Volume change trigger

[AJ Puzon]

Is there any way to monitor Volume changes via tasker or by a plugin?

Yes, several depending on what you want to achieve.

Use a profile Event 'Variable Set' on one of the many global volume variables such as, volume - system '%VOLS'.

Take a look at the variables page of the user guide for more info.

[Thom Little]

(1) Triggering by volume variable change is an interesting idea.  There are some limitations …

 

%VOLA does not trigger

%VOLC does not trigger

%VOLM trigger with change by 1

%VOLD trigger with change greater than 1

%VOLN trigger with change by 1

%VOLR trigger with change by 1

%VOLS trigger with change by 1

 

The seven profiles to trigger …

Profile: VolA (532)
Event: Variable Set [ Variable:%VOLA Value:* User Variables Only:Off ]
Enter: VolAll (533)
A1: Beep [ Frequency:8000 Duration:1000 Amplitude:50 Stream:3 ]
A2: Flash [ Text:a%VOLA c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:Off ]

Profile: VolC (536)
Event: Variable Set [ Variable:%VOLC Value:* User Variables Only:Off ]
Enter: VolAll (533)
A1: Beep [ Frequency:8000 Duration:1000 Amplitude:50 Stream:3 ]
A2: Flash [ Text:a%VOLA c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:Off ]

Profile: VolD (538)
Event: Variable Set [ Variable:%VOLD Value:* User Variables Only:Off ]
Enter: VolAll (533)
A1: Beep [ Frequency:8000 Duration:1000 Amplitude:50 Stream:3 ]
A2: Flash [ Text:a%VOLA c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:Off ]

Profile: VolM (537)
Event: Variable Set [ Variable:%VOLM Value:* User Variables Only:Off ]

A2: Flash [ Text:a%VOLA c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:Off ]

Profile: VolN (539)
Event: Variable Set [ Variable:%VOLN Value:* User Variables Only:Off ]
Enter: VolAll (533)
A1: Beep [ Frequency:8000 Duration:1000 Amplitude:50 Stream:3 ]
A2: Flash [ Text:a%VOLA c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:Off ]

Profile: VolR (540)
Event: Variable Set [ Variable:%VOLR Value:* User Variables Only:Off ]
Enter: VolAll (533)
A1: Beep [ Frequency:8000 Duration:1000 Amplitude:50 Stream:3 ]
A2: Flash [ Text:a%VOLA c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:Off ]

Profile: VolS (531)
Event: Variable Set [ Variable:%VOLS Value:* User Variables Only:Off ]
Enter: VolAll (533)
A1: Beep [ Frequency:8000 Duration:1000 Amplitude:50 Stream:3 ]
A2: Flash [ Text:a%VOLA c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:Off ]

(2) It would be great if I could combine them all into a single profile.

Hi Thom,

(2) It would be great if I could combine them all into a single profile.

You probably could with an Intent Received, Event.

android.media.VOLUME_CHANGED_ACTION

[Thom Little]

That worked liked a champ.

The three restrictions I documented from the other approach are not present in this approach.  (Another "feature" Pent?)  The profile ...

Profile: VolAll (549)
Event: Intent Received [ Action:android.media.VOLUME_CHANGED_ACTION Cat:None Cat:None Scheme:* Mime Type:* ]

Enter: VolAll (533)
A1: Beep [ Frequency:8000 Duration:1000 Amplitude:50 Stream:3 ]
A2: Flash [ Text:a%VOLA c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:Off ]

... Thom

[Thom Little]

In the first method there is no way to trigger a BTvoice change because there is no global variable.

In the Intent method a BTvoice change triggers.

BT appears not to be documented.

Use the extras to create your own,

IF, %android_media_extra_volume_stream_type_alias = 6

Var Set, %VOLBT - %android_media_extra_volume_stream_value

[Thom Little]

You have really caught my attention.  I have used intents very little up until now and do not quite understand what you are telling me or what is written in the user guide.

What I would love to have is a variable %VOLBT that contained the value of BT Voice Volume.

Dev2 (217)
A1: If [ %android_media_extra_volume_stream_type_alias eq 6 ]
A2: Variable Set [ Name:%VOLBT To:%android_media_extra_volume_stream_value Recurse Variables:Off Do Maths:Off Append:Off ]
A3: End If
A4: Flash [ Text:%VOLBT Long:Off ]

Sorry. I was referring to androids developer docs.

BT stream isn't documented.

What I would love to have is a variable %VOLBT that contained the value of BT Voice Volume.

