By: Unknown 0 comments

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:

1 2 3 4 5 6 7 8

<?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:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58

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.
