PendingIntent completion

Question

I record this in the service:

    intent = new Intent(this,MainActivity_Large.class);

    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
            Intent.FLAG_ACTIVITY_SINGLE_TOP); 

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,  0);


   
            NotificationCompat.Builder builder =
            new NotificationCompat.Builder(this,CHANNEL_ID)
                    .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                    .setAutoCancel(true)
                    .setChannelId(CHANNEL_ID)
                    .setDefaults(Notification.DEFAULT_ALL)
                    .setSmallIcon(R.drawable.ant_intro)
                    .setContentTitle("Anttack")
                    .setContentText("Continues")
                    .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                    //     .setPriority(2)
                    .setContentIntent(pendingIntent);

    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        builder.setCategory(Notification.CATEGORY_SERVICE);
    }

    notification = builder.build();
    startForeground(1, notification);

After the device goes to sleep and wakes up, a notification appears on the screen. If you click on it, the minimized activity will be restored.

How can i track completion of PendingIntent?

Maybe someone knows how to use PendingIntent.onFinished?

Answer 1

There are some Activity methods which will help you to find out whether the Activity comes to the foreground because the user tapped the notification:

getIntent() will give you the Intent which triggered Activity creation if tapping the notification happens when the Activity has to be (re)created.

Overriding onNewIntent() will give you access to the Intent responsible for re-launching an existing Activity. Note that you also have the opportunity to set the new Intent as "the" Intent for this Activity:

@Override
protected void onNewIntent(Intent newIntent){
    setIntent(newIntent);
}

So you can put a boolean as Intent extra when creating the Intent for your PendingIntent ...

intent = new Intent(this,MainActivity_Large.class);
intent.putExtra("FROM_NOTIFICATION", true);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
        Intent.FLAG_ACTIVITY_SINGLE_TOP); 

... and evaluate this in your code, e.g. in Activity.onResume()

@override
protected void onResume(){
    if(getIntent().hasExtra("FROM_NOTIFICATION")){
        // Activity was (re-)launched because user tapped notification
    }
}

I'm aware that this way you won't be able to tell when the user taps the notification a second time when the Activity is already up and running. Since I don't know your use case I can't tell whether this can happen or whether this would be a problem. But since you can also pass other data as Intent extra, it should be possible to identify each event if required.
