How to open pdf from a notification

问题

I want to open pdf when i press on the notification i tried to to this:

public void addNotification(String path) {
    createNotificationChannel();

    File file = new File(path); // set your audio path
    Intent intent = new Intent();
    intent.setData(Uri.fromFile(file));
    intent.setAction(android.content.Intent.ACTION_VIEW);
    PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);


    //Intent landingIntent = new Intent(this, MainActivity.class);
   // landingIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TASK);
   // PendingIntent pendingIntent= PendingIntent.getActivity(this, 0,landingIntent, PendingIntent.FLAG_ONE_SHOT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "0");
    builder.setSmallIcon(R.drawable.ic_notification);
    builder.setContentTitle(nomePdf + " creato");
    builder.setContentText("Il tuo pdf è stato salvato nella cartella download");
    builder.setPriority(NotificationCompat.PRIORITY_DEFAULT);
    builder.setContentIntent(pIntent);


    NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(this);
    notificationManagerCompat.notify(0, builder.build());
}

public void createNotificationChannel(){
    CharSequence name = "Personal";
    String description = "";
    int importance = NotificationManager.IMPORTANCE_DEFAULT;

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        NotificationChannel notificationChannel = new NotificationChannel("0", name, importance);
        notificationChannel.setDescription(description);
        NotificationManager notificationManager= (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        notificationManager.createNotificationChannel(notificationChannel);
    }
}

but i get this error:
