It's a example to play a single note in RTTTL format using MediaPlayer.



First, create a xml(/res/raw/a4.rtttl) to define a single note in RTTTL format.

<a4:d=4,o=5,b=250:a4;

Main Code:

package com.exercise.AndroidRTTTL;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class AndroidRTTTLActivity extends Activity {
 
 Button buttonPlay;
 MediaPlayer mediaPlayer;
 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        buttonPlay = (Button)findViewById(R.id.play);
        buttonPlay.setOnClickListener(buttonPlayOnClickListener);
    }
    
    Button.OnClickListener buttonPlayOnClickListener
    = new Button.OnClickListener(){

  @Override
  public void onClick(View arg0) {
   // TODO Auto-generated method stub
   if(mediaPlayer != null) 
   {
    mediaPlayer.release();
   }
   
   mediaPlayer = MediaPlayer.create(AndroidRTTTLActivity.this, R.raw.a4);
   mediaPlayer.start();
   
  }};
}

Layout, main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />
    <Button
        android:id="@+id/play" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Play" />
