Running application in background with progress notification

Question

I'm doing a download process using asyncTask over a webview so that downloading process will be happening until the app gets closed. Again when user opens the app, the downloading process continues. I tried running it in a backgroundService and i started the service once the app is stopped. The problem is service is getting started but when i close the app, the service stops. I also tried displaying notification while service is running but still when i close the app, service will be killed. I referred this post. Kindly suggest me something where it solves me the problem and that should work starting from Android lollipop till the latest.

Answer 1

I would suggest that a foreground service is the answer like in the link just additional with a notification channel

First check how to start the service with:

    Intent intent = new Intent(this@MainActivity, YourService::class.java);
            
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) 
        startForegroundService(intent);
    else 
        startService(intent);

Then from Service create a Notification channel before you setup the notification:

     private NotificationManager createNotificationChannel() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel serviceChannel = NotificationChannel(
                CHANNEL_ID, "NAME", NotificationManager.IMPORTANCE_DEFAULT
            );
            NotificationManager manager = getSystemService(NotificationManager::class.java);
            manager.createNotificationChannel(serviceChannel);
            return manager;
        }
        return null;
    }

Finally after that call:

Notification notification = mBuilder.build();
startForeground(1, notification);

Now should the notification be alive as long as your app is

If this doesn't work write to your registered service in manifest this

<service
     android:name=".YourService"
     android:stopWithTask="true" />
