Action on notification clicked

Question

I need to change a variable only when a user clicks on a notification. I tried to use SharedPreferences in the activity after the notification redirects to it and then retake this variable next time I need it, but I don't know why it doesn't work.

Does anyone know where exactly does the onClick of the Notification is triggered ?

My notification is defined as follows:

protected Notification createNotification() {

    CharSequence title = "New notification";
    CharSequence content = "";

    Notification notification = new Notification(R.drawable.app_icon,
            title, System.currentTimeMillis());

    notification.flags = Notification.FLAG_AUTO_CANCEL;

    PendingIntent contentIntent = createPendingIntent();
    notification.setLatestEventInfo(this, title, content, contentIntent);
    return notification;
}

protected PendingIntent createPendingIntent() {
        Intent intent = new Intent(this, MainActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                intent, 0);
        return contentIntent;
    }

protected void showNotification() {
    try {
        mNM.notify(NOTIFICATION_ID, createNotification());
    } catch (Exception e) {

    }
}

Thank you.

Change variable in onCreate of `MainActivity` Activity because this Activity start when onClick of the Notification is triggered — ρяσѕρєя K, Feb 17 '15 at 08:54
That's exactly where I tried to change it, but when the notification is triggered again, the variable remains the same as before. — Phantom, Feb 17 '15 at 08:56
probably Activity is running in background when clicking second time on notification — ρяσѕρєя K, Feb 17 '15 at 09:01

If you would use a PendingIntent when clicking on the notification you can make it open an activity, when that activity is opened via an intent you can make the activity call a method. If you first would add the attribute below to your activity-tag in the AndroidManifest.xml.

android:launchMode="singleTop"

Add this method to your activity. This method is triggered when you are calling a intent to the activity. This is where

@Override
protected void onNewIntent(Intent intent) {
      super.onNewIntent(intent);
}

An alternative solution would be to create a custom notification with your own layout and use onClickListeners on the elements.

I'll do few more tries with my current configuration, because it seems onNewIntent doesn't work either. Then I'll probably opt for you alternative solution. – Phantom Feb 17 '15 at 09:10

Thanks for the support. I managed to resolved the problem. I got rid of the confirmation boolean variable when user was clicking the notification and changed the variable I was interested in directly. – Phantom Feb 17 '15 at 10:02
