Android Question [SOLVED] - Setting "do not disturb" mode

rleiman · Jan 26, 2020

Greetings,

Can B4A coding be used to set the "do not disturb" mode on the phone?

I found this coding on the forum to read what the current "do not disturb" mode is but I want to set that mode.

B4X:

    Dim ret As Int=-1
    Dim java As JavaObject
    java.InitializeContext
    Try
        ret =java.RunMethod("check_dnd",Null)
    Catch
        Log(LastException)
    End Try
  
    Select ret
      
    Case 0
        Log("DnD off")
    Case 2
        Log("Total Silence")
    Case 3
        Log("Alarms Only")
    Case -1
        Log("SettingNotFoundException occured ?")
    End Select

Thanks for the link. It instructed me to put the permission in the manifest editor which I did and also tried to put it in my list of permissions but it's not available as a member. Could it be called something else?

Despite not being able to include Permissions.Add(Starter.rp.PERMISSION_ACCESS_NOTIFICATION_POLICY) in my list of permissions for the app, I ran the app and the coding from your link and it called the screen that I needed to allow the app to access "Do not disturb". I was able to turn it on passing the number 2, but when I tried to pass it with number 0 to turn "Do not disturb" off, the app crashed. Looks like 0 is not a good number to pass. Also is there a way to not make the user not locate the app in the "Do not disturb" permission screen and allow the app to change "Do not disturb"?

All the information is included in that post.

No. It is not a "runtime permission". It is a special permission.

There is a link to the list of filters and their constant values.

This is the coding from the post I used to turn the "Do not disturb" on. I'm assuming the special permission you referred to is NOTIFICATION_POLICY_ACCESS_SETTINGS:

In the starter module:

Sub SetDoNotDisturb (Policy As Int)
    Dim NotificationManager As JavaObject
    NotificationManager = NotificationManager.InitializeContext.RunMethod("getSystemService", _
        Array("notification"))
    If NotificationManager.RunMethod("isNotificationPolicyAccessGranted", Null) = False Then
        Dim in As Intent
        in.Initialize("android.settings.NOTIFICATION_POLICY_ACCESS_SETTINGS", "")
        StartActivity(in)
        Wait For Activity_Resume '<---
        Log("after resume")
    End If
    If NotificationManager.RunMethod("isNotificationPolicyAccessGranted", Null) = True Then
        NotificationManager.RunMethod("setInterruptionFilter", Array(Policy))
    Else
        Log("No permission!")
    End If
End Sub

These are the permissions I'm using in the manifest editor:

In the manifest editor:

AddPermission(android.permission.SEND_SMS)
AddPermission(android.permission.RECEIVE_SMS)
AddPermission(android.permission.READ_PHONE_STATE)
AddPermission(android.permission.READ_CALL_LOG)
AddPermission(android.permission.CALL_PHONE)
AddPermission(android.permission.ACCESS_FINE_LOCATION)
AddPermission(android.permission.ACCESS_NOTIFICATION_POLICY)
AddPermission(android.settings.NOTIFICATION_POLICY_ACCESS_SETTINGS)

Is the NOTIFICATION_POLICY_ACCESS_SETTINGS line in the manifest editor correct? I still can't turn the "Do not disturb" off without the app crashing. Looks like 0 is not the correct number to pass.

All help is appreciated.

No it is not. See the list of constants: https://developer.android.com/refer...cationManager.html#INTERRUPTION_FILTER_ALARMS

If it appears in that post, then yes it is correct.

I looked at the interruption filters and yes it looks like 0 is to turn it off. Since I don't know Java, the Java documentation in the link is very confusing.

I found in the post this line:

B4X:

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

So I changed my manifest editor to look this this:

B4X:

AddPermission(android.permission.SEND_SMS)
AddPermission(android.permission.RECEIVE_SMS)
AddPermission(android.permission.READ_PHONE_STATE)
AddPermission(android.permission.READ_CALL_LOG)
AddPermission(android.permission.CALL_PHONE)
AddPermission(android.permission.ACCESS_FINE_LOCATION)

AddManifestText(
<uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY" />)
AddPermission(android.permission.ACCESS_NOTIFICATION_POLICY)

So I think I have all of the code correct based on the post but the app still crashes when 0 is passed to the sub routine. Please look at my log dump.

Please forgive me if I don't understand Java.

You don't need to add anything else. There is nothing related to Java here.

Where have you seen it?

0 = FILTER_UNKNOWN: https://developer.android.com/refer...ationManager.html#INTERRUPTION_FILTER_UNKNOWN

@rleiman 1 = Off and 2 = On...

Hi Peter,

Thank you so much
It works perfect.

Is there a way to change the coding so the user is not required to navigate the "Do not disturb permission" screen the first time the app is run? If not, I will give the user instructions on working with that screen.

Thanks again.
