Oreo - Starting a service in the foreground

Question

I have created a service that tracks the device\'s location as it moves. The service is started in by an Activity that binds to it, and in this activity there is a \"Start T

Try to change your startInForeground() method with this code:

private void startInForeground() {
        Intent notificationIntent = new Intent(this, WorkoutActivity.class);
        PendingIntent pendingIntent=PendingIntent.getActivity(this,0,notificationIntent,0);
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this,NOTIFICATION_CHANNEL_ID)
                .setSmallIcon(R.drawable.shsl_notification)
                .setContentTitle("TEST")
                .setContentText("HELLO")
                .setTicker("TICKER") 
                .setContentIntent(pendingIntent);
        Notification notification=builder.build();
        if(Build.VERSION.SDK_INT>=26) {
            NotificationChannel channel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, NOTIFICATION_CHANNEL_NAME, NotificationManager.IMPORTANCE_DEFAULT);
            channel.setDescription(NOTIFICATION_CHANNEL_DESC);
            NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManager.createNotificationChannel(channel);
        }
        startForeground(NOTIFICATION_ID, notification);
}

So, when your Android version is Oreo (or higher) notification channel will be created, otherwise not.

Before show notification you have to create notification channel:

private void createNotificationChannel() {
    if (Build.VERSION_CODES.O <= Build.VERSION.SDK_INT) {
        NotificationChannel notificationChannel =
                new NotificationChannel(PRIMARY_CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_DEFAULT);
        notificationManager.createNotificationChannel(notificationChannel);
    }
}

and then change create notification builder

new Notification.Builder(context, PRIMARY_CHANNEL_ID)
