Play a sound in Android when i start application

Question

I'm trying to play a music sound when my application starts. I used the code:

MediaPlayer mp = new MediaPlayer();
        MediaPlayer.create(this, R.raw.counting1to5song);
        mp.start();

and the song is in res/raw folder. But when I install the application in my phone and then open, the app crashes!!!

Anyone can give me any help to get this sound properly function?

All ready tried to looking to that question. But the app crashes when it starts too. I find Logcat in Android Studio but nothing apears. — Karga, Mar 31 '15 at 11:47
You're missing any kind of error handling. Don't take for granted that all API calls will succeed. For example, `MediaPlayer.create` will return `null` if it fails, and `MediaPlayer.start` will throw an exception if you call it when the media player is in the wrong state. — Michael, Mar 31 '15 at 15:30

mMediaPlayer = MediaPlayer.create(this, R.raw.sound1);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setLooping(true);

The same problem. The app crashes when starts. But when i put that code in "new MediaPlayer();" is saying that the variable is redundant. – Karga Mar 31 '15 at 11:48

Create a new folder called "raw" inside "debug" folder. To create it, right-click on "debug" folder > new > directory > and in name it "raw":

To add files just drag the .wav/.mp3 files to "raw" folder.

Import media player:

import android.media.MediaPlayer;

Declare MediaPlayer global variable(s):

public MediaPlayer mp1;

Inside onCreate method, assign the corresponding sounds:

mp1 = MediaPlayer.create(MainActivity.this, raw.my_sound_name);

Finally, you can use methods:

mp1.start() / mp1.stop() / mp1.pause()
