Question

my problem is a little bit tricky to describe.

I have a separated resources folder in my project (and in the apk-file).

String path = "/resources/instruments/data/bongo/audio/bong1.wav";  

I can already use it with

url = StreamHelper.class.getClassLoader().getResource( path );
url.openStream();

but actually I want to load the file into the SoundPool.
I tried it this way:

SoundPool soundPool = new SoundPool(  5, AudioManager.STREAM_MUSIC, 0 );  
soundPool.load ( path, 1 );

… but i always get an error information: “error loading /resourc…”

load(String path, int )
On this link I’ve seen that I need the correct path for File

File file = new File( path );
if( file.exists() ) 
     //always false but i thing if it would be true soundPool.load should work too

Now my question: how has the path to be that it works. Or is there any other idea for my problem (p.e. with the AssetManager) ?

Btw. I know that there are special Android ways to get resources like R.id.View … but in my case it would be not easy to handle.

Thanks!

Personally, I don’t see WAV files as ‘resources’ and I’d suggest you put them in the ‘assets’ folder and use AssetManager as you mentioned.

This works for me…

Create a folder structure in your project…

    /assets/instruments/data/bongo/audio

…then copy your bong1.wav file there.

Use the following to load it. NOTE: DO NOT put ‘/’ in front of ‘instruments’ when supplying the path to soundPool.load()…

    // Declare globally if needed
    int mySoundId;
    SoundPool soundPool = new SoundPool(5, AudioManager.STREAM_MUSIC, 0 );
    AssetManager am = this.getAssets();

    //Use in whatever method is used to load the sounds
    try {
        mySoundId = soundPool.load(am.openFd("instruments/data/bongo/audio/bong1.wav"), 1);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Use this to play it…

    soundPool.play(mySoundId, 1, 1, 0, 0, 1);
