The app is fetching alert data from server. What I have to do is display the notification if app will get new alert. This should be happen even app is closed. Previously, I have worked on push notification where server is used to display the notification. But here I don't want to use push notification. So is there any way to achieve it?
Use the Notification API. Notification is a message you can display to the user outside of your application's normal UI. When you tell the system to issue a notification, it first appears as an icon in the notification area. To see the details of the notification, the user opens the notification drawer. Both the notification area and the notification drawer are system-controlled areas that the user can view at any time.
You might require a Service to accomplish your needs. Use a Service with the mentioned Notification API to send notifications even when the app is 'closed'.
no other way to this without using push notification and GCM

I am facing issue in my app regarding doze mode. I am making a chat application and when app is in backgroud during doze mode and receive any message . Device does not show notification in orea.
I have followed the proper procedure for OREO notification by building channel for it.
I need to find if there is a way to whiteList my app from doze mode so that I can have notifications. Or any other process to optimize notification building.
I do not need to whitelist my application to get notifications in doze mode. I recommend to look at your notification to see if you can find the issue there.
Some tips:
Send a notification, use the notification field. If theres no notification field it will be handled as a data notification. Data notifications are delivered when the app starts again.
Set priority to high.
Maybe use time to live = 0. That will make firebase to try harder to get it delivered. But it will be lost if it fails.
Hard to give you more direct advice when I do not know where you are sending the notification from.

I'm developing an app which receives data from server and if the data has some value, it will show some notification to user (DANGER STATUS or etc).
I read this : Android Notification: GCM or Service which says that GCM is much better than handling Notification in background-services. But as far as I know GCM also needs implementing background services(in app) to work. So what is the difference?
Is using GCM really more optimized than handling notification in background service? Both are background service...so why are they different?
Also GCM doesn't show the notification sometimes, and it's not
reliable.... this is why I'm thinking to implement notification in background-service.
What is the best way?
I want to schedule automatic push notifications trough Firebase for my Android App. I have already searched the documentation, but could not find a way to do this.
click on Send Later Button, then you can set the time for your Notification
You can do this through the Firebase Console. Go to the notifications tab and schedule a push notification.
If you want push notifications to be sent out periodically, you can set up a cron job in Firebase Functions.
How to check if “show notification” is enabled?
My app is integrated with parse.com and whenever it gets a response from parse.com, it generates a notification and shows it to user.
I need to know that if user has disabled "show notification" checkbox. I have to show a dialog as disabled to the user while trying to login. I haven't used notification service into my app.
Please make me suggestion on how to solve this.
When you know that your app is sending out a push notification you can check if it is in the Notification area. This is assuming your app's minimum SDK is 4.3 . Basically you are checking all active notifications to see if your notification is within the active notifications.

i create an application on my android device and i want run it when i receive a pushover notification. After i want passing the notification's text to my app. Is it possible?
thanks a lot
You make an application which subscribes to the notifications using
NotificationListenerService in Android 4.3 or Accessiblity Events in older versions of Android. See the following SO Answer for more information.
Also see the following example.
Then in either onNotificationPosted or onAccessibilityEvent your application should triggger your other application to launch using the method described in this SO answer.
This would allow you to start an application when any status bar notification was received from PushOver, and by filtering it to only notifications related to a new pushover notification, you would start an application when a new pushover notification was received.
In order to have the notifications text passed to your application or to filter based on the specific contents of the notification, you would need to subscribe to C2DM pushover messages which is protected by signature level protection, so without consulting the creators of pushover I don't believe that is possible.
