Android Question BroadCastReceiver to know VOLUME_UP or VOLUME_DOWN is pressed

[Albert Lin]

Dear All

I use BroadCastReceiver to detect KEYCODE_VOLUME_UP or KEYCODE_VOLUME_UP pressed
the code is as following. but how to know which key is pressed? Is KEYCODE_VOLUME_UP or KEYCODE_VOLUME_UP?

Best Regards
Albert Lin

Sub Service_Create
    Broadcast.Initialize("BR")
   
End Sub

Sub Service_Start (StartingIntent As Intent)
    Broadcast.SetPriority(2147483647)   
    Broadcast.registerReceiver("android.media.VOLUME_CHANGED_ACTION")
       
End Sub

Sub Service_Destroy
    Broadcast.unregisterReceiver
End Sub
Sub BR_OnReceive(Action As String, Extras As Object)
   
    gVibrate.Vibrate (190)
    CallSubDelayed(Main, "btnSave_Click")
    ToastMessageShow(Action,False)
    
End Sub

Note that it is better to register it in Service_Create. Service_Start can be called multiple times.

What is the output of Log(Extras)?
