Android Tutorial | Android SDK Development & Programming

This example shows how you can play sound using sound pool.

Algorithm:

1.) Create a new project by File-> New -> Android Project name it SoundPoolExample.

2.) Add a sound file to res/raw folder and name it to sound1.

3.) Write following into main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent">
	<TextView android:text="Click on the screen to start playing"
		android:id="@+id/textView1" android:layout_width="fill_parent"
		android:layout_height="fill_parent"></TextView>
</LinearLayout>

4.) Run for output.

Steps:

1.) Create a project named SoundPoolExample and set the information as stated in the image.

Build Target: Android 4.0
Application Name: SoundPoolExample
Package Name: com. example. SoundPoolExample
Activity Name: SoundPoolExample
Min SDK Version: 8

2.) Open SoundPoolExample.java file and write following code there:

package com.example.soundpoolexample;

import android.app.Activity;
import android.media.AudioManager;
import android.media.SoundPool;
import android.media.SoundPool.OnLoadCompleteListener;
import android.os.Bundle;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;

public class SoundPoolExample extends Activity implements OnTouchListener {
	private SoundPool soundPool;
	private int soundID;
	boolean loaded = false;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		View view = findViewById(R.id.textView1);
		view.setOnTouchListener(this);
		// Set the hardware buttons to control the music
		this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
		// Load the sound
		soundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
		soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
			@Override
			public void onLoadComplete(SoundPool soundPool, int sampleId,
					int status) {
				loaded = true;
			}
		});
		soundID = soundPool.load(this, R.raw.sound1, 1);

	}

	@Override
	public boolean onTouch(View v, MotionEvent event) {
		if (event.getAction() == MotionEvent.ACTION_DOWN) {
			// Getting the user sound settings
			AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
			float actualVolume = (float) audioManager
					.getStreamVolume(AudioManager.STREAM_MUSIC);
			float maxVolume = (float) audioManager
					.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
			float volume = actualVolume / maxVolume;
			// Is the sound loaded already?
			if (loaded) {
				soundPool.play(soundID, volume, volume, 1, 0, 1f);
				Log.e("Test", "Played sound");
			}
		}
		return false;
	}
}

3.) Compile and build the project.

4.) Make sure you run this app on actual device to get the sound played.
