I am have a few wav files that I want to load with the help of Android's asset manager. Unfortunately, everytime I try to do so, I get the following error
java.io.FileNotFoundException: audio-file.wav not found
I would like to add the following assets to the Android sound pool.
This is the image of my application set up.
My code
public class MyActivity extends AppCompatActivity {
protected abstract Fragment createFragment();
@LayoutRes
protected int getLayoutRes() {
return R.layout.activity_fragment;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(getLayoutRes());
FragmentManager fm = getSupportFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.fragment_container);
if (fragment == null) {
fragment = new MyActivityFragment();
fm.beginTransaction().add(R.id.fragment_container, fragment).commit();
}
}
}
Fragment
public class MyActivityFragment extends Fragment {
private static final String TAG = "MyFragment";
private static final String SOUNDS_FOLDER = "sample_sounds";
private static final int MAX_SOUNDS = 5;
private final AssetManager mAssetManager;
private final List<Integer> sounds = new ArrayList<>();
private SoundPool mSoundPool;
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRetainInstance(true);
this.mAssetManager = getActivity().getAssets();
this.loadAssets();
mSoundPool = this.buildSoundPool();
}
@Override
public void onDestroy() {
super.onDestroy();
mSoundPool.release();
}
private SoundPool buildSoundPool() {
SoundPool.Builder builder = new SoundPool.Builder();
builder.setMaxStreams(MAX_SOUNDS);
builder.setAudioAttributes(new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_MEDIA)
.setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
.build());
return builder.build();
}
private void loadAssets() {
try {
String[] soundNames = mAssetManager.list(SOUNDS_FOLDER);
for (String soundName : soundNames) {
sounds.add(load(soundName));
}
} catch (IOException ioe) {
Log.e(TAG, "Could not list assets");
}
}
private int load(String soundName) throws IOException {
AssetFileDescriptor afd = mAssetManager.openFd(soundName);
int soundId = mSoundPool.load(afd, 1);
return soundId;
}
}
This method raises a FileNotFoundException
.
private int load(String soundName) throws IOException {
AssetFileDescriptor afd = mAssetManager.openFd(soundName);
int soundId = mSoundPool.load(afd, 1);
return soundId;
}
This line precisely
AssetFileDescriptor afd = mAssetManager.openFd(soundName);
I have gone through the other posts related to this issue, but the most recent post is at least 3 years old. I don't know what I am doing wrong. Any help would be gratefully appreciated.

IIRC, list()
returns the names of the items in the asset directory. It does not return the paths of those items.
Try replacing:
AssetFileDescriptor afd = mAssetManager.openFd(soundName);
with:
AssetFileDescriptor afd = mAssetManager.openFd(SOUND_FOLDER+"/"+soundName);
