Beep like function?

[hackhack]

Is there a way to play a beep sound without having to use external files? (like wav or midi)

 

[Erel]

No. You will need to play a sound file with MediaPlayer or SoundPool.

 

[hackhack]

Pity, it increases size.

Unless there are sound files in Android one can use? You know like Windows installs a set of beeps and pings for use in user interface?

 

[hackhack]

Btw, sorry, I just realized i basically asked this twice - forgot i had asked it already :-/

 

[Erel]

You will need to add the sounds files to your project.

 

[hackhack]

Actually I read that one can use the ringtones, like

MediaPlayer player = MediaPlayer.create(this,
    Settings.System.DEFAULT_RINGTONE_URI);
player.start();

Though more relevant would perhaps be DEFAULT_NOTIFICATION_URI - now to see if this works in b4a

 

[Erel]

Currently you will not be able to use it with Basic4android.

 

[hackhack]

Ok thanks.

 

[hackhack]

Hm, I see on both my phone and tablet in

/system/media/audio/

There are several audio files already in place.

Ahem! actually ...

Sub Btn1_Click
   Dim Obj1 As Reflector
   Obj1.Target = Obj1.CreateObject("android.provider.Settings$System")
   Obj1.Target = Obj1.GetField("DEFAULT_NOTIFICATION_URI")
   Dim args(2) As Object
   args(0) = Obj1.GetContext
   args(1) = Obj1.Target
   Dim types(2) As String
   types(0) = "android.content.Context"
   types(1) = "android.net.Uri"
   Obj1.Target = Obj1.RunStaticMethod("android.media.MediaPlayer", "create", args, types)
   Obj1.RunMethod("start")
End Sub

 

[hackhack]

Haha, that's brilliant agraham

 

[hackhack]

Better add some tags so people can find it if they search: play default notification sound audio

Ahem! actually ...

Sub Btn1_Click
   Dim Obj1 As Reflector
   Obj1.Target = Obj1.CreateObject("android.provider.Settings$System")
   Obj1.Target = Obj1.GetField("DEFAULT_NOTIFICATION_URI")
   Dim args(2) As Object
   args(0) = Obj1.GetContext
   args(1) = Obj1.Target
   Dim types(2) As String
   types(0) = "android.content.Context"
   types(1) = "android.net.Uri"
   Obj1.Target = Obj1.RunStaticMethod("android.media.MediaPlayer", "create", args, types)
   Obj1.RunMethod("start")
End Sub

Funny though, it crashes the emulator with a java.lang.NullPointerException but works fine on the phone.

 

[agraham]

I suspect that the content pointed to by the DEFAULT_NOTIFICATION_URI field does not exist on the emulator.

   Obj1.Target = Obj1.CreateObject("android.provider.Settings$System")
   Obj1.Target = Obj1.GetField("DEFAULT_NOTIFICATION_URI")
   Dim args(2) As Object
   args(0) = Obj1.GetContext
   args(1) = Obj1.Target
   Dim types(2) As String
   types(0) = "android.content.Context"
   types(1) = "android.net.Uri"
   Obj1.Target = Obj1.RunStaticMethod("android.media.MediaPlayer", "create", args, types)
   Obj1.RunMethod("start")
End Sub

Not much experience with reflection & system settings, but is it possible to use code similar to this example to setfield (assign default notification) instead of getfield to read it?