Dev2 (217)
A1: If [ %android_media_extra_volume_stream_type_alias eq 6 ]
A2: Variable Set [ Name:%VOLBT To:%android_media_extra_volume_stream_value Recurse Variables:Off Do Maths:Off Append:Off ]
A3: End If
A4: Flash [ Text:%VOLBT Long:Off ]

That task attached to the previously created 'intent' profile should allow you to monitor the BT stream.

[Thom Little]

The following is a profile to set it and a test task to manipulate it.  There are two remaining challenges …

 

It has to be run once to finalize the global variable with the correct value.

There is a half second wait before the Flash.  Without it the Flash was executing before %VOLB as set.

 

Profile: VOLB

Event: Intent Received [ Action:android.media.VOLUME_CHANGED_ACTION Cat:None Cat:None Scheme:* Mime Type:* ]

Enter: Anon
A1: Variable Set [ Name:%VOLB To:%android_media_extra_volume_stream_value Recurse Variables:Off Do Maths:Off Append:Off ] If [ %android_media_extra_volume_stream_type_alias eq 6 ]

 

Test

A1: Alarm Volume [ Level:7 Display:Off Sound:Off ]
A2: BT Voice Volume [ Level:15 Display:Off Sound:Off ]
A3: In-Call Volume [ Level:8 Display:Off Sound:Off ]
A4: Wait [ MS:500 Seconds:0 Minutes:0 Hours:0 Days:0 ]
A5: Variable Set [ Name:%VOLB To:?  Recurse Variables:Off Do Maths:Off Append:Off ] If [ %VOLB !Set ]
A6: Flash [ Text:a%VOLA b%VOLB c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:On ]

Hi Thom,

It has to be run once to finalize the global variable with the correct value.

Why bother to initiate the variable it will be set when a corresponding event occurs?

[Thom Little]

I was trying to create a real %VOLB.  I would like to report the current value as the first reference.

I use the following a lot ...

A1: Flash [ Text:a%VOLA b%VOLB c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:Off ]

... and would like to use it before the user sets %VOLB.

... Thom

[Thom Little]

Is there a way to fake it out?  If uninitialized do something like set one of the other volumes with a value that it already has and then access the value for %VOLB?

I'm still a newbie in this area and experimentation  didn't turn anything up.

.... Thom

[Sean Williams]

I use the following a lot ...
A1: Flash [ Text:a%VOLA b%VOLB c%VOLC m%VOLM • d%VOLD n%VOLN r%VOLR s%VOLS Long:Off ]
... and would like to use it before the user sets %VOLB.

If you're displaying the current value you shouldn't rely on the intent instead check what the actual value is.


Java actions,

Ret, audiomgr Class,AudioManager Function, new Par, CONTEXT

Ret, %VOLB Class,audiomgr Function, getStreamVolume Par, 6

[Thom Little]

My first time on this path ... ever.  Any help would be greatly appreciated.  The following fails ...

getVOLB
A1: JavaScriptlet [ Code:Ret, %VOLB Class, audiomgr Function, getStreamVolume Par, 6 Libraries: Auto Exit:On Timeout (Seconds):45 ]
A2: Flash [ Text:%VOLB Long:Off ]

... Thom

[Sean Williams]

Hi Thom,

My first time on this path ... ever. Any help would be greatly appreciated. The following fails ...

You'll need to use Java (not JavaScript).

See below,

Audio BT (610)
A1: Java Function [ Return:audiomgr Class Or Object:AudioManager Function:new
{AudioManager} (Context) Param:CONTEXT Param: Param: Param: Param: Param: Param: ]
A2: Java Function [ Return:%VOLB Class Or Object:audiomgr Function:getStreamVolume
{int} (int) Param:6 Param: Param: Param: Param: Param: Param: ]
A3: Flash [ Text:%VOLB Long:Off ]

[Thom Little]

Never been here before ...

In Code / Java Function / Function I entered ...

[ Return:audiomgr Class Or Object:AudioManager Function:new
{AudioManager} (Context) Param:CONTEXT Param: Param: Param: Param: Param: Param: ]

... and when I clicked the back arrow it gave the error ...

Function: Invalid value

... Thom

[Sean Williams]

You could try using the magnifying glass and or coffee cup to populate the fields.

Also create another Java function for Action 2.

[Thom Little]

I got it working.

As the first ever function I can testify that data entry is obscure.

Thanks for the help.

Reporting on 8 instead of 7 volume levels is more complete.  Perhaps Pent will consider adding %VOLB.

Thanks again.

... Thom
