AndroidNotificationChannel.LockScreenVisibility.Private not working about com.unity.mobile.notifications HOT 7 CLOSED

Thanks for reporting this.
I don't know why it's -1000 at the beginning, but you're right according to the android doc. Will have a check.

Thanks! So it's a different story on device below Android 8, as there is no notification channel support.

from com.unity.mobile.notifications.

I looked into this issue today, would like to share what I found.

1. Android document said VISIBILITY_PUBLIC is 1, https://developer.android.com/reference/android/app/Notification#VISIBILITY_PUBLIC. But I found if you set a channel to Show all notifications ... in System Settings, NotificationChannel.getLockscreenVisibility() will return -1000. Also if you don't set the LockScreenVisiblity when creating the notification channel, it will be -1000 by default.

2. NotificationChannel.setLockscreenVisibility() won't work from code anyway. check the comment here by searchingOnly modifiable by the system and notification ranker.. This means the value can only be changed from System settings or by Android Notification Ranking Service. I did a quick experiment by doing below

    protected void createNotificationChannel(NotificationManager notificationManager)
    {
        NotificationChannel channel = new NotificationChannel(k_ChannelId, "Test Default", NotificationManager.IMPORTANCE_DEFAULT);

        Log.w("Create Channel", String.format("Default lockscreen: %d", channel.getLockscreenVisibility()));
        channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
        Log.w("Create Channel", String.format("Set lockscreen %d", channel.getLockscreenVisibility()));

        notificationManager.createNotificationChannel(channel);
    }

    protected void printNotificationChannel(NotificationManager notificationManager)
    {
        NotificationChannel channel = notificationManager.getNotificationChannel(k_ChannelId);
        Log.w("Print Channel", String.format("Get lockscreen %d", channel.getLockscreenVisibility()));
    }

I got the below results

2020-04-13 16:52:38.320 17408-17408/com.example.testvibration W/Create Channel: Default lockscreen: -1000
2020-04-13 16:52:38.321 17408-17408/com.example.testvibration W/Create Channel: Set lockscreen 0
2020-04-13 16:52:49.375 17408-17408/com.example.testvibration W/Print Channel: Get lockscreen -1000

Then I went to System Settings to change the lockscreen visibility to Hide senstitive ....(private), I got

2020-04-13 16:57:36.180 17408-17408/com.example.testvibration W/Print Channel: Get lockscreen 0

At last I switched back to Show all notification contents, I got,

2020-04-13 16:59:36.190 15045-15045/com.example.testvibration W/Print Channel: Get lockscreen -1000

So my conclusions are

• you can't really set the lockscreen visibility from code...
• -1000 stands for public

And my question is do we really provide LockScreenVisibility setter for NotificationChannel...

Interesting, thanks for the heads up Vincent!

If I use AndroidNotificationCenter.RegisterNotificationChannel passing a channel where 'LockScreenVisibility' has been seto to 'LockScreenVisibility.Secret', the channel seems to work as intended. I can't see any notification fired on that channel in the lock screen.

from com.unity.mobile.notifications.

So weird... We have tests on NotificationChannel which all the returned value of NotificationChannel.LockscreenVisibility are Public, no matter which value you set on creation. I'm personally testing on Google Pixel 2 with Android 8.

So could you please check what NotificationChannel.LockscreenVisiblity returns for a registered channel? Please use AndroidNotificationCenter.GetNotificationChannel() to retreive the registered channel. I'm expecting it returns Private (which should be Public as I'm going to fix).

Btw, you have to uninstall/reinstall the app to test as you can't change an registered notfication channel from code per Android!

Sorry for the late answer Vincent,
so I have performed the test you asked me. To be clear I am using the version 1.0.3 of the mobile notification package and I am testing on a very old KitKat Android phone.

After registering three different channels with the three different visibility values this is the output:

I/Unity: The visibility for the channel 'game_normal_channel' is: Public
I/Unity: The visibility for the channel 'game_private_channel' is: Private
I/Unity: The visibility for the channel 'game_silent_channel' is: Secret

I confirm that the 'Public' and the 'Secret' channel work just fine while the 'Private' one bahaves like the 'Public' one.

Fixed in 1.2.0-preview.
