Notification crashes app in notify method

Question

I have been trying to display a notification but it either doesn't show or causes a fatal error inside the notify method. This notification is supposed to effectively be a toast that will stay in the notification drawer until tapped.

I've tried several different intents including none. I have also, at points, copied an entire example in which still didn't work.

I have no clue what's causing the error and I've tried to attach a logcat into the app but I wasn't able to get anything out.

I'm using a Pixel 2 running stock 8.1; my programming is on the phone itself so I can't use adb / root options

  public int noti(String title, String body, String ico){
//Bitmap bitmap = ((BitmapDrawable)drawable).getBitmap();
showToast(title+">"+body+">"+ico);
try{
  Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.google.com/"));
  PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
  Notification.Builder mBuilder =
    new Notification.Builder(getApplicationContext(), "83")
      .setSmallIcon(Icon.createWithContentUri(ico))
      .setContentTitle(title)
      .setContentText(body)
      .setOngoing(true)
      .setContentIntent(pendingIntent)
      .setPriority(NotificationCompat.PRIORITY_DEFAULT);
  NotificationManagerCompat notificationManager = NotificationManagerCompat.from(getApplicationContext());
  Notification noti = mBuilder.build();
  if(noti==null){
    logBack("noti.builder == null.");
    return -2;
  }
  int notificationId = notiIDz.getAndIncrement();
  // notificationId is a unique int for each notification that you must define
  notificationManager.notify(notificationId, noti);
  return notificationId;
} catch(Exception e){
  logBack(e.toString());
}
return -1;

}

I know that the parameters are valid from the toast, I also know that none of the logBack()s are fired.

Notification channel creation, called during onCreate:

private void createNotificationChannel() {
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
  NotificationChannel channel = new NotificationChannel("83", "vzyNotiChan", NotificationManager.IMPORTANCE_DEFAULT);
  channel.setDescription("The notification channel for vzy apps.");
  // Register the channel with the system; you can't change the importance
  // or other notification behaviors after this
  NotificationManager notificationManager = getSystemService(NotificationManager.class);
  notificationManager.createNotificationChannel(channel);
  }

}

Edit, finally got to the logcat:07-24 10:48:10.879 27133 27133 E AndroidRuntime: android.app.RemoteServiceException: Bad notification posted from package vzy.html.tester: Couldn't create icon: StatusBarIcon(icon=Icon(typ=URI uri=content://com.android.externalstorage.documents/document/primary%3Ayp_sodapop.png) visible user=0 )

I haven't been able to get anything from my logcat attempts, I need to call it from inside the app so my options are abit more limited. — vzybilly, Jul 23 '18 at 15:50
try writing `e.printstacktrace()` in the catch block and check for the exception again. — Atish Agrawal, Jul 23 '18 at 15:54
I added both a printstackTrace and one for an output file, the catch isn't being fired... — vzybilly, Jul 23 '18 at 16:05
I was working around with it and found that the code I found to get the logcat was throwing an exception but they did nothing with it since it was a logger itself... I'm going through and trying to debug it — vzybilly, Jul 24 '18 at 14:07

My guess is that you didn't create a notification channel for your notification. On All Android devices running 8.0+, each notification needs to be associated to a notification channel. You're passing in the channel ID "83" to the notification builder, but maybe you haven't actually created the channel beforehand.
