Solution 1:

For Oreo and above device have you try after create notification channel like below. Please have a look and let me know anything missing.

NotificationManagermNotificationManager= (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT  >= android.os.Build.VERSION_CODES.O) {
NotificationChannelchannel=newNotificationChannel(CHANNEL_ID, "A Word", NotificationManager.IMPORTANCE_LOW);
            mNotificationManager.createNotificationChannel(channel);
}
Notificationnotification=newNotificationCompat.Builder(getBaseContext(),CHANNEL_ID)
                            .setSmallIcon(R.drawable.nicon)
                            .setContentTitle("A Word")
                            .setAutoCancel(true)
                            .setContentText(bv)
                            .setContentIntent(contentIntent)
                            .build();
                    mNotificationManager.notify(0, notification);

Solution 2:

this code work fine in any version of android.

you can put this code to any brodcastresciver or some things like that (service , etc...)

Intent pIntent = new Intent(context, SecondActivity.class);
    mpIntent = PendingIntent.getActivity(context, 0, pIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    int notificationId = intent.getIntExtra("notificationId", 0);
    String message = intent.getStringExtra("todo");

    Intent mainIntent = new Intent(context, MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, mainIntent,PendingIntent.FLAG_ONE_SHOT );

    String channelId="channel_id";
    CharSequence name="channel_name";
    String descruption="description";
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
        NotificationChannel channel=new NotificationChannel(channelId,name,NotificationManager.IMPORTANCE_HIGH);
        channel.setDescription(descruption);
        NotificationManager notificationManager=context.getSystemService(NotificationManager.class);
        notificationManager.createNotificationChannel(channel);
    }


    NotificationCompat.BigTextStyle bStyle = new NotificationCompat.BigTextStyle()
            .setBigContentTitle("Your Title");

    Notification notification=new NotificationCompat.Builder(context,channelId)
                .setSmallIcon(R.drawable.notif_icon)
                .setVibrate(new long[]{100, 500, 500, 500, 500, 500})
              .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.logo))
                 .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                 .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setContentTitle("Your Title")
                .setContentText(message)
                .setDeleteIntent(contentIntent)
                .setStyle(bStyle)
                .setContentIntent(mpIntent)
                .setAutoCancel(true)
                .build();
    NotificationManagerCompat notificationManagerCompat=NotificationManagerCompat.from(context);
    notificationManagerCompat.notify(notificationId,notification);

With the help of the others on this forum I was able to put together the below code. Thank you all so much!

IntentnotificationIntent=newIntent(context, bibleReader.class);
    Bundlebundle=newBundle();
    notificationIntent.putExtras(bundle);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
    PendingIntentcontentIntent= PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    
    if(android.os.Build.VERSION.SDK_INT  >= android.os.Build.VERSION_CODES.O) {
        notificationChannel = newNotificationChannel(CHANNEL_ID, name, NotificationManager.IMPORTANCE_HIGH);
     }
    
    NotificationManagermNotificationManager= (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    
    if (android.os.Build.VERSION.SDK_INT  >= android.os.Build.VERSION_CODES.O) {
        mNotificationManager.createNotificationChannel(notificationChannel);
    }

    Notification.BigTextStylebigText=newNotification.BigTextStyle();
    bigText.bigText(textHere);
    bigText.setSummaryText(textHere);
    
    Notification.Builder NotificationBuilder;
    
    if (android.os.Build.VERSION.SDK_INT  >= android.os.Build.VERSION_CODES.O) {
    NotificationBuilder = newNotification.Builder(context, "ID");
    } else {
    NotificationBuilder = newNotification.Builder(context);
    }
    Notification.BuildermBuilder= NotificationBuilder;
    
    mBuilder.setSmallIcon(R.drawable.nicon);
    mBuilder.setContentTitle("text");
    mBuilder.setContentText(textHere);
    mBuilder.setStyle(bigText);
    mBuilder.setAutoCancel(false);
    mBuilder.setContentIntent(contentIntent);
    
    if (android.os.Build.VERSION.SDK_INT  >= android.os.Build.VERSION_CODES.O) {
    mBuilder.setChannelId(CHANNEL_ID);
    }
    mNotificationManager.notify(1, mBuilder.build());
