Having SERIOUS trouble trying to play sound by string labels

Postby Cypha Signals » Wed May 05, 2010 9:17 am

Basically, I have this externalized array setup and I followed a fellow board members instruction on setting up the usage of that array.

The problem is I have no clue as to how android wants me to call that sound as a string rather than a int...

Array of 7 sounds -> dropped into random generation -> String is created -> play "string"...here's where I'm stuck

My java so far...

package com.cyphasignals.jelloman;

import com.cyphasignals.jelloman.SoundManager;
import java.util.Random;
import android.app.Activity;
import android.content.res.Resources;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;

public class JelloMan extends Activity {
private SoundManager mSoundManager;
/** Called when the activity is first created. */
private String[] myString;
private static final Random rgenerator = new Random();
public void onCreate(Bundle savedInstanceState) {

mSoundManager = new SoundManager();
mSoundManager.addSound(1, q);

ShakeListener MyShake = new ShakeListener((SensorManager) getSystemService(SENSOR_SERVICE));
MyShake.setOnShakeListener(new ShakeListener.OnShakeListener() {
public void onShake() {
ImageButton mouthbutton = (ImageButton)findViewById(R.id.billmouth);
mouthbutton.setOnClickListener(new OnClickListener() {

public void onClick(View v) {



Outsourced "SoundManager.java"
package com.cyphasignals.jelloman;

import java.util.HashMap;

import android.content.Context;
import android.media.AudioManager;
import android.media.SoundPool;

public class SoundManager {

private SoundPool mSoundPool;
private HashMap<Integer, Integer> mSoundPoolMap;
private AudioManager mAudioManager;
private Context mContext;

public SoundManager()


public void initSounds(Context theContext) {
mContext = theContext;
mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);
mSoundPoolMap = new HashMap<Integer, Integer>();
mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);

public void addSound(int Index,int SoundID)
mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1));


public void playSound(String q) {

int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(q), streamVolume, streamVolume, 1, 0, 1f);
public void stopSound(int Index, int SoundID) {


*If anyone knows a simpler way, it would be truly appreciated :)

Ignoring all else for a moment, is it really needed to play a sound via a String? I'm of course not sure of what you are implementing, but if its for the sake of being able to request a sound in your code via a nice readable tag, you could always use a list of statically defined integer tags as the keys:

public static int CRASH= 0;
public static int BEEP = 1;

That way in code, you could request to play a sound with the pre-defined tags as if they were strings. By the same token, you could always use String as the key type in the hashmap.

I apologize if this doesn't address your question / work with how you have your sound manager set up, thought I would post a quick response before I get another customer at work. ><
