Android Question [Solved] Sound Pool loading delay.

vfafou · Mar 30, 2017

Hello!
I'm trying to load ~180 ogg files to the sound pool of audio library. Some devices do it within 1 second but for some others there is a delay of 30-50 seconds.
I think I have to load them asynchronously but there is not any method in library to allow this.
What else could I do?

Thank you in advance!

If I remember correctly the sounds are already loaded asynchronously, you can implement a callback using Javaobject when the load is complete, There is an example in this thread: https://www.b4x.com/android/forum/threads/multitrigger-soundpool-example.42038/

How are you loading the sounds? Is there a delay in Debug or release mode?

Hello stevel05!
Thank you for the very fast response!
The delay is appeared in both modes.
During the loading, the UI stops responding, but I don't want to put a DoEvents!

I am out for the rest of the day, if you don't get another answer I'll take a look this evening, but can you post your loading code. It will help us to help you.

OK, my code is similar to:

B4X:

For i = 1 to 180
  SMap.Put(i & "Normal.ogg",SndPool.Load(i & "Normal.ogg"))
Next

I put the LoadId in a map using the file name as key.

Maybe load the files when they are first needed:

B4X:

Sub GetAudioId(Name As String) As Int
 If SMap.ContainsKey(Name) = False Then Smap.Put(Name, SndPool.Load(...))
 Return Smap.Get(Name)
End Sub

Hi, Erel!
Thank you for your brain-unstucking instructions! You help is brilliantly precious!

Detected a problem! When I first put an object to the map, there's no sound playing. I think it doesn't load the files so fast!

Check the link in post #2, it provides a method to get a callback when the file is loaded.

Thank you again stevel05!
I've already done it! It's working like a charm!
