Android Question OpenSLSoundPlayer: FileNotFoundException

danijel · Oct 21, 2018

I am using OpenSLSoundPlayer Lib to play simple sounds.
Everything works great in Release Mode. But when I switch to Debug Mode I get an Exception:

Logs:

B4X:

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Error occurred on line: 32 (Main)
java.io.FileNotFoundException: down.wav

** Activity (main) Resume **

Code:

B4X:

Sub Globals

    Dim SP As OpenSLSoundPlayer
    Dim SND As Int

End Sub

Sub Activity_Create(FirstTime As Boolean)
    
    SP.Initialize(8, False)
    SND=SP.LoadSoundFromAssets("down.wav")
    SP.Play(SND, 1, 0)
    
End Sub

down.wav is in Default Group in Assets Files.
What is wrong with this?

You may want to test if this makes any difference

B4X:

#DebuggerForceStandardAssets: True

Thank you, but no difference :/

I had same kind of problem with one of my app. If I remember correctly I never did solve the problem, so I just copied files to DirInternal and used them from there.
You can just check every time app starts that files exists in DirInternal if not then use copy.

In fact that works as a workaround solution. Thank you!

Hello Danijel.

You can put the code to resolve that issue. Because I got the same problem.

Thank's a lot.

    SP.Initialize(8, True)
    MySound = SP.LoadSoundFromDisk(File.DirInternal & "/" & "snd.wav")
    SP.Play(MySound, 1, 0)
End Sub

This should work. Just keep this in mind:

Thank's a lot Danijel for you response. I will change my code...
