How to play .wav file attached to (Voice over IP) voice-mail files in Android?

Question

need to play .wav file (attached to a voicemail) in a device with Android 4.3.1 (API 18) installed.

I am aware that there are some app like 'remote wav' that are able to play .wav file however I need to make this inbuilt feature for my app.

any help will be really appreciated; perhaps what I am looking for is to find out if there is a library to play .wav via default android Mediaplayer class or even first to convert it to any other format then play it ...

thanks for time in advance

I tried this:

public class MainActivity extends Activity {
    SoundPool mPlayer;
    int mSoundId ;
    Button play1;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mPlayer = new SoundPool(1, AudioManager.STREAM_MUSIC, 0);
        mSoundId = mPlayer.load(this, R.raw.s2, 1);
        Button play1 = (Button) this.findViewById(R.id.buttonPlay1);
        play1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                mPlayer.play(mSoundId, 0.99f, 0.99f, 0, 0, 1f);
            }
        });
    }
}

but does not work, I got

11-26 16:31:14.019 7971-7971 W/SoundPool:   sample 1 not READY

I think this type of wav (attached to voicemails) is different type and can not be handle by Mediaplayer/SoundPool. see https://www.onsip.com/blog/free-way-to-listen-to-wav-files-on-your-android-device I can attach the file (sample.wav) so you can try if you want.

edited: ------------------------ as Philip Sander suggested I tried Soundpool sample not ready but none of the replied answers worked for me (no sound output)

edited:-------------------------- I applied AudioTrack approach explained Using AudioTrack in Android to play a WAV file but the result was some statics noises (white noises only for few seconds) then I applied Android AudioTrack playing .wav file, getting only white noise , this asn this to fix the statics noise, however no luck, I am running out of idea and really appreciate new ones, this is a link to a sample wav file here

I will ignore this question from nowon because you show 0 effort to solve oyur own problems. — Philipp Sander, Nov 26 '15 at 16:41
well thanks for help anyway, not happy with your comment though, how did you conclude I put zero effort, the first link you provided I tried myself before posting this, in fact I spend couple of hours into this I wish you were more patient considering my ranking you should have a rough idea that I am new in development! — bastami82, Nov 26 '15 at 16:52

I don't think you need a library to play .wav files, the android.media.MediaPlayer can play WAV files normally the way other formats are played.

MediaPlayer player = MediaPlayer.create(this, R.raw.file_name);
    /*Then to start the player*/
player.start();
