Intent(getApplicationContext(), Receiver.class);
receiver.putExtra("KEY_ALARM_ID", ALARM_ID); // ALARM_ID = id
In PendingIntent.getBroadcast(), Use ALARM_ID as requestCode.
PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext, ALARM_ID, receiver, PendingIntent.FLAG_UPDATE_CURRENT );
Always use different requestCode for different notification to get
correct result.
In notify() method, use ALARM_ID as id:
notificationManager.notify(ALARM_ID, builder.build());
Notification id should be unique within your application. If a
notification with the same id has already been posted by your
application and has not yet been canceled, it will be replaced by the
updated information.
In your BroadcastReceiver class onReceive() method get the ALARM_ID:
#Override
public void onReceive(Context context, Intent intent)
{
int alarmId= intent.getExtras().getInt("KEY_ALARM_ID");
// Do something with alarmId
}
Hope this will solve your problem.

// Main activity
receiver.putExtra("title", id);
pendingIntent = PendingIntent.getBroadcast(v.getContext(), id, receiver, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.RTC_WAKEUP, myCalendar.getTimeInMillis(), pendingIntent);
intentArrayList.add(pendingIntent);
Broadcast
Bundle bundle = intent.getExtras();
int pass = bundle.getInt("title" , 1);
Thanks psKink you gave me the kick I needed

onclicklistener for notification [duplicate]

This question already has answers here:
How to set click listener for notification?
(3 answers)
Closed 9 years ago.
I had set a notification in my app. Its working fine. If i click the notification in statusbar it takes to my app.
Now i need to set some work if the notification is clicked where can i set this?
Is there any method that implicitly got invoked when a notification is clicked?
Also i want to remove that notification if it is clicked,how to do so?
this is my code
notifManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Intent inty=getIntent();
note = new Notification(R.drawable.icon, "New E-mail", System.currentTimeMillis());
PendingIntent intent = PendingIntent.getActivity(MainActivity.this, 0, inty, 0);
note.setLatestEventInfo(MainActivity.this, "New E-mail", "You have one unread message.", intent);
notifManager.notify(R.string.search_hint, note);

You could add some extra data to the intent and then in your activity look for it in the onCreate and onNewIntent methods.
For example:
inty.putExtra("came from notification", true);
You can then read that out via the intent passed to onNewIntent or in onCreate by using getIntent().
intent.getBooleanExtra("came from notification", false);

Try to call broadcastReceiver it may helpful for your requirement,
Intent notificationIntent = new Intent(this, dummy_activity.class);
notificationIntent.setAction("android.intent.action.MAIN");
notificationIntent.addCategory("android.intent.category.LAUNCHER");
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT |
Notification.FLAG_AUTO_CANCEL);
// Now, once this dummy activity starts send a broad cast to your parent activity and finish the pending activity
//remember you need to register your broadcast action here to receive.
BroadcastReceiver call_method = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action_name = intent.getAction();
if (action_name.equals("call_method")) {
// call your method here and do what ever you want.
}
}
};
registerReceiver(call_method, new IntentFilter("call_method"));

Implement setOnClickPendingIntent from notification

I build custom notification that contain button and i want to listin when user press on it.
The button should not open any activity but only logic staff like change song.
the Code:
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.notification);
contentView.setTextViewText(R.id.toptext, nowPlayingTitle);
//this not work
Intent intent = new Intent(this, receiver.class);
intent.putExtra("UNIQ", "1");
PendingIntent pendingIntent = PendingIntent.getBroadcast(
this.getApplicationContext(), 234324243, intent, PendingIntent.FLAG_CANCEL_CURRENT)
contentView.setOnClickPendingIntent(R.id.imageButtonPlay,
pendingIntent);
notification.contentView = contentView;
// this is to return to my activity if click somwhere else in notification
Intent notificationIntent = new Intent(this, MYACTIVITY.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.contentIntent = contentIntent;
mNotificationManager.notify(NOTIFICATION_ID, notification);
I don't get the hang of the setOnClickPendingIntent what need to be in the second param?
How can i just call a function after user press on the button?
im probably missing something cause i dont understand the receiver side and what happend after user press

You are missing the fact that the button you created actually doesn't belong to your application. It is created in another context, in another process. There is no way it can call your function.
Instead, when the user taps the button, that pending intent is fired. You can catch it by your receiver (in your activity), check some parameters and do the action.
Or you can implement a service and handle this intent in background. I'd prefer this way.

thanks for quick answer. I try using receiver but it never fired.
The code is in the main question and i created for the reciever class the following code:
public class receiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
Bundle bundle = intent.getExtras();
}
}
but click on the notification never fire the receiver ( Test on debug mode )

How to detect if a notification has been dismissed?

