How to Use Notification Delete Intent and Save Notification Details If Notification Not Clicked

I'm Using FCM and i Know How to Open Particular Activity When User Clicks it. My Problem is that, i wanna Save the Notification Details If the User Not Opened It.
I Found Something Like Delete Intent But I Can't Understand it ,Can anyone tell How Can I achieve this?

Where here you can do something like this.
On notification broadcast store first of all store notification data into you db and put this inserted record id in Pending intent Extras.
Now while user click on notification at that time you will receive this id in your particular activity from intent extras. get that id from intent extras and delete that recode from your db.
In case user in not click in notification at that time your notification is there in your db.
If you want to use DeleteIntent() then in that case you need to code like this.
notificationBuilder.setDeleteIntent(getDeleteIntent());
this line will call getDeleteIntent() while user clear notification.
this getDeleteIntent() method will be like this.
protected PendingIntent getDeleteIntent()
{
Intent intent = new Intent(mContext, NotificationBroadcastReceiver.class);
intent.setAction("notification_cancelled");
return PendingIntent.getBroadcast(mContext, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
}
This method will send one more broadcast with action name "notification_cancelled". you will receive this broadcast and check the action name will be same at that time you will get that deleted intent data.
#Override
public void onReceive(Context context, Intent intent)
{
String action = intent.getAction();
if(action.equals("notification_cancelled"))
{
// your code
}
}
Now if you want to store notification data then also pass data to the delete broadcast and receive this data from receiver intent and store in your db.

You can use delete intent like this
Intent intent = new Intent(context, SomeBroadcast.class);
NotificationCompat.Builder summaryBuilder = new
NotificationCompat.Builder(context, CHANNEL_ID)
.setContentTitle("Title")
.setContentText("")
.setAutoCancel(true)
.setDeleteIntent(PendingIntent.getBroadcast(context, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT));

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);
}
}

BroadcastReceiver does not react on notifications created in GmcService

Using Xamarin.Android.
I have a BroadcastReceiver:
public class MyBroadcastReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
try
{
string someExtra = intent.Extras.GetString("someExtra", string.Empty);
}
catch (Exception)
{
}
}
}
I use a Google Cloud Messaging Service and create a notification when receive some message. Using a notification builder's SetContentIntent I export some extras to the activity that will operate this notification if user opens it. And it works. But when I initialize my notification builder with SetDeleteIntent inside the GCM Service, the notification does not trigger OnReceive in the BroadcastReceiver if user swipe to dismiss the notification.
When I do all the same inside my activity (not inside the GCM service) OnReceive is triggered on every notification's swipe-to-dismiss event. But it does not work inside the service.
I have even implemented the same CreateNotification method in my activity as in the service. When I call it (to create the notification) from my activity - all works perfect. When I call it from the service using a static pointer to the current instance of the activity - MyActivity.CurrentInstance.CreateNotification(...) - my notification does not react on swipe-to-dismiss event. I even tried to put the CreateNotification's code in RunOnUiThread - no result.
Therefore, notification's swipe-to-dismiss event is triggered only in case if that notification has been created in my activity. But I create notifications when receive messages from GCM. It actually creates notifications even when application is not running.
public void CreateNotification(........) {
//RunOnUiThread(() => {
var notificationBuilder = new Notification.Builder(this);
notificationBuilder.SetContentTitle(title);
notificationBuilder.SetContentText(description);
notificationBuilder.SetSmallIcon(Resource.Drawable.Icon);
var notificationIntent = new Intent(this, typeof(MainActivity));
notificationIntent.PutExtra(.......)
var contentIntent = PendingIntent.GetActivity(Application.Context, 0, notificationIntent, PendingIntentFlags.CancelCurrent);
notificationBuilder.SetContentIntent(contentIntent);
// Actually my headache
const String NOTIFICATION_DELETED_ACTION = "NOTIFICATION_DELETED";
var receiver = new MyBroadcastReceiver();
RegisterReceiver(receiver, new IntentFilter(NOTIFICATION_DELETED_ACTION));
Intent intent = new Intent(NOTIFICATION_DELETED_ACTION);
intent.PutExtra(.......)
var deleteIntent = PendingIntent.GetActivity(Application.Context, 0, intent, PendingIntentFlags.CancelCurrent);
notificationBuilder.SetDeleteIntent(deleteIntent);
var notificationManager = GetSystemService(Context.NotificationService) as NotificationManager;
notificationManager.Notify(1, notificationBuilder.Build());
//});
}
Any ideas how to create a notification (inside the service) that will be able to trigger its swipe-to-dismiss event?

notification's swipe-to-dismiss event is triggered only in case if that notification has been created in my activity
When you When you use SetDeleteIntent(deleteIntent) method, make sure your deleteIntent is initialized by using PendingIntent.GetBroadcast method.
GetBroadcastet means retrieve a PendingIntent that will perform a broadcast, like calling Context.sendBroadcast(). When you use GetActivity method, it means retrieve a PendingIntent that will start a new activity. That's reason that your notification does not trigger OnReceive in the BroadcastReceiver. For more information you could read this document.
Modify your code :
var deleteIntent = PendingIntent.GetActivity(Application.Context, 0, intent, PendingIntentFlags.CancelCurrent);
To :
var deleteIntent = PendingIntent.GetBroadcast(Application.Context, 0, intent, PendingIntentFlags.CancelCurrent);
Then in your GCM Service, your notification's swipe-to-dismiss event will be triggered .

Stop Process when Notification is Cleared

I want the application process to be killed when the user slides the notification off the screen or hits the clear all notifications button.
Is there a way to implement this?

DeleteIntent: DeleteIntent is a PendingIntent object that can be associated with a notification and gets fired when the notification gets deleted.
You can set the Pending Intent to a broadcast Receiver and then perform any action you want.
Intent intent = new Intent(this, MyBroadcastReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 0, intent, 0);
Builder builder = new Notification.Builder(this):
..... code for your notification
builder.setDeleteIntent(pendingIntent);
MyBroadcastReceiver
public class MyBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
//code to kill app
c̶o̶n̶t̶e̶x̶t̶.̶f̶i̶n̶i̶s̶h̶A̶f̶f̶i̶n̶i̶t̶y̶(̶)̶;̶
ActivityCompat.finishAffinity((Activity)context);
}
}

Android stop Service using (Pending) Intent

I have the method
private Notification getNotification() {
Activity currentActivity = MyApplication.getApplication().getCurrentActivity();
Intent i = new Intent(currentActivity, SpeechActivationService.class);
i.putExtra(ACTIVATION_STOP_INTENT_KEY, true);
PendingIntent resultPendingIntent = PendingIntent.getActivity(currentActivity, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Action action = new NotificationCompat.Action(R.drawable.ic_mic_off, "Deactivate", resultPendingIntent);
Notification notification = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_mic)
.setTicker("TickerSample")
.setWhen(System.currentTimeMillis())
.setContentTitle("My App Voice Control")
.setContentText("Voice Control is Activated")
.addAction(action)
.build();
return notification;
}
It is supposed to make a notification which stays active for as long as the service is active. The notification has a DEACTIVATE Button, which can send an Intent, wrapped in a Pending Intent (whatever the difference is?!). It seems Intents are the only form of Action a notification can take for handling Button clicks, so I can't just do
stopService(new Intent(this, SpeechActivationService.class));
on that DEACTIVATE. But with my code onStartCommand() in SpeechActivationService never gets called when I click on DEACTIVATE. And Services don't inherit an onNewIntent() method. So what method gets called when I send this intent by pressing DEACTIVATE?

So what method gets called when I send this intent by pressing DEACTIVATE?
Nothing will. You are attempting to use a getActivity() PendingIntent with an Intent that points to a service. This will not work, and you should be getting messages in LogCat to that effect.
If you change getActivity() to getService(), then onStartCommand() of your service should be called.

Pending intents is ment to be used for controlling stuff outide of your app (system features use those). For stopping service create BroadcastReceiver, which will receive pending intent (PendingIntent.getBroadcast()), which, in turn, will stop your Service
