Change volume

[WAZUMBi]

OK so I've tried:

   If KeyCode = KeyCodes.KEYCODE_VOLUME_DOWN Then
      If phoneData.GetVolume(phoneData.VOLUME_MUSIC) > 0 Then
         phoneData.SetVolume(phoneData.VOLUME_MUSIC, phoneData.GetVolume(phoneData.VOLUME_MUSIC) - 1, True)
      End If   
   End If
   
   If KeyCode = KeyCodes.KEYCODE_VOLUME_UP Then
      If phoneData.GetVolume(phoneData.VOLUME_MUSIC) < phoneData.GetMaxVolume(phoneData.VOLUME_MUSIC) Then
         phoneData.SetVolume(phoneData.VOLUME_MUSIC, phoneData.GetVolume(phoneData.VOLUME_MUSIC) + 1, True)
      End If   
   End If

And my program just crashes and i get an Andoid system error message

So then I tried to break it down with:

dim temp as int

   If KeyCode = KeyCodes.KEYCODE_VOLUME_DOWN Then      
      temp = phoneData.GetVolume(phoneData.VOLUME_MUSIC)
      If temp > 0 Then
         temp = temp - 1
         phoneData.SetVolume(phoneData.VOLUME_MUSIC, temp, True)
      End If      
   End If

   If KeyCode = KeyCodes.KEYCODE_VOLUME_UP Then      
      temp = phoneData.GetVolume(phoneData.VOLUME_MUSIC)
      If temp < phoneData.GetMaxVolume(phoneData.VOLUME_MUSIC) Then
         temp = temp + 1
         phoneData.SetVolume(phoneData.VOLUME_MUSIC, temp, True)
      End If      
   End If

This does change the volume AND then crashes with the same Android system error message.

Any ideas what I'm doing wrong here?

Which error message?

You should check the logs and post the full error message.

 

[WAZUMBi]

pretty generic:

"Sorry! The application interblock(process interblock.Interblock) has stopped unexpectedly. Please try again."

Still trying to figure out how to use logcat

 

[WAZUMBi]

Log(KeyCode)
Log(phoneData.GetVolume(phoneData.VOLUME_MUSIC))
Log(phoneData.GetMaxVolume(phoneData.VOLUME_MUSIC))

When I press volume down the log shows
25
3
15

volume up shows
24
4
15

no errors show up in the log

Just go to the Logs tab:

Alright figured that out.

Your event sub is probably not declared correctly.

It should be:

Sub Activity_KeyPress (KeyCode As Int) As Boolean 
   
End Sub

You should not write it manually. Instead see this tip: http://www.b4x.com/forum/basic4android-getting-started-tutorials/6546-ide-tips.html#post38342

Thank you. That worked like a charm.

Now the ringer and media volume changes though. I was assuming
VOLUME_MUSIC set the media volume on my device.

I figured out if i return true it appears to work fine now however the logs show:

The system is doing 2 calls - one to channel 3 and then to channel 2. Only the music volume is changed though.

I ran a different app from the market and when I press the volume buttons it also makes two calls but both are to channel 3.

So while my code works, it appears to be doing it incorrectly.
