Play audio using MediaPlayer

To play audio in Android, we can use MediaPlayer. Base on the audio file from last exercise "Start audio recording with intent of MediaStore.Audio.Media.RECORD_SOUND_ACTION", modify to add a Play button to start audio playback using MediaPlayer. Additionally, we have to implement MediaPlayer.OnCompletionListener() method to handle the OnCompletion event.

Play audio using MediaPlayer

package com.exercise.AndroidIntentAudioRecording;

import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class AndroidIntentAudioRecording extends Activity {

final static int RQS_RECORDING = 1;

Uri savedUri;

Button buttonRecord, buttonPlay;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
buttonRecord = (Button)findViewById(R.id.record);
buttonPlay = (Button)findViewById(R.id.play);
buttonPlay.setEnabled(false);

buttonRecord.setOnClickListener(new Button.OnClickListener(){

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent =
new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
startActivityForResult(intent, RQS_RECORDING);
}});

buttonPlay.setOnClickListener(new Button.OnClickListener(){

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
MediaPlayer mediaPlayer = MediaPlayer.create(AndroidIntentAudioRecording.this, savedUri);
mediaPlayer.setOnCompletionListener(completionListener);
mediaPlayer.start();
buttonRecord.setEnabled(false);
buttonPlay.setEnabled(false);
}});
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
if(requestCode == RQS_RECORDING){
if(resultCode == RESULT_OK){
savedUri = data.getData();
buttonPlay.setEnabled(true);
Toast.makeText(AndroidIntentAudioRecording.this,
"Saved: " + savedUri.getPath(),
Toast.LENGTH_LONG).show();
}else{
buttonPlay.setEnabled(false);
Toast.makeText(AndroidIntentAudioRecording.this,
"User Cancelled!",
Toast.LENGTH_LONG).show();
}

}
}

MediaPlayer.OnCompletionListener completionListener
= new MediaPlayer.OnCompletionListener(){

@Override
public void onCompletion(MediaPlayer arg0) {
// TODO Auto-generated method stub
buttonRecord.setEnabled(true);
buttonPlay.setEnabled(true);
}};

}
