Cannot disable notification vibration in Android 8

Question

I try to disable vibration when showing a notification.

Func:

public static Notification buildNotifForUploaderService(Context ctx, String title, String message) {

        Notification notification;
        NotificationCompat.Builder notificationBuilder;

        //If device is Android 8+
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel notificationChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
            //setting pattern to disable vibrating
            notificationChannel.setVibrationPattern(new long[]{0L});
            notificationBuilder = new NotificationCompat.Builder(ctx, CHANNEL_ID);
        } else {
            notificationBuilder = new NotificationCompat.Builder(ctx);
            notificationBuilder.setVibrate(new long[]{0L});
        }


        notificationBuilder
                .setContentTitle(title)
                .setContentText(message)
                .setLargeIcon(BitmapFactory.decodeResource(ctx.getResources(), R.mipmap.ic_launcher))
                .setSmallIcon(R.drawable.ic_backup_black_24dp);


        notification = notificationBuilder.build();

        return notification;
    }

I call this on an activity's onCreate() like this:

Notification notification = NotificationHelper.buildNotifForUploaderService(this, "title", "message");
    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(1, notification);

It is still vibrating. I test on Android 8 device. I have also tried

 notificationChannel.setVibrationPattern(null);

still not works.

I have

<uses-permission android:name="android.permission.VIBRATE" />

No matter how I define the vibration pattern, like:

new long[]{1000L, 500L, 300L, 1000L};

The vibration does not correspond to my settings. Onyl the default "two short" vibration occurs.

Please help if you can, thanks in advance.

As Avijit Karmakar mentioned, I have added

  notificationChannel.enableVibration(false);

Full code now:

public class MainActivity extends AppCompatActivity {

    final static String CHANNEL_ID = "MY_CHANNEL_ID";
    final static String CHANNEL_NAME = "MY_CHANNEL_NAME";


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Notification notification;
    NotificationCompat.Builder mBuilder;
    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);


    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel notificationChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
        //Disabling vibration!
        notificationChannel.enableVibration(false);
        notificationManager.createNotificationChannel(notificationChannel);
        mBuilder = new NotificationCompat.Builder(this, CHANNEL_ID);

    } else {
        mBuilder = new NotificationCompat.Builder(this);
        mBuilder.setVibrate(new long[]{0L});
    }

    mBuilder.setContentTitle("title")
            .setContentText("message")
            .setSmallIcon(R.drawable.ic_android_black_24dp);

    Bitmap bm = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
    mBuilder.setLargeIcon(bm);

    notification = mBuilder.build();
    notificationManager.notify(1, notification);
    }
}

It is still vibrating.

I test on Xiaomi Mi A1 (Android 8.0)

Can anybody try this code and help me with the results?

Answer 1

Like this answer, do:

mNotificationChannel.setVibrationPattern(new long[]{ 0 }); 
mNotificationChannel.enableVibration(true);

Important 1: even if I set the vibration pattern above, but set enableVibration to false, it vibrates. So, set enableVibration to true!

Important 2: like this another answer, the channel keeps its initial settings, so uninstall and install the app again to apply the changes!

Hope it helps!