Is there any way in Android to detect when a user swipes a notification to the left and deletes it? I'm using an alarmmanager to set a repeating alert and I need my repeating alert to stop when the notification is cancelled by the user. Here's my code:
Setting the repeating alert:
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), repeatFrequency, displayIntent);
My notification code:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Get the notification ID.
int notifID = getIntent().getExtras().getInt("Reminder_Primary_Key");
//Get the name of the reminder.
String reminderName = getIntent().getExtras().getString("Reminder_Name");
//PendingIntent stores the Activity that should be launched when the user taps the notification.
Intent i = new Intent(this, ViewLocalRemindersDetail.class);
i.putExtra("NotifID", notifID);
i.putExtra("notification_tap", true);
//Add FLAG_ACTIVITY_NEW_TASK to stop the intent from being launched when the notification is triggered.
PendingIntent displayIntent = PendingIntent.getActivity(this, notifID, i, Intent.FLAG_ACTIVITY_NEW_TASK);
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notif = new Notification(R.drawable.flag_red_large, reminderName, System.currentTimeMillis());
CharSequence from = "Here's your reminder:";
CharSequence message = reminderName;
notif.setLatestEventInfo(this, from, message, displayIntent);
//Pause for 100ms, vibrate for 250ms, pause for 100ms, and vibrate for 500ms.
notif.defaults |= Notification.DEFAULT_SOUND;
notif.vibrate = new long[] { 100, 250, 100, 500 };
nm.notify(notifID, notif);
//Destroy the activity/notification.
finish();
}
I know I need to call alarmManager.cancel(displayIntent) in order to cancel my repeating alarm. However, I don't understand where to put this code. I need to cancel the repeating alert ONLY when the user has tapped on the notification or dismissed it. Thanks for your help!

I believe that Notification.deleteIntent is what you are looking for. The doc says:
The intent to execute when the notification is explicitly dismissed by the user, either with the "Clear All" button or by swiping it away individually. This probably shouldn't be launching an activity since several of those will be sent at the same time.

To all those future people out there -- you can register a broadcast receiver to listen for notification delete inents.
Create a new broadcast receiver:
public class NotificationBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action == null || !action.equals(Config.NotificationDeleteAction)) {
return;
}
// Do some sweet stuff
int x = 1;
}
}
Register the broadcast receiver within your application class:
"If your app targets API level 26 or higher, you cannot use the manifest to declare a receiver for most implicit broadcasts (broadcasts that do not target your app specifically)."
Android Documentation.
registerReceiver(
new NotificationBroadcastReceiver(),
new IntentFilter(Config.NotificationDeleteAction)
);
You probably noticed the static variable Config.NotificationDeleteAction. This is a unique string identifier for your notification. It typically follows the following {namespace}{actionName} convention:
you.application.namespace.NOTIFICATION_DELETE
Set the delete intent on your notification builder:
notificationBuilder
...
.setDeleteIntent(createDeleteIntent())
...
Where, createDeleteIntent is the following method:
private PendingIntent createDeleteIntent() {
Intent intent = new Intent();
intent.setAction(Config.NotificationDeleteAction);
return PendingIntent.getBroadcast(
context,
0,
intent,
PendingIntent.FLAG_ONE_SHOT
);
}
Your registered broadcast receiver should receive the intent when your notification is dismissed.

You can also use an Activity PendingIntent, which may be simpler to implement if you have an Activity that can handle the dismissal, because you don't have to create and configure a broadcast receiver.
public static final String DELETE_TAG = "DELETE_TAG";
private PendingIntent createDeleteIntent(Context context) {
Intent intent = new Intent(context, MyActivity.class);
intent.putExtra(DELETE_TAG, true);
return PendingIntent.getActivity(
context,
0,
intent,
PendingIntent.FLAG_ONE_SHOT
);
}
MyActivity would receive the intent in its onCreate(), and in this example, could look for the DELETE_TAG extra to recognize it.
