Sound Pool Example in Andrpoi


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, intsampleId,
                                        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.
