SoundPool Question

walterf25 · Mar 22, 2013

Hello All, i have this code on an activity, but the sound doesn't play when the activity is started.

B4X:

Activity.LoadLayout("Green1")
   sp.Initialize(1)
   sound = sp.Load(File.DirAssets, "ding.mp3")
   sp.Play(sound, 1, 1, 1, 0, 1)

but if i put the

sp.play(sound, 1, 1, 1, 0, 1)

inside a Sub Button1_click then it plays when i click the button, i'm confused why won't the sound play as soon as the activity starts?

Any thoughts?

Thanks
Walter

The native SoundPool has some issues. Try to change the volume and also try to convert your file to OGG instead of mp3.

Soundpool is not like Media Player in that when you issue the Load command, it decompresses the whole sound into memory before it can play. There is a related thread here with a couple of possible solutions, although if you choose the second one, I would use a timer rather than a loop to test if it's loaded.

If this introduces too much delay, I would suggest using media player for this purpose.

Don't put sp.Play in Activity_Create. It's not the place for it. Move it in Activity_Resume and that should work.

soundpool issue

Hi all, thanks for all the suggestions, @informatix, i actually tried putting the

sp.play

command in the Activity_Resume but in did not work either. I finally got it working this way.

I had to initialize the sp variable in the Sub_Globals and load the .mp3 files from the main activity, then when i call them from the other two activities like this
called from Green1 activity

B4X:

Main.sp.Play(Main.loadid, 1, 1, 1, 0, 1)

and this called from Red1 Activity

B4X:

Main.sp1.Play(Main.loadid1, 1, 1, 1, 0, 1)

and this workd good, i'm not sure why but it works, :sign0060:

Thanks all for your help!

It's strange because I used SoundPool in many cases in my recent app and never had a problem like this. But it's fine if that works that way.
