Bad notification for startForeground: invalid channel for service notification

[colorgold]

This is a great library, but after upgrading to Android API 28, I keep getting an error stating, "Bad notification for startForeground: java.lang.RuntimeException: invalid channel for service notification: Notification(channel=null..." I have already set "android.permission.FOREGROUND_SERVICE" in manifest as well as, "android:usesCleartextTraffic="true"." But, my app still crashes.

Any help will be greatly appreciated.

Thanks!

Pls update the Notification with channels to avoid the crash.

Thank you for replying. I am currently using an older version of the RadioPlayerService, but of course, it does not have the new features that the most current one has, which I want to use. So, if you don’t mind explaining, how do I go about updating the notification with channels? I will explain what I have tried so far:

-In my fragment class, I’ve implemented the RadioPlayerService and I am using RadioManager. -I tried creating my own service, but this just creates a new notification unrelated to the RadioPlayerService. -I’ve reviewed the classes in the library, but I don’t know how to edit them or implement them in my project

Again, thank you so much for reaching out; this has already given me a new idea of where to start looking for a fix.

I was able to fix it: String channelName = "My background Service"; if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) { NotificationChannel chan = new NotificationChannel(NOTIFICATION_CHANNEL_ID, ``channelName, NotificationManager.IMPORTANCE_DEFAULT); chan.setLightColor(Color.BLUE); chan.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);

        mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        assert mNotificationManager != null;
        mNotificationManager.createNotificationChannel(chan);`
